+      <ul>
+        <li>Made GCC 4.8 the default for all 32-bit ABIs.  Deprecated GCC 4.6, and
+            will remove it next release. To restore previous behavior, either add
+            <code>NDK_TOOLCHAIN_VERSION=4.6</code> to ndk-build, or
+            add <code>--toolchain=arm-linux-androideabi-4.6</code> when executing
+            <code>make-standalone-toolchain.sh</code> on the command line. GCC 4.9 remains the
+            default for 64-bit ABIs.</li>
+
+         <li>Stopped all x86[_64] toolchains from adding <code>-mstackrealign</code> by default. The
+             NDK toolchain assumes a 16-byte stack alignment. The tools and options used by default
+             enforce this rule. A user writing assembly code must make sure to preserve stack
+             alignment, and ensure that other compilers also comply with this rule.
+             (GCC bug <a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=38496">38496</a>)</li>
+
+         <li>Added Address Sanitizer functionality to Clang 3.5 support to the ARM and x86 ABIs.
+             For more information on this change, see the
+             <a href="https://code.google.com/p/address-sanitizer/wiki/Android">Address
+             Sanitizer</a> project.</li>
+
+         <li>Introduced the requirement, starting from API level 21, to use <code>-fPIE -pie
+             </code> when building. In API levels 16 and higher, ndk-build uses <code>PIE</code>
+             when building. This change has a number of implications, which are discussed in
+             <a href="https://code.google.com/p/android-developer-preview/issues/detail?id=888">
+             Developer Preview Issue 888</a>.

+            A53 Errata #835769</a> in the aarch64-linux-android-4.9 linker. As part of this, GCC
+            passes a new option, <code>--fix-cortex-a53-835769</code>, when
+            <code>-mfix-cortex-a53-835769</code> (enabled by default) is specified.

+           <ul>
+        <li>Added <code>posix_memalign</code> to API level 16. Also, added a prototype in

+           </ul>
+
+        <li>Fixed ndk-build's handling of <code>thumb</code> for <code>LOCAL_ARM_MODE</code>: In
+            r10d, ndk-build adds <code>LOCAL_LDFLAGS+=-mthumb</code> by default, unless one of the
+            following conditions applies:</li>
+          <ul>
+            <li>You have set <code>LOCAL_ARM_MODE</code> equal to <code>arm</code>.</li>
+            <li>You are doing a debug build (with settings such as <code>APP_OPTIM=debug</code> and
+            <code>AndroidManifest.xml</code> containing <code>android:debuggable="true"</code>),
+            where ARM mode is the default in order to retain compatibility with earlier toolchains.

+      <dd>
+      <ul>
+ <li>Made the following changes to download structure:</li>
+       <ul>
+       <li>Each package now contains both the 32- and the 64-bit headers, libraries, and tools for
+       its respective platform.</li>
+       <li>STL libraries with debugging info no longer need be downloaded separately.</li>
+       </ul>
+  <li>Changed everything previously called <code>Android-L</code> to the official release
+  designation: <code>android-21</code>.</li>
+  <li>Updated GCC 4.9 by rebasing to the <code>google</code> branch
+  of the GCC repository. Major differences from the upstream version of GCC 4.9 include:</li>
+
+  <ul>
+  <li>The <code>-O2</code> option now turns on vectorization, without loop peeling but with more
+  aggressive unrolling.</li>
+  <li>Enhancements to FDO and <a href="https://gcc.gnu.org/wiki/LightweightIpo#LIPO_-_Profile_Feedback_Based_Lightweight_IPO">
+  LIPO</a></li>
+  <p>For more detailed information, see <em>Important bug fixes</em> below.</p>
+  </ul>
+
+  <li>Added Clang 3.5 support to all hosts: <code>NDK_TOOLCHAIN_VERSION=clang</code>
+  now picks Clang 3.5. Note that:</li>
+  <ul>
+
+  <li>ARM and x86 default to using the integrated assembler. If this causes issues, use
+  <code>-fno-integrated-as</code> as a workaround.</code>
+  <li>Clang 3.5 issues more warnings for unused flags, such as the <code>-finline-functions</code>
+  option that GCC supports.</li>
+  <p>When migrating from projects using GCC, you can use
+  <code>-Wno-invalid-command-line-argument</code> and <code>-Wno-unused-command-line-argument</code>
+  to ignore the unused flags until you're able decide on what to do with them longer-term.</p>
+
+     </ul>
+  <li>Made it possible to enter ART debugging mode, when debugging on an Android 5.0 device using
+  ART as its virtual machine, by specifying the <code>art-on</code> option. For more information,
+  see <code>prebuilt/common/gdb/common.setup</code> in the directory containing the NDK.</li>
+  <li>Removed support for Clang 3.3.</li>
+  <li>Deprecated GCC 4.6, and may remove it from future releases.</li>
+  <li>Updated mclinker to 2.8 with Identical Code Folding ("ICF") support. Specify ICF using the
+  <code>--icf</code> option.</li>
+  <li>Broadened <code>arm_neon.h</code> support in x86 and x86_64, attaining coverage of ~93% of
+  NEON intrinsics. For more information about NEON support:
+     <ul>
+     <li>Navigate to the NDK Programmer's Guide (<code>docs/Programmers_Guide/html/</code>), and see
+     Architectures and CPUs > Neon.</li>
+     <li>Examine the updated <code>hello-neon</code> sample in <code>samples/</code>.

+     </ul>
+  <li>Documented support for <code>_FORTIFY_SOURCE</code> in <code>headers/libs/android-21</code>,

+      <ul>
+        <li>Added 3 new ABIs, all 64-bit: arm64-v8a, x86_64, mips64.</li> Note that:
+        <ul>
+           <li>GCC 4.9 is the default compiler for 64-bit ABIs. Clang is currently version 3.4.
+<code>NDK_TOOLCHAIN_VERSION=clang</code>
+      may not work for arm64-v8a and mips64.</li>
+           <li>Android-L is the first level with 64-bit support.  Note that this API
+level is a temporary one, and only for L-preview. An actual API level number will replace it at
+L-release.</li>
+           <li>This release includes now includes <code>all32</code> and <code>all64</code>
+settings for <code>APP_ABI</code>.
+              <ul>
+              <li><code>APP_ABI=all32</code> is equivalent to
+<code>APP_ABI=armeabi,armeabi-v7a,x86,mips</code>.</li>
+              <li><code>APP_ABI=all64</code> is equivalent to
+<code>APP_ABI=arm64-v8a,x86_64,mips64</code>.</li>
+              <li><code>APP_ABI=all</code> selects all ABIs.</li>
+              </ul>
+           <li>The new GNU libstdc++ in Android-L contains all <code>&lt;tr1/cmath&gt;</code>
+Before defining your own math function, check <code>_GLIBCXX_USE_C99_MATH_TR1</code> to see a
+function with that name already exists, in order to avoid "multiple definition" errors from the
+linker.</li>
+           <li>The cpu-features library has been updated for the ARMv8 kernel.  The existing
+cpu-features library may fail to detect the presence of NEON on the ARMv8 platform. Recompile your
+code with the new version.</li>
+        </ul>
+        <li>Added a new <code>platforms/android-L/</code> API directory. It includes:</li>
+        <ul>
+           <li>Updated Bionic headers, which had not changed from Android API levels 3
+(Cupcake) to 19 (KitKat). This new version, for level L, is to be synchronized with AOSP.</li>
+           <li>New media APIs and a native-codec sample.</li>
+           <li>An updated <code>Android.h</code> header for SLES/OpenSLES, enabling support for
+single-precision, floating-point audio format in AudioPlayer.</li>
+           <li>GLES 3.1 and AEP extensions to <code>libGLESv3.so.</code></li>
+           <li>GLES2 and GLES3 headers updated to the latest official Khronos versions.</li>
+        </ul>
+        <li>Added GCC 4.9 compilers to the 32-/64-bit ABIs.  GCC 4.9 is the default (only) compiler
+for 64-bit ABIs, as previously mentioned.  For 32-bit ABIs, you must explcitly enable GCC 4.9, as
+GCC 4.6 is still the default.</li>
+        <ul>
+           <li>For ndk-build, enable 32-bit, GCC 4.9 building either by adding
+<code>NDK_TOOLCHAIN_VERSION=4.9</code> to <code>Application.mk</code>, or exporting it as an
+environment variable from the command line.</li>
+           <li>For a standalone toolchain, use the <code>--toolchain=</code> option in the
+<code>make-standalone-toolchain.sh</code> script. For example: <code>--toolchain=arm-linux-androideabi-4.9.</code></li>
+        </ul>
+        <li>Upgraded GDB to version 7.6 in GCC 4.8/4.9 and x86*. Since GDB is still at version GDB-7.3.x in
+GCC 4.6 (the default for ARM and MIPS), you must set
+<code>NDK_TOOLCHAIN_VERSION=4.8</code> or <code>4.9</code> to enable ndk-gdb to select GDB 7.6.</li>
+        <li>Added the <code>-mssse3</code> build option to provide SSSE3 support, and made it the default for ABI x86
+(upgrading from SSE3). The image released by Google does not contain SSSE3 instructions.</li>
+        <li>Updated GCC 4.8 to 4.8.3.</li>
+        <li>Improved ARM libc++ EH support by switching from gabi++ to libc++abi. For details, see the "C++ Support" section of the documentation.
+  Note that:</li>
+        <ul>
+           <li>All tests except for locale now pass for Clang 3.4 and GCC 4.8. For more
+information, see the "C++ Support" section of the documentation.</li>
+           <li>The libc++ libraries for X86 and MIPS libc++ still use gabi++.</li>
+           <li>GCC 4.7 and later can now use &lt;atomic&gt;.</li>
+           <li>You must add <code>-fno-strict-aliasing</code> if you use <code> &lt;list&gt;</code>, because <code>__list_imp::_end</code>_ breaks
+      TBAA rules.  (Issue <a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61571">61571</a>.)</li>
+           <li>As of GCC 4.6, LIBCXX_FORCE_REBUILD:=true no longer rebuilds libc++. Rebuilding it
+requires the use of a different compiler. Note that Clang 3.3 is untested.</li>
+        </ul>
+        <li>mclinker is now version 2.7, and has aarch64 Linux support.</li>
+        <li>Added precompiled header support for headers specified by <code>LOCAL_PCH</code>.  (Issue <a href="http://b.android.com/25412">25412</a>).</li>

+       <li>Fixed Clang 3.4 inability to compile with <code>-Wl,-shared</code> (as opposed to
+<code>-shared</code>, which
+  had no compilation issues).  The problem was that Clang added <code>-pie</code> for Android
+targets if neither <code>-shared</code> nor <code>-static</code> existed. This behavior, which was
+incorrect, caused the linker to complain that <code>-shared</code> and <code>-pie</code> could not
+co-exist.</li>

+Neon. There is currently no support for 64-bit types. For more information, see the section on ARM
+Neon intrinsics support in the x86 documentation.</li>
+        <li>Ported ARM/GOT_PREL optimization (present in GCC 4.6 built from the GCC google branch) to

+      <ul>
+        <li>Added support for the Clang 3.4 compiler. The
+<code>NDK_TOOLCHAIN_VERSION=clang</code> option now picks Clang 3.4. GCC 4.6 is
+still the default compiler.</li>
+        <li>Added <code>APP_ABI=armeabi-v7a-hard</code>, with
+additional multilib option <code>-mfloat-abi=hard</code>. These options are for
+use with ARM GCC 4.6/4.8 and Clang 3.3/3.4 (which use 4.8's assembler, linker,
+and libs). When using these options, note the following changes:</li>
+        <ul>
+           <li> When executing the <code>ndk-build</code> script, add the
+following options for armeabi-v7a target:
+<pre>TARGET_CFLAGS += -mhard-float -D_NDK_MATH_NO_SOFTFP=1
+TARGET_LDFLAGS += -Wl,--no-warn-mismatch -lm_hard</pre>
+The built library is copied to <code>libs/armeabi-v7a</code>. For make to
+behave as expected, you cannot specify both <code>armeabi-v7a</code> and
+<code>armeabi-v7a-hard</code> as make targets (i.e., on the APP_ABI= line).
+Doing so causes one of them to be ignored. Note that <code>APP_ABI=all</code>
+is still equivalent to
+<code>armeabi armeabi-v7a x86 mips</code>.</li>
+           <li>The <code>make-standalone-toolchain.sh</code> script copies
+additional libaries under <code>/hard</code> directories.
+      Add the above <code>CFLAGS</code> and <code>LFLAGS</code> to your
+makefile to enable GCC or Clang to link with
+      libraries in <code>/hard</code>.</li>
+        </ul>
+        <li>Added the yasm assembler, as well as <code>LOCAL_ASMFLAGS</code>
+and <code>EXPORT_ASMFLAGS</code> flags for x86
+targets. The <code>ndk-build</code> script uses
+<code>prebuilts/*/bin/yasm*</code> to build <code>LOCAL_SRC_FILES</code> that
+have the <code>.asm</code> extension.</li>
+        <li>Updated MClinker to 2.6.0, which adds <code>-gc-sections</code>
+support.</li>
+        <li>Added experimental libc++ support (upstream r201101).  Use this new
+feature by following these steps:
+        <ul>
+           <li>Add <code>APP_STL := c++_static</code> or <code>APP_STL :=
+c++_shared</code> in <code>Application.mk</code>.

+true</code></li>

+     <ul>
+       <li>Fixed a problem with GCC 4.8 ARM, in which the stack pointer is
+restored too early. This problem prevented the frame pointer from reliably
+accessing a variable in the stack frame. (GCC Issue <a
+href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58854">58854</a>)</li>
+<li>Fixed a problem with GCC 4.8 libstdc++, in which a bug in
+std::nth_element was causing generation of code that produced a random
+segfault. (Issue <a
+href="https://code.google.com/p/android/issues/detail?id=62910">62910</a>)</li>
+           <li>Fixed GCC 4.8 ICE in cc1/cc1plus with
+<code>-fuse-ld=mcld</code>, so that the following error no longer occurs:
+<pre>cc1: internal compiler error: in common_handle_option, at
+opts.c:1774</pre></li>

+     <ul>
+       <li>Header fixes:
+         <ul>
+           <li>Changed prototype of <code>poll</code> to <code>poll(struct
+pollfd *, nfds_t, int);</code> in <code>poll.h</code>.</li>
+           <li>Added <code>utimensat</code> to <code>libc.so</code> for Android
+API levels 12 and 19. These libraries are now included for all Android API
+levels 12 through 19.</li>
+<li>Introduced <code>futimens</code> into <code>libc.so</code>, for Android API
+level 19.</li>
+<li>Added missing <code>clock_settime()</code> and
+<code>clock_nanosleep()</code> to <code>time.h</code> for Android API level 8
+and higher.</li>
+<li>Added <code>CLOCK_MONOTONIC_RAW, CLOCK_REALTIME_COARSE,
+CLOCK_MONOTONIC_COARSE, CLOCK_BOOTTIME, CLOCK_REALTIME_ALARM,</code> and
+<code>CLOCK_BOOTTIME_ALARM</code> in <code>time.h.</code></li>
+<li>Removed obsolete <code>CLOCK_REALTIME_HR</code> and
+<code>CLOCK_MONOTONIC_HR.</code></li>
+         </ul>
+       </li>
+       <li>In samples Teapot, MoreTeapots, and
+<code>source/android/ndk_helper</code>:
+         <ul>
+<li>Changed them so that they now use a hard-float abi for armeabi-v7a.</li>
+<li>Updated them to use immersive mode on Android API level 19 and
+higher.</li>
+<li>Fixed a problem with <code>Check_ReleaseStringUTFChars</code> in
+<code>/system/lib/libdvm.so</code> that was causing crashes on x86 devices.</li>
+         </ul>
+        </li>
+<li>Fixed <code>ndk-build</code> fails that happen in cygwin when the NDK
+package is
+referenced via symlink.</li>
+<li>Fixed <code>ndk-build.cmd</code> fails that happen in windows
+<code>cmd.exe</code> when
+<code>LOCAL_SRC_FILES</code> contains absolute paths. (Issue <a
+href="https://android-review.googlesource.com/#/c/69992">69992</a>)</li>
+<li>Fixed the <code>ndk-stack</code> script to proceed even when it can't parse
+a frame due to inability to find a routine, filename, or line number. In any of
+these cases, it prints <code>??</code>.</li>
+<li>Fixed the <code>ndk-stack</code> stack for windows-x64_64 targets so that
+it no longer erroneously matches a frame line with a line in the
+<code>stack:</code> section that doesn't contain <code>pc</code>,
+<code>eip</code>, or <code>ip</code>. For example:
+<pre>I/DEBUG   ( 1151):     #00  5f09db68  401f01c4
+/system/lib/libc.so</pre></li>
+<li>Fixed gabi++ so that it:
+     <ul>
+         <li>Does not use malloc() to allocate C++ thread-local
+  objects.</li>
+         <li>Avoids deadlocks in gabi++ in cases where libc.debug.malloc is
+non-zero in userdebug/eng Android platform builds.</li>

+     </dd>
+
+     <dt>Other changes:</dt>
+     <dd>
+     <ul>
+       <li>Added <code>LOCAL_EXPORT_LDFLAGS</code>.</li>
+<li>Introduced the <code>NDK_PROJECT_PATH=null</code> setting for use in an
+integrated build system where options are explicitly passed to
+<code>ndk-build</code>. With this setting, <code>ndk-build</code> makes no
+attempt to look for <code>NDK_PROJECT_PATH.</code> This setting also prevents
+variables from deriving default settings from NDK_PROJECT_PATH. As a result,
+the following variables must now be explicitly specified (with their default
+values if such exist): <code>NDK_OUT, NDK_LIBS_OUT, APP_BUILD_SCRIPT,
+NDK_DEBUG</code> (optional, default to 0), and other <code>APP_*</code>'s
+contained in <code>Application.mk</code>.</li>
+<li><code>APP_ABI</code> can now be enumerated in a comma-delimited list. For
+example:
+<pre>APP_ABI := "armeabi,armeabi-v7a"</pre></li>
+<li>Provided the ability to rebuild all of STL with debugging info in an
+optional, separate package called
+<code>android-ndk-r9c-cxx-stl-libs-with-debugging-info.zip</code>, using the
+<code>-g</code> option. This option
+helps the <code>ndk-stack</code> script provide better a stack dump across STL.
+This change should not affect the code/size of the final, stripped file.</li>
+<li>Enhanced <code>hello-jni</code> samples to report <code>APP_ABI</code> at
+compilation.</li>
+<li>Used the <code>ar</code> tool in Deterministic mode (option
+<code>-D</code>) to build static libraries.  (Issue <a
+href="http://b.android.com/60705">60705</a>)</li>

+LOCAL_LDFLAGS += -fopenmp
+</pre>

+        <li>Added <code>LOCAL_CONLYFLAGS</code> and <code>APP_CONLYFLAGS</code> to specify
+          options applicable to C only but not C++. The existing <code>LOCAL_CFLAGS</code>
+          and <code>APP_CFLAGS</code> are also used for C++ compilation (to save trouble of

+      <dt>Important changes:</dt>
+      <dd>
+        <ul>
+          <li>Added support for Android 4.3 (API level 18). For more information, see
+            {@code STABLE-APIS.html} and new code examples in {@code samples/gles3jni/README}.
+          <li>Added headers and libraries for OpenGL ES 3.0, which is supported by Android 4.3
+            (API level 18) and higher.</li>
+          <li>Added GNU Compiler Collection (GCC) 4.8 compiler to the NDK. Since GCC 4.6 is still
+            the default, you must explicitly enable this option:
+            <ul>
+              <li>For {@code ndk-build} builds, export {@code NDK_TOOLCHAIN_VERSION=4.8} or
+                add it in {@code Application.mk}.</li>
+              <li>For standalone builds, use the {@code --toolchain=} option in
+                {@code make-standalone-toolchain.sh}, for example:<br>
+                {@code --toolchain=arm-linux-androideabi-4.8}</li>
+            </ul>
+            <p class="note"><strong>Note:</strong>
+            The {@code -Wunused-local-typedefs} option is enabled by {@code -Wall}. Be
+            sure to add {@code __attribute__((unused))} if you use compile-time asserts like
+            {@code sources/cxx-stl/stlport/stlport/stl/config/features.h}, line #311. For more
+            information, see
+            <a href="https://android-review.googlesource.com/#/c/55460">Change 55460</a></p>
+            <p class="note"><strong>Note:</strong>
+            In the GCC 4.7 release and later, ARM compilers generate unaligned access code by
+            default for ARMv6 and higher build targets. You may need to add the
+            {@code -mno-unaligned-access} build option when building for kernels that do not support
+            this feature.</p>
+          </li>
+          <li>Added Clang 3.3 support. The {@code NDK_TOOLCHAIN_VERSION=clang} build option
+            now picks Clang 3.3 by default.
+            <p class="note"><strong>Note:</strong>
+             Both GCC 4.4.3 and Clang 3.1 are deprecated, and will be removed from the next NDK
+             release.</p></li>
+          <li>Updated GNU Project Debugger (GDB) to support python 2.7.5.</li>
+          <li>Added MCLinker to support Windows hosts. Since {@code ld.gold}
+            is the default where available, you must add {@code -fuse-ld=mcld} in
+            {@code LOCAL_LDFLAGS} or {@code APP_LDFLAGS} to enable MCLinker.</li>
+          <li>Added {@code ndk-depends} tool which prints ELF library dependencies.
+            For more information, see {@code NDK-DEPENDS.html}.

+            (<a href="http://b.android.com/41755">Issue 41755</a>)</li>
+          <li>Fixed ARM/GCC-4.7 build to generate sufficient alignment for NEON load and store
+            instructions VST and VLD.
+            (<a href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57271">GCC Issue 57271</a>)</li>
+          <li>Fixed a GCC 4.4.3/4.6/4.7 internal compiler error (ICE) for a constant negative index

+            (<a href="http://b.android.com/54623">Issue 54623</a>)</li>
+          <li>Fixed GCC 4.7 segmentation fault for constant initialization with an object address.
+            (<a href="http://b.android.com/56508">Issue 56508</a>)</li>
+          <li>Fixed GCC 4.6 ARM segmentation fault for <code>-O</code> values when using Boost
+            1.52.0. (<a href="http://b.android.com/42891">Issue 42891</a>)
+          <li>Fixed {@code libc.so} and {@code libc.a} to support the {@code wait4()} function.
+            (<a href="http://b.android.com/19854">Issue 19854</a>)</li>

+          <li>Fixed {@code LOCAL_SHORT_COMMANDS} bug where the {@code linker.list} file is
+            empty or not used.</li>
+          <li>Fixed GCC MIPS build on Mac OS to use CFI directives, without which
+            {@code ld.mcld --eh-frame-hdr} fails frequently.</li>
+          <li>Fixed Clang 3.2 X86/MIPS internal compiler error in {@code llvm/lib/VMCore/Value.cpp}.
+            (<a href="https://android-review.googlesource.com/#/c/59021">Change 59021</a>)</li>
+          <li>Fixed GCC 4.7 64-bit Windows assembler crash. (Error: {@code out of memory allocating
+            4294967280 bytes}).</li>
+          <li>Updated {@code ndk-gdb} script so that the {@code --start} or {@code --launch} actions
+            now wait for the GNU Debug Server, so that it can more reliably hit breakpoints set
+            early in the execution path (such as breakpoints in JNI code).
+            (<a href="http://b.android.com/41278">Issue 41278</a>)
+            <p class="note"><strong>Note:</strong>
+              This feature requires jdb and produces warning about pending breakpoints.
+              Specify the {@code --nowait} option to restore previous behavior.
+            </p>
+          </li>
+          <li>Fixed GDB crash when library list is empty.</li>
+          <li>Fixed GDB crash when using a {@code stepi} command past a {@code bx pc} or
+            {@code blx pc} Thumb instruction.
+            (<a href="http://b.android.com/56962">Issue 56962</a>,
+             <a href="http://b.android.com/36149">Issue 36149</a>)</li>
+          <li>Fixed MIPS {@code gdbserver} to look for {@code DT_MIPS_RLD_MAP} instead of
+            {@code DT_DEBUG}. (<a href="http://b.android.com/56586">Issue 56586</a>)</li>
+          <li>Fixed a circular dependency in the ndk-build script, for example: If A-&gt;B and
+            B-&gt;B, then B was dropped from build.
+            (<a href="http://b.android.com/56690">Issue 56690</a>)</li>
+        </ul>
+      </dd>
+
+      <dt>Other bug fixes:</dt>
+      <dd>
+        <ul>
+          <li>Fixed the {@code ndk-build} script to enable you to specify a version of Clang as a
+            command line option (e.g., {@code NDK_TOOLCHAIN_VERSION=clang3.2}). Previously, only
+            specifying the version as an environment variable worked.</li>
+          <li>Fixed gabi++ size of {@code _Unwind_Exception} to be 24 for MIPS build targets when
+            using the Clang compiler.
+            (<a href="https://android-review.googlesource.com/#/c/54141">Change 54141</a>)</li>
+          <li>Fixed the {@code ndk-build} script to ensure that built libraries are actually
+            removed from projects that include prebuilt static libraries when using the
+            {@code ndk-build clean} command.
+            (<a href="https://android-review.googlesource.com/#/c/54461">Change 54461</a>,

+          <li>Modified the {@code NDK_ANALYZE=1} option to be less verbose.</li>
+          <li>Fixed {@code gnu-libstdc++/Android.mk} to include a {@code backward/} path for builds
+            that use backward compability.
+            (<a href="http://b.android.com/53404">Issue 53404</a>)</li>
+          <li>Fixed a problem where {@code stlport new} sometimes returned random values.</li>
+          <li>Fixed {@code ndk-gdb} to match the order of {@code CPU_ABIS}, not {@code APP_ABIS}.
+            (<a href="http://b.android.com/54033">Issue 54033</a>)</li>
+          <li>Fixed a problem where the NDK 64-bit build on MacOSX choses the wrong path for
+            compiler.
+            (<a href="http://b.android.com/53769">Issue 53769</a>)</li>
+          <li>Fixed build scripts to detect 64-bit Windows Vista.
+            (<a href="http://b.android.com/54485">Issue 54485</a>)</li>
+          <li>Fixed x86 {@code ntonl/swap32} error: {@code invalid 'asm': operand number
+            out of range}.
+            (<a href="http://b.android.com/54465">Issue 54465</a>,
+             <a href="https://android-review.googlesource.com/#/c/57242">Change 57242</a>)</li>
+          <li>Fixed {@code ld.gold} to merge string literals.</li>
+          <li>Fixed {@code ld.gold} to handle large symbol alignment.</li>
+          <li>Updated {@code ld.gold} to enable the {@code --sort-section=name} option.</li>
+          <li>Fixed GCC 4.4.3/4.6/4.7 to suppress the {@code -export-dynamic} option for
+            statically linked programs. GCC no longer adds an {@code .interp} section for statically
+            linked programs.</li>
+          <li>Fixed GCC 4.4.3 {@code stlport} compilation error about inconsistent {@code typedef}
+            of {@code _Unwind_Control_Block}.
+            (<a href="http://b.android.com/54426">Issue 54426</a>)</li>
+          <li>Fixed {@code awk} scripts to handle {@code AndroidManifest.xml} files created on
+            Windows which may contain trailing {@code \r} characters and cause build errors.
+            (<a href="http://b.android.com/42548">Issue 42548</a>)</li>
+          <li>Fixed {@code make-standalone-toolchain.sh} to probe the {@code prebuilts/}
+            directory to detect if the host is 32 bit or 64 bit.</li>
+          <li>Fixed the Clang 3.2 {@code -integrated-as} option.</li>
+          <li>Fixed the Clang 3.2 ARM EHABI compact model {@code pr1} and {@code pr2} handler data.
+            </li>
+          <li>Added Clang {@code -mllvm -arm-enable-ehabi} option to fix the following Clang error:
+            <pre>clang: for the -arm-enable-ehabi option: may only occur zero or one times!</pre>
+            </li>
+          <li>Fixed build failure when there is no {@code uses-sdk} element in application
+            manifest. (<a href="http://b.android.com/57015">Issue 57015</a>)</li>

