+ <ul>
+ <ol>
+ <li>Download the appropriate package from this page.</li>
+ <li>Open a terminal window.</li>
+ <li>Go to the directory to which you downloaded the package.</li>
+ <li>Run <code>chmod a+x</code> on the downloaded package.</li>
+ <li>Execute the package. For example:
+ <pre class="no-pretty-print">
+ndk$ chmod a+x android-ndk-r10c-darwin-x86_64.bin
+ndk$ ./android-ndk-r10c-darwin-x86_64.bin

+ <dt>Important changes:</dt>
+ <dd>
+ <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>.
+ These implications do not apply to shared libraries.</li>
+ </ul>
+ </dd>
+ <dl>
+
+
+ <dt>Important bug fixes:</dt>
+ <dd>
+ <ul>
+ <li>Made more fixes related to
+ <a href="https://gcc.gnu.org/ml/gcc-patches/2014-10/msg00906.html">
+ 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.
+ For more information, see this

+ and this
+ <a href="https://sourceware.org/ml/binutils/2014-11/msg00287.html">binutils message</a>.
+ </li>
+
+ <li>Documented a fix to a libc++ <code>sscanf/vsscanf</code> hang that occurred in API level
+ 21. The fix itself had been implemented in r10c.
+ (Issue <a href="http://b.android.com/77988">77988</a>)</li>
+
+ <li>Fixed an AutoFDO (<code>-fauto-profile</code>) crash that occurred with GCC 4.9 when
+ <code>-Os</code> was specified. (Issue <a href="http://b.android.com/77571">77571</a>)</li>

+ </dd>
+
+
+ <dt>Other bug fixes:</dt>
+ <dd>
+ <ul>
+ <li>Made the following header and library fixes:</li>
+ <ul>
+ <li>Added <code>posix_memalign</code> to API level 16. Also, added a prototype in
+ <code>stdlib.h</code> to API levels 16 to 19.
+ (Issue <a href="http://b.android.com/77861">77861</a>)</li>
+ <li>Fixed <code>stdatomic.h</code> so that it includes <code><atomic></code> only for
+ C++11.</li>
+ <li>Modified the following headers for standalone use: <code>sys/user.h</code>, and
+ <code>gl2ext.h</code>, <code>dlext.h</code>, <code>fts.h</code>, <code>sgidefs.h</code>
+ for API level 21.</li>
+ <li>Modified <code>sys/user.h</code> to rename <code>mxcsr_mask</code> as <code>mxcr_mask</code>,
+ and to change the data type for <code>u_ar0</code></li> from <code>unsigned long</code>
+ to </code>struct user_regs_struct*</code>.
+ <li>Changed <code>sysconf()</code> return value type from <code>int</code> to
+ <code>long</code>.</li>
+ </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.
+ (Issue <a href="http://b.android.com/74040">74040</a>)</li>
+ </ul>
+
+ <li>Fixed <code>LOCAL_SRC_FILES</code> in ndk-build to use Windows absolute paths.
+ (Issue <a href="http://b.android.com/74333">74333</a>)</li>
+
+ <li>Removed bash-specific code from ndk-gdb. (Issue <a href="http://b.android.com/73338">73338</a>)</li>

+ dependencies. (Issue <a href="http://b.android.com/41790">41790</a>)</li>
+
+ <li>Fixed a problem that was preventing 64-bit packages from extracting on Ubuntu 14.04 and
+ OS X 10.10 (Yosemite). (Issue <a href="http://b.android.com/78148">78148</a>)</li>

+ <dt>Important changes:</dt>
+ <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>.
+ <li>See Intel's guide to <a href="https://software.intel.com/en-us/blogs/2012/12/12/from-arm-neon-to-intel-mmxsse-automatic-porting-solution-tips-and-tricks"> porting from ARM NEON to Intel SSE.</a></li>
+ </ul>
+ <li>Documented support for <code>_FORTIFY_SOURCE</code> in <code>headers/libs/android-21</code>,
+ which appeared in r10 (when <code>android-21</code> was still called <code>Android-L</code>),
+ but had no documentation.</li>
+ </ul>

+ 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>

+ </p>
+ <div class="toggle-content-toggleme">
+ <dl>
+ <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><tr1/cmath></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 <atomic>.</li>
+ <li>You must add <code>-fno-strict-aliasing</code> if you use <code> <list></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>
+ </dd>
+ <dl>
+
+
+ <dt>Important bug fixes:</dt>
+ <dd>
+ <ul>
+ <li>Fixed libc++ so that it now compiles <code>std::feof</code>, etc. (Issue <a
+href="http://b.android.com/66668">66668</a>).</li>
+ <li>Fixed a Clang 3.3/3.4 atomic library call that caused crashes in some of the libc++
+tests for ABI armeabi.</li>
+ <li>Fixed Clang 3.4 crashes that were occurring on reading precompiled headers. (Issue <a
+href="http://b.android.com/66657">66657</a>).</li>
+ <li>Fixed the Clang 3.3/3.4 <code>-O3</code> assert on:</li>
+ <code>llvm-3.2/llvm/include/llvm/MDBuilder.h:64: llvm::MDNode*
+llvm::MDBuilder::createBranchWeights(llvm::ArrayRef<unsigned int>): Assertion Weights.size() >= 2
+&& "Need at least two branch weights!"</code> (Issue <a href="http://b.android.com/57381">57381</a>).
+ <li>Fixed the following Clang 3.3/3.4 crash:</li>
+ <code>Assertion failed: (!Fn && "cast failed but able to resolve overload expression!!"), function CheckCXXCStyleCast, file
+Volumes/data/ndk-toolchain/src/llvm-3.3/llvm/tools/clang/lib/Sema/SemaCast.cpp, line 2018</code>.