+      <dt>Other changes:</dt>
+      <dd>
+        <ul>
+          <li>Header Fixes
+            <ul>
+              <li>Modified headers to make {@code __set_errno} an inlined function, since
+                {@code __set_errno} in {@code errno.h} is deprecated, and {@code libc.so} no longer
+                exports it.</li>
+              <li>Modified {@code elf.h} to include {@code stdint.h}.
+                (<a href="http://b.android.com/55443">Issue 55443</a>)</li>
+              <li>Fixed {@code sys/un.h} to be included independently of other headers.
+                (<a href="http://b.android.com/53646">Issue 53646</a>)</li>
+              <li>Fixed all of the {@code MotionEvent_getHistorical} API family to take the
+                {@code const AInputEvent* motion_event}.
+                (<a href="http://b.android.com/55873">Issue 55873</a>)</li>
+              <li>Fixed {@code malloc_usable_size} to take {@code const void*}.
+                (<a href="http://b.android.com/55725">Issue 55725</a>)</li>
+              <li>Fixed stdint.h to be more compatible with C99.
+                (<a href="https://android-review.googlesource.com/#/c/46821">Change 46821</a>)</li>
+              <li>Modified {@code wchar.h} to not redefine {@code WCHAR_MAX} and
+                {@code WCHAR_MIN}</li>
+              <li>Fixed {@code &lt;inttypes.h&gt;} declaration for pointer-related {@code PRI} and
+                {@code SCN} macros. (<a href="http://b.android.com/57218">Issue 57218</a>)</li>
+              <li>Changed the {@code sys/cdefs.h} header so that {@code __WCHAR_TYPE__} is 32-bit
+                for API levels less than 9, which means that {@code wchat_t} is 32-bit for all
+                API levels. To restore the previous behavior, define the {@code _WCHAR_IS_8BIT}
+                boolean variable. (<a href="http://b.android.com/57267">Issue 57267</a>)</li>
+            </ul>
+          </li>
+          <li>Added more formatting in NDK {@code docs/} and miscellaneous documentation fixes.
+            </li>
+          <li>Added support for a thin archive technique when building static libraries.
+            (<a href="http://b.android.com/40303">Issue 40303</a>)</li>
+          <li>Updated script {@code make-standalone-toolchain.sh} to support the {@code stlport}
+            library in addition to {@code gnustl}, when you specify the option
+            {@code --stl=stlport}. For more information, see {@code STANDALONE-TOOLCHAIN.html}.</li>
+          <li>Updated the {@code make-standalone-toolchain.sh} script so that the
+            {@code --llvm-version=} option creates the {@code $TOOLCHAIN_PREFIX-clang} and
+            {@code $TOOLCHAIN_PREFIX-clang++} scripts in addition to {@code clang} and
+            {@code clang++}, to avoid using the host's clang and clang++ definitions by accident.
+            </li>
+          <li>Added two flags to re-enable two optimizations in upstream Clang but disabled in
+              NDK for better compatibility with code compiled by GCC:
+            <ul>
+              <li>Added a {@code -fcxx-missing-return-semantics} flag to re-enable <em>missing
+return
+                semantics</em> in Clang 3.2+. Normally, all paths should terminate with a return
+                statement for a value-returning function. If this is not the case, clang inserts
+                an undefined instruction (or trap in debug mode) at the path without a return
+                statement. If you are sure your code is correct, use this flag to allow the
+                optimizer to take advantage of the undefined behavior. If you are not sure, do not
+                use this flag. The caller may still receive a random incorrect value, but the
+                optimizer will not exploit it and make your code harder to debug.</li>
+              <li>Added a {@code -fglobal-ctor-const-promotion} flag to re-enable
+                promoting global variables with static constructor to be constants. With this flag,
+                the global variable optimization pass of LLVM tries to evaluate the global
+                variables with static constructors and promote them to global constants. Although
+                this optimization is correct, it may cause some incompatability with code compiled
+                by GCC. For example, code may do {@code const_cast} to cast the constant to mutable
+                and modify it. In GCC, the variable is in read-write and the code is run by
+                accident. In Clang, the const variable is in read-only memory and may cause your
+                application to crash.</li>
+            </ul>
+          </li>
+          <li>Added {@code -mldc1-sdc1} to the MIPS GCC and Clang compilers. By default, compilers
+            align 8-byte objects properly and emit the {@code ldc1} and {@code sdc1} instructions
+            to move them around. If your app uses a custom allocator that does not always align
+            with a new object's 8-byte boundary in the same way as the default allocator, your app
+            may crash due to {@code ldc1} and {@code sdc1} operations on unaligned memory. In this
+            case, use the {@code -mno-ldc1-sdc1} flag to workaround the problem.</li>
+          <li>Downgraded the event severity from warning to info if {@code APP_PLATFORM_LEVEL} is
+            larger than {@code APP_MIN_PLATFORM_LEVEL}. The {@code APP_PLATFORM_LEVEL} may be lower
+            than {@code APP_PLATFORM} in {@code jni/Application.mk} because the NDK does not have
+            headers for all levels. In this case, the actual level is shifted downwards. The
+            {@code APP_MIN_PLATFORM_LEVEL} is specified by the {@code android:minSdkVersion} in
+            your application's manifest.
+            (<a href="http://b.android.com/39752">Issue 39752</a>)</li>
+          <li>Added the {@code android_getCpuIdArm()} and {@code android_setCpuArm()} methods to
+            {@code cpu-features.c}. This addition enables easier retrieval of the ARM CPUID
+            information. (<a href="http://b.android.com/53689">Issue 53689</a>)</li>
+          <li>Modified {@code ndk-build} to use GCC 4.7's {@code as/ld} for Clang compiling.
+            <p class="note"><strong>Note:</strong>
+              In GCC 4.7, {@code monotonic_clock} and {@code is_monotonic} have been renamed to
+              {@code steady_clock} and {@code is_steady}, respectively.</p></li>
+          <li>Added the following new warnings to the {@code ndk-build} script:
+            <ul>
+              <li>Added warnings if {@code LOCAL_LDLIBS/LDFLAGS} are used in static library
+                modules.</li>
+              <li>Added a warning if a configuration has no module to build.</li>
+              <li>Added a warning for non-system libraries being used in
+                {@code LOCAL_LDLIBS/LDFLAGS} of a shared library or executable modules.</li>
+            </ul>
+          </li>
+          <li>Updated build scripts, so that if {@code APP_MODULES} is not defined and only static
+            libraries are listed in {@code Android.mk}, the script force-builds all of them.
+            (<a href="http://b.android.com/53502">Issue 53502</a>)</li>

+        <ul>
+          <li>Added the GNU Compiler Collection (GCC) 4.7 compiler to the NDK. The GCC 4.6 compiler
+            is still the default, so you must to explicitly enable the new version as follows:
+            <ul>
+              <li>For {@code ndk-build}, export the {@code NDK_TOOLCHAIN_VERSION=4.7} variable
+                <em>or</em> add it to {@code Application.mk}.</li>
+              <li>For standalone builds, add the {@code --toolchain=} option to
+                {@code make-standalone-toolchain.sh}, for example:
+                <pre>--toolchain=arm-linux-androideabi-4.7</pre></li>

+              <a href="http://code.google.com/p/android/issues/list">report any issues</a>.</p>
+          </li>
+          <li>Added {@code stlport} exception support via gabi++.  Note that the new gabi++
+            depends on {@code dlopen} and related code, meaning that:
+            <ul>
+              <li>You can no longer build a <em>static</em> executable using the {@code -static}
+                option or include {@code libstlport_static.a} using
+                {@code APP_STL := stlport_static}. (You can still use the {@code -static} option
+                with a standalone toolchain.) Compiling a <em>dynamic</em> executable using

+        <ul>
+          <li>Added the Clang 3.1 compiler to the NDK. The GNU Compiler Collection (GCC) 4.6 is
+          still the default, so you must explicitly enable the Clang compiler option as follows:
+            <ul>
+              <li>For {@code ndk-build}, export {@code NDK_TOOLCHAIN_VERSION=clang3.1} <em>or</em>
+                add this environment variable setting to {@code Application.mk}.</li>
+              <li>For standalone builds, add {@code --llvm-version=3.1} to
+                {@code make-standalone-toolchain.sh} and replace {@code CC} and {@code CXX} in your
+                makefile with {@code &lt;tool-path&gt;/bin/clang} and
+                {@code &lt;tool-path&gt;/bin/clang++}. See {@code STANDALONE-TOOLCHAIN.html} for
+                details.</li>

+            <a href="http://code.google.com/p/android/issues/list">report any issues</a>.</p></li>
+          <li>Added Gold linker {@code ld.gold} for the Windows toolchain. Gold linker is also the
+            default for ARM and X86 on all hosts. You may override it to use the {@code ld.bfd}
+            linker by adding {@code LOCAL_LDFLAGS += -fuse-ld=bfd} to {@code Android.mk}, or by
+passing
+            {@code -fuse-ld=bfd} to the g++/clang++ command line that does the linking.</li>
+          <li>Added checks for spaces in the NDK path to the {@code ndk-build[.cmd]} and
+            {@code ndk-gdb} scripts, to prevent build errors that are difficult to diagnose.</li>
+          <li>Made the following changes to API level handling:
+            <ul>
+              <li>Modified build logic so that projects that specify {@code android-10} through
+                {@code android-13} in {@code APP_PLATFORM}, {@code project.properties} or
+                {@code default.properties} link against {@code android-9} instead of
+                {@code android-14}.
+              <li>Updated build so that executables using android-16 (Jelly Bean) or higher are
+                compiled with the {@code -fPIE} option for position-independent executables (PIE).
+                A new {@code APP_PIE} option allows you to control this behavior. See {@code
+                APPLICATION-MK.html} for details.
+                <p class="note">
+                  <strong>Note:</strong> All API levels above 14 still link against {@code
+                  platforms/android-14} and no new {@code platforms/android-N} have been added.
+                </p></li>
+              <li>Modified {@code ndk-build} to provide warnings if the adjusted API level is larger
+              than {@code android:minSdkVersion} in the project's {@code AndroidManifest.xml}.</li>
+            </ul>
+          </li>
+          <li>Updated the {@code cpu-features} helper library to include more ARM-specific features.
+          See {@code sources/android/cpufeatures/cpu-features.h} for details.</li>
+          <li>Modified the long double on the X86 platform to be 8 bytes. This data type is now the
+          same size as a double, but is still treated as a distinct type.</li>
+          <li>Updated build for {@code APP_ABI=armeabi-v7a}:
+            <ul>
+              <li>Modified this build type to pass the {@code -march=armv7-a} parameter
+              to the linker. This change ensures that v7-specific libraries and {@code crt*.o} are
+              linked correctly.</li>
+              <li>Added {@code -mfpu=vfpv3-d16} to {@code ndk-build} instead of the
+              {@code -mfpu=vfp} option used in previous releases.</li>
+            </ul>

+            </ul>
+          </li>
+          <li>Removed redundant {@code \r} from Windows prebuilt {@code echo.exe}. The redundant
+          {@code \r} caused {@code gdb.setup} to fail in the GNU Debugger (GDB) because it
+          incorrectly became part of the path.
+          (<a href="http://b.android.com/36054">Issue 36054</a>)</li>

+          <li>Fixed GCC 4.4.3 GNU {@code libstdc++} to <em>not</em> merge {@code typeinfo} names by

+          {@code null} and dereferenced in {@code TREE_CODE}.</li>
+          <li>Fixed GCC 4.4.3 crashes on ARM NEON-specific type definitions for floats.
+          (<a href="http://b.android.com/34613">Issue 34613</a>)</li>
+          <li>Fixed the {@code STLport} internal {@code _IteWrapper::operator*()} implementation
+          where a stale stack location holding the dereferenced value was returned and caused
+          runtime crashes.
+          (<a href="http://b.android.com/38630">Issue 38630</a>)</li>
+
+          <li>ARM-specific fixes:
+            <ul>
+              <li>Fixed ARM GCC 4.4.3/4.6 {@code g++} to not warn that the <em>mangling of
+              &lt;va_list&gt; was changed in GCC 4.4</em>. The workaround using the
+              {@code -Wno-psabi} switch to avoid this warning is no longer required.</li>
+              <li>Fixed an issue when a project with {@code .arm} or {@code .neon} suffixes in
+              {@code LOCAL_SRC_FILES} also used {@code APP_STL}. With {@code APP_STL}, the
+              {@code ndk-build} script searches for C++ files in {@code LOCAL_SRC_FILES} before
+              adding STL {@code header/lib} paths to compilation. Modified {@code ndk-build} to
+              filter out {@code .arm} and {@code .neon} suffixes before the search, otherwise items
+              in {@code LOCAL_SRC_FILES} like {@code myfile.cpp.arm.neon} won't be compiled as C++
+              code.</li>
+              <li>Fixed {@code binutils-2.21/ld.bfd} to be capable of linking object from older
+              binutils without {@code tag_FP_arch}, which was producing <em>assertion fail</em>
+              error messages in GNU Binutils.
+              (<a href="http://b.android.com/35209">Issue 35209</a>)
+              </li>
+              <li>Removed <em>Unknown EABI object attribute 44</em> warning when
+              {@code binutils-2.19/ld} links prebuilt object by newer {@code binutils-2.21}</li>
+              <li>Fixed an issue in GNU {@code stdc++} compilation with both {@code -mthumb} and
+              {@code -march=armv7-a}, by modifying {@code make-standalone-toolchain.sh} to populate
+              {@code headers/libs} in sub-directory {@code armv7-a/thumb}.

+          <li>Updated {@code ndk-gdb} so that it only takes the last line of output for
+          {@code ndk-build} {@code DUMP_XXXX}. This change ensures that if {@code Application.mk} or

+        <ul>
+          <li>Added support for the MIPS ABI, which allows you to generate machine code that runs on
+            compatible MIPS-based Android devices. Major features for MIPS include MIPS-specific
+            toolchains, system headers, libraries and debugging support. For more details regarding
+            MIPS support, see {@code docs/CPU-MIPS.html} in the NDK package.
+
+              <p>By default, code is generated for ARM-based devices. You can add {@code mips} to
+              your {@code APP_ABI} definition in your {@code Application.mk} file to build
+              for MIPS platforms. For example, the following line instructs {@code ndk-build}
+              to build your code for three distinct ABIs:</p>
+
+              <pre>APP_ABI := armeabi armeabi-v7a <strong>mips</strong></pre>
+
+              <p>Unless you rely on architecture-specific assembly sources, such as ARM assembly
+              code, you should not need to touch your {@code Android.mk} files to build MIPS
+              machine code.</p>
+          </li>
+
+          <li>You can build a standalone MIPS toolchain using the {@code --arch=mips}
+          option when calling <code>make-standalone-toolchain.sh</code>. See
+          {@code docs/STANDALONE-TOOLCHAIN.html} for more details.
+          </li>
+        </ul>
+
+        <p class="note"><strong>Note:</strong> To ensure that your applications are available
+to users only if their devices are capable of running them, Google Play filters applications based
+on the instruction set information included in your application ? no action is needed on your part
+to enable the filtering. Additionally, the Android system itself also checks your application at
+install time and allows the installation to continue only if the application provides a library that
+is compiled for the device's CPU architecture.</p>

+            on some multi-core ARM-based devices. Rebuild your unmodified sources with this
+            version of the NDK and this problem should be completely eliminated.
+            For more details, read {@code docs/ANDROID-ATOMICS.html}.</li>
+          <li>Reverted to {@code binutils} 2.19 to fix debugging issues that
+            appeared in NDK r7 (which switched to {@code binutils} 2.20.1).</li>
+          <li>Fixed {@code ndk-build} on 32-bit Linux. A packaging error put a 64-bit version
+            of the {@code awk} executable under {@code prebuilt/linux-x86/bin} in NDK r7.</li>
+          <li>Fixed native Windows build ({@code ndk-build.cmd}). Other build modes were not
+            affected. The fixes include:
+            <ul>
+              <li>Removed an infinite loop / stack overflow bug that happened when trying
+                to call {@code ndk-build.cmd} from a directory that was <em>not</em> the top of
+                your project path (e.g., in any sub-directory of it).</li>
+              <li>Fixed a problem where the auto-generated dependency files were ignored. This
+                meant that updating a header didn't trigger recompilation of sources that included
+                it.</li>
+              <li>Fixed a problem where special characters in files or paths, other than spaces and
+                quotes, were not correctly handled.</li>
+            </ul>
+          </li>
+          <li>Fixed the standalone toolchain to generate proper binaries when using
+            {@code -lstdc++} (i.e., linking against the GNU {@code libstdc++} C++ runtime). You
+            should use {@code -lgnustl_shared} if you want to link against the shared library
+            version or {@code -lstdc++} for the static version.
+

+            {@code libsupc++.a} even though the file was at the right location.</li>
+          <li>Fixed Cygwin C++ link when not using any specific C++ runtime through

+      <dd>
+        <ul>
+          <li>When your application uses the GNU {@code libstdc++} runtime, the compiler will
+            no longer forcibly enable exceptions and RTTI. This change results in smaller code.
+            <p>If you need these features, you must do one of the following:</p>
+            <ul>
+              <li>Enable exceptions and/or RTTI explicitly in your modules or
+                {@code Application.mk}. (recommended)</li>
+              <li>Define {@code APP_GNUSTL_FORCE_CPP_FEATURES} to {@code 'exceptions'},
+                {@code 'rtti'} or both in your {@code Application.mk}. See
+                {@code docs/APPLICATION-MK.html} for more details.</li>
+            </ul>
+          </li>
+          <li>{@code ndk-gdb} now works properly when your application has private services
+            running in independent processes. It debugs the main application process, instead of the
+            first process listed by {@code ps}, which is usually a service process.</li>
+          <li>Fixed a rare bug where NDK r7 would fail to honor the {@code LOCAL_ARM_MODE} value
+            and always compile certain source files (but not all) to 32-bit instructions.</li>
+          <li>{@code STLport}: Refresh the sources to match the Android platform version. This
+            update fixes a few minor bugs:
+            <ul>
+               <li>Fixed instantiation of an incomplete type</li>
+               <li>Fixed minor "==" versus "=" typo</li>
+               <li>Used {@code memmove} instead of {@code memcpy} in {@code string::assign}</li>
+               <li>Added better handling of {@code IsNANorINF}, {@code IsINF}, {@code IsNegNAN},
+                 etc.</li>
+             </ul>
+             <p>For complete details, see the commit log.</p>
+          </li>
+          <li>{@code STLport}: Removed 5 unnecessary static initializers from the library.</li>
+          <li>The GNU libstdc++ libraries for armeabi-v7a were mistakenly compiled for
+            armeabi instead. This change had no impact on correctness, but using the right
+            ABI should provide slightly better performance.</li>
+          <li>The {@code cpu-features} helper library was updated to report three optional
+            x86 CPU features ({@code SSSE3}, {@code MOVBE} and {@code POPCNT}). See
+            {@code docs/CPU-FEATURES.html} for more details.</li>
+          <li>{@code docs/NDK-BUILD.html} was updated to mention {@code NDK_APPLICATION_MK} instead
+            of {@code NDK_APP_APPLICATION_MK} to select a custom {@code Application.mk} file.</li>
+          <li>Cygwin: {@code ndk-build} no longer creates an empty "NUL" file in the current
+            directory when invoked.</li>
+          <li>Cygwin: Added better automatic dependency detection. In the previous version, it
+            didn't work properly in the following cases:
+            <ul>
+              <li>When the Cygwin drive prefix was not {@code /cygdrive}.</li>
+              <li>When using drive-less mounts, for example, when Cygwin would translate
+                {@code /home} to {@code \\server\subdir} instead of {@code C:\Some\Dir}.</li>
+            </ul>
+          </li>
+          <li>Cygwin: {@code ndk-build} does not try to use the native Windows tools under
+            {@code $NDK/prebuilt/windows/bin} with certain versions of Cygwin and/or GNU Make.</li>

+    <p>This release of the NDK includes new features to support the Android 4.0 platform as well
+    as many other additions and improvements:</p>
+
+    <dl>
+      <dt>New features</dt>
+
+      <dd>
+        <ul>
+          <li>Added official NDK APIs for Android 4.0 (API level 14), which adds the following
+          native features to the platform:
+
+            <ul>
+              <li>Added native multimedia API based on the Khronos Group OpenMAX AL? 1.0.1
+              standard. The new <code>&lt;OMXAL/OpenMAXAL.h&gt;</code> and
+              <code>&lt;OMXAL/OpenMAXAL_Android.h&gt;</code> headers allow applications targeting
+              API level 14 to perform multimedia output directly from native code by using a new
+              Android-specific buffer queue interface. For more details, see
+              <code>docs/openmaxal/index.html</code> and <a href=
+              "http://www.khronos.org/openmax/">http://www.khronos.org/openmax/</a>.</li>
+
+              <li>Updated the native audio API based on the Khronos Group OpenSL ES 1.0.1?
+              standard. With API Level 14, you can now decode compressed audio (e.g. MP3, AAC,
+              Vorbis) to PCM. For more details, see <code>docs/opensles/index.html</code> and
+              <a href=
+              "http://www.khronos.org/opensles">http://www.khronos.org/opensles/</a>.</li>
+            </ul>
+          </li>
+
+          <li>Added CCache support. To speed up large rebuilds, define the
+          <code>NDK_CCACHE</code> environment variable to <code>ccache</code> (or the path to
+          your <code>ccache</code> binary). When declared, the NDK build system automatically
+          uses CCache when compiling any source file. For example:
+            <pre>
+export NDK_CCACHE=ccache
+</pre>
+          <p class="note"><strong>Note:</strong> CCache is not included in the NDK release
+          so you must have it installed prior to using it. For more information about CCache, see
+          <a href="http://ccache.samba.org">http://ccache.samba.org</a>.</p>
+          </li>
+
+          <li>Added support for setting <code>APP_ABI</code> to <code>all</code> to indicate that
+          you want to build your NDK modules for all the ABIs supported by your given NDK
+          release. This means that either one of the following two lines in your
+          <code>Application.mk</code> are equivalent with this release:
+            <pre>
+APP_ABI := all
+APP_ABI := armeabi armeabi-v7a x86
+</pre>
+
+            <p>This also works if you define <code>APP_ABI</code> when calling
+            <code>ndk-build</code> from the command-line, which is a quick way to check that your
+            project builds for all supported ABIs without changing the project's
+            <code>Application.mk file</code>. For example:</p>
+            <pre>
+ndk-build APP_ABI=all
+</pre>
+          </li>
+
+          <li>Added a <code>LOCAL_CPP_FEATURES</code> variable in <code>Android.mk</code> that
+          allows you to declare which C++ features (RTTI or Exceptions) your module uses. This
+          ensures that the final linking works correctly if you have prebuilt modules that depend
+          on these features. See <code>docs/ANDROID-MK.html</code> and
+          <code>docs/CPLUSPLUS-SUPPORT.html</code> for more details.</li>
+
+          <li>Shortened paths to source and object files that are used in build commands. When
+          invoking <code>$NDK/ndk-build</code> from your project path, the paths to the source,
+          object, and binary files that are passed to the build commands are significantly
+          shorter now, because they are passed relative to the current directory. This is useful
+          when building projects with a lot of source files, to avoid limits on the maximum
+          command line length supported by your host operating system. The behavior is unchanged
+          if you invoke <code>ndk-build</code> from a sub-directory of your project tree, or if
+          you define <code>NDK_PROJECT_PATH</code> to point to a specific directory.</li>
+        </ul>
+      </dd>
+
+      <dt>Experimental features</dt>
+
+      <dd>
+        You can now build your NDK source files on Windows <em>without</em> Cygwin by calling the
+        <code>ndk-build.cmd</code> script from the command line from your project path. The
+        script takes exactly the same arguments as the original <code>ndk-build</code> script.
+        The Windows NDK package comes with its own prebuilt binaries for GNU Make, Awk and other
+        tools required by the build. You should not need to install anything else to get a
+        working build system.
+
+        <p class="caution"><strong>Important:</strong> <code>ndk-gdb</code> does not work on
+        Windows, so you still need Cygwin to debug.</p>
+
+        <p>This feature is still experimental, so feel free to try it and report issues on the
+        <a href="http://b.android.com">public bug database</a> or <a href=
+        "http://groups.google.com/group/android-ndk">public forum</a>. All samples and unit tests
+        shipped with the NDK succesfully compile with this feature.</p>

+          location (<code>libs/&lt;abi&gt;</code>) if <code>APP_MODULES</code> is not defined in
+          your <code>Application.mk</code>. For example, if a top-level module <code>foo</code>
+          imports a module <code>bar</code>, then both <code>libfoo.so</code> and
+          <code>libbar.so</code> are copied to the install location. Previously, only
+          <code>libfoo.so</code> was copied, unless you listed <code>bar</code> in your
+          <code>APP_MODULES</code> too. If you define <code>APP_MODULES</code> explicitly, the

+          their MAIN intent filters.</li>
+
+          <li>Static library imports are now properly transitive. For example, if a top-level
+          module <code>foo</code> imports static library <code>bar</code> that imports static
+          library <code>zoo</code>, the <code>libfoo.so</code> will now be linked against both

+
+          <li><code>docs/STABLE-APIS.html</code>: Added missing documentation listing EGL as a
+          supported stable API, starting from API level 9.</li>
+

+          which is the new location for the AOSP servers.</li>
+

+          are available in the updated <code>docs/CPLUSPLUS-SUPPORT.html</code>.</li>

+          <li>Added a new C++ support runtime named <code>gnustl_shared</code> that corresponds
+          to the shared library version of GNU libstdc++ v3 (GPLv3 license). See more info at
+          <code>docs/CPLUSPLUS-SUPPORT.html</code></li>
+
+          <li>Added support for RTTI in the STLport C++ runtimes (no support for
+          exceptions).</li>
+
+          <li>Added support for multiple file extensions in <code>LOCAL_CPP_EXTENSION</code>. For
+          example, to compile both <code>foo.cpp</code> and <code>bar.cxx</code> as C++ sources,
+          declare the following:
+            <pre>
+LOCAL_CPP_EXTENSION := .cpp .cxx
+</pre>
+          </li>
+
+          <li>Removed many unwanted exported symbols from the link-time shared system libraries
+          provided by the NDK. This ensures that code generated with the standalone toolchain
+          doesn't risk to accidentally depend on a non-stable ABI symbol (e.g. any libgcc.a
+          symbol that changes each time the toolchain used to build the platform is changed)</li>
+
+          <li>Refreshed the EGL and OpenGLES Khronos headers to support more extensions. Note
+          that this does <em>not</em> change the NDK ABIs for the corresponding libraries,
+          because each extension must be probed at runtime by the client application.
+
+            <p>The extensions that are available depend on your actual device and GPU drivers,
+            not the platform version the device runs on. The header changes simply add new
+            constants and types to make it easier to use the extensions when they have been
+            probed with <code>eglGetProcAddress()</code> or <code>glGetProcAddress()</code>. The
+            following list describes the newly supported extensions:</p>

+      <p>This release of the NDK includes support for the x86 ABI and other minor changes.
+      For detailed information describing the changes in this release, read the
+      <code>CHANGES.HTML</code> document included in the NDK package.
+      </p>
+      <dl>
+        <dt>General notes:</dt>
+        <dd>
+          <ul>
+            <li>Adds support for the x86 ABI, which allows you to generate machine code
+            that runs on compatible x86-based Android devices. Major features for x86
+            include x86-specific toolchains, system headers, libraries and
+            debugging support. For all of the details regarding x86 support,
+            see <code>docs/CPU-X86.html</code> in the NDK package.
+
+              <p>By default, code is generated for ARM-based devices, but you can add x86 to your
+              <code>APP_ABI</code> definition in your <code>Application.mk</code> file to build
+              for x86 platforms. For example, the following line instructs <code>ndk-build</code>
+              to build your code for three distinct ABIs:</p>
+
+              <pre>APP_ABI := armeabi armeabi-v7a x86</pre>
+
+              <p>Unless you rely on ARM-based assembly sources, you shouldn't need to touch
+              your <code>Android.mk</code> files to build x86 machine code.</p>
+
+            </li>
+
+            <li>You can build a standalone x86 toolchain using the
+<code>--toolchain=x86-4.4.3</code>
+            option when calling <code>make-standalone-toolchain.sh</code>. See
+            <code>docs/STANDALONE-TOOLCHAIN.html</code> for more details.
+            </li>
+            <li>The new <code>ndk-stack</code> tool lets you translate stack traces in
+            <code>logcat</code> that are generated by native code. The tool translates
+            instruction addresses into a readable format that contains things such
+            as the function, source file, and line number corresponding to each stack frame.
+            For more information and a usage example, see <code>docs/NDK-STACK.html</code>.

+      <dd>
+        <ul>
+          <li><code>ndk-build</code>: Fixed a rare bug that appeared when trying to perform parallel
+          builds of debuggable projects.</li>
+
+          <li>Fixed a typo that prevented <code>LOCAL_WHOLE_STATIC_LIBRARIES</code> to work
+          correctly with the new toolchain and added documentation for this in
+          <code>docs/ANDROID-MK.html</code>.</li>
+
+          <li>Fixed a bug where code linked against <code>gnustl_static</code> crashed when run on
+          platform releases older than API level 8 (Android 2.2).</li>
+
+          <li><code>ndk-gdb</code>: Fixed a bug that caused a segmentation fault when debugging
+Android 3.0
+          or newer devices.</li>
+
+          <li><code>&lt;android/input.h&gt;</code>: Two functions that were introduced in API level
+          9 (Android 2.3) were incorrect and are fixed. While this breaks the source API, the
+          binary interface to the system is unchanged. The incorrect functions were missing a
+          <code>history_index</code> parameter, and the correct definitions are shown below:
+<pre>
+float AMotionEvent_getHistoricalRawX(const AInputEvent* motion_event,

+</pre>
+          </li>
+
+          <li>Updated the C library ARM binary for API level 9 (Android 2.3) to correctly expose at
+          link time new functions that were added in that API level (for example,
+          <code>pthread_rwlock_init</code>).</li>

+          <code>LOCAL_SRC_FILES</code>. This was not the case previously because the files were
+          grouped by source extensions instead.</li>
+
+          <li>When <code>import-module</code> fails, it now prints the list of directories that
+          were searched. This is useful to check that the <code>NDK_MODULE_PATH</code> definition
+          used by the build system is correct.</li>
+
+          <li>When <code>import-module</code> succeeds, it now prints the directory where the
+          module was found to the log (visible with <code>NDK_LOG=1</code>).</li>
+
+          <li>Increased the build speed of debuggable applications when there is a very large number
+          of include directories in the project.</li>
+
+          <li><code>ndk-gdb</code>: Better detection of <code>adb shell</code> failures and improved
+          error messages.</li>
+
+          <li><code>&lt;pthread.h&gt;</code>: Fixed the definition of
+          <code>PTHREAD_RWLOCK_INITIALIZER</code> for API level 9 (Android 2.3) and higher.</li>
+
+          <li>Fixed an issue where a module could import itself, resulting in an infinite loop in
+          GNU Make.</li>
+
+          <li>Fixed a bug that caused the build to fail if <code>LOCAL_ARM_NEON</code> was set to
+          true (typo in <code>build/core/build-binary.mk</code>).</li>
+
+          <li>Fixed a bug that prevented the compilation of <code>.s</code> assembly files

+      <p>This release of the NDK does not include any new features compared to r5. The r5b release
+addresses the
+      following problems in the r5 release:
+      </p>
+      <ul>
+    <li>The r5 binaries required glibc 2.11, but the r5b binaries are generated with a special
+    toolchain that targets glibc 2.7 or higher instead. The Linux toolchain binaries now run on
+Ubuntu 8.04 or higher. </li>
+    <li>Fixes a compiler bug in the arm-linux-androideabi-4.4.3 toolchain.
+    The previous binary generated invalid thumb instruction sequences when
+    dealing with signed chars.</li>
+    <li>Adds missing documentation for the
+    "gnustl_static" value for APP_STL, that allows you to link against
+    a static library version of GNU libstdc++. </li> the
+    <li>Fixed the following <code>ndk-build</code> issues:
+      <ul>
+        <li>A bug that created inconsistent dependency files when a
+        compilation error occured on Windows. This prevented a proper build after
+        the error was fixed in the source code.</li>
+        <li>A Cygwin-specific bug where using very short paths for
+        the Android NDK installation or the project path led to the
+        generation of invalid dependency files. This made incremental builds
+        impossible.</li>
+        <li>A typo that prevented the cpufeatures library from working correctly
+        with the new NDK toolchain.</li>
+        <li>Builds in Cygwin are faster by avoiding calls to <code>cygpath -m</code>
+        from GNU Make for every source or object file, which caused problems
+        with very large source trees. In case this doesn't work properly, define
+<code>NDK_USE_CYGPATH=1</code> in your
+        environment to use <code>cygpath -m</code> again.</li>
+        <li>The Cygwin installation now notifies the user of invalid installation paths that
+contain spaces. Previously, an invalid path
+        would output an error that complained about an incorrect version of GNU Make, even if the
+right one was installed.
+      </ul>
+    </li>
+  <li>Fixed a typo that prevented the <code>NDK_MODULE_PATH</code> environment variable from
+working properly when
+  it contained multiple directories separated with a colon. </li>
+  <li>The <code>prebuilt-common.sh</code> script contains fixes to check the compiler for 64-bit
+  generated machine code, instead of relying on the host tag, which
+  allows the 32-bit toolchain to rebuild properly on Snow Leopard. The toolchain rebuild scripts
+now also support
+  using a 32-bit host toolchain.</li>
+  <li>A missing declaration for <code>INET_ADDRSTRLEN</code> was added to
+<code>&lt;netinet/in.h&gt;</code>.</li>
+  <li>Missing declarations for <code>IN6_IS_ADDR_MC_NODELOCAL</code> and
+<code>IN6_IS_ADDR_MC_GLOBAL</code> were added to <code>&lt;netinet/in6.h&gt;</code>.</li>
+  <li>'asm' was replaced with '__asm__' in <code>&lt;asm/byteorder.h&gt;</code> to allow
+compilation with <code>-std=c99</code>.</li>

+          <ul>
+            <li>Adds support for native activities, which allows you to implement the
+            Android application lifecycle in native code.</li>
+
+            <li>Adds native support for the following:
+
+              <ul>
+
+                <li>Input subsystem (such as the keyboard and touch screen)</li>
+
+                <li>Access to sensor data (accelerometer, compass, gyroscope, etc).</li>
+
+                <li>Event loop APIs to wait for things such as input and sensor events.</li>
+
+                <li>Window and surface subsystem</li>
+
+                <li>Audio APIs based on the OpenSL ES standard that support playback and recording
+                as well as control over platform audio effects</li>
+
+                <li>Access to assets packaged in an <code>.apk</code> file.</li>
+
+              </ul>
+            </li>
+
+            <li>Includes a new toolchain (based on GCC 4.4.3), which generates better code, and can
+also now
+            be used as a standalone cross-compiler, for people who want to build their stuff with
+            <code>./configure &amp;&amp; make</code>. See
+            docs/STANDALONE-TOOLCHAIN.html for the details. The binaries for GCC 4.4.0 are still
+provided,
+            but the 4.2.1 binaries were removed.</li>
+
+            <li>Adds support for prebuilt static and shared libraries (docs/PREBUILTS.html) and
+module
+            exports and imports to make sharing and reuse of third-party modules much easier
+            (docs/IMPORT-MODULE.html explains why).</li>
+
+            <li>Provides a default C++ STL implementation (based on STLport) as a helper module. It
+can be used either
+            as a static or shared library (details and usage examples are in
+sources/android/stlport/README). Prebuilt
+            binaries for STLport (static or shared) and GNU libstdc++ (static only) are also
+provided if you choose to
+            compile against those libraries instead of the default C++ STL implementation.
+            C++ Exceptions and RTTI are not supported in the default STL implementation. For more
+information, see
+            docs/CPLUSPLUS-SUPPORT.HTML.</li>
+
+            <li>Includes improvements to the <code>cpufeatures</code> helper library that improves
+reporting
+            of the CPU type (some devices previously reported ARMv7 CPU when the device really was
+an ARMv6). We
+            recommend developers that use this library to rebuild their applications then
+            upload to Google Play to benefit from the improvements.</li>
+
+            <li>Adds an EGL library that lets you create and manage OpenGL ES textures and
+              services.</li>
+
+            <li>Adds new sample applications, <code>native-plasma</code> and
+<code>native-activity</code>,
+            to demonstrate how to write a native activity.</li>
+
+            <li>Includes many bugfixes and other small improvements; see docs/CHANGES.html for a
+more
+              detailed list of changes.</li>

+          <ul>
+            <li>Provides a simplified build system through the new <code>ndk-build</code> build
+            command.</li>
+
+            <li>Adds support for easy native debugging of generated machine code on production
+            devices through the new <code>ndk-gdb</code> command.</li>
+
+            <li>Adds a new Android-specific ABI for ARM-based CPU architectures,
+            <code>armeabi-v7a</code>. The new ABI extends the existing <code>armeabi</code> ABI to
+            include these CPU instruction set extensions:
+
+              <ul>
+                <li>Thumb-2 instructions</li>
+
+                <li>VFP hardware FPU instructions (VFPv3-D16)</li>
+
+                <li>Optional support for ARM Advanced SIMD (NEON) GCC intrinsics and VFPv3-D32.
+                Supported by devices such as Verizon Droid by Motorola, Google Nexus One, and
+                others.</li>
+              </ul>
+            </li>
+
+            <li>Adds a new <code>cpufeatures</code> static library (with sources) that lets your
+            app detect the host device's CPU features at runtime. Specifically, applications can
+            check for ARMv7-A support, as well as VFPv3-D32 and NEON support, then provide separate
+            code paths as needed.</li>
+
+            <li>Adds a sample application, <code>hello-neon</code>, that illustrates how to use the
+            <code>cpufeatures</code> library to check CPU features and then provide an optimized
+            code path using NEON instrinsics, if supported by the CPU.</li>
+
+            <li>Lets you generate machine code for either or both of the instruction sets supported
+            by the NDK. For example, you can build for both ARMv5 and ARMv7-A architectures at the
+            same time and have everything stored to your application's final
+            <code>.apk</code>.</li>
+
+            <li>To ensure that your applications are available to users only if their devices are
+            capable of running them, Google Play now filters applications based on the
+            instruction set information included in your application &mdash; no action is needed on
+            your part to enable the filtering. Additionally, the Android system itself also checks
+            your application at install time and allows the installation to continue only if the
+            application provides a library that is compiled for the device's CPU architecture.</li>
+
+            <li>Adds support for Android 2.2, including a new stable API for accessing the pixel
+            buffers of {@link android.graphics.Bitmap} objects from native code.</li>

-<p>This section provides the information you need to get up and running

+<p>The Native Development Kit (NDK) is a set of tools that allow you to leverage C and
+C++ code in your Android apps. You can use it either to build from your own source code, or to take
+advantage of existing prebuilt libraries.</p>
+
+<p>The NDK is not appropriate for most novice Android programmers, and has little value for many

-<p>NDK reference docs
\ No newline at end of file
+<p>The API reference for the NDK includes documentation for the base set of
+native headers that the NDK provides for Android. These headers, and their associated libraries,
+expose a variety of features otherwise only accessible via the Android framework.
+A few of these features are as follows:</p>
+
+<ul>
+   <li>Using hardware sensors.</li>
+   <li>Accessing storage.</li>
+   <li>Handling user input.</li>
+   <li>Setting configuration information, such as screen orientation.</li>
+</ul>
+
+<p>The API reference provides detailed information on these and other functionalities provided
+in the NDK.</p>

-
-</div>
-</div>
-
-<p>API Level: M</p>
-<p>Along with new features and capabilities, M includes a variety of
-system changes and API behavior changes. This document highlights
-some of the key changes that you should be understand and account for in your apps.</p>
-
-<p>If you have previously published an app for Android, be aware that your app
-  might be affected by these changes in M.</p>
-
-<h2 id="behavior-runtime-permissions">Runtime Permissions</h1>
-<p>This release introduces a new runtime permissions model, where users can now directly manage
-their app permissions at runtime. This model gives users improved visibility and control over
-permissions, while streamlining the installation and auto-update processes for app developers.
-Users can set permissions on or off for all apps running on Android M. However, apps that don’t
-target M cannot request permissions at runtime.</p>
-
-<p>On your apps that target M, make sure to check and request for permissions at
-runtime. To determine if your app has been granted a permission, call the
-new {@code Context.checkSelfPermission()} method. To request for a permission, call the new
-{@code Activity.requestPermission()} method.</p>
-
-<p>For more information on supporting the new permissions model in your app, see the
-<a href="{@docRoot}preview/features/runtime-permissions.html">
-Android M Runtime Permissions guide</a>.</p>
-
-<h2 id="behavior-openssl">OpenSSL</h2>
-<p>Android is moving away from OpenSSL to the
-<a href="https://boringssl.googlesource.com/boringssl/" class="external-link">BoringSSL</a>
-library. If you’re using the Android NDK in your app, don't link against cryptographic libraries
-that are not a part of the NDK API, such as {@code libcrypto.so} and {@code libssl.so}. These
-libraries are not public APIs, and may change or break without notice across releases and devices.
-In addition, you may expose yourself to security vulnerabilities. Instead, modify your
-native code to call the Java cryptography APIs via JNI or to statically link against a
-cryptography library of your choice.</p>
-
-<h2 id="behavior-project-volta">Project Volta</h2>
-<p>This release introduces new power-saving optimizations for idle devices and apps.</p>
-
-<h3 id="behavior-doze">Doze mode</h3>
-<p>If a device is unplugged and not used for up to an hour, it goes into <em>doze</em> mode where
-it attempts to keep the system in a sleep state. In this mode, devices may briefly resume normal
-operations for up to 5 minutes every few hours so that app syncing can occur and the system can
-perform any pending operations.</p>
-
-<p>The following restrictions apply to your apps while in device doze mode:</p>
-<ul>
-<li>Network access is disabled</li>
-<li>Alarms scheduled with the {@link android.app.AlarmManager} class are disabled, except for
-alarms that you've set with the
-{@link android.app.AlarmManager#setAlarmClock(android.app.AlarmManager.AlarmClockInfo,android.app.PendingIntent) setAlarmClock()}
-method</li>
-<li>WiFi scans are not performed</li>
-<li>Syncs and jobs for your sync adapters and {@link android.app.job.JobScheduler} are not
-permitted to run</li>
-</ul>
-</p>
-<p>When the system comes out of doze mode, it executes jobs and syncs that are pending.</p>
-
-<h3 id="behavior-app-standby">App standby mode</h3>
-<p>In M, the system may determine that apps are idle when they are not in active use by the user.
-Your app goes into <em>app standby</em> mode after two days unless the system detects any of these
-signals:</p>
-
-<ul>
-<li>The app has a process currently in the foreground (either as an activity or foreground service,
-or in use by another activity or foreground service)</li>
-<li>The app generates a notification that the user can see</li>
-<li>The user explicitly asks for the app to remain running</li>
-</ul>
-
-<p>If the system is running on battery power, apps that are in standby mode will have their
-network access disabled and their syncs and jobs suspended. When the system is plugged into a power
-supply, it brings an app out of standby mode and executes any jobs and syncs that are pending.</p>
-
-<p>Apps that use <a href="{@docRoot}google/gcm/index.html">Google Cloud Messaging</a> will
-continue to receive messages even if they are idle. When the system is plugged into a power
-supply, apps resume normal operations and can run any pending syncs and jobs.</p>
-
-<p>You can test this feature by connecting a device running M to your development machine and
-calling the following commands:
-</p>
-<pre>
-$ adb shell am broadcast -a android.os.action.DISCHARGING
-$ adb shell am set-idle &lt;packageName&gt; true
-$ adb shell am set-idle &lt;packageName&gt; false
-$ adb shell am get-idle &lt;packageName&gt;
-</pre>
-
-<h2 id="behavior-adoptable-storage">Adoptable Storage Devices</h2>
-<p>
-In M, users can adopt external storage devices such as SD cards. Adopting an external storage
-device encrypts and formats the device to behave like internal storage. This feature allows users
-to move both apps and private data of those apps between storage devices. When moving apps, the
-system respects the <a href="{@docRoot}guide/topics/manifest/manifest-element.html#install">
-{@code android:installLocation}</a> preference in the manifest.</p>
-
-<p>If your app accesses the following APIs or fields, be aware that the file paths they return
-will dynamically change when the app is moved between internal and external storage devices.
-When building file paths, it is strongly recommended that you always call these APIs dynamically.
-Don’t use hardcoded file paths or persist fully-qualified file paths that were built previously.</p>
-

-        <li>{@link android.content.pm.ApplicationInfo#splitPublicSourceDirs splitPublicSourceDirs}</li>
-    </ul>
-</li>
-</ul>
-
-<p>To debug this feature in the developer preview, you can enable adoption of a USB drive that is
-connected to an Android device through a USB On-The-Go (OTG) cable, by running these
-commands:</p>
-
-<pre>
-$ adb root
-$ sleep 2
-$ adb shell setprop persist.fw.force_adoptable 1
-$ adb reboot
-</pre>
-
-<h2 id="behavior-apache-http-client">Apache HTTP Client Removal</h2>
-<p>This release removes support for the Apache HTTP client. If your app is using this client and
-targets Android 2.3 (API level 9) or higher, use the {@link java.net.HttpURLConnection} class
-instead. This API is more efficient because it reduces network use through transparent compression
-and response caching, and minimizes power consumption. To continue using the Apache HTTP APIs, you
-must first declare the following compile-time dependency in your {@code build.gradle} file:
-</p>
-<pre>
-android {
-    compileSdkVersion M
-    useLibrary 'org.apache.http.legacy'
-}
-</pre>
-
-<h2 id="behavior-audiomanager-Changes">AudioManager Changes</h2>
-<p>Setting the volume directly or muting specific streams via the {@link android.media.AudioManager}
-class is no longer supported. The {@link android.media.AudioManager#setStreamSolo(int,boolean)
-setStreamSolo()} method is deprecated, and you should call the
-{@code AudioManager.requestAudioFocus()} method instead. Similarly, the
-{@link android.media.AudioManager#setStreamMute(int,boolean) setStreamMute()} method is
-deprecated; instead, call the {@code AudioManager.adjustStreamVolume()} method
-and pass in the direction value {@code ADJUST_MUTE} or {@code ADJUST_UNMUTE}.</p>
-
-<h2 id="behavior-test-selection">Text Selection</h2>
-
-<img src="{@docRoot}preview/images/text-selection.gif"
-style="float:right; margin:0 0 20px 30px" width="270" height="480" />
-
-<p>When users selects text in your app, you can now display text selection actions such as
-<em>Cut</em>, <em>Copy</em>, and <em>Paste</em> in a
-<a href="http://www.google.com/design/spec/patterns/selection.html#selection-text-selection"
-class="external-link">floating toolbar</a>. The user interaction implementation is similar to that
-for the contextual action bar, as described in
-<a href="{@docRoot}guide/topics/ui/menus.html#CABforViews">
-Enabling the contextual action mode for individual views</a>.</p>
-
-<p>To implement a floating toolbar for text selection, make the following changes in your existing
-apps:</p>
-<ol>
-<li>In your {@link android.view.View} or {@link android.app.Activity} object, change your
-{@link android.view.ActionMode} calls from
-{@code startActionMode(Callback)} to {@code startActionMode(Callback, ActionMode.TYPE_FLOATING)}.</li>
-<li>Take your existing implementation of ActionMode.Callback and make it extend
-{@code ActionMode.Callback2} instead.</li>
-<li>Override the {@code Callback2.onGetContentRect()} method to provide the coordinates of the
-content {@link android.graphics.Rect} object (such as a text selection rectangle) in the view.</li>
-<li>If the rectangle positioning is no longer valid, and this is the only element to be invalidated,
-call the {@code ActionMode.invalidateContentRect()} method.</li>
-</ol>
-
-<p>If you are using <a href="{@docRoot}tools/support-library/index.html">
-Android Support Library</a> revision 22.2, be aware that floating toolbars are not
-backward-compatible and appcompat takes control over {@link android.view.ActionMode} objects by
-default. This prevents floating toolbars from being displayed in M. To enable
-{@link android.view.ActionMode} support in an
-{@link android.support.v7.app.AppCompatActivity}, call
-{@code android.support.v7.app.AppCompatActivity.getDelegate()}, then call
-{@code android.support.v7.app.AppCompatDelegate.setHandleNativeActionModesEnabled()} on the returned
-{@link android.support.v7.app.AppCompatDelegate} object and set the input
-parameter to {@code false}. This call returns control of {@link android.view.ActionMode} objects to
-the framework. In devices running M, that allows the framework to support
-{@link android.support.v7.app.ActionBar} or floating toolbar modes, while on pre-M devices, only the
-{@link android.support.v7.app.ActionBar} modes are supported.</p>
-
-<h2 id="behavior-keystore">Android Keystore Changes</h2>
-<p>Starting this release, the
-<a href="{@docRoot}training/articles/keystore.html">Android Keystore provider</a> no longer supports
-DSA. ECDSA is still supported.</p>
-
-<p>Keys which do not require encryption at rest will no longer be deleted when secure lock screen
-is disabled or reset (for example, by the user or a Device Administrator). Keys which require
-encryption at rest will be deleted during these events.</p>
-
-<h2 id="behavior-themeable-colorstatelists">Themeable ColorStateLists</h2>
-<p>Theme attributes are now supported in
-{@link android.content.res.ColorStateList} for devices running M. The
-{@link android.content.res.Resources#getColorStateList(int) getColorStateList()} and
-{@link android.content.res.Resources#getColor(int) getColor()} methods have been deprecated. If
-you are calling these APIs, call the new {@code Context.getColorStateList()} or
-{@code Context.getColor()} methods instead. These methods are also available in the
-v4 appcompat library via {@link android.support.v4.content.ContextCompat}.</p>
-
-<h2 id="night-mode">Night Mode (User-configurable Dark Theme)</h2>
-<p>
-Support for the {@code -night} resource qualifier has been updated in M. Previously, night mode was
-only available when a device was docked and in car mode. Starting in M, night mode is available on
-all devices and is user-configurable via <em>Settings > Display > Theme</em>. You can adjust this
-setting globally using {@link android.app.UiModeManager#setNightMode(int) setNightMode()}. The
-Dark theme corresponds to {@link android.app.UiModeManager#MODE_NIGHT_YES}. When the device is in
-night mode, the resource framework will prefer resources that have the -night qualifier. To
-take advantage of user-configurable Dark mode in your app, extend from the
-{@code Theme.Material.DayNight} set of themes rather than {@code Theme.Material} or
-{@code Theme.Material.Light}.
-</p>

-<h2 id="behavior-art-runtime">ART Runtime</h2>
-<p>The ART runtime now properly implements access rules for the
-{@link java.lang.reflect.Constructor#newInstance(java.lang.Object...) newInstance()} method. This
-change fixes a problem where Dalvik was checking access rules incorrectly in previous versions.
-If your app uses the
-{@link java.lang.reflect.Constructor#newInstance(java.lang.Object...) newInstance()} method and you
-want to override access checks, call the
-{@link java.lang.reflect.Constructor#setAccessible(boolean) setAccessible()} method with the input
-parameter set to {@code true}. If your app uses the
-<a href="{@docRoot}tools/support-library/features.html#v7">v7 appcompat library</a> or the
-<a href="{@docRoot}tools/support-library/features.html#v7-recyclerview">v7 recyclerview library</a>,
-you must update your app to use to the latest versions of these libraries. Otherwise, make sure that
-any custom classes referenced from XML are updated so that their class constructors are accessible.</p>
-
-<p>The M release updates the behavior of the dynamic linker. The dynamic linker now understands the
-difference between a library’s {@code soname} and its path
-(<a href="https://code.google.com/p/android/issues/detail?id=6670" class="external-link">
-public bug 6670</a>), and search by {@code soname} is now
-implemented. Apps which previously worked that have bad {@code DT_NEEDED} entries
-(usually absolute paths on the build machine’s file system) may fail when loaded on M.</p>
-
-<p>The {@code dlopen(3) RTLD_LOCAL} flag is now correctly implemented in M. Note that
-{@code RTLD_LOCAL} is the default, so calls to {@code dlopen(3)} that didn’t explicitly use
-{@code RTLD_LOCAL} will be affected (unless your app explicitly used {@code RTLD_GLOBAL}). With
-{@code RTLD_LOCAL}, symbols will not be made available to libraries loaded by later calls to
-{@code dlopen(3)} (as opposed to being referenced by {@code DT_NEEDED} entries).</p>

-<h2 id="behavior-afw">Android for Work Changes</h2>
-<p>This release includes the following behavior changes for Android for Work:</p>
-<ul>
-<li><strong>Work contacts in personal contexts.</strong> Google Messenger and the Google Dialer
-Call Log now display work contacts when the user views past messages or calls. Furthermore, both
-work and personal contacts are now available to devices over Bluetooth, but you can hide work
-profile contacts through a device policy by calling the new
-{@code DevicePolicyManager.setBluetoothContactSharingDisabled()} method. Initiating a call or
-creating a new message will only show personal contacts, as consistent with the experience in
-Android 5.0.
-</li>
-<li><strong>WiFi configuration removal:</strong> WiFi configurations added by a Profile Owner
-(for example, through calls to the
-{@link android.net.wifi.WifiManager#addNetwork(android.net.wifi.WifiConfiguration)
-addNetwork()} method) are now removed if that work profile is deleted.</li>
-<li><strong>WiFi configuration lockdown:</strong> Any WiFi configuration created by an active Device
-Owner can no longer be modified or deleted by the user. The user can still create and
-modify their own WiFi configurations, so long as the {@link android.os.UserManager} constant
-{@link android.os.UserManager#DISALLOW_CONFIG_WIFI} has not been set for that user.</li>
-<li><strong>VPN in Settings:</strong> VPN apps are now visible in <em>Settings > More > VPN</em>.
-Additionally, the notifications that accompany VPN usage are now specific to whether that VPN is
-configured for a managed profile or the entire device.</li>
-<li><strong>Work status notification:</strong> A status bar briefcase icon now appears whenever
-an app from the managed profile has an activity in the foreground. Furthermore, if the device is
-unlocked directly to the activity of an app in the managed profile, a toast is displayed notifying
-the user that they are within the work profile.
-</li>
-<li><strong>Download Work Policy Controller via Google account addition:</strong> When a Google
-account that requires management via a Work Policy Controller (WPC) app is added to a device
-outside of a managed context, the add account flow now prompts the user to install the
-appropriate WPC. This behavior also applies to accounts added via
-<em>Settings > Accounts</em> in the initial device setup wizard.</li>

-<h2 id="data_binding_layout_files">Data Binding Layout Files</h2>
-
-
-<h3 id="writing_expressions">Writing your first data binding expressions:</h3>
-
-<p>Data-binding layout files are slightly different and start with a root tag of
-<strong>layout</strong> followed by a <strong>data</strong> element and a
-<strong>view</strong> root element. This view element is what your root would
-be in a non-binding layout file.A sample file looks like this:</p>
-
-<pre class=prettyprint>
-<em>&lt;?<strong></em>xml version="1.0" encoding="utf-8"<em></strong>?>
-</em>&lt;<strong>layout xmlns:android="http://schemas.android.com/apk/res/android"</strong>>
-   &lt;<strong>data</strong>>
-       &lt;<strong>variable name="user" type="com.example.User"</strong>/>
-   &lt;/<strong>data</strong>>
-   &lt;<strong>LinearLayout
-       android:orientation="vertical"
-       android:layout_width="match_parent"
-       android:layout_height="match_parent"</strong>>
-       &lt;<strong>TextView android:layout_width="wrap_content"
-           android:layout_height="wrap_content"
-           android:text="&commat;{user.firstName}"</strong>/>
-       &lt;<strong>TextView android:layout_width="wrap_content"
-           android:layout_height="wrap_content"
-           android:text="&commat;{user.lastName}"</strong>/>
-   &lt;/<strong>LinearLayout</strong>>
-&lt;/<strong>layout</strong>>
-</pre>
-
-<p>The user <strong>variable</strong> within <strong>data</strong> describes a property that may be used within this layout.</p>
-
-<pre class=prettyprint>
-&lt;<strong>variable name="user" type="com.example.User"</strong>/>
-</pre>
-
-<p>Expressions within the layout are written in the attribute properties using the
-“<code>&commat;{}</code>” syntax. Here, the TextView’s text is set to the firstName property of user:</p>
-<pre class=prettyprint>
-&lt;<strong>TextView android:layout_width="wrap_content"
-          android:layout_height="wrap_content"
-          android:text="&commat;{user.firstName}"</strong>/>
-</pre>
-
-
-<h3 id="data_object">Data Object</h3>
-
-<p>Let’s assume for now that you have a plain-old Java object (POJO) for User:</p>
-<pre class=prettyprint>
-<strong>public class </strong>User {
-   <strong>public final </strong>String <strong>firstName</strong>;
-   <strong>public final </strong>String <strong>lastName</strong>;
-   <strong>public </strong>User(String firstName, String lastName) {
-       <strong>this</strong>.<strong>firstName </strong>= firstName;
-       <strong>this</strong>.<strong>lastName </strong>= lastName;
-   }
-}
-</pre>
-
-<p>This type of object has data that never changes. It is common in applications
-to have data that is read once and never changes thereafter. It is also
-possible to use a JavaBeans objects:</p>
-<pre class=prettyprint>
-<strong>public class </strong>User {
-   <strong>private final </strong>String <strong>firstName</strong>;
-   <strong>private final </strong>String <strong>lastName</strong>;
-   <strong>public </strong>User(String firstName, String lastName) {
-       <strong>this</strong>.<strong>firstName </strong>= firstName;
-       <strong>this</strong>.<strong>lastName </strong>= lastName;
-   }
-   <strong>public </strong>String getFirstName() {
-       <strong>return this</strong>.<strong>firstName</strong>;
-   }
-   <strong>public </strong>String getLastName() {
-       <strong>return this</strong>.<strong>lastName</strong>;
-   }
-}
-</pre>
-
-<p>From the perspective of data binding, these two classes are equivalent. The
-expression <strong><code>&commat;{user.lastName}</code></strong> used for the TextView’s <strong><code>android:text</code></strong> attribute will access the <strong><code>firstName</code></strong> field in the former class and the <code>getFirstName()</code> method in the latter class.
-</p><h3 id=binding_data>Binding Data</h3>
-
-<p>By default, a Binding class will be generated based on the name of the layout
-file, converting it to Pascal case and suffixing “Binding” to it. The above
-layout file was <code>activity_main.xml</code> so the generate class was <code>ActivityMainBinding</code>. This class holds all the bindings from the layout properties (e.g. the <code>user</code> variable) to the layout’s Views and knows how to assign values for the binding
-expressions.The easiest means for creating the bindings is to do it while inflating:
-</p>
-
-<pre class=prettyprint>
-&commat;Override
-<strong>protected void </strong>onCreate(Bundle savedInstanceState) {
-   <strong>super</strong>.onCreate(savedInstanceState);
-   ActivityMainBinding binding = DataBindingUtil.<em>setContentView</em>(<strong>this</strong>, R.layout.<em><strong>main_activity</strong></em>);
-   User user = <strong>new </strong>User(<strong>"Test"</strong>, <strong>"User"</strong>);
-   binding.setUser(user);
-}
-</pre>
-
-<p>You’re done! Run the application and you’ll see Test User in the UI.Alternatively, you can get the view via:
-</p><pre class=prettyprint>
-MainActivityBinding binding = MainActivityBinding.<em>inflate</em>(getLayoutInflater());
-</pre>
-
-<p>If you are using data binding items inside a ListView or RecyclerView adapter,
-you may prefer to use:
-</p><pre class=prettyprint>
-ListItemBinding binding = ListItemBinding.inflate(layoutInflater, viewGroup,
-false);
-//or
-ListItemBinding binding = DataBindingUtil.<em>inflate</em>(layoutInflater, R.layout.<em><strong>list_item</strong></em>, viewGroup, <strong>false</strong>);
-</pre>
-
-
-<h2 id=layout_details>Layout Details</h2>
-
-
-<h3 id=imports>Imports</h3>
-
-<p>Zero or more <strong><code>import</code></strong> elements may be used inside the <strong><code>data</code></strong> element. These allow easy reference to classes inside your layout file, just
-like in Java.
-</p><pre class=prettyprint>
-&lt;<strong>data</strong>>
-    &lt;<strong>import type="android.view.View"</strong>/>
-&lt;/<strong>data</strong>>
-</pre>
-
-<p>Now, View may be used within your binding expression:
-</p><pre class=prettyprint>
-&lt;<strong>TextView
-   android:text="&commat;{user.lastName}"
-   android:layout_width="wrap_content"
-   android:layout_height="wrap_content"
-   android:visibility="&commat;{user.isAdult ? View.VISIBLE : View.GONE}"</strong>/>
-</pre>
-
-<p>When there are class name conflicts, one of the classes may be renamed to an
-“alias:”</p>
-<pre class=prettyprint>
-&lt;<strong>import type="android.view.View"</strong>/>
-&lt;<strong>import type="com.example.real.estate.View"
-        alias="Vista"</strong>/>
-</pre>
-
-<p>Now, <strong><code>Vista</code></strong> may be used to reference the <code>com.example.real.estate.View</code> and <strong><code>View</code></strong> may be used to reference <code>android.view.View </code>within the layout file.Imported types may be used as type references in variables and expressions:</p>
-<pre class=prettyprint>
-&lt;<strong>data</strong>>
-    &lt;<strong>import type="com.example.User"</strong>/>
-    &lt;<strong>import type="java.util.List"</strong>/>
-    &lt;<strong>variable name="user" type="User"</strong>/>
-    &lt;<strong>variable name="userList" type="List&lt;User&gt;"</strong>/>
-&lt;/<strong>data</strong>>
-…
-&lt;<strong>TextView
-   android:text="&commat;{((User)(user.connection)).lastName}"
-   android:layout_width="wrap_content"
-   android:layout_height="wrap_content"</strong>/>
-</pre>
-
-<p>Imported types may also be used when referencing static fields and methods in
-expressions:</p>
-<pre class=prettyprint>
-&lt;<strong>data</strong>>
-    &lt;<strong>import type="com.example.MyStringUtils"</strong>/>
-    &lt;<strong>variable name="user" type="com.example.User"</strong>/>
-&lt;/<strong>data</strong>>
-…
-&lt;<strong>TextView
-   android:text="&commat;{MyStringUtils.capitalize(user.lastName)}"
-   android:layout_width="wrap_content"
-   android:layout_height="wrap_content"</strong>/>
-</pre>
-
-<p>Just as in Java, <code>java.lang.*</code> is imported automatically.</p>
-<h3 id=variables>Variables</h3>
-
-<p>Any number of <strong><code>variable</code></strong> elements may be used inside the <strong><code>data</code></strong> element. Each <strong><code>variable</code></strong> element describes a property that may be set on the layout to be used in
-binding expressions within the layout file.</p>
-<pre class=prettyprint>
-&lt;<strong>data</strong>>
-    &lt;<strong>import type="android.graphics.drawable.Drawable"</strong>/>
-    &lt;<strong>variable name="user"  type="com.example.User"</strong>/>
-    &lt;<strong>variable name="image" type="Drawable"</strong>/>
-    &lt;<strong>variable name="note"  type="String"</strong>/>
-&lt;/<strong>data</strong>>
-</pre>
-
-<p>The variable types are inspected at compile time, so if a variable implements <a href="#observable_objects">Observable</a>, <a href="#observable_collections">observable collection</a>, that should be reflected in the type. If the variable is a base class or
-  interface that does not implement the Observable* interface, the variables will <strong>not be</strong> observed!</p>
-
-<p>When there are different layout files for various configurations (e.g.
-landscape or portrait), the variables will be combined. There must not be
-conflicting variable definitions between these layout files.</p>
-
-<p>The generated binding class will have a setter and getter for each of the
-described variables. The variables will take the default Java values until the
-setter is called &mdash; <code>null</code> for reference types, <code>0</code> for <code>int</code>, <code>false</code> for <code>boolean</code>, etc.</p>
-
-<h3 id=custom_binding_class_names>Custom Binding Class Names</h3>
-
-<p>By default, a Binding class is generated based on the name of the layout file,
-starting it with upper-case, removing underscores ( _ ) and capitalizing the
-following letter and then suffixing “Binding”. This class will be placed in a
-databinding package under the module package. For example, the layout file <code>contact_item.xml</code> will generate <code>ContactItemBinding</code>. If the module package is <code>com.example.my.app</code>, then it will be placed in <code>com.example.my.app.databinding</code>.</p>
-
-<p>Binding classes may be renamed or placed in different packages by adjusting the <strong><code>class</code></strong> attribute of the <strong><code>data</code></strong> element. For example:</p>
-<pre class=prettyprint>
-&lt;<strong>data class="ContactItem"</strong>>
-    ...
-&lt;/<strong>data</strong>>
-</pre>
-
-<p>This generates the binding class as <code>ContactItem</code> in the databinding package in the module package. If the class should be
-generated in a different package within the module package, it may be prefixed
-with “.”:</p>
-<pre class=prettyprint>
-&lt;<strong>data class=".ContactItem"</strong>>
-    ...
-&lt;/<strong>data</strong>>
-</pre>
-
-In this case, <code>ContactItem</code> is generated in the module package directly.Any package may be used if the full package is provided:
-<pre class=prettyprint>
-&lt;<strong>data class="com.example.ContactItem"</strong>>
-    ...
-&lt;/<strong>data</strong>>
-</pre>
-
-
-<h3 id=includes>Includes</h3>
-
-<p>Variables may be passed into an included layout&apos;s binding from the containing
-layout by using the application namespace and the variable name in an
-attribute:</p>
-<pre class=prettyprint>
-<em>&lt;?<strong></em>xml version="1.0" encoding="utf-8"<em></strong>?>
-</em>&lt;<strong>layout xmlns:android="http://schemas.android.com/apk/res/android"
-</strong>       <strong> xmlns:bind="http://schemas.android.com/apk/res-auto"</strong>>
-   &lt;<strong>data</strong>>
-       &lt;<strong>variable name="user" type="com.example.User"</strong>/>
-   &lt;/<strong>data</strong>>
-   &lt;<strong>LinearLayout
-       android:orientation="vertical"
-       android:layout_width="match_parent"
-       android:layout_height="match_parent"</strong>>
-       &lt;<strong>include layout="&commat;layout/name"
-           bind:user="&commat;{user}"</strong>/>
-       &lt;<strong>include layout="&commat;layout/contact"
-           bind:user="&commat;{user}"</strong>/>
-   &lt;/<strong>LinearLayout</strong>>
-&lt;/<strong>layout</strong>>
-</pre>
-
-<p>Here, there must be a <code>user</code> variable in both the <code>name.xml </code>and <code>contact.xml </code>layout files.</p>
-<h3 id=expression_language>Expression Language</h3>
-
-
-<h4 id=common_features>Common Features</h4>
-
-<p>The expression language looks a lot like a Java expression. These are the same:</p>
-<ul>
-  <li> Mathematical <strong><code>+ - / * %</code></strong>
-  <li> String concatenation <strong><code>+</code></strong>
-  <li> <code>L</code>ogical <strong><code>&& ||</code></strong>
-  <li> Binary <strong><code>&</code> <code>|</code> <code>^</code></strong>
-  <li> Unary <strong><code>+ - ! ~</code></strong>
-  <li> Shift <strong><code>>> >>> <<</code></strong>
-  <li> Comparison <strong><code>== > < >= <=</code></strong>
-  <li> <strong><code>instanceof</code></strong>
-  <li> Grouping <strong><code>()</code></strong>
-  <li> Literals - character, String, numeric, <strong><code>null</code></strong>
-  <li> Cast
-  <li> Method calls
-  <li> Field access
-  <li> Array access <strong><code>[]</code></strong>
-  <li> Ternary operator <strong><code>?:</code></strong>
-</ul>
-<p>Examples:</p>
-<pre class=prettyprint>
-<strong>android:text="&commat;{String.valueOf(index + 1)}"
-android:visibility="&commat;{age &lt; 13 ? View.GONE : View.VISIBLE}"
-android:transitionName=&apos;&commat;{"image_" + id}&apos;</strong>
-</pre>
-
-
-<h4 id=missing_operations>Missing Operations</h4>
-
-<p>A few operations are missing from the expression syntax that you can use in
-Java.</p>
-<ul>
-  <li> <strong><code>this</code></strong>
-  <li> <strong><code>super</code></strong>
-  <li> <strong><code>new</code></strong>
-  <li> Explicit generic invocation
-</ul>
-
-<h4 id=null_coalescing_operator>Null Coalescing Operator</h4>
-
-<p>The null coalescing operator (<strong><code>??</code></strong>) chooses the left operand if it is not null or the right if it is null.</p>
-<pre class=prettyprint>
-<strong>android:text="&commat;{user.displayName ?? user.lastName}"</strong>
-</pre>
-
-<p>This is functionally equivalent to:</p>
-<pre class=prettyprint>
-<strong>android:text="&commat;{user.displayName != null ? user.displayName : user.lastName}"</strong>
-</pre>
-
-
-<h4 id=property_reference>Property Reference</h4>
-
-<p>The first was already discussed in the <a href="#writing_your_first_data_binding_expressions">Writing your first data binding expressions</a> above: short form JavaBean references. When an expression references a