+ </ul>
+ </dd>
+
+ <dt>Other bug fixes:</dt>
+ <dd>
+ <ul>
+ <li>Fixed headers:</li>
+ <ul>
+ <li>Fixed 32-bit <code>ssize_t</code> to be <code>int</code> instead of <code>long
+int</code>.</li>
+ <li>Fixed <code>WCHAR_MIN</code> and <code>WCHAR_MAX</code> so that they they take
+appropriate signs according to the architecture they're running on:</li>
+ <ul>
+ <li>X86/MIPS: signed.
+ <li>ARM: unsigned.
+ <li>To force X86/MIPS to default to unsigned, use
+<code>-D__WCHAR_UNSIGNED__</code>.</li>
+ <li>To force <code>wchar_t</code> to be 16 bits, use <code>-fshort-wchar</code>.</li>
+ </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
+information, see the commit message accompanying AOSP change list
+ <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>
+ <code>include/stdio.h:236:5: warning: conflicts with previous declaration here
+[-Wattributes] int putchar(int);</code> (Change list <a
+href="https://android-review.googlesource.com/#/c/91185">91185</a>).
+ <li>Fixed <code>make-standalone-toolchain.sh --stl=libc++</code> so that it:</li>
+ <ul>
+ <li>Copies <code>cxxabi.h</code>. (Issue <a
+href="http://b.android.com/68001">68001</a>).</li>
+ <li>Runs in directories other than the NDK install directory. (Issues <a
+href="http://b.android.com/67690">67690</a> and <a href="http://b.android.com/68647">68647</a>).</li>
+ </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
+uses <code>strrchr()</code>
+ instead of <code>strchr()</code> to find the library path's true basename.</li>
+ <li>Fixed native-audio's inability to build in debug mode.</li>
+ <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>
+
+ </ul>
+ </dd>
+
+
+ <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
+<code>$NDK/tests/build/b14811006-GOT_PREL-optimization/</code>.</li>
+ <li>Added ARM version for STL gabi++, stlport, and libc++. They now have both it and Thumb
+mode.</li>
+ <li>It is now possible to call the make-standalone-toolchain.sh script with
+<code>--toolchain=x86_64-linux-android-4.9</code>, which is equivalent to
+<code>--toolchain=x86_64-4.9</code>.</li>

+ <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>

+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

+ <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>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>

+ <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>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

+ 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}

+ {@code APP_STL := stlport_static}. (You can still use the {@code -static} option
+ with a standalone toolchain.) Compiling a <em>dynamic</em> executable using

+ <dl>
+ <dt>Important changes:</dt>
+
+ <dd>
+ <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 <tool-path>/bin/clang} and
+ {@code <tool-path>/bin/clang++}. See {@code STANDALONE-TOOLCHAIN.html} for
+ details.</li>
+ </ul>
+ <p class="note"><strong>Note:</strong> This feature is experimental. Please try it and
+ <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>
+ </li>
+ </ul>
+ </dd>
+ </dl>
+
+ <dl>
+ <dt>Important bug fixes:</dt>
+
+ <dd>
+ <ul>
+ <li>Fixed an issue where running {@code make-standalone-toolchain.sh} with root privileges
+ resulted in the stand alone tool chain being inaccessible to some users.
+ (<a href="http://b.android.com/35279">Issue 35279</a>)
+ <ul>
+ <li>All files and executables in the NDK release package are set to have read and
+ execute permissions for all.</li>
+ <li>The ownership/group of {@code libstdc++.a} is now preserved when copied.</li>
+ </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 Windows parallel builds that sometimes failed due to timing issues in the
+ {@code host-mkdir} implementation.
+ (<a href="http://b.android.com/25875">Issue 25875</a>)</li>
+ <li>Fixed GCC 4.4.3 GNU {@code libstdc++} to <em>not</em> merge {@code typeinfo} names by
+ default. For more details, see
+ {@code toolchain repo gcc/gcc-4.4.3/libstdc++-v3/libsupc++/typeinfo}.
+ (<a href="http://b.android.com/22165">Issue 22165</a>)</li>
+ <li>Fixed problem on {@code null} context in GCC 4.6
+ {@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:
+ <ul>
+ <li>Fixed ARM GCC 4.4.3/4.6 {@code g++} to not warn that the <em>mangling of
+ <va_list> 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}.
+ (<a href="http://b.android.com/35616">Issue 35616</a>)
+ </li>
+ <li>Fixed <em>unresolvable R_ARM_THM_CALL relocation</em> error.
+ (<a href="http://b.android.com/35342">Issue 35342</a>)
+ </li>
+ <li>Fixed internal compiler error at {@code reload1.c:3633}, caused by the ARM
+ back-end expecting the wrong operand type when sign-extend from {@code char}.
+ (<a href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50099">GCC Issue 50099</a>)</li>
+ <li>Fixed internal compiler error with negative shift amount.
+ (<a href="http://gcc.gnu.org/ml/gcc-patches/2011-10/msg00594.html">GCC Issue</a>)</li>
+ </ul>
+ </li>
+
+ <li>Fixed {@code -fstack-protector} for X86, which is also the default for the
+ {@code ndk-build} x86 ABI target.</li>
+
+ <li>MIPS-specific fixes:
+ <ul>
+ <li>Fixed {@code STLport} endian-ness by setting {@code _STLP_LITTLE_ENDIAN} to 1 when
+ compiling MIPS {@code libstlport_*}.</li>
+ <li>Fixed GCC {@code __builtin_unreachable} issue when compiling LLVM.
+ (<a href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54369">GCC Issue 54369</a>)</li>
+ <li>Backported fix for {@code cc1} compile process consuming 100% CPU.
+ (<a href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50380">GCC Issue 50380</a>)</li>
+ </ul>
+ </li>
+
+ <li>GNU Debugger-specific fixes:
+ <ul>
+ <li>Disabled Python support in gdb-7.x at build, otherwise the gdb-7.x configure
+ function may pick up whatever Python version is available on the host and build
+ {@code gdb} with a hard-wired dependency on a specific version of Python.
+ (<a href="http://b.android.com/36120">Issue 36120</a>)
+ </li>
+ <li>Fixed {@code ndk-gdb} when {@code APP_ABI} contains {@code all} and matchs none
+ of the known architectures.
+ (<a href="http://b.android.com/35392">Issue 35392</a>)
+ </li>
+ <li>Fixed Windows pathname support, by keeping the {@code :} character if it looks
+ like it could be part of a Windows path starting with a drive letter.
+ (<a href="http://sourceware.org/bugzilla/show_bug.cgi?id=12843">GDB Issue 12843</a>)
+ </li>
+ <li>Fixed adding of hardware breakpoint support for ARM in {@code gdbserver}.
+ (<a href="http://sourceware.org/ml/gdb-patches/2011-09/msg00200.html">GDB Issue</a>)
+ </li>
+ <li>Added fix to only read the current {@code solibs} when the linker is consistent.
+ This change speeds up {@code solib} event handling.
+ (<a href="http://b.android.com/37677">Issue 37677</a>)
+ </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
+ it succeeds.
+ (<a href="https://android-review.googlesource.com/#/c/43563">Change 43563</a>)</li>
+ <li>Fixed an issue where {@code gdb} would not stop on breakpoints placed in
+ {@code dlopen-ed} libraries.
+ (<a href="http://b.android.com/34856">Issue 34856</a>)
+ </li>
+ <li>Fixed {@code SIGILL} in dynamic linker when calling {@code dlopen()}, on system
+ where {@code /system/bin/linker} is stripped of symbols and
+ {@code rtld_db_dlactivity()} is implemented as {@code Thumb}, due to not preserving
+ {@code LSB} of {@code sym_addr}.