-ObservableFields.</p>
-<pre class=prettyprint>
-<strong>android:text="&commat;{user.lastName}"</strong>
-</pre>
-
-
-<h4 id=collections>Collections</h4>
-
-<p>Common collections: arrays, lists, sparse lists, and maps, may be accessed
-using the <code>[]</code> operator for convenience.</p>
-<pre class=prettyprint>
-&lt;<strong>data</strong>>
-    &lt;<strong>import type="android.util.SparseArray"</strong>/>
-    &lt;<strong>import type="java.util.Map"</strong>/>

-    &lt;<strong>variable name="list" type="List&lt;String&gt;"</strong>/>
-    &lt;<strong>variable name="sparse" type="SparseArray&lt;String&gt;"</strong>/>
-    &lt;<strong>variable name="map" type="Map&lt;String, String&gt;"</strong>/>

-<strong>android:text="&commat;{map[key]}"
-</strong>
-</pre>
-
-
-<h4 id=string_literals>String Literals</h4>
-
-<p>When using single quotes around the attribute value, it is easy to use double
-quotes in the expression:</p>
-<pre class=prettyprint>
-<strong>android:text=&apos;&commat;{map["firstName"]}&apos;</strong>
-</pre>
-
-<p>It is also possible to use double quotes to surround the attribute value. When
-doing so, String literals should either use the &quot; or back quote (`).</p>
-<pre class=prettyprint>
-<strong>android:text="&commat;{map[`firstName`}"
-android:text="&commat;{map[&quot;firstName&quot;]}"</strong>
-</pre>
-

-<pre class=prettyprint>
-<strong>android:padding="&commat;{large? &commat;dimen/largePadding : &commat;dimen/smallPadding}"</strong>
-</pre>
-
-<p>Format strings and plurals may be evaluated by providing parameters:</p>
-<pre class=prettyprint>
-<strong>android:text="&commat;{&commat;string/nameFormat(firstName, lastName)}"

-<h2 id="data_objects">Data Objects</h2>
-
-
-<p>Any plain old Java object (POJO) may be used for data binding, but modifying a
-POJO will not cause the UI to update. The real power of data binding can be
-used by giving your data objects the ability to notify when data changes. There
-are three different data change notification mechanisms, <code>Observable </code>objects, <code>ObservableField</code>s, and <code>observable collections</code>.</p>
-
-<p>When one of these observable data object is bound to the UI and a property of
-the data object changes, the UI will be updated automatically.</p>
-
-<h3 id=observable_objects>Observable Objects</h3>
-
-
-<p>A class implementing <code>android.databinding.Observable</code> interface will allow the binding to attach a single listener to a bound object
-to listen for changes of all properties on that object.</p>
-
-<p>The <code>Observable</code> interface has a mechanism to add and remove listeners, but notifying is up to
-the developer. To make development easier, a base class, <code>BaseObservable,</code> was created to implement the listener registration mechanism. The data class
-implementer is still responsible for notifying when the properties change. This
-is done by assigning an <code>Bindable </code>annotation to the getter and notifying in the setter.</p>
-
-<pre class=prettyprint>
-<strong>private static class </strong>User <strong>extends </strong>BaseObservable {
-   <strong>private </strong>String <strong>firstName</strong>;
-   <strong>private </strong>String <strong>lastName</strong>;
-   &commat;Bindable
-   <strong>public </strong>String getFirstName() {
-       <strong>return this</strong>.<strong>firstName</strong>;
-   }
-   &commat;Bindable
-   <strong>public </strong>String getFirstName() {
-       <strong>return this</strong>.<strong>lastName</strong>;
-   }
-   <strong>public void </strong>setFirstName(String firstName) {
-       <strong>this</strong>.<strong>firstName </strong>= firstName;
-       notifyPropertyChanged(BR.firstName);
-   }
-   <strong>public void </strong>setLastName(String lastName) {
-       <strong>this</strong>.<strong>lastName </strong>= lastName;
-       notifyPropertyChanged(BR.lastName);
-   }
-}
-</pre>
-
-<p>The <code>Bindable </code>annotation generates an entry in the BR class file during compilation. The BR
-class file will be generated in the module package.If the base class for data classes cannot be changed, the <code>Observable</code> interface may be implemented using the convenient <code>PropertyChangeRegistry</code> to store and notify listeners efficiently.</p>
-
-<h3 id=observablefields>ObservableFields</h3>
-
-<p>A little work is involved in creating Observable classes, so developers who
-want to save time or have few properties may use ObservableFields.
-ObservableFields are self-contained observable objects that have a single
-field. There are versions for all primitive types and one for reference types.
-To use, create a public final field in the data class:</p>
-<pre class=prettyprint>
-<strong>private static class </strong>User <strong>extends </strong>BaseObservable {
-   <strong>public final </strong>ObservableField&lt;String> <strong>firstName </strong>=
-       <strong>new </strong>ObservableField&lt;>();
-   <strong>public final </strong>ObservableField&lt;String> <strong>lastName </strong>=
-       <strong>new </strong>ObservableField&lt;>();
-   <strong>public final </strong>ObservableInt <strong>age </strong>= <strong>new </strong>ObservableInt();
-}
-</pre>
-
-<p>That&apos;s it! To access the value, use the set and get accessor methods:</p>
-<pre class=prettyprint>
-user.<strong>firstName</strong>.set(<strong>"Google"</strong>);
-<strong>int </strong>age = user.<strong>age</strong>.get();
-</pre>
-
-
-<h3 id=observable_collections>Observable Collections</h3>
-
-<p>Some applications use more dynamic structures to hold data. Observable
-  collections allow keyed access to these data objects.ObservableArrayMap is useful when the key is a reference type, such as String.</p>
-
-<pre class=prettyprint>
-ObservableArrayMap&lt;String, Object> user = <strong>new </strong>ObservableArrayMap&lt;>();
-user.put(<strong>"firstName"</strong>, <strong>"Google"</strong>);
-user.put(<strong>"lastName"</strong>, <strong>"Inc."</strong>);
-user.put(<strong>"age"</strong>, 17);
-</pre>
-
-In the layout, the map may be accessed through the String keys:
-<pre class=prettyprint>
-&lt;<strong>data</strong>>
-    &lt;<strong>import type="android.databinding.ObservableMap"</strong>/>
-    &lt;<strong>variable name="user" type="ObservableMap&lt;String, Object>"</strong>/>
-&lt;/<strong>data</strong>>
-…
-&lt;<strong>TextView
-   android:text=&apos;&commat;{user["lastName"]}&apos;
-   android:layout_width="wrap_content"
-   android:layout_height="wrap_content"</strong>/>
-&lt;<strong>TextView
-   android:text=&apos;&commat;{String.valueOf(1 + (Integer)user["age"])}&apos;
-   android:layout_width="wrap_content"
-   android:layout_height="wrap_content"</strong>/>

-<p>ObservableArrayList is useful when the key is an integer:</p>
-<pre class=prettyprint>
-ObservableArrayList&lt;Object> user = <strong>new </strong>ObservableArrayList&lt;>();
-user.add(<strong>"Google"</strong>);
-user.add(<strong>"Inc."</strong>);
-user.add(17);
-</pre>
-
-<p>In the layout, the list may be accessed through the indices:</p>
-<pre class=prettyprint>
-&lt;<strong>data</strong>>
-    &lt;<strong>import type="android.databinding.ObservableList"</strong>/>
-    &lt;<strong>import type="com.example.my.app.Fields"</strong>/>
-    &lt;<strong>variable name="user" type="ObservableList&lt;Object>"</strong>/>
-&lt;/<strong>data</strong>>
-…
-&lt;<strong>TextView
-   android:text=&apos;&commat;{user[Fields.LAST_NAME]}&apos;
-   android:layout_width="wrap_content"
-   android:layout_height="wrap_content"</strong>/>
-&lt;<strong>TextView
-   android:text=&apos;&commat;{String.valueOf(1 + (Integer)user[Fields.AGE])}&apos;
-   android:layout_width="wrap_content"
-   android:layout_height="wrap_content"</strong>/>
-</pre>
-
-
-<h2 id=generated_binding>Generated Binding</h2>
-
-<p>The generated binding class links the layout variables with the Views within
-the layout. As discussed earlier, the name and package of the Binding may be <a href="#custom_binding_class_names">customized</a>. The Generated binding classes all extend <code>android.databinding.ViewDataBinding</code>.</p>
-<h3 id=creating>Creating</h3>
-
-<p>The binding should be created soon after inflation to ensure that the View
-hierarchy is not disturbed prior to binding to the Views with expressions
-within the layout. There are a few ways to bind to a layout. The most common is
-to use the static methods on the Binding class.The inflate method inflates the View hierarchy and binds to it all it one step.
-There are versions that attach the View to its parent and that inflate without
-attaching.</p>
-<pre class=prettyprint>
-MyLayoutBinding binding = MyLayoutBinding.<em>inflate</em>(<strong>this</strong>);
-MyLayoutBinding binding = MyLayoutBinding.<em>inflate</em>(viewGroup);
-</pre>
-
-<p>If the layout was inflated using a different mechanism, it may be bound
-separately:</p>
-<pre class=prettyprint>
-MyLayoutBinding binding = MyLayoutBinding.<em>bind</em>(viewRoot);
-</pre>
-
-<p>Sometimes the binding cannot be known in advance. In such cases, the binding
-can be created using the DataBindingUtil class:</p>
-<pre class=prettyprint>
-ViewDataBinding binding = DataBindingUtil.<em>inflate</em>(context, layoutId,
-    parent, attachToParent);
-ViewDataBinding binding = DataBindingUtil.<em>bindTo</em>(viewRoot, layoutId);
-</pre>
-
-
-<h3 id=views_with_ids>Views With IDs</h3>
-
-<p>A public final field will be generated for each View with an ID in the layout.
-The binding does a single pass on the View hierarchy, extracting the Views with
-IDs. This mechanism can be faster than calling findViewById for several Views. For example:</p>
-<pre class=prettyprint>
-&lt;<strong>layout xmlns:android="http://schemas.android.com/apk/res/android"</strong>>
-   &lt;<strong>data</strong>>
-       &lt;<strong>variable name="user" type="com.example.User"</strong>/>
-   &lt;/<strong>data</strong>>
-   &lt;<strong>LinearLayout
-       android:orientation="vertical"
-       android:layout_width="match_parent"
-       android:layout_height="match_parent"</strong>>
-       &lt;<strong>TextView android:layout_width="wrap_content"
-           android:layout_height="wrap_content"
-           android:text="&commat;{user.firstName}"
-</strong>           <strong>android:id="&commat;+id/firstName"</strong>/>
-       &lt;<strong>TextView android:layout_width="wrap_content"
-           android:layout_height="wrap_content"
-           android:text="&commat;{user.lastName}"</strong>           <strong>android:id="&commat;+id/lastName"</strong>/>
-   &lt;/<strong>LinearLayout</strong>>
-&lt;/<strong>layout</strong>>
-</pre>
-
-Will generate a binding class with:
-<pre class=prettyprint>
-<strong>public final </strong>TextView <strong>firstName</strong>;
-<strong>public final </strong>TextView <strong>lastName</strong>;
-</pre>
-
-<p>IDs are not nearly as necessary as without data binding, but there are still
-some instances where access to Views are still necessary from code.</p>
-<h3 id=variables>Variables</h3>
-
-<p>Each variable will be given a accessor methods.</p>
-<pre class=prettyprint>
-&lt;<strong>data</strong>>
-    &lt;<strong>import type="android.graphics.drawable.Drawable"</strong>/>
-    &lt;<strong>variable name="user"  type="com.example.User"</strong>/>
-    &lt;<strong>variable name="image" type="Drawable"</strong>/>
-    &lt;<strong>variable name="note"  type="String"</strong>/>
-&lt;/<strong>data</strong>>
-</pre>
-
-<p>will generate setters and getters in the binding:</p>
-<pre class=prettyprint>
-<strong>public abstract </strong>com.example.User getUser();
-<strong>public abstract void </strong>setUser(com.example.User user);
-<strong>public abstract </strong>Drawable getImage();
-<strong>public abstract void </strong>setImage(Drawable image);
-<strong>public abstract </strong>String getNote();
-<strong>public abstract void </strong>setNote(String note);
-</pre>
-
-
-<h3 id=viewstubs>ViewStubs</h3>
-
-<p>ViewStubs are a little different from normal Views. They start off invisible
-and when they either are made visible or are explicitly told to inflate, they
-replace themselves in the layout by inflating another layout.</p>
-
-<p>Because the ViewStub essentially disappears from the View hierarchy, the View
-in the binding object must also disappear to allow collection. Because the
-Views are final, a ViewStubProxy object takes the place of the ViewStub, giving
-the developer access to the ViewStub when it exists and also access to the
-inflated View hierarchy when the ViewStub has been inflated.</p>
-
-<p>When inflating another layout, a binding must be established for the new
-layout. Therefore, the ViewStubProxy must listen to the ViewStub&apos;s
-OnInflateListener and establish the binding at that time. Since only one can
-exist, the ViewStubProxy allows the developer to set an OnInflateListener on it
-that it will call after establishing the binding.</p>
-
-<h3 id=advanced_binding>Advanced Binding</h3>
-
-
-<h4 id=dynamic_variables>Dynamic Variables</h4>
-
-<p>At times, the specific binding class won&apos;t be known. For example, a
-RecyclerView Adapter operating against arbitrary layouts won&apos;t know the
-specific binding class. It still must assign the binding value during the
-onBindViewHolder.</p>
-
-<p>In this example, all layouts that the RecyclerView binds to have an "item"
-variable. The BindingHolder has a getBinding method returning the <code>ViewDataBinding</code> base.</p>
-<pre class=prettyprint>
-<strong>public void </strong>onBindViewHolder(BindingHolder holder, <strong>int </strong>position) {
-   <strong>final </strong>T item = <strong>mItems</strong>.get(position);
-   holder.getBinding().setVariable(BR.item, item);
-   holder.getBinding().executePendingBindings();
-}
-</pre>
-
-
-<h4 id=immediate_binding>Immediate Binding</h4>
-
-<p>When a variable or observable changes, the binding will be scheduled to change
-before the next frame. There are times, however, when binding must be executed
-immediately. To force execution, use the executePendingBindings() method.</p>
-<h2 id=attribute_setters>Attribute Setters</h2>
-
-<p>Whenever a bound value changes, the generated binding class must call a setter
-method on the View with the binding expression. The data binding framework has
-ways to customize which method to call to set the value.</p>
-<h3 id=automatic_setters>Automatic Setters</h3>
-
-For an attribute, data binding tries to find the method setAttribute. The
-namespace for the attribute does not matter, only the attribute name itself.
-
-<p>For example, an expression associated with TextView&apos;s attribute <strong><code>android:text</code></strong> will look for a setText(String). If the expression returns an int, data
-binding will search for a setText(int) method. Be careful to have the
-expression return the correct type, casting if necessary.Note that data binding will work even if no attribute exists with the given
-name. You can then easily "create" attributes for any setter by using data
-binding. For example, support DrawerLayout doesn&apos;t have any attributes, but
-plenty of setters. You can use the automatic setters to use one of these.</p>
-<pre class=prettyprint>
-&lt;android.support.v4.widget.<strong>DrawerLayout
-    android:layout_width="wrap_content"
-    android:layout_height="wrap_content"
-    app:scrimColor="&commat;{&commat;color/scrim}"
-    app:drawerListener="&commat;{fragment.drawerListener}"/></strong>
-</pre>
-
-
-<h3 id=renamed_setters>Renamed Setters</h3>
-
-<p>Some attributes have setters that don&apos;t match by name. For these methods, an
-attribute may be associated with the setter through BindingMethods annotation.
-This must be associated with a class and contains BindingMethod annotations,
-one for each renamed method. For example, the <strong><code>android:tint</code></strong> attribute is really associated with setImageTintList, not setTint.</p>
-<pre class=prettyprint>
-&commat;BindingMethods({
-       &commat;BindingMethod(type = <strong>"android.widget.ImageView"</strong>,
-                      attribute = <strong>"android:tint"</strong>,
-                      method = <strong>"setImageTintList"</strong>),
-})
-</pre>
-
-<p>It is unlikely that developers will need to rename setters; the android
-framework attributes have already been implemented.</p>
-<h3 id=custom_setters>Custom Setters</h3>
-
-<p>Some attributes need custom binding logic. For example, there is no associated
-setter for the <strong><code>android:paddingLeft</code></strong> attribute. Instead, setPadding(left, top, right, bottom) exists. A static
-binding adapter method with the BindingAdapter annotation allows the developer
-to customize how a setter for an attribute is called.</p>
-
-<p>The android attributes have already had BindingAdapters created. For example,
-here is the one for paddingLeft:</p>
-<pre class=prettyprint></p>
-&commat;BindingAdapter(<strong>"android:paddingLeft"</strong>)
-<strong>public static void </strong>setPaddingLeft(View view, <strong>int </strong>padding) {
-   view.setPadding(padding,
-                   view.getPaddingTop(),
-                   view.getPaddingRight(),
-                   view.getPaddingBottom());
-}
-</pre>
-
-<p>Binding adapters are useful for other types of customization. For example, a
-  custom loader can be called off-thread to load an image.</p>
-
-<p>Developer-created binding adapters will override the data binding default
-adapters when there is a conflict.</p>
-
-<p>You can also have adapters that receive multiple parameters. </p>
-<pre class=prettyprint>
-&commat;BindingAdapter(attributes = {<strong>"bind:imageUrl"</strong>, <strong>"bind:error"</strong>})
-<strong>public static void </strong>loadImage(ImageView view, String url, Drawable error) {
-   Picasso.<em>with</em>(view.getContext()).load(url).error(error).into(view);
-}
-</pre>
-
-<p>This adapter will be called if both <strong>imageUrl </strong>and <strong>error </strong>are used for an ImageView and <em>imageUrl </em>is a string and <em>error</em> is a drawable.</p>
-<ul>
-  <li> Custom namespaces are ignore during matching.
-  <li> You can also write adapters for android namespace.
-</ul>
-
-<pre class=prettyprint>
-&lt;ImageView app:imageUrl=“&commat;{venue.imageUrl}”
-app:error=“&commat;{&commat;drawable/venueError}”/>
-</pre>
-
-
-<h2 id=converters>Converters</h2>
-
-
-<h3 id=object_conversions>Object Conversions</h3>
-
-<p>When an Object is returned from a binding expression, a setter will be chosen
-from the automatic, renamed, and custom setters. The Object will be cast to a
-parameter type of the chosen setter.</p><p>This is a convenience for those using ObservableMaps to hold data. for example:</p>
-<pre class=prettyprint>
-&lt;<strong>TextView
-   android:text=&apos;&commat;{userMap["lastName"]}&apos;
-   android:layout_width="wrap_content"
-   android:layout_height="wrap_content"</strong>/>
-</pre>
-
-<p>The userMap returns an Object and that Object will be automatically cast to
-parameter type found in the setter <code>setText(CharSequence)</code>. When there may be confusion about the parameter type, the developer will need
-to cast in the expression.</p>
-<h3 id=custom_conversions>Custom Conversions</h3>
-
-<p>Sometimes conversions should be automatic between specific types. For example,
-when setting the background:</p>
-<pre class=prettyprint>
-&lt;<strong>View
-   android:background="&commat;{isError ? &commat;color/red : &commat;color/white}"
-   android:layout_width="wrap_content"
-   android:layout_height="wrap_content"</strong>/>
-</pre>
-
-<p>Here, the background takes a <code>Drawable</code>, but the color is an integer. Whenever a <code>Drawable</code> is expected and an integer is returned, the <code>int</code> should be converted to a <code>ColorDrawable</code>. This conversion is done using a static method with a BindingConversion
-annotation:</p>
-<pre class=prettyprint>
-&commat;BindingConversion
-<strong>public static </strong>ColorDrawable convertColorToDrawable(<strong>int </strong>color) {
-   <strong>return new </strong>ColorDrawable(color);
-}
-</pre>
-
-<p>Note that conversions only happen at the setter level, so it is <strong>not allowed </strong>to mix types like this:</p>
-<pre class=prettyprint>
-&lt;<strong>View
-   android:background="&commat;{isError ? &commat;drawable/error : &commat;color/white}"
-   android:layout_width="wrap_content"
-   android:layout_height="wrap_content"</strong>/>
-</pre>