+ <dl>
+ <dt>Other bug fixes:</dt>
+
+ <dd>
+ <ul>
+ <li>Fixed NDK headers:
+ <ul>
+ <li>Fixed {@code arch-mips/include/asm/*} code that was incorrectly removed from
+ original kernel. (<a href="https://android-review.googlesource.com/#/c/43335">Change
+ 43335</a>)</li>
+ <li>Replaced struct member data {@code __unused} with {@code __linux_unused} in
+ {@code linux/sysctl.h} and {@code linux/icmp.h} to avoid conflict with
+ {@code #define __unused} in {@code sys/cdefs.h}.</li>
+ <li>Fixed {@code fenv.h} for enclosed C functions with {@code __BEGIN_DECLS} and
+ {@code __END_DECLS}.</li>
+ <li>Removed unimplemented functions in {@code malloc.h}.</li>
+ <li>Fixed {@code stdint.h} defintion of {@code uint64_t} for ANSI compilers.
+ (<a href="http://b.android.com/1952">Issue 1952</a>)</li>
+ <li>Fixed preprocessor macros in {@code <arch>/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
+ {@code ULONG_LONG_MAX} from {@code <pthread.h>} to {@code
+<limits.h>}.</li>
+ </ul>
+ </li>
+ <li>Fixed a buffer overflow in {@code ndk-stack-parser}.</li>
+ <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;
+}
+</pre>
+ </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}.
+ (<a href="https://groups.google.com/d/msg/android-ndk/-/ew0lTWGr1UEJ">More info</a>)</li>
+ </ul>
+ </dd>

+ <dl>
+ <dt>Other changes:</dt>
+
+ <dd>
+ <ul>
+ <li>Removed {@code arch-x86} and {@code arch-mips} headers from
+ {@code platforms/android-[3,4,5,8]}. Those headers were incomplete, since both X86 and
+ MIPS ABIs are only supported at API 9 or higher.</li>
+ <li>Simplified c++ include path in standalone packages, as shown below.
+ (<a href="http://b.android.com/35279">Issue 35279</a>)
+<pre>
+<path>/arm-linux-androideabi/include/c++/4.6.x-google
+ to:
+<path>/include/c++/4.6/
+</pre></li>
+ <li>Fixed {@code ndk-build} to recognize more C++ file extensions by default:
+ {@code .cc .cp .cxx .cpp .CPP .c++ .C}. You may still use {@code LOCAL_CPP_EXTENSION} to
+ overwrite these extension settings.</li>
+ <li>Fixed an issue in {@code samples/san-angeles} that caused a black screen or freeze
+ frame on re-launch.</li>
+ <li>Replaced deprecated APIs in NDK samples.
+ (<a href="http://b.android.com/20017">Issue 20017</a>)
+ <ul>
+ <li>{@code hello-gl2} from android-5 to android-7</li>

+ <li>{@code native-audio} from android-9 to android-10</li>
+ <li>{@code native-plasma} from android-9 to android-10</li>
+ </ul>
+ </li>
+ <li>Added new branding for Android executables with a simpler scheme in section
+ {@code .note.android.ident} (defined in {@code crtbegin_static/dynamic.o}) so that
+ debugging tools can act accordingly. The structure member and values are defined as
+ follows:
+<pre>
+static const struct {
+ int32_t namesz; /* = 8, sizeof ("Android") */
+ int32_t descsz; /* = 1 * sizeof(int32_t) */
+ int32_t type; /* = 1, ABI_NOTETYPE */
+ char name[sizeof "Android"]; /* = "Android" */
+ int32_t android_api; /* = 3, 4, 5, 8, 9, 14 */
+}
+</pre>
+ <p>The previous branding options in section {@code .note.ABI-tag} are deprecated.</p>
+ </li>
+ <li>Added a new script {@code run-tests-all.sh} which calls {@code run-tests.sh} and
+ {@code standalone/run.sh} with various conditions. The script {@code run-tests.sh} runs
+ without the {@code --abi} option, and is enhanced to compile most of the tests for all
+ supported ABIs and run on all attached devices</li>

+ <ul>
+ <li>Added GCC 4.6 toolchain ({@code binutils} 2.21 with {@code gold} and GDB 7.3.x) to
+co-exist with the original GCC 4.4.3 toolchain ({@code binutils} 2.19 and GDB 6.6).

+ 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}

+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>

+ For more details, read {@code docs/ANDROID-ATOMICS.html}.</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>
+ </ul>

+ </dl>
+
+ <dl>
+ <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'},

+ <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>

+ <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><OMXAL/OpenMAXAL.h></code> and
+ <code><OMXAL/OpenMAXAL_Android.h></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>
+ </dd>
+
+ <dt>Important bug fixes</dt>
+
+ <dd>
+ <ul>
+ <li>Imported shared libraries are now installed by default to the target installation
+ location (<code>libs/<abi></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>

+ <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>.