+  This document explains how to use the Data Binding Library to write
+  declarative layouts and minimize the glue code necessary to bind your
+  application logic and layouts.
+</p>
+
+<h2 id="build_environment">
+  Build Environment
+</h2>
+
+<p>
+  <strong>Setting Up Work Environment:</strong>
+</p>
+
+<p>
+  To set up your application to use data binding, add data binding to the class
+  path of your build gradle file, right below "android".
+</p>
+
+<pre>
+   dependencies {
+       classpath <strong>"com.android.tools.build:gradle:1.2.3"
+       </strong>classpath <strong>"com.android.databinding:dataBinder:</strong>1.0-rc0"
+   }
+}
+</pre>
+<p>
+  Then make sure jcenter is in the repositories list for your sub projects.
+</p>
+
+<pre>
+allprojects {
+   repositories {
+       jcenter()
+   }
+}
+</pre>
+<p>
+  In each module you want to use data binding, apply the plugin right after
+  android plugin
+</p>
+
+<pre>
+apply plugin: ‘com.android.application&apos;
+apply plugin: &apos;<strong>com.android.databinding</strong>&apos;
+</pre>
+<p>
+  The data binding plugin is going to add necessary <strong>provided</strong>
+  and <strong>compile configuration</strong> dependencies to your project.
+</p>
+
+<h2 id="data_binding_layout_files">
+  Data Binding Layout Files
+</h2>
+
+<h3 id="writing_expressions">
+  Writing your first data binding expressions
+</h3>
+
+<p>
+  Data-binding layout files are slightly different and start with a root tag of
+  <strong>layout</strong> followed by a <strong>data</strong> element and a
+  <strong>view</strong> root element. This view element is what your root would
+  be in a non-binding layout file. A sample file looks like this:
+</p>
+
+<pre>
+<em>&lt;?</em><strong>xml version="1.0" encoding="utf-8"</strong><em>?&gt;
+</em>&lt;<strong>layout xmlns:android="http://schemas.android.com/apk/res/android"</strong>&gt;
+   &lt;<strong>data</strong>&gt;
+       &lt;<strong>variable name="user" type="com.example.User"</strong>/&gt;
+   &lt;/<strong>data</strong>&gt;
+   &lt;<strong>LinearLayout
+       android:orientation="vertical"
+       android:layout_width="match_parent"
+       android:layout_height="match_parent"</strong>&gt;
+       &lt;<strong>TextView android:layout_width="wrap_content"
+           android:layout_height="wrap_content"
+           android:text="&commat;{user.firstName}"</strong>/&gt;
+       &lt;<strong>TextView android:layout_width="wrap_content"
+           android:layout_height="wrap_content"
+           android:text="&commat;{user.lastName}"</strong>/&gt;
+   &lt;/<strong>LinearLayout</strong>&gt;
+&lt;/<strong>layout</strong>&gt;
+</pre>
+<p>
+  The user <strong>variable</strong> within <strong>data</strong> describes a
+  property that may be used within this layout.
+</p>
+
+<pre>
+&lt;<strong>variable name="user" type="com.example.User"</strong>/&gt;
+</pre>
+<p>
+  Expressions within the layout are written in the attribute properties using
+  the “<code>&commat;{}</code>” syntax. Here, the TextView’s text is set to the
+  firstName property of user:
+</p>
+
+<pre>
+&lt;<strong>TextView android:layout_width="wrap_content"
+          android:layout_height="wrap_content"
+          android:text="&commat;{user.firstName}"</strong>/&gt;
+</pre>
+<h3 id="data_object">
+  Data Object
+</h3>
+
+<p>
+  Let’s assume for now that you have a plain-old Java object (POJO) for User:
+</p>
+
+<pre>
+<strong>public class </strong>User {
+   <strong>public final </strong>String <strong>firstName</strong>;
+   <strong>public final </strong>String <strong>lastName</strong>;
+   <strong>public </strong>User(String firstName, String lastName) {
+       <strong>this</strong>.<strong>firstName </strong>= firstName;
+       <strong>this</strong>.<strong>lastName </strong>= lastName;
+   }
+}
+</pre>
+<p>
+  This type of object has data that never changes. It is common in applications
+  to have data that is read once and never changes thereafter. It is also
+  possible to use a JavaBeans objects:
+</p>
+
+<pre>
+<strong>public class </strong>User {
+   <strong>private final </strong>String <strong>firstName</strong>;
+   <strong>private final </strong>String <strong>lastName</strong>;
+   <strong>public </strong>User(String firstName, String lastName) {
+       <strong>this</strong>.<strong>firstName </strong>= firstName;
+       <strong>this</strong>.<strong>lastName </strong>= lastName;
+   }
+   <strong>public </strong>String getFirstName() {
+       <strong>return this</strong>.<strong>firstName</strong>;
+   }
+   <strong>public </strong>String getLastName() {
+       <strong>return this</strong>.<strong>lastName</strong>;
+   }
+}
+</pre>
+<p>
+  From the perspective of data binding, these two classes are equivalent. The
+  expression <strong><code>&commat;{user.firstName}</code></strong> used for
+  the TextView’s <strong><code>android:text</code></strong> attribute will
+  access the <strong><code>firstName</code></strong> field in the former class
+  and the <code>getFirstName()</code> method in the latter class.
+</p>
+
+<h3 id="binding_data">
+  Binding Data
+</h3>
+
+<p>
+  By default, a Binding class will be generated based on the name of the layout
+  file, converting it to Pascal case and suffixing “Binding” to it. The above
+  layout file was <code>activity_main.xml</code> so the generate class was
+  <code>ActivityMainBinding</code>. This class holds all the bindings from the
+  layout properties (e.g. the <code>user</code> variable) to the layout’s Views
+  and knows how to assign values for the binding expressions.The easiest means
+  for creating the bindings is to do it while inflating:
+</p>
+
+<pre>
+&commat;Override
+<strong>protected void </strong>onCreate(Bundle savedInstanceState) {
+   <strong>super</strong>.onCreate(savedInstanceState);
+   ActivityMainBinding binding = DataBindingUtil.<em>setContentView</em>(<strong>this</strong>, R.layout.<em><strong>main_activity</strong></em>);
+   User user = <strong>new </strong>User(<strong>"Test"</strong>, <strong>"User"</strong>);
+   binding.setUser(user);
+}
+</pre>
+<p>
+  You’re done! Run the application and you’ll see Test User in the UI.
+  Alternatively, you can get the view via:
+</p>
+
+<pre>
+MainActivityBinding binding = MainActivityBinding.<em>inflate</em>(getLayoutInflater());
+</pre>
+<p>
+  If you are using data binding items inside a ListView or RecyclerView
+  adapter, you may prefer to use:
+</p>
+
+<pre>
+ListItemBinding binding = ListItemBinding.inflate(layoutInflater, viewGroup,
+false);
+//or
+ListItemBinding binding = DataBindingUtil.<em>inflate</em>(layoutInflater, R.layout.<em><strong>list_item</strong></em>, viewGroup, <strong>false</strong>);
+</pre>
+<h2 id="layout_details">
+  Layout Details
+</h2>
+
+<h3 id="imports">
+  Imports
+</h3>
+
+<p>
+  Zero or more <strong><code>import</code></strong> elements may be used inside
+  the <strong><code>data</code></strong> element. These allow easy reference to
+  classes inside your layout file, just like in Java.
+</p>
+
+<pre>
+&lt;<strong>data</strong>&gt;
+    &lt;<strong>import type="android.view.View"</strong>/&gt;
+&lt;/<strong>data</strong>&gt;
+</pre>
+<p>
+  Now, View may be used within your binding expression:
+</p>
+
+<pre>
+&lt;<strong>TextView
+   android:text="&commat;{user.lastName}"
+   android:layout_width="wrap_content"
+   android:layout_height="wrap_content"
+   android:visibility="&commat;{user.isAdult ? View.VISIBLE : View.GONE}"</strong>/&gt;
+</pre>
+<p>
+  When there are class name conflicts, one of the classes may be renamed to an
+  “alias:”
+</p>
+
+<pre>
+&lt;<strong>import type="android.view.View"</strong>/&gt;
+&lt;<strong>import type="com.example.real.estate.View"
+        alias="Vista"</strong>/&gt;
+</pre>
+<p>
+  Now, <strong><code>Vista</code></strong> may be used to reference the
+  <code>com.example.real.estate.View</code> and
+  <strong><code>View</code></strong> may be used to reference
+  <code>android.view.View</code> within the layout file. Imported types may be
+  used as type references in variables and expressions:
+</p>
+
+<pre>
+&lt;<strong>data</strong>&gt;
+    &lt;<strong>import type="com.example.User"</strong>/&gt;
+    &lt;<strong>import type="java.util.List"</strong>/&gt;
+    &lt;<strong>variable name="user" type="User"</strong>/&gt;
+    &lt;<strong>variable name="userList" type="List&amp;lt;User&gt;"</strong>/&gt;
+    &lt;/<strong>data</strong>&gt;
+</pre>
+<p class="note">
+  <strong>Note</strong>: Android Studio does not yet handle imports so the
+  autocomplete for imported variables may not work in your IDE. Your
+  application will still compile fine and you can work around the IDE issue by
+  using fully qualified names in your variable definitions.
+</p>
+
+<pre>
+&lt;<strong>TextView
+   android:text="&commat;{((User)(user.connection)).lastName}"
+   android:layout_width="wrap_content"
+   android:layout_height="wrap_content"</strong>/&gt;
+</pre>
+<p>
+  Imported types may also be used when referencing static fields and methods in
+  expressions:
+</p>
+
+<pre>
+&lt;<strong>data</strong>&gt;
+    &lt;<strong>import type="com.example.MyStringUtils"</strong>/&gt;
+    &lt;<strong>variable name="user" type="com.example.User"</strong>/&gt;
+&lt;/<strong>data</strong>&gt;
+…
+&lt;<strong>TextView
+   android:text="&commat;{MyStringUtils.capitalize(user.lastName)}"
+   android:layout_width="wrap_content"
+   android:layout_height="wrap_content"</strong>/&gt;
+</pre>
+<p>
+  Just as in Java, <code>java.lang.*</code> is imported automatically.
+</p>
+
+<h3 id="variables">
+  Variables
+</h3>
+
+<p>
+  Any number of <strong><code>variable</code></strong> elements may be used
+  inside the <strong><code>data</code></strong> element. Each
+  <strong><code>variable</code></strong> element describes a property that may
+  be set on the layout to be used in binding expressions within the layout
+  file.
+</p>
+
+<pre>
+&lt;<strong>data</strong>&gt;
+    &lt;<strong>import type="android.graphics.drawable.Drawable"</strong>/&gt;
+    &lt;<strong>variable name="user"  type="com.example.User"</strong>/&gt;
+    &lt;<strong>variable name="image" type="Drawable"</strong>/&gt;
+    &lt;<strong>variable name="note"  type="String"</strong>/&gt;
+&lt;/<strong>data</strong>&gt;
+</pre>
+<p>
+  The variable types are inspected at compile time, so if a variable implements
+  <a href="#observable_objects">Observable</a> or is an <a href=
+  "#observable_collections">observable collection</a>, that should be reflected
+  in the type. If the variable is a base class or interface that does not
+  implement the Observable* interface, the variables will <strong>not
+  be</strong> observed!
+</p>
+
+<p>
+  When there are different layout files for various configurations (e.g.
+  landscape or portrait), the variables will be combined. There must not be
+  conflicting variable definitions between these layout files.
+</p>
+
+<p>
+  The generated binding class will have a setter and getter for each of the
+  described variables. The variables will take the default Java values until
+  the setter is called &mdash; <code>null</code> for reference types,
+  <code>0</code> for <code>int</code>, <code>false</code> for
+  <code>boolean</code>, etc.
+</p>
+
+<h3 id="custom_binding_class_names">
+  Custom Binding Class Names
+</h3>
+
+<p>
+  By default, a Binding class is generated based on the name of the layout
+  file, starting it with upper-case, removing underscores ( _ ) and
+  capitalizing the following letter and then suffixing “Binding”. This class
+  will be placed in a databinding package under the module package. For
+  example, the layout file <code>contact_item.xml</code> will generate
+  <code>ContactItemBinding</code>. If the module package is
+  <code>com.example.my.app</code>, then it will be placed in
+  <code>com.example.my.app.databinding</code>.
+</p>
+
+<p>
+  Binding classes may be renamed or placed in different packages by adjusting
+  the <strong><code>class</code></strong> attribute of the
+  <strong><code>data</code></strong> element. For example:
+</p>
+
+<pre>
+&lt;<strong>data class="ContactItem"</strong>&gt;
+    ...
+&lt;/<strong>data</strong>&gt;
+</pre>
+<p>
+  This generates the binding class as <code>ContactItem</code> in the
+  databinding package in the module package. If the class should be generated
+  in a different package within the module package, it may be prefixed with
+  “.”:
+</p>
+

+
+<h4 id="null_coalescing_operator">
+  Null Coalescing Operator

+</p>
+
+<pre>
+<strong>android:text="&commat;{user.displayName ?? user.lastName}"</strong>

+  Data Objects
+</h2>
+
+<p>
+  Any plain old Java object (POJO) may be used for data binding, but modifying
+  a POJO will not cause the UI to update. The real power of data binding can be
+  used by giving your data objects the ability to notify when data changes.
+  There are three different data change notification mechanisms,
+  <code>Observable</code> objects, <code>ObservableField</code>s, and
+  <code>observable collections</code>.
+</p>
+
+<p>
+  When one of these observable data object is bound to the UI and a property of
+  the data object changes, the UI will be updated automatically.
+</p>
+
+<h3 id="observable_objects">
+  Observable Objects
+</h3>
+
+<p>
+  A class implementing <code>android.databinding.Observable</code> interface
+  will allow the binding to attach a single listener to a bound object to
+  listen for changes of all properties on that object.
+</p>
+
+<p>
+  The <code>Observable</code> interface has a mechanism to add and remove
+  listeners, but notifying is up to the developer. To make development easier,
+  a base class, <code>BaseObservable,</code> was created to implement the
+  listener registration mechanism. The data class implementer is still
+  responsible for notifying when the properties change. This is done by
+  assigning a <code>Bindable</code> annotation to the getter and notifying in
+  the setter.
+</p>
+
+<pre>
+<strong>private static class </strong>User <strong>extends </strong>BaseObservable {
+   <strong>private </strong>String <strong>firstName</strong>;
+   <strong>private </strong>String <strong>lastName</strong>;
+   &commat;Bindable
+   <strong>public </strong>String getFirstName() {
+       <strong>return this</strong>.<strong>firstName</strong>;
+   }
+   &commat;Bindable
+   <strong>public </strong>String getFirstName() {
+       <strong>return this</strong>.<strong>lastName</strong>;
+   }
+   <strong>public void </strong>setFirstName(String firstName) {
+       <strong>this</strong>.<strong>firstName </strong>= firstName;
+       notifyPropertyChanged(BR.firstName);
+   }
+   <strong>public void </strong>setLastName(String lastName) {
+       <strong>this</strong>.<strong>lastName </strong>= lastName;
+       notifyPropertyChanged(BR.lastName);
+   }
+}
+</pre>
+<p>
+  The <code>Bindable</code> annotation generates an entry in the BR class file
+  during compilation. The BR class file will be generated in the module
+  package.If the base class for data classes cannot be changed, the
+  <code>Observable</code> interface may be implemented using the convenient
+  <code>PropertyChangeRegistry</code> to store and notify listeners
+  efficiently.
+</p>
+
+<h3 id="observablefields">
+  ObservableFields
+</h3>
+
+<p>
+  A little work is involved in creating Observable classes, so developers who
+  want to save time or have few properties may use ObservableFields.
+  ObservableFields are self-contained observable objects that have a single
+  field. There are versions for all primitive types and one for reference
+  types. To use, create a public final field in the data class:
+</p>
+
+<pre>
+<strong>private static class </strong>User <strong>extends </strong>BaseObservable {
+   <strong>public final </strong>ObservableField&lt;String&gt; <strong>firstName </strong>=
+       <strong>new </strong>ObservableField&lt;&gt;();
+   <strong>public final </strong>ObservableField&lt;String&gt; <strong>lastName </strong>=
+       <strong>new </strong>ObservableField&lt;&gt;();
+   <strong>public final </strong>ObservableInt <strong>age </strong>= <strong>new </strong>ObservableInt();
+}
+</pre>
+<p>
+  That&apos;s it! To access the value, use the set and get accessor methods:
+</p>
+
+<pre>
+user.<strong>firstName</strong>.set(<strong>"Google"</strong>);
+<strong>int </strong>age = user.<strong>age</strong>.get();
+</pre>
+<h3 id="observable_collections">
+  Observable Collections
+</h3>
+
+<p>
+  Some applications use more dynamic structures to hold data. Observable
+  collections allow keyed access to these data objects.ObservableArrayMap is
+  useful when the key is a reference type, such as String.
+</p>
+
+<pre>
+ObservableArrayMap&lt;String, Object&gt; user = <strong>new </strong>ObservableArrayMap&lt;&gt;();
+user.put(<strong>"firstName"</strong>, <strong>"Google"</strong>);
+user.put(<strong>"lastName"</strong>, <strong>"Inc."</strong>);
+user.put(<strong>"age"</strong>, 17);
+</pre>
+<p>
+  In the layout, the map may be accessed through the String keys:
+</p>
+
+<pre>
+&lt;<strong>data</strong>&gt;
+    &lt;<strong>import type="android.databinding.ObservableMap"</strong>/&gt;
+    &lt;<strong>variable name="user" type="ObservableMap&amp;lt;String, Object&gt;"</strong>/&gt;
+&lt;/<strong>data</strong>&gt;
+…
+&lt;<strong>TextView
+   android:text=&apos;&commat;{user["lastName"]}&apos;
+   android:layout_width="wrap_content"
+   android:layout_height="wrap_content"</strong>/&gt;
+&lt;<strong>TextView
+   android:text=&apos;&commat;{String.valueOf(1 + (Integer)user["age"])}&apos;
+   android:layout_width="wrap_content"
+   android:layout_height="wrap_content"</strong>/&gt;
+</pre>
+<p>
+  ObservableArrayList is useful when the key is an integer:
+</p>
+
+<pre>
+ObservableArrayList&lt;Object&gt; user = <strong>new </strong>ObservableArrayList&lt;&gt;();
+user.add(<strong>"Google"</strong>);
+user.add(<strong>"Inc."</strong>);
+user.add(17);
+</pre>
+<p>
+  In the layout, the list may be accessed through the indices:
+</p>
+
+<pre>
+&lt;<strong>data</strong>&gt;
+    &lt;<strong>import type="android.databinding.ObservableList"</strong>/&gt;
+    &lt;<strong>import type="com.example.my.app.Fields"</strong>/&gt;
+    &lt;<strong>variable name="user" type="ObservableList&amp;lt;Object&gt;"</strong>/&gt;
+&lt;/<strong>data</strong>&gt;
+…
+&lt;<strong>TextView
+   android:text=&apos;&commat;{user[Fields.LAST_NAME]}&apos;
+   android:layout_width="wrap_content"
+   android:layout_height="wrap_content"</strong>/&gt;
+&lt;<strong>TextView
+   android:text=&apos;&commat;{String.valueOf(1 + (Integer)user[Fields.AGE])}&apos;

+</pre>
+<h2 id="generated_binding">
+  Generated Binding
+</h2>
+
+<p>
+  The generated binding class links the layout variables with the Views within
+  the layout. As discussed earlier, the name and package of the Binding may be
+  <a href="#custom_binding_class_names">customized</a>. The Generated binding
+  classes all extend <code>android.databinding.ViewDataBinding</code>.
+</p>
+
+<h3 id="creating">
+  Creating
+</h3>
+
+<p>
+  The binding should be created soon after inflation to ensure that the View
+  hierarchy is not disturbed prior to binding to the Views with expressions
+  within the layout. There are a few ways to bind to a layout. The most common
+  is to use the static methods on the Binding class.The inflate method inflates
+  the View hierarchy and binds to it all it one step. There is a simpler
+  version that only takes a <code>LayoutInflater</code> and one that takes a
+  <code>ViewGroup</code> as well:
+</p>
+
+<pre>
+MyLayoutBinding binding = MyLayoutBinding.<em>inflate</em>(<strong>layoutInflater</strong>);
+MyLayoutBinding binding = MyLayoutBinding.<em>inflate</em>(LayoutInflater, viewGroup, false);
+</pre>
+<p>
+  If the layout was inflated using a different mechanism, it may be bound
+  separately:
+</p>
+
+<pre>
+MyLayoutBinding binding = MyLayoutBinding.<em>bind</em>(viewRoot);
+</pre>
+<p>
+  Sometimes the binding cannot be known in advance. In such cases, the binding
+  can be created using the DataBindingUtil class:
+</p>
+
+<pre>
+ViewDataBinding binding = DataBindingUtil.<em>inflate</em>(LayoutInflater, layoutId,
+    parent, attachToParent);
+ViewDataBinding binding = DataBindingUtil.<em>bindTo</em>(viewRoot, layoutId);
+</pre>
+<h3 id="views_with_ids">
+  Views With IDs
+</h3>
+
+<p>
+  A public final field will be generated for each View with an ID in the
+  layout. The binding does a single pass on the View hierarchy, extracting the
+  Views with IDs. This mechanism can be faster than calling findViewById for
+  several Views. For example:
+</p>
+
+<pre>
+&lt;<strong>layout xmlns:android="http://schemas.android.com/apk/res/android"</strong>&gt;
+   &lt;<strong>data</strong>&gt;
+       &lt;<strong>variable name="user" type="com.example.User"</strong>/&gt;
+   &lt;/<strong>data</strong>&gt;
+   &lt;<strong>LinearLayout
+       android:orientation="vertical"
+       android:layout_width="match_parent"
+       android:layout_height="match_parent"</strong>&gt;
+       &lt;<strong>TextView android:layout_width="wrap_content"
+           android:layout_height="wrap_content"
+           android:text="&commat;{user.firstName}"</strong>
+   <strong>android:id="&commat;+id/firstName"</strong>/&gt;
+       &lt;<strong>TextView android:layout_width="wrap_content"
+           android:layout_height="wrap_content"
+           android:text="&commat;{user.lastName}"</strong>
+  <strong>android:id="&commat;+id/lastName"</strong>/&gt;
+   &lt;/<strong>LinearLayout</strong>&gt;
+&lt;/<strong>layout</strong>&gt;
+</pre>
+<p>
+  Will generate a binding class with:
+</p>
+
+<pre>
+<strong>public final </strong>TextView <strong>firstName</strong>;
+<strong>public final </strong>TextView <strong>lastName</strong>;
+</pre>
+<p>
+  IDs are not nearly as necessary as without data binding, but there are still
+  some instances where access to Views are still necessary from code.
+</p>
+
+<h3 id="variables2">
+  Variables
+</h3>
+
+<p>
+  Each variable will be given accessor methods.
+</p>
+
+<pre>
+&lt;<strong>data</strong>&gt;
+    &lt;<strong>import type="android.graphics.drawable.Drawable"</strong>/&gt;
+    &lt;<strong>variable name="user"  type="com.example.User"</strong>/&gt;
+    &lt;<strong>variable name="image" type="Drawable"</strong>/&gt;
+    &lt;<strong>variable name="note"  type="String"</strong>/&gt;
+&lt;/<strong>data</strong>&gt;
+</pre>
+<p>
+  will generate setters and getters in the binding:
+</p>
+
+<pre>
+<strong>public abstract </strong>com.example.User getUser();
+<strong>public abstract void </strong>setUser(com.example.User user);
+<strong>public abstract </strong>Drawable getImage();
+<strong>public abstract void </strong>setImage(Drawable image);
+<strong>public abstract </strong>String getNote();
+<strong>public abstract void </strong>setNote(String note);
+</pre>
+<h3 id="viewstubs">
+  ViewStubs
+</h3>
+
+<p>
+  ViewStubs are a little different from normal Views. They start off invisible
+  and when they either are made visible or are explicitly told to inflate, they
+  replace themselves in the layout by inflating another layout.
+</p>
+
+<p>
+  Because the ViewStub essentially disappears from the View hierarchy, the View
+  in the binding object must also disappear to allow collection. Because the
+  Views are final, a ViewStubProxy object takes the place of the ViewStub,
+  giving the developer access to the ViewStub when it exists and also access to
+  the inflated View hierarchy when the ViewStub has been inflated.
+</p>
+
+<p>
+  When inflating another layout, a binding must be established for the new
+  layout. Therefore, the ViewStubProxy must listen to the ViewStub&apos;s
+  OnInflateListener and establish the binding at that time. Since only one can
+  exist, the ViewStubProxy allows the developer to set an OnInflateListener on
+  it that it will call after establishing the binding.
+</p>
+
+<h3 id="advanced_binding">
+  Advanced Binding
+</h3>
+
+<h4 id="dynamic_variables">
+  Dynamic Variables
+</h4>
+
+<p>
+  At times, the specific binding class won&apos;t be known. For example, a
+  RecyclerView Adapter operating against arbitrary layouts won&apos;t know the
+  specific binding class. It still must assign the binding value during the
+  onBindViewHolder.
+</p>
+
+<p>
+  In this example, all layouts that the RecyclerView binds to have an "item"
+  variable. The BindingHolder has a getBinding method returning the
+  <code>ViewDataBinding</code> base.
+</p>
+
+<pre>
+<strong>public void </strong>onBindViewHolder(BindingHolder holder, <strong>int </strong>position) {
+   <strong>final </strong>T item = <strong>mItems</strong>.get(position);
+   holder.getBinding().setVariable(BR.item, item);
+   holder.getBinding().executePendingBindings();
+}
+</pre>
+<h4 id="immediate_binding">
+  Immediate Binding
+</h4>
+
+<p>
+  When a variable or observable changes, the binding will be scheduled to
+  change before the next frame. There are times, however, when binding must be
+  executed immediately. To force execution, use the
+  <code>executePendingBindings()</code> method.
+</p>
+
+<h4>
+  Background Thread
+</h4>
+
+<p>
+  You can change your data model in a background thread as long as it is not a
+  collection. Data binding will localize each variable / field while evaluating
+  to avoid any concurrency issues.
+</p>
+
+<h2 id="attribute_setters">
+  Attribute Setters
+</h2>
+
+<p>
+  Whenever a bound value changes, the generated binding class must call a
+  setter method on the View with the binding expression. The data binding
+  framework has ways to customize which method to call to set the value.
+</p>
+
+<h3 id="automatic_setters">
+  Automatic Setters
+</h3>
+For an attribute, data binding tries to find the method setAttribute. The
+namespace for the attribute does not matter, only the attribute name itself.
+<p>
+  For example, an expression associated with TextView&apos;s attribute
+  <strong><code>android:text</code></strong> will look for a setText(String).
+  If the expression returns an int, data binding will search for a setText(int)
+  method. Be careful to have the expression return the correct type, casting if
+  necessary. Note that data binding will work even if no attribute exists with
+  the given name. You can then easily "create" attributes for any setter by
+  using data binding. For example, support DrawerLayout doesn&apos;t have any
+  attributes, but plenty of setters. You can use the automatic setters to use
+  one of these.
+</p>
+
+<pre>
+&lt;android.support.v4.widget.<strong>DrawerLayout
+    android:layout_width="wrap_content"
+    android:layout_height="wrap_content"
+    app:scrimColor="&commat;{&commat;color/scrim}"
+    app:drawerListener="&commat;{fragment.drawerListener}"/&gt;</strong>
+</pre>
+<h3 id="renamed_setters">
+  Renamed Setters
+</h3>
+
+<p>
+  Some attributes have setters that don&apos;t match by name. For these
+  methods, an attribute may be associated with the setter through
+  BindingMethods annotation. This must be associated with a class and contains
+  BindingMethod annotations, one for each renamed method. For example, the
+  <strong><code>android:tint</code></strong> attribute is really associated
+  with setImageTintList, not setTint.
+</p>
+
+<pre>
+&commat;BindingMethods({
+       &commat;BindingMethod(type = <strong>"android.widget.ImageView"</strong>,
+                      attribute = <strong>"android:tint"</strong>,
+                      method = <strong>"setImageTintList"</strong>),
+})
+</pre>
+<p>
+  It is unlikely that developers will need to rename setters; the android
+  framework attributes have already been implemented.
+</p>
+
+<h3 id="custom_setters">
+  Custom Setters
+</h3>
+
+<p>
+  Some attributes need custom binding logic. For example, there is no
+  associated setter for the <strong><code>android:paddingLeft</code></strong>
+  attribute. Instead, <code>setPadding(left, top, right, bottom)</code> exists.
+  A static binding adapter method with the <code>BindingAdapter</code>
+  annotation allows the developer to customize how a setter for an attribute is
+  called.
+</p>
+
+<p>
+  The android attributes have already had <code>BindingAdapter</code>s created.
+  For example, here is the one for <code>paddingLeft</code>:
+</p>
+
+<pre>
+
+&commat;BindingAdapter(<strong>"android:paddingLeft"</strong>)
+<strong>public static void </strong>setPaddingLeft(View view, <strong>int </strong>padding) {
+   view.setPadding(padding,
+                   view.getPaddingTop(),
+                   view.getPaddingRight(),
+                   view.getPaddingBottom());
+}
+</pre>
+<p>
+  Binding adapters are useful for other types of customization. For example, a
+  custom loader can be called off-thread to load an image.
+</p>
+
+<p>
+  Developer-created binding adapters will override the data binding default
+  adapters when there is a conflict.
+</p>
+
+<p>
+  You can also have adapters that receive multiple parameters.
+</p>
+
+<pre>
+&commat;BindingAdapter({<strong>"bind:imageUrl"</strong>, <strong>"bind:error"</strong>})
+<strong>public static void </strong>loadImage(ImageView view, String url, Drawable error) {
+   Picasso.<em>with</em>(view.getContext()).load(url).error(error).into(view);
+}
+</pre>
+<pre>
+&lt;ImageView app:imageUrl=“&commat;{venue.imageUrl}”
+app:error=“&commat;{&commat;drawable/venueError}”/&gt;
+</pre>
+
+<p>
+  This adapter will be called if both <strong>imageUrl</strong> and
+  <strong>error</strong> are used for an ImageView and <em>imageUrl</em> is a
+  string and <em>error</em> is a drawable.
+</p>
+
+<ul>
+  <li>Custom namespaces are ignored during matching.
+  </li>
+
+  <li>You can also write adapters for android namespace.
+  </li>
+</ul>
+
+<h2 id="converters">
+  Converters
+</h2>
+
+<h3 id="object_conversions">
+  Object Conversions
+</h3>
+
+<p>
+  When an Object is returned from a binding expression, a setter will be chosen
+  from the automatic, renamed, and custom setters. The Object will be cast to a
+  parameter type of the chosen setter.
+</p>
+
+<p>
+  This is a convenience for those using ObservableMaps to hold data. for
+  example:
+</p>
+
+<pre>
+&lt;<strong>TextView
+   android:text=&apos;&commat;{userMap["lastName"]}&apos;
+   android:layout_width="wrap_content"
+   android:layout_height="wrap_content"</strong>/&gt;
+</pre>
+
+<p>
+The <code>userMap</code> returns an Object and that Object will be automatically cast to
+  parameter type found in the setter <code>setText(CharSequence)</code>. When there
+  may be confusion about the parameter type, the developer will need
+  to cast in the expression.
+</p>
+
+<h3 id="custom_conversions">Custom Conversions</h3>
+
+<p>
+  Sometimes conversions should be automatic between specific types. For
+  example, when setting the background:
+</p>
+
+<pre>
+&lt;<strong>View
+   android:background="&commat;{isError ? &commat;color/red : &commat;color/white}"
+   android:layout_width="wrap_content"
+   android:layout_height="wrap_content"</strong>/&gt;
+</pre>
+<p>
+  Here, the background takes a <code>Drawable</code>, but the color is an
+  integer. Whenever a <code>Drawable</code> is expected and an integer is
+  returned, the <code>int</code> should be converted to a
+  <code>ColorDrawable</code>. This conversion is done using a static method
+  with a BindingConversion annotation:
+</p>
+
+<pre>
+&commat;BindingConversion
+<strong>public static </strong>ColorDrawable convertColorToDrawable(<strong>int </strong>color) {
+   <strong>return new </strong>ColorDrawable(color);
+}
+</pre>
+<p>
+  Note that conversions only happen at the setter level, so it is <strong>not
+  allowed</strong> to mix types like this:
+</p>
+
+<pre>
+&lt;<strong>View
+   android:background="&commat;{isError ? &commat;drawable/error : &commat;color/white}"
+   android:layout_width="wrap_content"
+   android:layout_height="wrap_content"</strong>/&gt;
+</pre>

   <p>Before downloading the NDK, you should understand that <strong>the NDK

   generally does not result in a noticable performance improvement,

-
-         <li>Removed GCC 4.6.</li>
-
-         <li>Implemented multithreading support in {@code ld.gold} for all architectures. It can

-            <ul>
-            <li>To compile with multithreading, use the {@code --threads} option.</li>
-            <li>To compile without multithreading, use the {@code --no-threads} option.</li>

-        <li>Fixed a crash that occurred when there were OpenMP loops outside of the main thread.</li>
-
-        <li>Fixed a GCC 4.9 internal compiler error (<i>ICE</i>) that occured when the user declared
-        {@code #pragma GCC optimize ("O0")}, but had a different level of optimization specified
-        on the command line. The {@code pragma} takes precedence.</li>
-

-        <li>Fixed a spurious array-bounds warning that GCC 4.9 produced for x86, and reenabled the
-        array bounds warning that GCC 4.9 had produced for ARM. The warning for ARM had
-        previously been unconditionally disabled.</li>
-
-        <li>Fixed Clang 3.5 for {@code mips} and {@code mips64} to create a writable
-            {@code .gcc_except_table} section, thus matching GCC behavior. This change allows you
-            to avoid the following linker warning:

-        </li>
-
-        <li>Fixed a {@code no rule to make target} error that occurred when compiling a single
-        {@code .c} file by executing the {@code ndk-build.cmd} command from {@code gradle}. (Issue
-        <a href="https://code.google.com/p/android/issues/detail?id=66937">66937</a>)</li>
-
-        <li>Added the {@code libatomic.a} and {@code libgomp.a} libraries that had been missing from

-     <dt>Other changes:</dt>
-     <dd>
-       <ul>
-       <li>Added {@code ld.gold} for {@code aarch64}. The default linker remains {@code ld.bfd}.
-       To explicitly enable {@code ld.gold}, add {@code -fuse-ld=gold} to the
-       {@code LOCAL_LDFLAGS} or {@code APP_LDFLAGS} variable.</li>
-
-       <li>Built the MIPS and MIPS64 toolchains with {@code binutils-2.25}, which provides improved

-
-       <li>Made {@code -fstandalone-debug} (full debug info) a default option for Clang.</li>
-
-       <li>Replaced {@code -fstack-protector} with {@code -fstack-protector-strong} for

-      <ul>
-        <li>Made GCC 4.8 the default for all 32-bit ABIs.  Deprecated GCC 4.6, and
-            will remove it next release. To restore previous behavior, either add
-            <code>NDK_TOOLCHAIN_VERSION=4.6</code> to ndk-build, or
-            add <code>--toolchain=arm-linux-androideabi-4.6</code> when executing
-            <code>make-standalone-toolchain.sh</code> on the command line. GCC 4.9 remains the
-            default for 64-bit ABIs.</li>
-
-         <li>Stopped all x86[_64] toolchains from adding <code>-mstackrealign</code> by default. The
-             NDK toolchain assumes a 16-byte stack alignment. The tools and options used by default
-             enforce this rule. A user writing assembly code must make sure to preserve stack
-             alignment, and ensure that other compilers also comply with this rule.

-
-         <li>Added Address Sanitizer functionality to Clang 3.5 support to the ARM and x86 ABIs.
-             For more information on this change, see the
-             <a href="https://code.google.com/p/address-sanitizer/wiki/Android">Address
-             Sanitizer</a> project.</li>
-
-         <li>Introduced the requirement, starting from API level 21, to use <code>-fPIE -pie
-             </code> when building. In API levels 16 and higher, ndk-build uses <code>PIE</code>
-             when building. This change has a number of implications, which are discussed in

-
-  <li>ARM and x86 default to using the integrated assembler. If this causes issues, use
-  <code>-fno-integrated-as</code> as a workaround.</code>
-  <li>Clang 3.5 issues more warnings for unused flags, such as the <code>-finline-functions</code>
-  option that GCC supports.</li>
-  <p>When migrating from projects using GCC, you can use
-  <code>-Wno-invalid-command-line-argument</code> and <code>-Wno-unused-command-line-argument</code>
-  to ignore the unused flags until you're able decide on what to do with them longer-term.</p>

-        for the <code>&lt;atomic&gt;</code> header.</li>
-        <li>Added <code>sys/ucontext.h</code> and <code>sys/user.h</code> to all API levels. The
-        <code>signal.h</code> header now includes <code>&lt;sys/ucontext.h&gt;</code>.  You may
-        remove any existing definition of <code>struct ucontext</code>.</li>
-        <li>Added <code>posix_memalign</code> to API levels 17, 18, and 19.</li>
-        <li>Added the following functions to all architectures:

-        sample.
-        (Issue <a href="https://android-review.googlesource.com/#/c/106640/">106640</a>)</li>
-        <li>Added <code>clock_nanosleep</code> and <code>clock_settime</code> to API level 21. (Issue
-        <a href="http://b.android.com/77372">77372</a>)
-        <li>Removed the following symbols from all architectures:
-        <code>get_malloc_leak_info</code>, <code>free_malloc_leak_info</code>,
-        <code>__srget</code>, <code>__swbuf</code>, <code>__srefill</code>, <code>__swsetup</code>,

-        <code>dirname_r</code>, <code>__isthreaded</code>, <code>_flush_cache</code> (mips64).</li>
-        <li>Removed the following function from the 32-bit architectures:
-        <code>__signalfd4</code>.</li>
-        <li>Changed the type of the third argument from <code>size_t</code> to <code>int</code> in
-        the following functions: <code>strtoll_l</code>, <code>strtoull_l</code>,
-        <code>wcstoll_l</code>, and <code>wcstoull_l</code>.</li>
-        <li>Restored the following functions to the 64-bit architecture: <code>arc4random</code>,
-        <code>arc4random_buf</code>, and <code>arc4random_uniform</code>.</li>
-        <li>Moved <code>cxa_*</code> and the <code>new</code> and <code>delete</code> operators back
-        to <code>libstdc++.so</code>. This change restores r9d behavior; previous versions of r10
-        contained dummy files.</li>
-
-        </ul>
-     <li>Restored MXU support in GCC 4.8 and 4.9 for mips. This support had been absent from
-     r10 and r10b because those versions of GCC had been compiled with binutils-2.24, which did
-     not support MXU. It now does.</li>
-     <li>Fixed <code>--toolchain=</code> in <code>make-standalone-toolchain.sh</code> so that it
-     now properly supports use of a suffix specifying a version of Clang.</li>
-     <li>Fixed the libc++/armeabi <code>strtod()</code> functions.</li>
-     <li>Made fixes to NDK documentation in <code>docs/</code>.</li>

-
-       <li>Modified ndk-build to use <code>*-gcc-ar</code>, which is available in GCC 4.8, GCC 4.9, and
-       Clang. Clang specifies it, instead of <code>*-ar</code>. This setting brings improved LTO
-       support.</li>

-      <dt>Important changes:</dt>
-      <dd>
-      <ul>
-        <li>Added 3 new ABIs, all 64-bit: arm64-v8a, x86_64, mips64.</li> Note that:
-        <ul>
-           <li>GCC 4.9 is the default compiler for 64-bit ABIs. Clang is currently version 3.4.
-<code>NDK_TOOLCHAIN_VERSION=clang</code>
-      may not work for arm64-v8a and mips64.</li>
-           <li>Android-L is the first level with 64-bit support.  Note that this API
-level is a temporary one, and only for L-preview. An actual API level number will replace it at
-L-release.</li>
-           <li>This release includes now includes <code>all32</code> and <code>all64</code>
-settings for <code>APP_ABI</code>.
-              <ul>
-              <li><code>APP_ABI=all32</code> is equivalent to
-<code>APP_ABI=armeabi,armeabi-v7a,x86,mips</code>.</li>
-              <li><code>APP_ABI=all64</code> is equivalent to
-<code>APP_ABI=arm64-v8a,x86_64,mips64</code>.</li>
-              <li><code>APP_ABI=all</code> selects all ABIs.</li>
-              </ul>
-           <li>The new GNU libstdc++ in Android-L contains all <code>&lt;tr1/cmath&gt;</code>
-Before defining your own math function, check <code>_GLIBCXX_USE_C99_MATH_TR1</code> to see a
-function with that name already exists, in order to avoid "multiple definition" errors from the
-linker.</li>
-           <li>The cpu-features library has been updated for the ARMv8 kernel.  The existing
-cpu-features library may fail to detect the presence of NEON on the ARMv8 platform. Recompile your
-code with the new version.</li>
-        </ul>
-        <li>Added a new <code>platforms/android-L/</code> API directory. It includes:</li>
-        <ul>
-           <li>Updated Bionic headers, which had not changed from Android API levels 3
-(Cupcake) to 19 (KitKat). This new version, for level L, is to be synchronized with AOSP.</li>
-           <li>New media APIs and a native-codec sample.</li>
-           <li>An updated <code>Android.h</code> header for SLES/OpenSLES, enabling support for
-single-precision, floating-point audio format in AudioPlayer.</li>
-           <li>GLES 3.1 and AEP extensions to <code>libGLESv3.so.</code></li>
-           <li>GLES2 and GLES3 headers updated to the latest official Khronos versions.</li>
-        </ul>
-        <li>Added GCC 4.9 compilers to the 32-/64-bit ABIs.  GCC 4.9 is the default (only) compiler
-for 64-bit ABIs, as previously mentioned.  For 32-bit ABIs, you must explcitly enable GCC 4.9, as
-GCC 4.6 is still the default.</li>
-        <ul>
-           <li>For ndk-build, enable 32-bit, GCC 4.9 building either by adding
-<code>NDK_TOOLCHAIN_VERSION=4.9</code> to <code>Application.mk</code>, or exporting it as an
-environment variable from the command line.</li>
-           <li>For a standalone toolchain, use the <code>--toolchain=</code> option in the
-<code>make-standalone-toolchain.sh</code> script. For example: <code>--toolchain=arm-linux-androideabi-4.9.</code></li>
-        </ul>
-        <li>Upgraded GDB to version 7.6 in GCC 4.8/4.9 and x86*. Since GDB is still at version GDB-7.3.x in
-GCC 4.6 (the default for ARM and MIPS), you must set
-<code>NDK_TOOLCHAIN_VERSION=4.8</code> or <code>4.9</code> to enable ndk-gdb to select GDB 7.6.</li>
-        <li>Added the <code>-mssse3</code> build option to provide SSSE3 support, and made it the default for ABI x86
-(upgrading from SSE3). The image released by Google does not contain SSSE3 instructions.</li>
-        <li>Updated GCC 4.8 to 4.8.3.</li>
-        <li>Improved ARM libc++ EH support by switching from gabi++ to libc++abi. For details, see the "C++ Support" section of the documentation.
-  Note that:</li>
-        <ul>
-           <li>All tests except for locale now pass for Clang 3.4 and GCC 4.8. For more
-information, see the "C++ Support" section of the documentation.</li>
-           <li>The libc++ libraries for X86 and MIPS libc++ still use gabi++.</li>
-           <li>GCC 4.7 and later can now use &lt;atomic&gt;.</li>
-           <li>You must add <code>-fno-strict-aliasing</code> if you use <code> &lt;list&gt;</code>, because <code>__list_imp::_end</code>_ breaks
-      TBAA rules.  (Issue <a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61571">61571</a>.)</li>
-           <li>As of GCC 4.6, LIBCXX_FORCE_REBUILD:=true no longer rebuilds libc++. Rebuilding it
-requires the use of a different compiler. Note that Clang 3.3 is untested.</li>
-        </ul>
-        <li>mclinker is now version 2.7, and has aarch64 Linux support.</li>
-        <li>Added precompiled header support for headers specified by <code>LOCAL_PCH</code>.  (Issue <a href="http://b.android.com/25412">25412</a>).</li>

-             <li>X86/MIPS: signed.
-             <li>ARM: unsigned.

-          </ul>
-          <li>Removed non-existent symbols from 32-bit <code>libc.so</code>, and added <code>pread64</code>,
-<code>pwrite64</code>, <code>ftruncate64</code> for
-Android API level 12 and higher. (Issue <a href="http://b.android.com/69319">69319</a>). For more

-     <a href="https://android-review.googlesource.com/#/c/94137">94137</a>.</li>
-       </ul>
-       <li>Fixed GCC warning about redefinition of <code>putchar</code>. Warning message reads:</li>

-[-Wattributes] int  putchar(int);</code> (Change list <a

-       </ul>
-       <li>Fixed GCC/Windows to quote arguments only when necessary for spawning processes in
-external programs. This change decreases the likelihood of exceeding the 32K length limit.</li>
-       <li>Fixed an issue that made it impossible to adjust the <code>APP_PLATFORM</code>
-environment variable.</li>
-       <li>Fixed the implementation of <code>IsSystemLibrary()</code> in crazy_linker so that it

-       <li>Fixed gdb's inability to print extreme floating-point numbers. (Issue <a
-href="http://b.android.com/69203">69203</a>).</li>
-       <li>Fixed Clang 3.4 inability to compile with <code>-Wl,-shared</code> (as opposed to
-<code>-shared</code>, which
-  had no compilation issues).  The problem was that Clang added <code>-pie</code> for Android
-targets if neither <code>-shared</code> nor <code>-static</code> existed. This behavior, which was
-incorrect, caused the linker to complain that <code>-shared</code> and <code>-pie</code> could not
-co-exist.</li>

-     <dt>Other changes:</dt>
-     <dd>
-     <ul>
-        <li>Added <code>arm_neon.h</code> to the x86 toolchain so that it now emulates ~47% of
-Neon. There is currently no support for 64-bit types. For more information, see the section on ARM
-Neon intrinsics support in the x86 documentation.</li>
-        <li>Ported ARM/GOT_PREL optimization (present in GCC 4.6 built from the GCC google branch) to
-ARM GCC 4.8/4.9.  This optimization sometimes reduces instruction count when accessing global
-variables.  As an example, see the build.sh script in

-      <dt>Important changes:</dt>
-      <dd>
-      <ul>
-        <li>Added support for the Clang 3.4 compiler. The
-<code>NDK_TOOLCHAIN_VERSION=clang</code> option now picks Clang 3.4. GCC 4.6 is
-still the default compiler.</li>
-        <li>Added <code>APP_ABI=armeabi-v7a-hard</code>, with
-additional multilib option <code>-mfloat-abi=hard</code>. These options are for
-use with ARM GCC 4.6/4.8 and Clang 3.3/3.4 (which use 4.8's assembler, linker,
-and libs). When using these options, note the following changes:</li>
-        <ul>
-           <li> When executing the <code>ndk-build</code> script, add the
-following options for armeabi-v7a target:
-<pre>TARGET_CFLAGS += -mhard-float -D_NDK_MATH_NO_SOFTFP=1
-TARGET_LDFLAGS += -Wl,--no-warn-mismatch -lm_hard</pre>
-The built library is copied to <code>libs/armeabi-v7a</code>. For make to
-behave as expected, you cannot specify both <code>armeabi-v7a</code> and
-<code>armeabi-v7a-hard</code> as make targets (i.e., on the APP_ABI= line).
-Doing so causes one of them to be ignored. Note that <code>APP_ABI=all</code>
-is still equivalent to
-<code>armeabi armeabi-v7a x86 mips</code>.</li>
-           <li>The <code>make-standalone-toolchain.sh</code> script copies
-additional libaries under <code>/hard</code> directories.
-      Add the above <code>CFLAGS</code> and <code>LFLAGS</code> to your
-makefile to enable GCC or Clang to link with
-      libraries in <code>/hard</code>.</li>
-        </ul>
-        <li>Added the yasm assembler, as well as <code>LOCAL_ASMFLAGS</code>
-and <code>EXPORT_ASMFLAGS</code> flags for x86
-targets. The <code>ndk-build</code> script uses
-<code>prebuilts/*/bin/yasm*</code> to build <code>LOCAL_SRC_FILES</code> that
-have the <code>.asm</code> extension.</li>
-        <li>Updated MClinker to 2.6.0, which adds <code>-gc-sections</code>
-support.</li>
-        <li>Added experimental libc++ support (upstream r201101).  Use this new
-feature by following these steps:
-        <ul>
-           <li>Add <code>APP_STL := c++_static</code> or <code>APP_STL :=
-c++_shared</code> in <code>Application.mk</code>.
-      You may rebuild from source via <code>LIBCXX_FORCE_REBUILD :=
-true</code></li>
-           <li>Execute <code>make-standalone-toolchain.sh --stl=libc++</code>
-to create a standalone toolchain with libc++ headers/lib.</li>
-        </ul>
-        For more information, see
-<code>CPLUSPLUS-SUPPORT.html</code>.

-     <dd>
-     <ul>
-       <li>Fixed an uncaught throw from an unexpected

-href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59392">59392</a>)</li>
-       <li>Fixed GCC 4.8 so that it now correctly resolves partial
-specialization of a template with
-  a dependent, non-type template argument. (GCC Issue <a
-href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59052">59052</a>)</li>
-       <li>Added more modules to prebuilt python (Issue <a
-href="http://b.android.com/59902">59902</a>):
-               <ul>
-                 <li>Mac OS X: <code>zlib</code>, <code>bz2</code>,

-       <li>Fixed the x86 and MIPS gdbserver
-<code>event_getmsg_helper</code>.</li>
-       <li>Fixed numerous issues in the RenderScript NDK toolchain, including

-     <dt>Other bug fixes:</dt>
-     <dd>
-     <ul>
-       <li>Header fixes:
-         <ul>
-           <li>Fixed a missing <code>#include &lt;sys/types.h&gt;</code> in
-<code>android/asset_manager.h</code> for Android API level 13 and higher.
-     (Issue <a href="http://b.android.com/64988">64988</a>)</li>
-           <li>Fixed a missing <code>#include <stdint.h></code> in
-<code>android/rect_manager.h</code> for Android API level 14 and higher.</li>
-           <li>Added <code>JNICALL</code> to <code>JNI_OnLoad</code> and
-<code>JNI_OnUnload</code> in <code>jni.h</code>. Note that <code>JNICALL</code>
- is defined as <code>__NDK_FPABI__</code> For more information, see
-<code>sys/cdefs.h</code>.</li>
-           <li>Updated the following headers so that they can be included
-without the need to
-manually include their dependencies (Issue <a
-href="http://b.android.com/64679">64679</a>):</li>
-<pre>
-android/tts.h
-EGL/eglext.h
-fts.h
-GLES/glext.h
-GLES2/gl2ext.h
-OMXAL/OpenMAXSL_Android.h
-SLES/OpenSLES_Android.h
-sys/prctl.h
-sys/utime.h
-</pre>
-           <li>Added <code>sys/cachectl.h</code> for all architectures. MIPS
-developers can now include this header instead of writing <code>#ifdef
-__mips__</code>.</li>
-           <li></code>Fixed <code>platforms/android-18/include/android/input.h
-</code> by adding <code>__NDK_FPABI__</code> to functions taking or returning
-float or double values.</li>
-           <li>Fixed MIPS <code>struct stat</code>, which was incorrectly set
-to its 64-bit counterpart for Android API level 12 and later. This wrong
-setting was a
-regression introduced in release r9c.</li>
-           <li>Defined <code>__PTHREAD_MUTEX_INIT_VALUE</code>,
-<code>__PTHREAD_RECURSIVE_MUTEX_INIT_VALUE</code>,
-     and <code>__PTHREAD_ERRORCHECK_MUTEX_INIT_VALUE</code> for Android API
-level 9 and lower.</li>
-           <li>Added <code>scalbln</code>, <code>scalblnf</code>, and
-<code>scalblnl</code> to x86 <code>libm.so</code> for APIs 18 and later.</li>
-           <li>Fixed a typo in
-<code>sources/android/support/include/iconv.h</code>.
-     (Issue <a href="http://b.android.com/63806">63806</a>)</li>
-
-         </ul>
-       </li>
-       <li>Fixed gabi++ <code>std::unexpected()</code> to call
-<code>std::terminate()</code> so that
-  a user-defined <code>std::terminate()</code> handler has a chance to run.
-</li>
-       <li>Fixed gabi++ to catch <code>std::nullptr</code>.</li>
-       <li>Fixed samples Teapot and MoreTeapots:
-         <ul>
-      <li>Solved a problem with Tegra 2 and 3 chips by changing specular
-variables to use medium precision. Values for specular power can now be less
-than 1.0. </li>
-      <li>Changed the samples so that pressing the volume button restores
-immersive mode and invalidates
-<code>SYSTEM_UI_FLAG_IMMERSIVE_STICKY</code>. Screen rotation does not
-trigger <code>onSystemUiVisibilityChange</code>, and so does not restore
-immersive mode.</li>
-         </ul>
-        </li>
-        <li>Fixed the <code>ndk-build</code> script to add
-<code>-rpath-link=$SYSROOT/usr/lib</code> and
-<code>-rpath-link=$TARGET_OUT</code> in order to use <code>ld.bfd</code> to
-link executables. (Issue  <a href="http://b.android.com/64266">64266</a>)</li>
-        <li>Removed <code>-Bsymbolic</code> from all STL builds.</li>
-        <li>Fixed <code>ndk-gdb-py.cmd</code> by setting <code>SHELL</code> as
-an environment variable
-instead of passing it to
-  <code>python.exe</code>, which ignores the setting.
-  (Issue <a href="http://b.android.com/63054">63054</a>)</li>
-        <li>Fixed the <code>make-standalone-toolchain.sh</code> script so that
-the <code>--stl=stlport</code> option copies the gabi++ headers instead of
-symlinking them; the <code>cmd.exe</code> and MinGW shells do not understand
-symlinks created by cygwin.</li>
-     </ul>
-     </dd>
-
-     <dt>Other changes:</dt>
-     <dd>
-     <ul>
-        <li>Applied execution permissions to all <code>*cmd</code> scripts
-previously intended for use only in the <code>cmd.exe</code> shell, in case
-developers prefer to use <code>ndk-build.cmd</code> in cygwin instead of the
-recommended <code>ndk-build</code> script.</li>
-        <li>Improved the speed of the <code>make-standalone-toolchain.sh</code>
-script by moving instead of copying if the specified destination directory does
-not exist.</li>

-     <dd>
-     <ul>
-       <li>Fixed a problem with GCC 4.8 ARM, in which the stack pointer is
-restored too early. This problem prevented the frame pointer from reliably
-accessing a variable in the stack frame. (GCC Issue <a
-href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58854">58854</a>)</li>
-<li>Fixed a problem with GCC 4.8 libstdc++, in which a bug in
-std::nth_element was causing generation of code that produced a random
-segfault. (Issue <a
-href="https://code.google.com/p/android/issues/detail?id=62910">62910</a>)</li>
-           <li>Fixed GCC 4.8 ICE in cc1/cc1plus with
-<code>-fuse-ld=mcld</code>, so that the following error no longer occurs:
-<pre>cc1: internal compiler error: in common_handle_option, at
-opts.c:1774</pre></li>
-           <li>Fixed <code>-mhard-float</code> support for

-     <ul>
-       <li>Header fixes:
-         <ul>
-           <li>Changed prototype of <code>poll</code> to <code>poll(struct
-pollfd *, nfds_t, int);</code> in <code>poll.h</code>.</li>
-           <li>Added <code>utimensat</code> to <code>libc.so</code> for Android
-API levels 12 and 19. These libraries are now included for all Android API
-levels 12 through 19.</li>
-<li>Introduced <code>futimens</code> into <code>libc.so</code>, for Android API
-level 19.</li>
-<li>Added missing <code>clock_settime()</code> and
-<code>clock_nanosleep()</code> to <code>time.h</code> for Android API level 8
-and higher.</li>
-<li>Added <code>CLOCK_MONOTONIC_RAW, CLOCK_REALTIME_COARSE,
-CLOCK_MONOTONIC_COARSE, CLOCK_BOOTTIME, CLOCK_REALTIME_ALARM,</code> and
-<code>CLOCK_BOOTTIME_ALARM</code> in <code>time.h.</code></li>
-<li>Removed obsolete <code>CLOCK_REALTIME_HR</code> and
-<code>CLOCK_MONOTONIC_HR.</code></li>
-         </ul>
-       </li>
-       <li>In samples Teapot, MoreTeapots, and
-<code>source/android/ndk_helper</code>:
-         <ul>
-<li>Changed them so that they now use a hard-float abi for armeabi-v7a.</li>
-<li>Updated them to use immersive mode on Android API level 19 and
-higher.</li>
-<li>Fixed a problem with <code>Check_ReleaseStringUTFChars</code> in
-<code>/system/lib/libdvm.so</code> that was causing crashes on x86 devices.</li>
-         </ul>
-        </li>
-<li>Fixed <code>ndk-build</code> fails that happen in cygwin when the NDK
-package is
-referenced via symlink.</li>
-<li>Fixed <code>ndk-build.cmd</code> fails that happen in windows
-<code>cmd.exe</code> when
-<code>LOCAL_SRC_FILES</code> contains absolute paths. (Issue <a
-href="https://android-review.googlesource.com/#/c/69992">69992</a>)</li>
-<li>Fixed the <code>ndk-stack</code> script to proceed even when it can't parse
-a frame due to inability to find a routine, filename, or line number. In any of
-these cases, it prints <code>??</code>.</li>
-<li>Fixed the <code>ndk-stack</code> stack for windows-x64_64 targets so that
-it no longer erroneously matches a frame line with a line in the
-<code>stack:</code> section that doesn't contain <code>pc</code>,
-<code>eip</code>, or <code>ip</code>. For example:
-<pre>I/DEBUG   ( 1151):     #00  5f09db68  401f01c4
-/system/lib/libc.so</pre></li>
-<li>Fixed gabi++ so that it:
-     <ul>
-         <li>Does not use malloc() to allocate C++ thread-local
-  objects.</li>

-
-     <dt>Other changes:</dt>
-     <dd>
-     <ul>
-       <li>Added <code>LOCAL_EXPORT_LDFLAGS</code>.</li>
-<li>Introduced the <code>NDK_PROJECT_PATH=null</code> setting for use in an
-integrated build system where options are explicitly passed to
-<code>ndk-build</code>. With this setting, <code>ndk-build</code> makes no
-attempt to look for <code>NDK_PROJECT_PATH.</code> This setting also prevents
-variables from deriving default settings from NDK_PROJECT_PATH. As a result,
-the following variables must now be explicitly specified (with their default
-values if such exist): <code>NDK_OUT, NDK_LIBS_OUT, APP_BUILD_SCRIPT,
-NDK_DEBUG</code> (optional, default to 0), and other <code>APP_*</code>'s
-contained in <code>Application.mk</code>.</li>
-<li><code>APP_ABI</code> can now be enumerated in a comma-delimited list. For
-example:
-<pre>APP_ABI := "armeabi,armeabi-v7a"</pre></li>
-<li>Provided the ability to rebuild all of STL with debugging info in an
-optional, separate package called
-<code>android-ndk-r9c-cxx-stl-libs-with-debugging-info.zip</code>, using the
-<code>-g</code> option. This option
-helps the <code>ndk-stack</code> script provide better a stack dump across STL.
-This change should not affect the code/size of the final, stripped file.</li>
-<li>Enhanced <code>hello-jni</code> samples to report <code>APP_ABI</code> at
-compilation.</li>
-<li>Used the <code>ar</code> tool in Deterministic mode (option
-<code>-D</code>) to build static libraries.  (Issue <a

-        <li>Enabled OpenMP for all GCC builds. To use this feature, add the following flags to your
-          build settings:
-<pre>
-LOCAL_CFLAGS += -fopenmp
-LOCAL_LDFLAGS += -fopenmp
-</pre>
-          For code examples, see {@code tests/device/test-openmp}</li>
-        <li>Reduced the size of {@code ld.mcld} significantly (1.5MB vs. {@code ld.bfd} 3.5MB and
-          {@code ld.gold} 7.5MB), resulting in a speed improvement of approximately 20%.</li>
-        <li>Added <code>LOCAL_CONLYFLAGS</code> and <code>APP_CONLYFLAGS</code> to specify
-          options applicable to C only but not C++. The existing <code>LOCAL_CFLAGS</code>
-          and <code>APP_CFLAGS</code> are also used for C++ compilation (to save trouble of
-          specifying most options twice), so options such as <code>-std=gnu99</code> may fail in
-          g++ builds with a warning and clang++ builds with an error.</li>
-        <li>Added {@code gabi++} array helper functions.</li>
-        <li>Modified GCC builds so that all {@code libgcc.a} files are built with
-          <code>-funwind-tables</code> to allow the stack to be unwound past previously blocked
-          points, such as <code>__aeabi_idiv0</code>.</li>
-        <li>Added Ingenic MXU support in MIPS GCC4.6/4.7/4.8 with new <code>-mmxu</code>
-option.</li>
-        <li>Extended MIPS GCC4.6/4.7/4.8 <code>-mldc1-sdc1</code> to control ldxc1/sdxc1 too</li>
-        <li>Added crazy linker. For more information, see
-          {@code sources/android/crazy_linker/README.TXT}.</li>
-        <li>Fixed {@code bitmap-plasma} to draw to full screen rather than a 200x200 pixel
-area.</li>
-        <li>Reduced linux and darwin toolchain sizes by 25% by creating symlinks to identical files.

-      <dd>
-        <ul>
-          <li>Added support for Android 4.3 (API level 18). For more information, see
-            {@code STABLE-APIS.html} and new code examples in {@code samples/gles3jni/README}.
-          <li>Added headers and libraries for OpenGL ES 3.0, which is supported by Android 4.3
-            (API level 18) and higher.</li>
-          <li>Added GNU Compiler Collection (GCC) 4.8 compiler to the NDK. Since GCC 4.6 is still
-            the default, you must explicitly enable this option:
-            <ul>
-              <li>For {@code ndk-build} builds, export {@code NDK_TOOLCHAIN_VERSION=4.8} or
-                add it in {@code Application.mk}.</li>
-              <li>For standalone builds, use the {@code --toolchain=} option in
-                {@code make-standalone-toolchain.sh}, for example:<br>
-                {@code --toolchain=arm-linux-androideabi-4.8}</li>
-            </ul>
-            <p class="note"><strong>Note:</strong>
-            The {@code -Wunused-local-typedefs} option is enabled by {@code -Wall}. Be
-            sure to add {@code __attribute__((unused))} if you use compile-time asserts like
-            {@code sources/cxx-stl/stlport/stlport/stl/config/features.h}, line #311. For more

-            <p class="note"><strong>Note:</strong>
-            In the GCC 4.7 release and later, ARM compilers generate unaligned access code by
-            default for ARMv6 and higher build targets. You may need to add the
-            {@code -mno-unaligned-access} build option when building for kernels that do not support
-            this feature.</p>
-          </li>
-          <li>Added Clang 3.3 support. The {@code NDK_TOOLCHAIN_VERSION=clang} build option
-            now picks Clang 3.3 by default.
-            <p class="note"><strong>Note:</strong>
-             Both GCC 4.4.3 and Clang 3.1 are deprecated, and will be removed from the next NDK
-             release.</p></li>
-          <li>Updated GNU Project Debugger (GDB) to support python 2.7.5.</li>
-          <li>Added MCLinker to support Windows hosts. Since {@code ld.gold}
-            is the default where available, you must add {@code -fuse-ld=mcld} in
-            {@code LOCAL_LDFLAGS} or {@code APP_LDFLAGS} to enable MCLinker.</li>
-          <li>Added {@code ndk-depends} tool which prints ELF library dependencies.

-          <li>Fixed Clang 3.2 X86/MIPS internal compiler error in {@code llvm/lib/VMCore/Value.cpp}.
-            (<a href="https://android-review.googlesource.com/#/c/59021">Change 59021</a>)</li>
-          <li>Fixed GCC 4.7 64-bit Windows assembler crash. (Error: {@code out of memory allocating
-            4294967280 bytes}).</li>
-          <li>Updated {@code ndk-gdb} script so that the {@code --start} or {@code --launch} actions
-            now wait for the GNU Debug Server, so that it can more reliably hit breakpoints set
-            early in the execution path (such as breakpoints in JNI code).

-            <p class="note"><strong>Note:</strong>
-              This feature requires jdb and produces warning about pending breakpoints.