+
+ <li><code>ndk-gdb</code>: Fixed a bug that caused a segmentation fault when debugging
+Android 3.0
+ or newer devices.</li>
+
+ <li><code><android/input.h></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:

+
+ <dt>Minor improvements and fixes:</dt>
+ <dd>
+ <ul>
+ <li>Object files are now always linked in the order they appear in

+ 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><pthread.h></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>

+ </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><netinet/in.h></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><netinet/in6.h></code>.</li>

+
+ <li>Input subsystem (such as the keyboard and touch screen)</li>
+
+ <li>Access to sensor data (accelerometer, compass, gyroscope, etc).</li>
+

+ 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 && 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>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

+ capable of running them, Google Play now 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.</li>

+
+<p>The NDK is not appropriate for most novice Android programmers, and has little value for many

-<li>Update your <code>PATH</code> environment variable with the location of the directory that
-contains the NDK.</li>
-</ol>
-
-
-<h2 id="configure">Configuring Eclipse</h2>
-<p>Eclipse must know where the NDK is in order to use it when building your app. Follow these steps
-to set the location of the NDK.</p>
-<ol type="1">
-<li>Launch Eclipse, which is installed as part of the Android SDK.</li>
-<li>Open <b>Window</b> > <b>Preferences</b>.</li>
-<li>In the pane on the left side of the <i>Preferences</i> window, select <i>Android</i>.

-<li>Import the hello-jni sample from <code><ndk>/samples/</code>, as you would any other Android
-project.</li>
-<li>In the <i>Project Explorer</i> pane, right-click the project name (<i>HelloJni</i>). A
-context menu appears.</li>
-<li>From the context menu, select <b>Android Tools</b> > <b>Add Native Support</b>. The
-<i>Add Android Native Support</i> window appears.</li>
-<li>Accept the default library name (“hello-jni”), and click <b>Finish</b>.</li>

-</ol>
-<h3>Command line</h3>
-<p>Follow these steps to build from the command line:</p>
-<ol type="1">
-<li>Change to the root directory of your project.</li>
-<li>Execute ndk-build to build the native component of your app. do this by
-typing <code>ndk-build</code> at the command prompt.</li>
-<li>Build and install your project as you would a regular Android app written in Java. For more
-information, see

+ 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'
+apply plugin: '<strong>com.android.databinding</strong>'
+</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><?</em><strong>xml version="1.0" encoding="utf-8"</strong><em>?>
+</em><<strong>layout xmlns:android="http://schemas.android.com/apk/res/android"</strong>>
+ <<strong>data</strong>>
+ <<strong>variable name="user" type="com.example.User"</strong>/>
+ </<strong>data</strong>>
+ <<strong>LinearLayout
+ android:orientation="vertical"
+ android:layout_width="match_parent"
+ android:layout_height="match_parent"</strong>>
+ <<strong>TextView android:layout_width="wrap_content"
+ android:layout_height="wrap_content"
+ android:text="@{user.firstName}"</strong>/>
+ <<strong>TextView android:layout_width="wrap_content"
+ android:layout_height="wrap_content"
+ android:text="@{user.lastName}"</strong>/>
+ </<strong>LinearLayout</strong>>
+</<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>
+<<strong>variable name="user" type="com.example.User"</strong>/>
+</pre>
+<p>
+ Expressions within the layout are written in the attribute properties using
+ the “<code>@{}</code>” syntax. Here, the TextView’s text is set to the
+ firstName property of user:
+</p>
+
+<pre>
+<<strong>TextView android:layout_width="wrap_content"
+ android:layout_height="wrap_content"
+ android:text="@{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>
+<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>@{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>
+@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>
+<<strong>data</strong>>
+ <<strong>import type="android.view.View"</strong>/>
+</<strong>data</strong>>
+</pre>
+<p>
+ Now, View may be used within your binding expression:
+</p>
+
+<pre>
+<<strong>TextView
+ android:text="@{user.lastName}"
+ android:layout_width="wrap_content"
+ android:layout_height="wrap_content"
+ android:visibility="@{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>
+<<strong>import type="android.view.View"</strong>/>
+<<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>
+<<strong>data</strong>>
+ <<strong>import type="com.example.User"</strong>/>
+ <<strong>import type="java.util.List"</strong>/>
+ <<strong>variable name="user" type="User"</strong>/>
+ <<strong>variable name="userList" type="List&lt;User>"</strong>/>
+ </<strong>data</strong>>
+</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>
+<<strong>TextView
+ android:text="@{((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>
+<<strong>data</strong>>
+ <<strong>import type="com.example.MyStringUtils"</strong>/>
+ <<strong>variable name="user" type="com.example.User"</strong>/>
+</<strong>data</strong>>
+…
+<<strong>TextView
+ android:text="@{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>
+<<strong>data</strong>>
+ <<strong>import type="android.graphics.drawable.Drawable"</strong>/>
+ <<strong>variable name="user" type="com.example.User"</strong>/>
+ <<strong>variable name="image" type="Drawable"</strong>/>
+ <<strong>variable name="note" type="String"</strong>/>

+<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 — <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>
+<<strong>data class="ContactItem"</strong>>
+ ...
+</<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>
+<<strong>data class=".ContactItem"</strong>>
+ ...
+</<strong>data</strong>>
+</pre>
+<p>
+ In this case, <code>ContactItem</code> is generated in the module package
+ directly. Any package may be used if the full package is provided:
+</p>
+
+<pre>
+<<strong>data class="com.example.ContactItem"</strong>>
+ ...
+</<strong>data</strong>>
+</pre>
+<h3 id="includes">

+ 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>;
+ @Bindable
+ <strong>public </strong>String getFirstName() {
+ <strong>return this</strong>.<strong>firstName</strong>;
+ }
+ @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<String> <strong>firstName </strong>=
+ <strong>new </strong>ObservableField<>();
+ <strong>public final </strong>ObservableField<String> <strong>lastName </strong>=
+ <strong>new </strong>ObservableField<>();
+ <strong>public final </strong>ObservableInt <strong>age </strong>= <strong>new </strong>ObservableInt();
+}
+</pre>
+<p>
+ That'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<String, Object> user = <strong>new </strong>ObservableArrayMap<>();
+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>
+<<strong>data</strong>>
+ <<strong>import type="android.databinding.ObservableMap"</strong>/>
+ <<strong>variable name="user" type="ObservableMap&lt;String, Object>"</strong>/>
+</<strong>data</strong>>
+…
+<<strong>TextView
+ android:text='@{user["lastName"]}'
+ android:layout_width="wrap_content"
+ android:layout_height="wrap_content"</strong>/>
+<<strong>TextView
+ android:text='@{String.valueOf(1 + (Integer)user["age"])}'
+ android:layout_width="wrap_content"
+ android:layout_height="wrap_content"</strong>/>
+</pre>
+<p>
+ ObservableArrayList is useful when the key is an integer:
+</p>
+
+<pre>
+ObservableArrayList<Object> user = <strong>new </strong>ObservableArrayList<>();
+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>
+<<strong>data</strong>>
+ <<strong>import type="android.databinding.ObservableList"</strong>/>
+ <<strong>import type="com.example.my.app.Fields"</strong>/>
+ <<strong>variable name="user" type="ObservableList&lt;Object>"</strong>/>
+</<strong>data</strong>>
+…
+<<strong>TextView
+ android:text='@{user[Fields.LAST_NAME]}'
+ android:layout_width="wrap_content"
+ android:layout_height="wrap_content"</strong>/>
+<<strong>TextView
+ android:text='@{String.valueOf(1 + (Integer)user[Fields.AGE])}'
+ 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 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>
+<<strong>layout xmlns:android="http://schemas.android.com/apk/res/android"</strong>>
+ <<strong>data</strong>>
+ <<strong>variable name="user" type="com.example.User"</strong>/>
+ </<strong>data</strong>>
+ <<strong>LinearLayout
+ android:orientation="vertical"
+ android:layout_width="match_parent"
+ android:layout_height="match_parent"</strong>>
+ <<strong>TextView android:layout_width="wrap_content"
+ android:layout_height="wrap_content"
+ android:text="@{user.firstName}"</strong>
+ <strong>android:id="@+id/firstName"</strong>/>
+ <<strong>TextView android:layout_width="wrap_content"
+ android:layout_height="wrap_content"
+ android:text="@{user.lastName}"</strong>
+ <strong>android:id="@+id/lastName"</strong>/>
+ </<strong>LinearLayout</strong>>
+</<strong>layout</strong>>
+</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>
+<<strong>data</strong>>
+ <<strong>import type="android.graphics.drawable.Drawable"</strong>/>
+ <<strong>variable name="user" type="com.example.User"</strong>/>
+ <<strong>variable name="image" type="Drawable"</strong>/>
+ <<strong>variable name="note" type="String"</strong>/>
+</<strong>data</strong>>
+</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'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't be known. For example, a
+ RecyclerView Adapter operating against arbitrary layouts won'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'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't have any
+ attributes, but plenty of setters. You can use the automatic setters to use
+ one of these.
+</p>
+
+<pre>
+<android.support.v4.widget.<strong>DrawerLayout
+ android:layout_width="wrap_content"
+ android:layout_height="wrap_content"
+ app:scrimColor="@{@color/scrim}"
+ app:drawerListener="@{fragment.drawerListener}"/></strong>
+</pre>
+<h3 id="renamed_setters">
+ Renamed Setters
+</h3>
+
+<p>
+ Some attributes have setters that don'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>
+@BindingMethods({
+ @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>
+
+@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>
+@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>
+<ImageView app:imageUrl=“@{venue.imageUrl}”
+app:error=“@{@drawable/venueError}”/>
+</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>

+ 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>
+<<strong>TextView
+ android:text='@{userMap["lastName"]}'
+ android:layout_width="wrap_content"
+ android:layout_height="wrap_content"</strong>/>
+</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>
+<<strong>View
+ android:background="@{isError ? @color/red : @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>
+@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>
+<<strong>View
+ android:background="@{isError ? @drawable/error : @color/white}"
+ android:layout_width="wrap_content"
+ android:layout_height="wrap_content"</strong>/>
+</pre>

<p>Before downloading the NDK, you should understand that <strong>the NDK
will not benefit most apps</strong>. As a developer, you need to balance its benefits
against its drawbacks. Notably, using native code on Android
generally does not result in a noticable performance improvement,
but it always increases your app complexity. In general, you should only use the NDK

- <dt>Important changes:</dt>
- <dd>
- <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