-          <li>Fixed the {@code ndk-build} script to enable you to specify a version of Clang as a
-            command line option (e.g., {@code NDK_TOOLCHAIN_VERSION=clang3.2}). Previously, only
-            specifying the version as an environment variable worked.</li>

-                for API levels less than 9, which means that {@code wchat_t} is 32-bit for all

-            library in addition to {@code gnustl}, when you specify the option
-            {@code --stl=stlport}. For more information, see {@code STANDALONE-TOOLCHAIN.html}.</li>
-          <li>Updated the {@code make-standalone-toolchain.sh} script so that the
-            {@code --llvm-version=} option creates the {@code $TOOLCHAIN_PREFIX-clang} and
-            {@code $TOOLCHAIN_PREFIX-clang++} scripts in addition to {@code clang} and
-            {@code clang++}, to avoid using the host's clang and clang++ definitions by accident.
-            </li>
-          <li>Added two flags to re-enable two optimizations in upstream Clang but disabled in
-              NDK for better compatibility with code compiled by GCC:
-            <ul>
-              <li>Added a {@code -fcxx-missing-return-semantics} flag to re-enable <em>missing
-return
-                semantics</em> in Clang 3.2+. Normally, all paths should terminate with a return
-                statement for a value-returning function. If this is not the case, clang inserts
-                an undefined instruction (or trap in debug mode) at the path without a return
-                statement. If you are sure your code is correct, use this flag to allow the
-                optimizer to take advantage of the undefined behavior. If you are not sure, do not
-                use this flag. The caller may still receive a random incorrect value, but the
-                optimizer will not exploit it and make your code harder to debug.</li>
-              <li>Added a {@code -fglobal-ctor-const-promotion} flag to re-enable
-                promoting global variables with static constructor to be constants. With this flag,
-                the global variable optimization pass of LLVM tries to evaluate the global
-                variables with static constructors and promote them to global constants. Although
-                this optimization is correct, it may cause some incompatability with code compiled
-                by GCC. For example, code may do {@code const_cast} to cast the constant to mutable
-                and modify it. In GCC, the variable is in read-write and the code is run by
-                accident. In Clang, the const variable is in read-only memory and may cause your
-                application to crash.</li>
-            </ul>
-          </li>
-          <li>Added {@code -mldc1-sdc1} to the MIPS GCC and Clang compilers. By default, compilers
-            align 8-byte objects properly and emit the {@code ldc1} and {@code sdc1} instructions
-            to move them around. If your app uses a custom allocator that does not always align
-            with a new object's 8-byte boundary in the same way as the default allocator, your app
-            may crash due to {@code ldc1} and {@code sdc1} operations on unaligned memory. In this
-            case, use the {@code -mno-ldc1-sdc1} flag to workaround the problem.</li>
-          <li>Downgraded the event severity from warning to info if {@code APP_PLATFORM_LEVEL} is
-            larger than {@code APP_MIN_PLATFORM_LEVEL}. The {@code APP_PLATFORM_LEVEL} may be lower
-            than {@code APP_PLATFORM} in {@code jni/Application.mk} because the NDK does not have
-            headers for all levels. In this case, the actual level is shifted downwards. The
-            {@code APP_MIN_PLATFORM_LEVEL} is specified by the {@code android:minSdkVersion} in
-            your application's manifest.
-            (<a href="http://b.android.com/39752">Issue 39752</a>)</li>
-          <li>Added the {@code android_getCpuIdArm()} and {@code android_setCpuArm()} methods to
-            {@code cpu-features.c}. This addition enables easier retrieval of the ARM CPUID
-            information. (<a href="http://b.android.com/53689">Issue 53689</a>)</li>
-          <li>Modified {@code ndk-build} to use GCC 4.7's {@code as/ld} for Clang compiling.
-            <p class="note"><strong>Note:</strong>
-              In GCC 4.7, {@code monotonic_clock} and {@code is_monotonic} have been renamed to
-              {@code steady_clock} and {@code is_steady}, respectively.</p></li>
-          <li>Added the following new warnings to the {@code ndk-build} script:
-            <ul>
-              <li>Added warnings if {@code LOCAL_LDLIBS/LDFLAGS} are used in static library
-                modules.</li>
-              <li>Added a warning if a configuration has no module to build.</li>
-              <li>Added a warning for non-system libraries being used in
-                {@code LOCAL_LDLIBS/LDFLAGS} of a shared library or executable modules.</li>
-            </ul>
-          </li>
-          <li>Updated build scripts, so that if {@code APP_MODULES} is not defined and only static
-            libraries are listed in {@code Android.mk}, the script force-builds all of them.
-            (<a href="http://b.android.com/53502">Issue 53502</a>)</li>
-          <li>Updated {@code ndk-build} to support absolute paths in {@code LOCAL_SRC_FILES}.</li>
-          <li>Removed the {@code *-gdbtui} executables, which are duplicates of the {@code *-gdb}
-            executables with the {@code -tui} option enabled.</li>
-          <li>Updated the build scripts to warn you when the Edison Design Group (EDG) compiler
-            front-end turns {@code _STLP_HAS_INCLUDE_NEXT} back on.
-            (<a href="http://b.android.com/53646">Issue 53646</a>)</li>
-          <li>Added the environment variable {@code NDK_LIBS_OUT} to allow overriding of the
-            path for {@code libraries/gdbserver} from the default {@code $PROJECT/libs}.
-            For more information, see {@code OVERVIEW.html}.</li>
-          <li>Changed ndk-build script defaults to compile code with format string protection
-            {@code -Wformat -Werror=format-security}. You may set
-            {@code LOCAL_DISABLE_FORMAT_STRING_CHECKS=true} to disable it.
-            For more information, see {@code ANDROID-MK.html}</li>
-          <li>Added STL pretty-print support in {@code ndk-gdb-py}. For more information, see
-            {@code NDK-GDB.html}.</li>
-          <li>Added tests based on the googletest frameworks.</li>
-          <li>Added a notification to the toolchain build script that warns you if the current shell
-            is not {@code bash}.</li>

-        <ul>
-          <li>Added 64-bit host toolchain set (package name suffix {@code *-x86_64.*}). For more
-            information, see {@code CHANGES.HTML} and {@code NDK-BUILD.html}.</li>
-          <li>Added Clang 3.2 compiler. GCC 4.6 is still the default. For information on using the
-            Clang compiler, see {@code CHANGES.HTML}.</li>
-          <li>Added static code analyzer for Linux/MacOSX hosts. For information on using the
-            analyzer, see {@code CHANGES.HTML}.</li>
-          <li>Added MCLinker for Linux/MacOSX hosts as an experimental feature. The {@code ld.gold}

-            information, see {@code CHANGES.HTML}.</li>
-          <li>Updated ndk-build to use topological sort for module dependencies, which means the

-              <li>Updated {@code build-gabi++.sh} and {@code build-stlport.sh} so they can now run

-        <ul>
-          <li>Added the GNU Compiler Collection (GCC) 4.7 compiler to the NDK. The GCC 4.6 compiler
-            is still the default, so you must to explicitly enable the new version as follows:
-            <ul>
-              <li>For {@code ndk-build}, export the {@code NDK_TOOLCHAIN_VERSION=4.7} variable
-                <em>or</em> add it to {@code Application.mk}.</li>
-              <li>For standalone builds, add the {@code --toolchain=} option to
-                {@code make-standalone-toolchain.sh}, for example:
-                <pre>--toolchain=arm-linux-androideabi-4.7</pre></li>
-            </ul>

-          </li>
-          <li>Added {@code stlport} exception support via gabi++.  Note that the new gabi++
-            depends on {@code dlopen} and related code, meaning that:
-            <ul>
-              <li>You can no longer build a <em>static</em> executable using the {@code -static}
-                option or include {@code libstlport_static.a} using
-                {@code APP_STL := stlport_static}. (You can still use the {@code -static} option
-                with a standalone toolchain.) Compiling a <em>dynamic</em> executable using
-                {@code include $(BUILD_EXECUTABLE)} continues to work because the compiler
-                automatically adds the {@code -ldl} option.</li>
-              <li>If your project links using {@code -nostdlib} and {-Wl,--no-undefined}, you
-                must manually include the {@code -ldl} option.</li>

-                <strong>Note:</strong> This feature is experimental and works better with the GCC

-            and a new <em>tls</em> path (%gs:20) for {@code -fstack-protector},

-           (<a href="http://b.android.com/39585">Issue 39585</a>)</li>
-          <li>Fixed the {@code make-standalone-toolchain.sh} script to allow generation of a

-          <li>Added the Clang 3.1 compiler to the NDK. The GNU Compiler Collection (GCC) 4.6 is

-            <ul>

-          <li>Added Gold linker {@code ld.gold} for the Windows toolchain. Gold linker is also the
-            default for ARM and X86 on all hosts. You may override it to use the {@code ld.bfd}
-            linker by adding {@code LOCAL_LDFLAGS += -fuse-ld=bfd} to {@code Android.mk}, or by
-passing
-            {@code -fuse-ld=bfd} to the g++/clang++ command line that does the linking.</li>
-          <li>Added checks for spaces in the NDK path to the {@code ndk-build[.cmd]} and
-            {@code ndk-gdb} scripts, to prevent build errors that are difficult to diagnose.</li>
-          <li>Made the following changes to API level handling:
-            <ul>
-              <li>Modified build logic so that projects that specify {@code android-10} through
-                {@code android-13} in {@code APP_PLATFORM}, {@code project.properties} or
-                {@code default.properties} link against {@code android-9} instead of
-                {@code android-14}.
-              <li>Updated build so that executables using android-16 (Jelly Bean) or higher are
-                compiled with the {@code -fPIE} option for position-independent executables (PIE).
-                A new {@code APP_PIE} option allows you to control this behavior. See {@code

-                </p></li>
-              <li>Modified {@code ndk-build} to provide warnings if the adjusted API level is larger
-              than {@code android:minSdkVersion} in the project's {@code AndroidManifest.xml}.</li>
-            </ul>
-          </li>
-          <li>Updated the {@code cpu-features} helper library to include more ARM-specific features.
-          See {@code sources/android/cpufeatures/cpu-features.h} for details.</li>
-          <li>Modified the long double on the X86 platform to be 8 bytes. This data type is now the
-          same size as a double, but is still treated as a distinct type.</li>
-          <li>Updated build for {@code APP_ABI=armeabi-v7a}:
-            <ul>
-              <li>Modified this build type to pass the {@code -march=armv7-a} parameter
-              to the linker. This change ensures that v7-specific libraries and {@code crt*.o} are
-              linked correctly.</li>
-              <li>Added {@code -mfpu=vfpv3-d16} to {@code ndk-build} instead of the
-              {@code -mfpu=vfp} option used in previous releases.</li>

-          <li>Removed redundant {@code \r} from Windows prebuilt {@code echo.exe}. The redundant
-          {@code \r} caused {@code gdb.setup} to fail in the GNU Debugger (GDB) because it
-          incorrectly became part of the path.
-          (<a href="http://b.android.com/36054">Issue 36054</a>)</li>

-          {@code cp/mangle.c::write_unscoped_name}, where GCC may crash when the context is
-          {@code null} and dereferenced in {@code TREE_CODE}.</li>
-          <li>Fixed GCC 4.4.3 crashes on ARM NEON-specific type definitions for floats.
-          (<a href="http://b.android.com/34613">Issue 34613</a>)</li>
-          <li>Fixed the {@code STLport} internal {@code _IteWrapper::operator*()} implementation
-          where a stale stack location holding the dereferenced value was returned and caused
-          runtime crashes.
-          (<a href="http://b.android.com/38630">Issue 38630</a>)</li>

-          <li>ARM-specific fixes:

-              {@code -Wno-psabi} switch to avoid this warning is no longer required.</li>
-              <li>Fixed an issue when a project with {@code .arm} or {@code .neon} suffixes in

-              </li>
-              <li>Added fix to make repeated attempts to find {@code solib} breakpoints. GDB now
-              retries {@code enable_break()} during every call to {@code svr4_current_sos()} until

-              <li>Fixed preprocessor macros in {@code &lt;arch&gt;/include/machine/*}.</li>
-              <li>Replaced {@code link.h} for MIPS with new version supporting all platforms.</li>
-              <li>Removed {@code linux-unistd.h}</li>
-              <li>Move GLibc-specific macros {@code LONG_LONG_MIN}, {@code LONG_LONG_MAX} and

-          <li>Fixed {@code _STLP_USE_EXCEPTIONS}, when not defined, to omit all declarations
-          and uses of {@code __Named_exception}. Compiling and use of {@code __Named_exception}
-          settings only occurs when {@code STLport} is allowed to use exceptions.</li>
-          <li>Fixed building of Linux-only NDK packages without also building Windows code. Use the
-          following settings to perform this type of build:
-          <pre>./build/tools/make-release.sh --force --systems=linux-x86</pre></li>
-          <li>Fixed {@code libc.so} so it does not export {@code atexit()} and {@code __do_handler}.
-          These symbols are exported for ARM builds by the system version of the C library to
-          support legacy native libraries. NDK-generated should never reference them directly.
-          Instead, each shared library or executable should embed its own version of these symbols,
-          provided by {@code crtbegin_*.o}.
-          <p>If your project is linked with the {@code -nostdlib -Wl,--no-undefined} options, you
-          must provide your own {@code __dso_handle} because {@code crtbegin_so.o} is not linked in
-          this case. The content of {@code __dso_handle} does not matter, as shown in the following
-          example code:</p>
-<pre>
-extern "C" {
-  extern void *__dso_handle __attribute__((__visibility__ ("hidden")));
-  void *__dso_handle;
-}

-          </li>
-          <li>Fixed symbol decoder for ARM used in {@code objdump} for {@code plt} entries to
-          generate a more readable form {@code function@plt}.</li>
-          <li>Removed the following symbols, introduced in GCC 4.6 {@code libgcc.a}, from
-          the X86 platform {@code libc.so} library: {@code __aeabi_idiv0}, {@code __aeabi_ldiv0},
-          {@code __aeabi_unwind_cpp_pr1}, and {@code __aeabi_unwind_cpp_pr2}.</li>
-          <li>Removed unused {@code .ctors}, {@code .dtors}, and {@code .eh_frame} in MIPS
-          {@code crt*_so.S}.</li>
-          <li>Updated {@code ndk-gdb} so that it only takes the last line of output for
-          {@code ndk-build} {@code DUMP_XXXX}. This change ensures that if {@code Application.mk} or
-          {@code Android.mk} print something with {@code $(info ...)} syntax, it does not get
-          injected into the result of {@code DUMP_XXXX}.

-          without the {@code --abi} option, and is enhanced to compile most of the tests for all

-              <li>Added {@code --noexecstack} to assembler and {@code -z noexecstack} to linker
-that provides NX protection against buffer overflow attacks by enabling NX bit on stack and
-heap.</li>
-              <li>Added {@code -z relro} and  {@code -z now} to linker for hardening of internal
-data sections after linking to guard against security vulnerabilities caused by memory corruption.

-        <ul>
-          <li>Added support for the MIPS ABI, which allows you to generate machine code that runs on
-            compatible MIPS-based Android devices. Major features for MIPS include MIPS-specific
-            toolchains, system headers, libraries and debugging support. For more details regarding
-            MIPS support, see {@code docs/CPU-MIPS.html} in the NDK package.
-
-              <p>By default, code is generated for ARM-based devices. You can add {@code mips} to
-              your {@code APP_ABI} definition in your {@code Application.mk} file to build
-              for MIPS platforms. For example, the following line instructs {@code ndk-build}
-              to build your code for three distinct ABIs:</p>
-
-              <pre>APP_ABI := armeabi armeabi-v7a <strong>mips</strong></pre>
-
-              <p>Unless you rely on architecture-specific assembly sources, such as ARM assembly
-              code, you should not need to touch your {@code Android.mk} files to build MIPS
-              machine code.</p>
-          </li>
-
-          <li>You can build a standalone MIPS toolchain using the {@code --arch=mips}
-          option when calling <code>make-standalone-toolchain.sh</code>. See
-          {@code docs/STANDALONE-TOOLCHAIN.html} for more details.
-          </li>
-        </ul>
-
-        <p class="note"><strong>Note:</strong> To ensure that your applications are available
-to users only if their devices are capable of running them, Google Play filters applications based
-on the instruction set information included in your application ? no action is needed on your part
-to enable the filtering. Additionally, the Android system itself also checks your application at
-install time and allows the installation to continue only if the application provides a library that
-is compiled for the device's CPU architecture.</p>

-
-      <dd>
-        <ul>
-          <li>Updated {@code sys/atomics.h} to avoid correctness issues
-            on some multi-core ARM-based devices. Rebuild your unmodified sources with this
-            version of the NDK and this problem should be completely eliminated.
-            For more details, read {@code docs/ANDROID-ATOMICS.html}.</li>
-          <li>Reverted to {@code binutils} 2.19 to fix debugging issues that
-            appeared in NDK r7 (which switched to {@code binutils} 2.20.1).</li>
-          <li>Fixed {@code ndk-build} on 32-bit Linux. A packaging error put a 64-bit version
-            of the {@code awk} executable under {@code prebuilt/linux-x86/bin} in NDK r7.</li>
-          <li>Fixed native Windows build ({@code ndk-build.cmd}). Other build modes were not
-            affected. The fixes include:
-            <ul>
-              <li>Removed an infinite loop / stack overflow bug that happened when trying
-                to call {@code ndk-build.cmd} from a directory that was <em>not</em> the top of
-                your project path (e.g., in any sub-directory of it).</li>
-              <li>Fixed a problem where the auto-generated dependency files were ignored. This
-                meant that updating a header didn't trigger recompilation of sources that included
-                it.</li>
-              <li>Fixed a problem where special characters in files or paths, other than spaces and
-                quotes, were not correctly handled.</li>
-            </ul>
-          </li>
-          <li>Fixed the standalone toolchain to generate proper binaries when using
-            {@code -lstdc++} (i.e., linking against the GNU {@code libstdc++} C++ runtime). You
-            should use {@code -lgnustl_shared} if you want to link against the shared library
-            version or {@code -lstdc++} for the static version.
-
-            <p>See {@code docs/STANDALONE-TOOLCHAIN.html} for more details about this fix.</p>
-          </li>
-          <li>Fixed {@code gnustl_shared} on Cygwin. The linker complained that it couldn't find
-            {@code libsupc++.a} even though the file was at the right location.</li>
-          <li>Fixed Cygwin C++ link when not using any specific C++ runtime through
-            {@code APP_STL}.</li>

-      <dt>Other changes:</dt>
-
-      <dd>
-        <ul>
-          <li>When your application uses the GNU {@code libstdc++} runtime, the compiler will
-            no longer forcibly enable exceptions and RTTI. This change results in smaller code.
-            <p>If you need these features, you must do one of the following:</p>
-            <ul>
-              <li>Enable exceptions and/or RTTI explicitly in your modules or
-                {@code Application.mk}. (recommended)</li>
-              <li>Define {@code APP_GNUSTL_FORCE_CPP_FEATURES} to {@code 'exceptions'},
-                {@code 'rtti'} or both in your {@code Application.mk}. See
-                {@code docs/APPLICATION-MK.html} for more details.</li>
-            </ul>
-          </li>
-          <li>{@code ndk-gdb} now works properly when your application has private services
-            running in independent processes. It debugs the main application process, instead of the
-            first process listed by {@code ps}, which is usually a service process.</li>
-          <li>Fixed a rare bug where NDK r7 would fail to honor the {@code LOCAL_ARM_MODE} value
-            and always compile certain source files (but not all) to 32-bit instructions.</li>
-          <li>{@code STLport}: Refresh the sources to match the Android platform version. This
-            update fixes a few minor bugs:
-            <ul>
-               <li>Fixed instantiation of an incomplete type</li>
-               <li>Fixed minor "==" versus "=" typo</li>
-               <li>Used {@code memmove} instead of {@code memcpy} in {@code string::assign}</li>
-               <li>Added better handling of {@code IsNANorINF}, {@code IsINF}, {@code IsNegNAN},
-                 etc.</li>
-             </ul>
-             <p>For complete details, see the commit log.</p>
-          </li>
-          <li>{@code STLport}: Removed 5 unnecessary static initializers from the library.</li>
-          <li>The GNU libstdc++ libraries for armeabi-v7a were mistakenly compiled for
-            armeabi instead. This change had no impact on correctness, but using the right
-            ABI should provide slightly better performance.</li>
-          <li>The {@code cpu-features} helper library was updated to report three optional
-            x86 CPU features ({@code SSSE3}, {@code MOVBE} and {@code POPCNT}). See
-            {@code docs/CPU-FEATURES.html} for more details.</li>
-          <li>{@code docs/NDK-BUILD.html} was updated to mention {@code NDK_APPLICATION_MK} instead
-            of {@code NDK_APP_APPLICATION_MK} to select a custom {@code Application.mk} file.</li>
-          <li>Cygwin: {@code ndk-build} no longer creates an empty "NUL" file in the current
-            directory when invoked.</li>
-          <li>Cygwin: Added better automatic dependency detection. In the previous version, it
-            didn't work properly in the following cases:
-            <ul>
-              <li>When the Cygwin drive prefix was not {@code /cygdrive}.</li>
-              <li>When using drive-less mounts, for example, when Cygwin would translate
-                {@code /home} to {@code \\server\subdir} instead of {@code C:\Some\Dir}.</li>
-            </ul>
-          </li>
-          <li>Cygwin: {@code ndk-build} does not try to use the native Windows tools under
-            {@code $NDK/prebuilt/windows/bin} with certain versions of Cygwin and/or GNU Make.</li>

-    <p>This release of the NDK includes new features to support the Android 4.0 platform as well
-    as many other additions and improvements:</p>
-
-    <dl>
-      <dt>New features</dt>
-
-      <dd>
-        <ul>
-          <li>Added official NDK APIs for Android 4.0 (API level 14), which adds the following
-          native features to the platform:
-
-            <ul>
-              <li>Added native multimedia API based on the Khronos Group OpenMAX AL? 1.0.1
-              standard. The new <code>&lt;OMXAL/OpenMAXAL.h&gt;</code> and
-              <code>&lt;OMXAL/OpenMAXAL_Android.h&gt;</code> headers allow applications targeting
-              API level 14 to perform multimedia output directly from native code by using a new
-              Android-specific buffer queue interface. For more details, see
-              <code>docs/openmaxal/index.html</code> and <a href=
-              "http://www.khronos.org/openmax/">http://www.khronos.org/openmax/</a>.</li>
-
-              <li>Updated the native audio API based on the Khronos Group OpenSL ES 1.0.1?
-              standard. With API Level 14, you can now decode compressed audio (e.g. MP3, AAC,
-              Vorbis) to PCM. For more details, see <code>docs/opensles/index.html</code> and
-              <a href=
-              "http://www.khronos.org/opensles">http://www.khronos.org/opensles/</a>.</li>
-            </ul>
-          </li>
-
-          <li>Added CCache support. To speed up large rebuilds, define the
-          <code>NDK_CCACHE</code> environment variable to <code>ccache</code> (or the path to
-          your <code>ccache</code> binary). When declared, the NDK build system automatically
-          uses CCache when compiling any source file. For example:
-            <pre>
-export NDK_CCACHE=ccache
-</pre>
-          <p class="note"><strong>Note:</strong> CCache is not included in the NDK release
-          so you must have it installed prior to using it. For more information about CCache, see
-          <a href="http://ccache.samba.org">http://ccache.samba.org</a>.</p>
-          </li>
-
-          <li>Added support for setting <code>APP_ABI</code> to <code>all</code> to indicate that
-          you want to build your NDK modules for all the ABIs supported by your given NDK
-          release. This means that either one of the following two lines in your
-          <code>Application.mk</code> are equivalent with this release:
-            <pre>
-APP_ABI := all
-APP_ABI := armeabi armeabi-v7a x86
-</pre>
-
-            <p>This also works if you define <code>APP_ABI</code> when calling
-            <code>ndk-build</code> from the command-line, which is a quick way to check that your
-            project builds for all supported ABIs without changing the project's
-            <code>Application.mk file</code>. For example:</p>
-            <pre>
-ndk-build APP_ABI=all
-</pre>
-          </li>
-
-          <li>Added a <code>LOCAL_CPP_FEATURES</code> variable in <code>Android.mk</code> that
-          allows you to declare which C++ features (RTTI or Exceptions) your module uses. This
-          ensures that the final linking works correctly if you have prebuilt modules that depend
-          on these features. See <code>docs/ANDROID-MK.html</code> and
-          <code>docs/CPLUSPLUS-SUPPORT.html</code> for more details.</li>
-
-          <li>Shortened paths to source and object files that are used in build commands. When
-          invoking <code>$NDK/ndk-build</code> from your project path, the paths to the source,
-          object, and binary files that are passed to the build commands are significantly
-          shorter now, because they are passed relative to the current directory. This is useful
-          when building projects with a lot of source files, to avoid limits on the maximum
-          command line length supported by your host operating system. The behavior is unchanged
-          if you invoke <code>ndk-build</code> from a sub-directory of your project tree, or if
-          you define <code>NDK_PROJECT_PATH</code> to point to a specific directory.</li>

-        You can now build your NDK source files on Windows <em>without</em> Cygwin by calling the
-        <code>ndk-build.cmd</code> script from the command line from your project path. The
-        script takes exactly the same arguments as the original <code>ndk-build</code> script.
-        The Windows NDK package comes with its own prebuilt binaries for GNU Make, Awk and other
-        tools required by the build. You should not need to install anything else to get a
-        working build system.
-
-        <p class="caution"><strong>Important:</strong> <code>ndk-gdb</code> does not work on
-        Windows, so you still need Cygwin to debug.</p>
-
-        <p>This feature is still experimental, so feel free to try it and report issues on the
-        <a href="http://b.android.com">public bug database</a> or <a href=
-        "http://groups.google.com/group/android-ndk">public forum</a>. All samples and unit tests
-        shipped with the NDK succesfully compile with this feature.</p>

-
-      <dd>
-        <ul>
-          <li>Imported shared libraries are now installed by default to the target installation
-          location (<code>libs/&lt;abi&gt;</code>) if <code>APP_MODULES</code> is not defined in
-          your <code>Application.mk</code>. For example, if a top-level module <code>foo</code>
-          imports a module <code>bar</code>, then both <code>libfoo.so</code> and
-          <code>libbar.so</code> are copied to the install location. Previously, only
-          <code>libfoo.so</code> was copied, unless you listed <code>bar</code> in your
-          <code>APP_MODULES</code> too. If you define <code>APP_MODULES</code> explicitly, the
-          behavior is unchanged.</li>
-
-          <li><code>ndk-gdb</code> now works correctly for activities with multiple categories in
-          their MAIN intent filters.</li>
-
-          <li>Static library imports are now properly transitive. For example, if a top-level
-          module <code>foo</code> imports static library <code>bar</code> that imports static
-          library <code>zoo</code>, the <code>libfoo.so</code> will now be linked against both
-          <code>libbar.a</code> and <code>libzoo.a</code>.</li>
-        </ul>
-      </dd>
-
-      <dt>Other changes</dt>
-
-      <dd>
-        <ul>
-          <li><code>docs/NATIVE-ACTIVITY.HTML</code>: Fixed typo. The minimum API level should be
-          9, not 8 for native activities.</li>
-
-          <li><code>docs/STABLE-APIS.html</code>: Added missing documentation listing EGL as a
-          supported stable API, starting from API level 9.</li>
-
-          <li><code>download-toolchain-sources.sh</code>: Updated to download the toolchain
-          sources from <a href="http://android.googlesource.com">android.googlesource.com</a>,
-          which is the new location for the AOSP servers.</li>
-
-          <li>Added a new C++ support runtime named <code>gabi++</code>. More details about it
-          are available in the updated <code>docs/CPLUSPLUS-SUPPORT.html</code>.</li>
-
-          <li>Added a new C++ support runtime named <code>gnustl_shared</code> that corresponds
-          to the shared library version of GNU libstdc++ v3 (GPLv3 license). See more info at
-          <code>docs/CPLUSPLUS-SUPPORT.html</code></li>
-
-          <li>Added support for RTTI in the STLport C++ runtimes (no support for
-          exceptions).</li>
-
-          <li>Added support for multiple file extensions in <code>LOCAL_CPP_EXTENSION</code>. For
-          example, to compile both <code>foo.cpp</code> and <code>bar.cxx</code> as C++ sources,
-          declare the following:
-            <pre>
-LOCAL_CPP_EXTENSION := .cpp .cxx
-</pre>
-          </li>
-
-          <li>Removed many unwanted exported symbols from the link-time shared system libraries
-          provided by the NDK. This ensures that code generated with the standalone toolchain
-          doesn't risk to accidentally depend on a non-stable ABI symbol (e.g. any libgcc.a
-          symbol that changes each time the toolchain used to build the platform is changed)</li>
-
-          <li>Refreshed the EGL and OpenGLES Khronos headers to support more extensions. Note
-          that this does <em>not</em> change the NDK ABIs for the corresponding libraries,
-          because each extension must be probed at runtime by the client application.
-
-            <p>The extensions that are available depend on your actual device and GPU drivers,
-            not the platform version the device runs on. The header changes simply add new
-            constants and types to make it easier to use the extensions when they have been
-            probed with <code>eglGetProcAddress()</code> or <code>glGetProcAddress()</code>. The
-            following list describes the newly supported extensions:</p>

-      <p>This release of the NDK includes support for the x86 ABI and other minor changes.
-      For detailed information describing the changes in this release, read the
-      <code>CHANGES.HTML</code> document included in the NDK package.

-      <dl>
-        <dt>General notes:</dt>
-        <dd>
-          <ul>
-            <li>Adds support for the x86 ABI, which allows you to generate machine code
-            that runs on compatible x86-based Android devices. Major features for x86
-            include x86-specific toolchains, system headers, libraries and
-            debugging support. For all of the details regarding x86 support,
-            see <code>docs/CPU-X86.html</code> in the NDK package.
-
-              <p>By default, code is generated for ARM-based devices, but you can add x86 to your
-              <code>APP_ABI</code> definition in your <code>Application.mk</code> file to build
-              for x86 platforms. For example, the following line instructs <code>ndk-build</code>
-              to build your code for three distinct ABIs:</p>
-
-              <pre>APP_ABI := armeabi armeabi-v7a x86</pre>
-
-              <p>Unless you rely on ARM-based assembly sources, you shouldn't need to touch
-              your <code>Android.mk</code> files to build x86 machine code.</p>
-
-            </li>
-
-            <li>You can build a standalone x86 toolchain using the
-<code>--toolchain=x86-4.4.3</code>
-            option when calling <code>make-standalone-toolchain.sh</code>. See
-            <code>docs/STANDALONE-TOOLCHAIN.html</code> for more details.
-            </li>
-            <li>The new <code>ndk-stack</code> tool lets you translate stack traces in
-            <code>logcat</code> that are generated by native code. The tool translates
-            instruction addresses into a readable format that contains things such
-            as the function, source file, and line number corresponding to each stack frame.
-            For more information and a usage example, see <code>docs/NDK-STACK.html</code>.