- 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>

- <dl>
- <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><tr1/cmath></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 <atomic>.</li>
- <li>You must add <code>-fno-strict-aliasing</code> if you use <code> <list></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>
- </dd>
- <dl>
-
-
- <dt>Important bug fixes:</dt>
- <dd>
- <ul>
- <li>Fixed libc++ so that it now compiles <code>std::feof</code>, etc. (Issue <a
-href="http://b.android.com/66668">66668</a>).</li>
- <li>Fixed a Clang 3.3/3.4 atomic library call that caused crashes in some of the libc++
-tests for ABI armeabi.</li>
- <li>Fixed Clang 3.4 crashes that were occurring on reading precompiled headers. (Issue <a
-href="http://b.android.com/66657">66657</a>).</li>
- <li>Fixed the Clang 3.3/3.4 <code>-O3</code> assert on:</li>
- <code>llvm-3.2/llvm/include/llvm/MDBuilder.h:64: llvm::MDNode*
-llvm::MDBuilder::createBranchWeights(llvm::ArrayRef<unsigned int>): Assertion Weights.size() >= 2
-&& "Need at least two branch weights!"</code> (Issue <a href="http://b.android.com/57381">57381</a>).
- <li>Fixed the following Clang 3.3/3.4 crash:</li>
- <code>Assertion failed: (!Fn && "cast failed but able to resolve overload expression!!"), function CheckCXXCStyleCast, file
-Volumes/data/ndk-toolchain/src/llvm-3.3/llvm/tools/clang/lib/Sema/SemaCast.cpp, line 2018</code>.
-(Issue <a href="http://b.android.com/66950">66950</a>).
- </ul>
- </dd>
-
- <dt>Other bug fixes:</dt>
- <dd>
- <ul>
- <li>Fixed headers:</li>
- <ul>
- <li>Fixed 32-bit <code>ssize_t</code> to be <code>int</code> instead of <code>long
-int</code>.</li>
- <li>Fixed <code>WCHAR_MIN</code> and <code>WCHAR_MAX</code> so that they they take
-appropriate signs according to the architecture they're running on:</li>
- <ul>
- <li>X86/MIPS: signed.
- <li>ARM: unsigned.
- <li>To force X86/MIPS to default to unsigned, use
-<code>-D__WCHAR_UNSIGNED__</code>.</li>
- <li>To force <code>wchar_t</code> to be 16 bits, use <code>-fshort-wchar</code>.</li>
- </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
-information, see the commit message accompanying AOSP change list
- <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>
- <code>include/stdio.h:236:5: warning: conflicts with previous declaration here
-[-Wattributes] int putchar(int);</code> (Change list <a
-href="https://android-review.googlesource.com/#/c/91185">91185</a>).
- <li>Fixed <code>make-standalone-toolchain.sh --stl=libc++</code> so that it:</li>
- <ul>
- <li>Copies <code>cxxabi.h</code>. (Issue <a
-href="http://b.android.com/68001">68001</a>).</li>
- <li>Runs in directories other than the NDK install directory. (Issues <a
-href="http://b.android.com/67690">67690</a> and <a href="http://b.android.com/68647">68647</a>).</li>
- </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
-uses <code>strrchr()</code>
- instead of <code>strchr()</code> to find the library path's true basename.</li>
- <li>Fixed native-audio's inability to build in debug mode.</li>
- <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>
-
- </ul>
- </dd>
-
-
- <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
-<code>$NDK/tests/build/b14811006-GOT_PREL-optimization/</code>.</li>
- <li>Added ARM version for STL gabi++, stlport, and libc++. They now have both it and Thumb
-mode.</li>
- <li>It is now possible to call the make-standalone-toolchain.sh script with
-<code>--toolchain=x86_64-linux-android-4.9</code>, which is equivalent to
-<code>--toolchain=x86_64-4.9</code>.</li>

- <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>

- <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>,

- (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

-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>

-<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>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

- 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

- <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>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>
- <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>

- linker is the default where available, so you must explicitly enable it. For more
- information, see {@code CHANGES.HTML}.</li>
- <li>Updated ndk-build to use topological sort for module dependencies, which means the
- build automatically sorts out the order of libraries specified in
- {@code LOCAL_STATIC_LIBRARIES}, {@code LOCAL_WHOLE_STATIC_LIBRARIES} and
- {@code LOCAL_SHARED_LIBRARIES}. For more information, see {@code CHANGES.HTML}.

- <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>
- <p class="note">
- <strong>Note:</strong> This feature is experimental. Please try it and
- <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
- {@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>
- </ul>
- For more information, see {@code CPLUSPLUS-SUPPORT.html}.

- <a href="http://code.google.com/p/android/issues/list">report any issues</a>.</p>
- </li>
- <li>Added a {@code -mstack-protector-guard=} option for x86 to choose between a
- <em>global</em> default path which is compatible with older Android C library (bionic)
- and a new <em>tls</em> path (%gs:20) for {@code -fstack-protector},

-
- <p class="note">
- <strong>Note:</strong> The {@code -mstack-protector-guard} setting itself does not

- <li>Fixed debug builds with Clang so that non-void functions now raise a {@code SIGILL}
- signal for paths without a return statement.</li>
- <li>Updated {@code make-standalone-toolchain.sh} to accept the suffix {@code -clang3.1}

- <dl>
- <dt>Important changes:</dt>
-
- <dd>
- <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 <tool-path>/bin/clang} and
- {@code <tool-path>/bin/clang++}. See {@code STANDALONE-TOOLCHAIN.html} for
- details.</li>
- </ul>
- <p class="note"><strong>Note:</strong> This feature is experimental. Please try it and
- <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>
- </li>
- </ul>
- </dd>
- </dl>
-
- <dl>
- <dt>Important bug fixes:</dt>
-
- <dd>
- <ul>
- <li>Fixed an issue where running {@code make-standalone-toolchain.sh} with root privileges
- resulted in the stand alone tool chain being inaccessible to some users.
- (<a href="http://b.android.com/35279">Issue 35279</a>)
- <ul>
- <li>All files and executables in the NDK release package are set to have read and
- execute permissions for all.</li>
- <li>The ownership/group of {@code libstdc++.a} is now preserved when copied.</li>
- </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 Windows parallel builds that sometimes failed due to timing issues in the
- {@code host-mkdir} implementation.
- (<a href="http://b.android.com/25875">Issue 25875</a>)</li>
- <li>Fixed GCC 4.4.3 GNU {@code libstdc++} to <em>not</em> merge {@code typeinfo} names by
- default. For more details, see
- {@code toolchain repo gcc/gcc-4.4.3/libstdc++-v3/libsupc++/typeinfo}.
- (<a href="http://b.android.com/22165">Issue 22165</a>)</li>
- <li>Fixed problem on {@code null} context in GCC 4.6
- {@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:
- <ul>
- <li>Fixed ARM GCC 4.4.3/4.6 {@code g++} to not warn that the <em>mangling of
- <va_list> 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}.
- (<a href="http://b.android.com/35616">Issue 35616</a>)
- </li>
- <li>Fixed <em>unresolvable R_ARM_THM_CALL relocation</em> error.
- (<a href="http://b.android.com/35342">Issue 35342</a>)
- </li>
- <li>Fixed internal compiler error at {@code reload1.c:3633}, caused by the ARM
- back-end expecting the wrong operand type when sign-extend from {@code char}.
- (<a href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50099">GCC Issue 50099</a>)</li>
- <li>Fixed internal compiler error with negative shift amount.
- (<a href="http://gcc.gnu.org/ml/gcc-patches/2011-10/msg00594.html">GCC Issue</a>)</li>
- </ul>
- </li>
-
- <li>Fixed {@code -fstack-protector} for X86, which is also the default for the
- {@code ndk-build} x86 ABI target.</li>
-
- <li>MIPS-specific fixes:
- <ul>
- <li>Fixed {@code STLport} endian-ness by setting {@code _STLP_LITTLE_ENDIAN} to 1 when
- compiling MIPS {@code libstlport_*}.</li>
- <li>Fixed GCC {@code __builtin_unreachable} issue when compiling LLVM.
- (<a href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54369">GCC Issue 54369</a>)</li>
- <li>Backported fix for {@code cc1} compile process consuming 100% CPU.
- (<a href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50380">GCC Issue 50380</a>)</li>
- </ul>
- </li>
-
- <li>GNU Debugger-specific fixes:
- <ul>
- <li>Disabled Python support in gdb-7.x at build, otherwise the gdb-7.x configure
- function may pick up whatever Python version is available on the host and build
- {@code gdb} with a hard-wired dependency on a specific version of Python.
- (<a href="http://b.android.com/36120">Issue 36120</a>)
- </li>
- <li>Fixed {@code ndk-gdb} when {@code APP_ABI} contains {@code all} and matchs none
- of the known architectures.
- (<a href="http://b.android.com/35392">Issue 35392</a>)
- </li>
- <li>Fixed Windows pathname support, by keeping the {@code :} character if it looks
- like it could be part of a Windows path starting with a drive letter.
- (<a href="http://sourceware.org/bugzilla/show_bug.cgi?id=12843">GDB Issue 12843</a>)
- </li>
- <li>Fixed adding of hardware breakpoint support for ARM in {@code gdbserver}.
- (<a href="http://sourceware.org/ml/gdb-patches/2011-09/msg00200.html">GDB Issue</a>)
- </li>
- <li>Added fix to only read the current {@code solibs} when the linker is consistent.
- This change speeds up {@code solib} event handling.
- (<a href="http://b.android.com/37677">Issue 37677</a>)
- </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
- it succeeds.
- (<a href="https://android-review.googlesource.com/#/c/43563">Change 43563</a>)</li>
- <li>Fixed an issue where {@code gdb} would not stop on breakpoints placed in
- {@code dlopen-ed} libraries.
- (<a href="http://b.android.com/34856">Issue 34856</a>)
- </li>
- <li>Fixed {@code SIGILL} in dynamic linker when calling {@code dlopen()}, on system
- where {@code /system/bin/linker} is stripped of symbols and
- {@code rtld_db_dlactivity()} is implemented as {@code Thumb}, due to not preserving
- {@code LSB} of {@code sym_addr}.

- <dt>Other bug fixes:</dt>
-
- <dd>
- <ul>
- <li>Fixed NDK headers:
- <ul>
- <li>Fixed {@code arch-mips/include/asm/*} code that was incorrectly removed from
- original kernel. (<a href="https://android-review.googlesource.com/#/c/43335">Change
- 43335</a>)</li>
- <li>Replaced struct member data {@code __unused} with {@code __linux_unused} in
- {@code linux/sysctl.h} and {@code linux/icmp.h} to avoid conflict with
- {@code #define __unused} in {@code sys/cdefs.h}.</li>
- <li>Fixed {@code fenv.h} for enclosed C functions with {@code __BEGIN_DECLS} and
- {@code __END_DECLS}.</li>
- <li>Removed unimplemented functions in {@code malloc.h}.</li>
- <li>Fixed {@code stdint.h} defintion of {@code uint64_t} for ANSI compilers.
- (<a href="http://b.android.com/1952">Issue 1952</a>)</li>
- <li>Fixed preprocessor macros in {@code <arch>/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
- {@code ULONG_LONG_MAX} from {@code <pthread.h>} to {@code
-<limits.h>}.</li>
- </ul>
- </li>
- <li>Fixed a buffer overflow in {@code ndk-stack-parser}.</li>
- <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;
-}
-</pre>
- </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}.

-
- <dd>
- <ul>
- <li>Removed {@code arch-x86} and {@code arch-mips} headers from
- {@code platforms/android-[3,4,5,8]}. Those headers were incomplete, since both X86 and
- MIPS ABIs are only supported at API 9 or higher.</li>
- <li>Simplified c++ include path in standalone packages, as shown below.
- (<a href="http://b.android.com/35279">Issue 35279</a>)
-<pre>
-<path>/arm-linux-androideabi/include/c++/4.6.x-google
- to:
-<path>/include/c++/4.6/
-</pre></li>
- <li>Fixed {@code ndk-build} to recognize more C++ file extensions by default:
- {@code .cc .cp .cxx .cpp .CPP .c++ .C}. You may still use {@code LOCAL_CPP_EXTENSION} to
- overwrite these extension settings.</li>
- <li>Fixed an issue in {@code samples/san-angeles} that caused a black screen or freeze
- frame on re-launch.</li>
- <li>Replaced deprecated APIs in NDK samples.
- (<a href="http://b.android.com/20017">Issue 20017</a>)
- <ul>
- <li>{@code hello-gl2} from android-5 to android-7</li>