-    <p>This release of the NDK does not include any new features compared to r5b. The r5c release
-    addresses the following problems in the r5b release:</p>
-    <dl>
-      <dt>Important bug fixes:</dt>
-      <dd>
-        <ul>
-          <li><code>ndk-build</code>: Fixed a rare bug that appeared when trying to perform parallel
-          builds of debuggable projects.</li>
-
-          <li>Fixed a typo that prevented <code>LOCAL_WHOLE_STATIC_LIBRARIES</code> to work
-          correctly with the new toolchain and added documentation for this in
-          <code>docs/ANDROID-MK.html</code>.</li>
-
-          <li>Fixed a bug where code linked against <code>gnustl_static</code> crashed when run on
-          platform releases older than API level 8 (Android 2.2).</li>
-
-          <li><code>ndk-gdb</code>: Fixed a bug that caused a segmentation fault when debugging
-Android 3.0
-          or newer devices.</li>
-
-          <li><code>&lt;android/input.h&gt;</code>: Two functions that were introduced in API level
-          9 (Android 2.3) were incorrect and are fixed. While this breaks the source API, the
-          binary interface to the system is unchanged. The incorrect functions were missing a
-          <code>history_index</code> parameter, and the correct definitions are shown below:
-<pre>
-float AMotionEvent_getHistoricalRawX(const AInputEvent* motion_event,
-                                           size_t pointer_index,
-                                           size_t history_index);
-
-float AMotionEvent_getHistoricalRawY(const AInputEvent* motion_event,
-                                           size_t pointer_index,
-                                           size_t history_index);
-</pre>
-          </li>
-
-          <li>Updated the C library ARM binary for API level 9 (Android 2.3) to correctly expose at
-          link time new functions that were added in that API level (for example,
-          <code>pthread_rwlock_init</code>).</li>
-
-        </ul>

-
-      <dt>Minor improvements and fixes:</dt>
-      <dd>
-        <ul>
-          <li>Object files are now always linked in the order they appear in
-          <code>LOCAL_SRC_FILES</code>. This was not the case previously because the files were
-          grouped by source extensions instead.</li>
-
-          <li>When <code>import-module</code> fails, it now prints the list of directories that
-          were searched. This is useful to check that the <code>NDK_MODULE_PATH</code> definition
-          used by the build system is correct.</li>
-
-          <li>When <code>import-module</code> succeeds, it now prints the directory where the
-          module was found to the log (visible with <code>NDK_LOG=1</code>).</li>
-
-          <li>Increased the build speed of debuggable applications when there is a very large number
-          of include directories in the project.</li>
-
-          <li><code>ndk-gdb</code>: Better detection of <code>adb shell</code> failures and improved
-          error messages.</li>
-
-          <li><code>&lt;pthread.h&gt;</code>: Fixed the definition of
-          <code>PTHREAD_RWLOCK_INITIALIZER</code> for API level 9 (Android 2.3) and higher.</li>
-
-          <li>Fixed an issue where a module could import itself, resulting in an infinite loop in
-          GNU Make.</li>
-
-          <li>Fixed a bug that caused the build to fail if <code>LOCAL_ARM_NEON</code> was set to
-          true (typo in <code>build/core/build-binary.mk</code>).</li>
-
-          <li>Fixed a bug that prevented the compilation of <code>.s</code> assembly files

-      <p>This release of the NDK does not include any new features compared to r5. The r5b release
-addresses the
-      following problems in the r5 release:
-      </p>
-      <ul>
-    <li>The r5 binaries required glibc 2.11, but the r5b binaries are generated with a special
-    toolchain that targets glibc 2.7 or higher instead. The Linux toolchain binaries now run on
-Ubuntu 8.04 or higher. </li>
-    <li>Fixes a compiler bug in the arm-linux-androideabi-4.4.3 toolchain.
-    The previous binary generated invalid thumb instruction sequences when
-    dealing with signed chars.</li>
-    <li>Adds missing documentation for the
-    "gnustl_static" value for APP_STL, that allows you to link against
-    a static library version of GNU libstdc++. </li> the
-    <li>Fixed the following <code>ndk-build</code> issues:
-      <ul>
-        <li>A bug that created inconsistent dependency files when a
-        compilation error occured on Windows. This prevented a proper build after
-        the error was fixed in the source code.</li>
-        <li>A Cygwin-specific bug where using very short paths for
-        the Android NDK installation or the project path led to the
-        generation of invalid dependency files. This made incremental builds
-        impossible.</li>
-        <li>A typo that prevented the cpufeatures library from working correctly
-        with the new NDK toolchain.</li>
-        <li>Builds in Cygwin are faster by avoiding calls to <code>cygpath -m</code>
-        from GNU Make for every source or object file, which caused problems
-        with very large source trees. In case this doesn't work properly, define
-<code>NDK_USE_CYGPATH=1</code> in your
-        environment to use <code>cygpath -m</code> again.</li>
-        <li>The Cygwin installation now notifies the user of invalid installation paths that
-contain spaces. Previously, an invalid path
-        would output an error that complained about an incorrect version of GNU Make, even if the
-right one was installed.
-      </ul>
-    </li>
-  <li>Fixed a typo that prevented the <code>NDK_MODULE_PATH</code> environment variable from
-working properly when
-  it contained multiple directories separated with a colon. </li>
-  <li>The <code>prebuilt-common.sh</code> script contains fixes to check the compiler for 64-bit
-  generated machine code, instead of relying on the host tag, which
-  allows the 32-bit toolchain to rebuild properly on Snow Leopard. The toolchain rebuild scripts
-now also support
-  using a 32-bit host toolchain.</li>
-  <li>A missing declaration for <code>INET_ADDRSTRLEN</code> was added to
-<code>&lt;netinet/in.h&gt;</code>.</li>
-  <li>Missing declarations for <code>IN6_IS_ADDR_MC_NODELOCAL</code> and
-<code>IN6_IS_ADDR_MC_GLOBAL</code> were added to <code>&lt;netinet/in6.h&gt;</code>.</li>
-  <li>'asm' was replaced with '__asm__' in <code>&lt;asm/byteorder.h&gt;</code> to allow
-compilation with <code>-std=c99</code>.</li>

-      <p>This release of the NDK includes many new APIs, most of which are introduced to
-         support the development of games and similar applications that make extensive use

-         graphics and window management, assets, and storage. Developers can also implement the
-         Android application lifecycle in native code with help from the new
-         {@link android.app.NativeActivity} class. For detailed information describing the changes

-          <ul>
-            <li>Adds support for native activities, which allows you to implement the
-            Android application lifecycle in native code.</li>
-
-            <li>Adds native support for the following:
-
-              <ul>
-
-                <li>Input subsystem (such as the keyboard and touch screen)</li>
-
-                <li>Access to sensor data (accelerometer, compass, gyroscope, etc).</li>
-
-                <li>Event loop APIs to wait for things such as input and sensor events.</li>
-
-                <li>Window and surface subsystem</li>
-
-                <li>Audio APIs based on the OpenSL ES standard that support playback and recording
-                as well as control over platform audio effects</li>
-
-                <li>Access to assets packaged in an <code>.apk</code> file.</li>
-
-              </ul>
-            </li>
-
-            <li>Includes a new toolchain (based on GCC 4.4.3), which generates better code, and can
-also now
-            be used as a standalone cross-compiler, for people who want to build their stuff with
-            <code>./configure &amp;&amp; make</code>. See
-            docs/STANDALONE-TOOLCHAIN.html for the details. The binaries for GCC 4.4.0 are still
-provided,
-            but the 4.2.1 binaries were removed.</li>
-
-            <li>Adds support for prebuilt static and shared libraries (docs/PREBUILTS.html) and
-module
-            exports and imports to make sharing and reuse of third-party modules much easier
-            (docs/IMPORT-MODULE.html explains why).</li>
-
-            <li>Provides a default C++ STL implementation (based on STLport) as a helper module. It
-can be used either
-            as a static or shared library (details and usage examples are in
-sources/android/stlport/README). Prebuilt
-            binaries for STLport (static or shared) and GNU libstdc++ (static only) are also
-provided if you choose to
-            compile against those libraries instead of the default C++ STL implementation.
-            C++ Exceptions and RTTI are not supported in the default STL implementation. For more
-information, see
-            docs/CPLUSPLUS-SUPPORT.HTML.</li>
-
-            <li>Includes improvements to the <code>cpufeatures</code> helper library that improves
-reporting
-            of the CPU type (some devices previously reported ARMv7 CPU when the device really was
-an ARMv6). We
-            recommend developers that use this library to rebuild their applications then
-            upload to Google Play to benefit from the improvements.</li>
-
-            <li>Adds an EGL library that lets you create and manage OpenGL ES textures and
-              services.</li>
-
-            <li>Adds new sample applications, <code>native-plasma</code> and
-<code>native-activity</code>,
-            to demonstrate how to write a native activity.</li>
-
-            <li>Includes many bugfixes and other small improvements; see docs/CHANGES.html for a
-more
-              detailed list of changes.</li>

-          <ul>
-            <li>Provides a simplified build system through the new <code>ndk-build</code> build
-            command.</li>
-
-            <li>Adds support for easy native debugging of generated machine code on production
-            devices through the new <code>ndk-gdb</code> command.</li>
-
-            <li>Adds a new Android-specific ABI for ARM-based CPU architectures,
-            <code>armeabi-v7a</code>. The new ABI extends the existing <code>armeabi</code> ABI to
-            include these CPU instruction set extensions:
-
-              <ul>
-                <li>Thumb-2 instructions</li>
-
-                <li>VFP hardware FPU instructions (VFPv3-D16)</li>
-
-                <li>Optional support for ARM Advanced SIMD (NEON) GCC intrinsics and VFPv3-D32.
-                Supported by devices such as Verizon Droid by Motorola, Google Nexus One, and
-                others.</li>
-              </ul>
-            </li>
-
-            <li>Adds a new <code>cpufeatures</code> static library (with sources) that lets your
-            app detect the host device's CPU features at runtime. Specifically, applications can
-            check for ARMv7-A support, as well as VFPv3-D32 and NEON support, then provide separate
-            code paths as needed.</li>
-
-            <li>Adds a sample application, <code>hello-neon</code>, that illustrates how to use the
-            <code>cpufeatures</code> library to check CPU features and then provide an optimized
-            code path using NEON instrinsics, if supported by the CPU.</li>
-
-            <li>Lets you generate machine code for either or both of the instruction sets supported
-            by the NDK. For example, you can build for both ARMv5 and ARMv7-A architectures at the
-            same time and have everything stored to your application's final
-            <code>.apk</code>.</li>
-
-            <li>To ensure that your applications are available to users only if their devices are
-            capable of running them, Google Play now filters applications based on the
-            instruction set information included in your application &mdash; no action is needed on
-            your part to enable the filtering. Additionally, the Android system itself also checks
-            your application at install time and allows the installation to continue only if the
-            application provides a library that is compiled for the device's CPU architecture.</li>
-
-            <li>Adds support for Android 2.2, including a new stable API for accessing the pixel
-            buffers of {@link android.graphics.Bitmap} objects from native code.</li>

-  <h2 id="Reqs">System and Software Requirements</h2>
-
-  <p>The sections below describe the system and software requirements for using the Android NDK, as
-  well as platform compatibility considerations that affect appplications using libraries produced
-  with the NDK.</p>
-
-  <h4>The Android SDK</h4>
-
-  <ul>
-    <li>A complete Android SDK installation (including all dependencies) is required.</li>
-
-    <li>Android 1.5 SDK or later version is required.</li>
-  </ul>
-
-  <h4>Supported operating systems</h4>
-
-  <ul>
-    <li>Windows XP (32-bit) or Vista (32- or 64-bit)</li>
-
-    <li>Mac OS X 10.4.8 or later (x86 only)</li>
-
-    <li>Linux (32 or 64-bit; Ubuntu 8.04, or other Linux distributions using GLibc 2.7 or
-later)</li>
-  </ul>
-
-  <h4>Required development tools</h4>
-
-  <ul>
-    <li>For all development platforms, GNU Make 3.81 or later is required. Earlier versions of GNU
-    Make might work but have not been tested.</li>
-
-    <li>A recent version of awk (either GNU Awk or Nawk) is also required.</li>
-
-    <li>For Windows, <a href="http://www.cygwin.com">Cygwin</a> 1.7 or higher is required. The NDK
-    will <em>not</em> work with Cygwin 1.5 installations.</li>
-  </ul>
-
-  <h4 id="platform-compat">Android platform compatibility</h4>
-
-  <ul>
-    <li>The native libraries created by the Android NDK can only be used on devices running
-      specific minimum Android platform versions. The minimum required platform version depends on
-      the CPU architecture of the devices you are targeting. The following table details which
-      Android platform versions are compatible with native code developed for specific CPU
-      architectures.
-
-    <table style="margin:1em;">
-      <tr>
-        <th>Native Code CPU Architecture Used</th>
-        <th>Compatible Android Platform(s)</th>
-      </tr>
-
-      <tr>
-        <td>ARM, ARM-NEON</td>
-        <td>Android 1.5 (API Level 3) and higher</td>
-      </tr>
-
-      <tr>
-        <td>x86</td>
-        <td>Android 2.3 (API Level 9) and higher</td>
-      </tr>
-
-      <tr>
-        <td>MIPS</td>
-        <td>Android 2.3 (API Level 9) and higher</td>
-      </tr>
-    </table>
-
-      <p>These requirements mean you can use native libraries produced with the NDK in
-      applications that are deployable to ARM-based devices running Android 1.5 or later. If you are
-      deploying native libraries to x86 and MIPS-based devices, your application must target Android
-      2.3 or later.</p>
-    </li>
-
-    <li>To ensure compatibility, an application using a native library produced with the NDK
-    <em>must</em> declare a <a href="{@docRoot}guide/topics/manifest/uses-sdk-element.html"><code>
-      &lt;uses-sdk&gt;</code></a> element in its manifest file, with an
-      <code>android:minSdkVersion</code> attribute value of "3" or higher. For example:
-
-<pre style="margin:1em;">
-&lt;manifest&gt;
-  &lt;uses-sdk android:minSdkVersion="3" /&gt;
-  ...
-&lt;/manifest&gt;
-</pre>
-    </li>
-
-    <li>If you use this NDK to create a native library that uses the OpenGL ES APIs, the
-    application containing the library can be deployed only to devices running the minimum platform
-    versions described in the table below. To ensure compatibility, make sure that your application
-    declares the proper <code>android:minSdkVersion</code> attribute value, as shown in the
-    following table.</li>
-
-    <li style="list-style: none; display: inline">
-      <table style="margin:1em;">
-        <tr>
-          <th>OpenGL ES Version Used</th>
-
-          <th>Compatible Android Platform(s)</th>
-
-          <th>Required uses-sdk Attribute</th>
-        </tr>
-
-        <tr>
-          <td>OpenGL ES 1.1</td>
-
-          <td>Android 1.6 (API Level 4) and higher</td>
-
-          <td><code>android:minSdkVersion="4"</code></td>
-        </tr>
-
-        <tr>
-          <td>OpenGL ES 2.0</td>
-
-          <td>Android 2.0 (API Level 5) and higher</td>
-
-          <td><code>android:minSdkVersion="5"</code></td>
-        </tr>
-      </table>
-
-      <p>For more information about API Level and its relationship to Android platform versions,
-      see <a href="{@docRoot}guide/topics/manifest/uses-sdk-element.html#ApiLevels">Android API
-Levels</a>.</p>
-    </li>
-
-    <li>Additionally, an application using the OpenGL ES APIs should declare a
-    <code>&lt;uses-feature&gt;</code> element in its manifest, with an
-    <code>android:glEsVersion</code> attribute that specifies the minimum OpenGl ES version
-    required by the application. This ensures that Google Play will show your application only
-    to users whose devices are capable of supporting your application. For example:
-      <pre style="margin:1em;">
-&lt;manifest&gt;
-<!-- Declare that the application uses the OpenGL ES 2.0 API and is designed
-     to run only on devices that support OpenGL ES 2.0 or higher. -->
-  &lt;uses-feature android:glEsVersion="0x00020000" /&gt;
-  ...
-&lt;/manifest&gt;
-</pre>
-
-      <p>For more information, see the <a href=
-
-"{@docRoot}guide/topics/manifest/uses-feature-element.html"><code>&lt;uses-feature&gt;</code></a>
-      documentation.</p>
-    </li>
-
-    <li>If you use this NDK to create a native library that uses the API to access Android {@link
-    android.graphics.Bitmap} pixel buffers or utilizes native activities, the application
-    containing the library can be deployed only to devices running Android 2.2 (API level 8) or
-    higher. To ensure compatibility, make sure that your application declares <code>&lt;uses-sdk
-    android:minSdkVersion="8" /&gt;</code> attribute value in its manifest.</li>

-  <h2 id="Installing">Installing the NDK</h2>
-  <p>Installing the NDK on your development computer is straightforward and involves extracting the
-  NDK from its download package.</p>
-
-  <p>Before you get started make sure that you have downloaded the latest <a href=
-  "{@docRoot}sdk/index.html">Android SDK</a> and upgraded your applications and environment as
-  needed. The NDK is compatible with older platform versions but not older versions of the SDK
-tools.
-  Also, take a moment to review the <a href="#Reqs">System and
-Software Requirements</a>
-  for the NDK, if you haven't already.</p>
-
-  <p>To install the NDK, first download the appropriate package from the table at the top of this
-  page. Then, follow the procedure for your development platform:</p>

-    can move it to any location on your computer. This documentation refers to the NDK directory as
-    <code>&lt;ndk&gt;</code>.
-
-
-  <p>You are now ready to start working with the NDK.</p>
-
-
-<h2 id="GetStarted">Getting Started with the NDK</h2>
-
-<p>Once you've installed the NDK successfully, take a few minutes to read the documentation
-included in the NDK. You can find the documentation in the <code>&lt;ndk&gt;/docs/</code>
-directory. In particular, please read the OVERVIEW.HTML document completely, so that you
-understand the intent of the NDK and how to use it.</p>
-
-<p>If you used a previous version of the NDK, take a moment to review the list of NDK changes in
-the CHANGES.HTML document.</p>
-
-<p>Here's the general outline of how you work with the NDK tools:</p>
-
-<ol>
-  <li>Place your native sources under <code>&lt;project&gt;/jni/...</code></li>
-
-  <li>Create <code>&lt;project&gt;/jni/Android.mk</code> to describe your native sources to the
-  NDK build system</li>
-
-  <li>Optional: Create <code>&lt;project&gt;/jni/Application.mk</code>.</li>
-
-  <li>Build your native code by running the 'ndk-build' script from your project's directory. It
-  is located in the top-level NDK directory:
-    <pre class="no-pretty-print">cd &lt;project&gt;
-&lt;ndk&gt;/ndk-build
-</pre>
-
-    <p>The build tools copy the stripped, shared libraries needed by your application to the
-    proper location in the application's project directory.</p>
-  </li>
-
-  <li>Finally, compile your application using the SDK tools in the usual way. The SDK build tools
-  will package the shared libraries in the application's deployable <code>.apk</code> file.</li>
-</ol>
-
-<p>For complete information on all of the steps listed above, please see the documentation
-included with the NDK package.</p>
-
-
-<h3 id="Using">Using the NDK</h3>
-
-<p>The Android framework provides two ways to use native code:</p>
-
-<ul>
-  <li>Write your application using the Android framework and use JNI to access the APIs provided
-  by the Android NDK. This technique allows you to take advantage of the convenience of the
-  Android framework, but still allows you to write native code when necessary. If you use this
-  approach, your application must target specific, minimum Android platform levels, see <a
-  href="#platform-compat">Android platform compatibility</a> for more information.</li>
-
-  <li>
-    <p>Write a native activity, which allows you to implement the lifecycle callbacks in native
-    code. The Android SDK provides the {@link android.app.NativeActivity} class, which is a
-    convenience class that notifies your
-    native code of any activity lifecycle callbacks (<code>onCreate()</code>,
-<code>onPause()</code>,
-    <code>onResume()</code>, etc). You can implement the callbacks in your native code to handle
-    these events when they occur. Applications that use native activities must be run on Android
-    2.3 (API Level 9) or later.</p>
-
-    <p>You cannot access features such as Services and Content Providers natively, so if you want
-    to use them or any other framework API, you can still write JNI code to do so.</p>
-  </li>
-</ul>
-
-
-
-
-
-  <h2 id="Contents">Contents of the NDK</h2>
-
-  <p>The NDK contains the APIs, documentation, and sample
-  applications that help you write your native code. Specifically:</p>
-
-  <ul>
-    <li>A set of tools and build files used to generate native code libraries from C and C++
-    sources</li>
-
-    <li>A way to embed the corresponding native libraries into an application package file
-    (<code>.apk</code>) that can be deployed on Android devices</li>
-
-    <li>A set of native system headers and libraries that will be supported in all future versions
-    of the Android platform, starting from Android 1.5. Applications that use native activities
-    must be run on Android 2.3 or later.</li>
-
-    <li>Documentation, samples, and tutorials</li>
-  </ul>
-
-  <p>The latest release of the NDK supports the following instruction sets:</p>
-
-  <ul>
-    <li>ARMv5TE, including Thumb-1 instructions (see {@code docs/CPU-ARCH-ABIS.html} for more
-information)</li>
-
-    <li>ARMv7-A, including Thumb-2 and VFPv3-D16 instructions, with optional support for
-    NEON/VFPv3-D32 instructions (see {@code docs/CPU-ARM-NEON.html} for more information)</li>
-
-    <li>x86 instructions (see {@code docs/CPU-X86.html} for more information)</li>
-
-    <li>MIPS instructions (see {@code docs/CPU-MIPS.html} for more information)</li>
-  </ul>
-
-  <p>ARMv5TE machine code will run on all ARM-based Android devices. ARMv7-A will run only on
-  devices such as the Verizon Droid or Google Nexus One that have a compatible CPU. The main
-  difference between the two instruction sets is that ARMv7-A supports hardware FPU, Thumb-2, and
-  NEON instructions. You can target either or both of the instruction sets &mdash; ARMv5TE is the
-  default, but switching to ARMv7-A is as easy as adding a single line to the application's
-  <code>Application.mk</code> file, without needing to change anything else in the file. You can
-also build for
-  both architectures at the same time and have everything stored in the final <code>.apk</code>.
-  Complete information is provided in the CPU-ARCH-ABIS.HTML in the NDK package.</p>
-
-  <p>The NDK provides stable headers for libc (the C library), libm (the Math library), OpenGL ES
-  (3D graphics library), the JNI interface, and other libraries, as listed in the <a href=
-  "#Tools">Development tools</a> section.</p>
-
-
-  <h3 id="Tools">Development tools</h3>
-
-  <p>The NDK includes a set of cross-toolchains (compilers, linkers, etc.) that can generate
-  native ARM binaries on Linux, OS X, and Windows (with Cygwin) platforms.</p>
-
-  <p>It provides a set of system headers for stable native APIs that are guaranteed to be supported
-  in all later releases of the platform:</p>
-
-  <ul>
-    <li>libc (C library) headers</li>
-
-    <li>libm (math library) headers</li>
-
-    <li>JNI interface headers</li>
-
-    <li>libz (Zlib compression) headers</li>
-
-    <li>liblog (Android logging) header</li>
-
-    <li>OpenGL ES 1.1 and OpenGL ES 2.0 (3D graphics libraries) headers</li>
-
-    <li>libjnigraphics (Pixel buffer access) header (for Android 2.2 and above).</li>
-
-    <li>A Minimal set of headers for C++ support</li>
-
-    <li>OpenSL ES native audio libraries</li>
-
-    <li>Android native application APIS</li>
-  </ul>
-
-  <p>The NDK also provides a build system that lets you work efficiently with your sources, without
-  having to handle the toolchain/platform/CPU/ABI details. You create very short build files to
-  describe which sources to compile and which Android application will use them &mdash; the build
-  system compiles the sources and places the shared libraries directly in your application
-  project.</p>
-
-  <p class="caution"><strong>Important:</strong> With the exception of the libraries listed above,
-  native system libraries in the Android platform are <em>not</em> stable and may change in future
-  platform versions. Your applications should <em>only</em> make use of the stable native system
-  libraries provided in this NDK.</p>
-
-
-
-  <h3 id="Docs">Documentation</h3>

-
-<h3 id="Samples">Sample apps</h3>
-
-<p>The NDK includes sample applications that illustrate how to use native code in your Android
-  applications:</p>
-
-  <ul>
-    <li><code>hello-jni</code> &mdash; a simple application that loads a string from a native
-    method implemented in a shared library and then displays it in the application UI.</li>
-
-    <li><code>two-libs</code> &mdash; a simple application that loads a shared library dynamically
-    and calls a native method provided by the library. In this case, the method is implemented in a
-    static library imported by the shared library.</li>
-
-    <li><code>san-angeles</code> &mdash; a simple application that renders 3D graphics through the
-    native OpenGL ES APIs, while managing activity lifecycle with a {@link
-    android.opengl.GLSurfaceView} object.</li>
-
-    <li><code>hello-gl2</code> &mdash; a simple application that renders a triangle using OpenGL ES
-    2.0 vertex and fragment shaders.</li>
-
-    <li><code>hello-neon</code> &mdash; a simple application that shows how to use the
-    <code>cpufeatures</code> library to check CPU capabilities at runtime, then use NEON intrinsics
-    if supported by the CPU. Specifically, the application implements two versions of a tiny
-    benchmark for a FIR filter loop, a C version and a NEON-optimized version for devices that
-    support it.</li>
-
-    <li><code>bitmap-plasma</code> &mdash; a simple application that demonstrates how to access the
-    pixel buffers of Android {@link android.graphics.Bitmap} objects from native code, and uses
-    this to generate an old-school "plasma" effect.</li>
-
-    <li><code>native-activity</code> &mdash; a simple application that demonstrates how to use the
-    native-app-glue static library to create a native activity</li>
-
-    <li><code>native-plasma</code> &mdash; a version of bitmap-plasma implemented with a native
-    activity.</li>
-  </ul>
-
-  <p>For each sample, the NDK includes the corresponding C source code and the necessary Android.mk
-  and Application.mk files. There are located under <code>&lt;ndk&gt;/samples/&lt;name&gt;/</code>
-  and their source code can be found under <code>&lt;ndk&gt;/samples/&lt;name&gt;/jni/</code>.</p>
-
-  <p>You can build the shared libraries for the sample apps by going into
-  <code>&lt;ndk&gt;/samples/&lt;name&gt;/</code> then calling the <code>ndk-build</code> command.
-  The generated shared libraries will be located under
-  <code>&lt;ndk&gt;/samples/&lt;name&gt;/libs/armeabi/</code> for (ARMv5TE machine code) and/or
-  <code>&lt;ndk&gt;/samples/&lt;name&gt;/libs/armeabi-v7a/</code> for (ARMv7 machine code).</p>
-
-  <p>Next, build the sample Android applications that use the shared libraries:</p>
-
-  <ul>
-    <li>If you are developing in Eclipse with ADT, use the New Project Wizard to create a new
-    Android project for each sample, using the "Import from Existing Source" option and importing
-    the source from <code>&lt;ndk&gt;/samples/&lt;name&gt;/</code>. Then, set up an AVD,
-    if necessary, and build/run the application in the emulator.</li>
-
-    <li>If you are developing with Ant, use the <code>android</code> tool to create the build file
-    for each of the sample projects at <code>&lt;ndk&gt;/samples/&lt;name&gt;/</code>.
-    Then set up an AVD, if necessary, build your project in the usual way, and run it in the
-    emulator.</li>
-
-  </ul>
-
-  <p>For more information about developing with the Android SDK tools and what
-  you need to do to create, build, and run your applications, see
-  the <a href="{@docRoot}tools/workflow/index.html">Overview</a>

-
-  <h4 id="hello-jni">Exploring the hello-jni Sample</h4>
-
-  <p>The hello-jni sample is a simple demonstration on how to use JNI from an Android application.
-  The HelloJni activity receives a string from a simple C function and displays it in a
-  TextView.</p>
-
-  <p>The main components of the sample include:</p>
-
-  <ul>
-    <li>The familiar basic structure of an Android application (an <code>AndroidManifest.xml</code>
-    file, a <code>src/</code> and <code>res</code> directories, and a main activity)</li>
-
-    <li>A <code>jni/</code> directory that includes the implemented source file for the native code
-    as well as the Android.mk file</li>
-
-    <li>A <code>tests/</code> directory that contains unit test code.</li>
-  </ul>
-
-  <ol>
-    <li>Create a new project in Eclipse from the existing sample source or use the
-    <code>android</code> tool to update the project so it generates a build.xml file that you can
-    use to build the sample.
-
-      <ul>
-        <li>In Eclipse:
-
-          <ol type="a">
-            <li>Click <strong>File &gt; New Android Project...</strong></li>
-
-            <li>Select the <strong>Create project from existing source</strong> radio button.</li>
-
-            <li>Select any API level above Android 1.5.</li>
-
-            <li>In the <strong>Location</strong> field, click <strong>Browse...</strong> and select
-            the <code>&lt;ndk-root&gt;/samples/hello-jni</code> directory.</li>
-
-            <li>Click <strong>Finish</strong>.</li>
-          </ol>
-        </li>
-
-        <li>On the command line:
-
-          <ol type="a">
-            <li>Change to the <code>&lt;ndk-root&gt;/samples/hello-jni</code> directory.</li>
-
-            <li>Run the following command to generate a build.xml file:
-              <pre class="no-pretty-print">android update project -p . -s</pre>
-            </li>
-          </ol>
-        </li>
-      </ul>
-    </li>
-
-    <li>Compile the native code using the <code>ndk-build</code> command.
-      <pre class="no-pretty-print">
-cd &lt;ndk-root&gt;/samples/hello-jni
-&lt;ndk_root&gt;/ndk-build
-</pre>
-    </li>
-
-    <li>Build and install the application as you would a normal Android application. If you are
-    using Eclipse, run the application to build and install it on a device. If you are using Ant,
-    run the following commands from the project directory:
-      <pre class="no-pretty-print">
-ant debug
-adb install bin/HelloJni-debug.apk
-</pre>
-    </li>
-  </ol>
-
-  <p>When you run the application on the device, the string <code>Hello JNI</code> should appear on
-  your device. You can explore the rest of the samples that are located in the
-  <code>&lt;ndk-root&gt;/samples</code> directory for more examples on how to use the JNI.</p>
-
-
-
-  <h4 id="native-activity">Exploring the native-activity Sample Application</h4>
-
-  <p>The native-activity sample provided with the Android NDK demonstrates how to use the
-  android_native_app_glue static library. This static library makes creating a native activity
-  easier by providing you with an implementation that handles your callbacks in another thread, so
-  you do not have to worry about them blocking your main UI thread. The main parts of the sample
-  are described below:</p>
-
-  <ul>
-    <li>The familiar basic structure of an Android application (an <code>AndroidManifest.xml</code>
-    file, a <code>src/</code> and <code>res</code> directories). The AndroidManifest.xml declares
-    that the application is native and specifies the .so file of the native activity. See {@link
-    android.app.NativeActivity} for the source or see the
-    <code>&lt;ndk_root&gt;/platforms/samples/native-activity/AndroidManifest.xml</code> file.</li>
-
-    <li>A <code>jni/</code> directory contains the native activity, main.c, which uses the
-    <code>android_native_app_glue.h</code> interface to implement the activity. The Android.mk that
-    describes the native module to the build system also exists here.</li>
-  </ul>
-
-  <p>To build this sample application:</p>
-
-  <ol>
-    <li>Create a new project in Eclipse from the existing sample source or use the
-    <code>android</code> tool to update the project so it generates a build.xml file that you can
-    use to build the sample.
-
-      <ul>
-        <li>In Eclipse:
-
-          <ol type="a">
-            <li>Click <strong>File &gt; New Android Project...</strong></li>
-
-            <li>Select the <strong>Create project from existing source</strong> radio button.</li>
-
-            <li>Select any API level above Android 2.3.</li>
-
-            <li>In the <strong>Location</strong> field, click <strong>Browse...</strong> and select
-            the <code>&lt;ndk-root&gt;/samples/native-activity</code> directory.</li>
-
-            <li>Click <strong>Finish</strong>.</li>
-          </ol>
-        </li>
-
-        <li>On the command line:
-
-          <ol type="a">
-            <li>Change to the <code>&lt;ndk-root&gt;/samples/native-activity</code> directory.</li>
-
-            <li>Run the following command to generate a build.xml file:
-              <pre class="no-pretty-print">
-android update project -p . -s
-</pre>
-            </li>
-          </ol>
-        </li>
-      </ul>
-    </li>
-
-    <li>Compile the native code using the <code>ndk-build</code> command.
-      <pre class="no-pretty-print">
-cd &lt;ndk-root&gt;/platforms/samples/android-9/samples/native-activity
-&lt;ndk_root&gt;/ndk-build
-</pre>
-    </li>
-
-    <li>Build and install the application as you would a normal Android application. If you are
-    using Eclipse, run the application to build and install it on a device. If you are using Ant,
-    run the following commands in the project directory, then run the application on the device:
-      <pre class="no-pretty-print">
-ant debug
-adb install bin/NativeActivity-debug.apk