- <li>{@code native-audio} from android-9 to android-10</li>
- <li>{@code native-plasma} from android-9 to android-10</li>
- </ul>
- </li>
- <li>Added new branding for Android executables with a simpler scheme in section
- {@code .note.android.ident} (defined in {@code crtbegin_static/dynamic.o}) so that
- debugging tools can act accordingly. The structure member and values are defined as
- follows:
-<pre>
-static const struct {
- int32_t namesz; /* = 8, sizeof ("Android") */
- int32_t descsz; /* = 1 * sizeof(int32_t) */
- int32_t type; /* = 1, ABI_NOTETYPE */
- char name[sizeof "Android"]; /* = "Android" */
- int32_t android_api; /* = 3, 4, 5, 8, 9, 14 */
-}
-</pre>
- <p>The previous branding options in section {@code .note.ABI-tag} are deprecated.</p>
- </li>
- <li>Added a new script {@code run-tests-all.sh} which calls {@code run-tests.sh} and
- {@code standalone/run.sh} with various conditions. The script {@code run-tests.sh} runs
- without the {@code --abi} option, and is enhanced to compile most of the tests for all
- supported ABIs and run on all attached devices</li>

- <dd>
- <ul>
- <li>Added GCC 4.6 toolchain ({@code binutils} 2.21 with {@code gold} and GDB 7.3.x) to
-co-exist with the original GCC 4.4.3 toolchain ({@code binutils} 2.19 and GDB 6.6).
- <ul>
- <li>GCC 4.6 is now the default toolchain. You may set {@code

- <li>Support for the {@code gold} linker is only available for ARM and x86
-architectures on Linux and Mac OS hosts. This support is disabled by default. Add {@code
-LOCAL_LDLIBS += -fuse-ld=gold} in {@code Android.mk} to enable it.</li>
- <li>Programs compiled with {@code -fPIE} require the new {@code GDB} for debugging,
-including binaries in Android 4.1 (API Level 16) system images.</li>
- <li>The {@code binutils} 2.21 {@code ld} tool contains back-ported fixes from
-version 2.22:

- <li>Fixed {@code ld --gc-sections}, which incorrectly retains zombie references to
-external libraries. (<a href="http://sourceware.org/bugzilla/show_bug.cgi?id=13177">more
-info</a>).</li>
- <li>Fixed ARM {@code strip} command to preserve the original {@code p_align} and

- </li>
-
- <li>Updated build options to enable the Never eXecute (NX) bit and {@code relro}/{@code
-bind_now} protections by default:
- <ul>
- <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

-
- <dd>
- <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>

- <dl>
- <dt>Important bug fixes:</dt>
-
- <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>
- </ul>
- </dd>
- </dl>
-
- <dl>
- <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><OMXAL/OpenMAXAL.h></code> and
- <code><OMXAL/OpenMAXAL_Android.h></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>
- </dd>
-
- <dt>Important bug fixes</dt>
-
- <dd>
- <ul>
- <li>Imported shared libraries are now installed by default to the target installation
- location (<code>libs/<abi></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>

- <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>.
- </li>
- </ul>

- <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><android/input.h></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>
- </dd>
-
- <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><pthread.h></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
- (<code>.S</code> files were okay).</li>

- <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><netinet/in.h></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><netinet/in6.h></code>.</li>
- <li>'asm' was replaced with '__asm__' in <code><asm/byteorder.h></code> to allow

- <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
- of native code. Using the APIs, developers have direct native access to events, audio,
- 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

- <dd>
- <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 && 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>

- 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 — 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>
- <uses-sdk></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;">
-<manifest>
- <uses-sdk android:minSdkVersion="3" />
- ...
-</manifest>
-</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><uses-feature></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;">
-<manifest>
-<!-- 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. -->
- <uses-feature android:glEsVersion="0x00020000" />
- ...
-</manifest>
-</pre>

- <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>
- <ul>
- <li>On Linux and Mac OS X (Darwin):
- <ul>
- <ol>
- <li>Download the appropriate package from this page.</li>
- <li>Open a terminal window.</li>
- <li>Go to the directory to which you downloaded the package.</li>
- <li>Run <code>chmod a+x</code> on the downloaded package.</li>
- <li>Execute the package. For example:</li>
- <pre>
-ndk$ chmod a+x android-ndk-r10c-darwin-x86_64.bin
-ndk$ ./android-ndk-r10c-darwin-x86_64.bin
- </pre>
- <p>The folder containing the NDK extracts itself.</p>
- <p>Note that you can also use a program like 7z to extract the package.</p>
- </ol>
- </ul>
- <li>On Windows:</li>
- <ul>
- <ol>
- <li>Download the appropriate package from this page.</li>
- <li>Navigate to the folder to which you downloaded the package.</li>
- <li>Double-click the downloaded file. The folder containing the NDK extracts itself.</li>
- </ol>
- </ul>
- </ul>When uncompressed, the NDK files are contained in a directory called
- <code>android-ndk-<version></code>. You can rename the NDK directory if necessary and you
- can move it to any location on your computer. This documentation refers to the NDK directory as
- <code><ndk></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><ndk>/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><project>/jni/...</code></li>
-
- <li>Create <code><project>/jni/Android.mk</code> to describe your native sources to the
- NDK build system</li>
-
- <li>Optional: Create <code><project>/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 <project>
-<ndk>/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 — 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 — 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> — 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> — 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> — 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> — a simple application that renders a triangle using OpenGL ES
- 2.0 vertex and fragment shaders.</li>
-
- <li><code>hello-neon</code> — 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> — 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> — 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> — 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><ndk>/samples/<name>/</code>
- and their source code can be found under <code><ndk>/samples/<name>/jni/</code>.</p>
-
- <p>You can build the shared libraries for the sample apps by going into
- <code><ndk>/samples/<name>/</code> then calling the <code>ndk-build</code> command.
- The generated shared libraries will be located under
- <code><ndk>/samples/<name>/libs/armeabi/</code> for (ARMv5TE machine code) and/or
- <code><ndk>/samples/<name>/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><ndk>/samples/<name>/</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><ndk>/samples/<name>/</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>
- section for developing on Android.</p>
-
-
-
- <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 > 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><ndk-root>/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><ndk-root>/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 <ndk-root>/samples/hello-jni
-<ndk_root>/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><ndk-root>/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><ndk_root>/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 > 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><ndk-root>/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><ndk-root>/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 <ndk-root>/platforms/samples/android-9/samples/native-activity
-<ndk_root>/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
