| Android NDK, Revision 7b</a> <em>(February 2012)</em> |
| |
| <div class="toggleme"> |
| <p>This release of the NDK includes fixes for native Windows builds, Cygwin and many other |
| improvements:</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> |

| Android NDK, Revision 7</a> <em>(November 2011)</em> |
| |
| <div class="toggleme"> |
| <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> |

| Android NDK, Revision 6</a> <em>(July 2011)</em> |
| |
| <div class="toggleme"> |
| <p>This release of the NDK includes support for the x86 ABI and other minor changes. |
| For detailed information describing the changes in this release, read the |
| <code>CHANGES.HTML</code> document included in the NDK package. |
| </p> |
| <dl> |
| <dt>General notes:</dt> |
| <dd> |
| <ul> |
| <li>Adds support for the x86 ABI, which allows you to generate machine code |
| that runs on compatible x86-based Android devices. Major features for x86 |
| include x86-specific toolchains, system headers, libraries and |
| debugging support. For all of the details regarding x86 support, |
| see <code>docs/CPU-X86.html</code> in the NDK package. |
| |
| <p>By default, code is generated for ARM-based devices, but you can add x86 to your |
| <code>APP_ABI</code> definition in your <code>Application.mk</code> file to build |
| for x86 platforms. For example, the following line instructs <code>ndk-build</code> |
| to build your code for three distinct ABIs:</p> |
| |
| <pre>APP_ABI := armeabi armeabi-v7a x86</pre> |
| |
| <p>Unless you rely on ARM-based assembly sources, you shouldn't need to touch |
| your <code>Android.mk</code> files to build x86 machine code.</p> |
| |
| </li> |
| |
| <li>You can build a standalone x86 toolchain using the <code>--toolchain=x86-4.4.3</code> |
| option when calling <code>make-standalone-toolchain.sh</code>. See |
| <code>docs/STANDALONE-TOOLCHAIN.html</code> for more details. |
| </li> |
| <li>The new <code>ndk-stack</code> tool lets you translate stack traces in |
| <code>logcat</code> that are generated by native code. The tool translates |
| instruction addresses into a readable format that contains things such |
| as the function, source file, and line number corresponding to each stack frame. |
| For more information and a usage example, see <code>docs/NDK-STACK.html</code>. |
| </li> |
| </ul> |
| </dd> |
| <dt>Other changes:</dt> |
| <dd><code>arm-eabi-4.4.0</code>, which had been deprecated since NDK r5, has been |
| removed from the NDK distribution.</dd> |

| Android NDK, Revision 5c</a> <em>(June 2011)</em> |
| |
| <div class="toggleme"> |
| <p>This release of the NDK does not include any new features compared to r5b. The r5c release |
| addresses the following problems in the r5b release:</p> |
| <dl> |
| <dt>Important bug fixes:</dt> |
| <dd> |
| <ul> |
| <li><code>ndk-build</code>: Fixed a rare bug that appeared when trying to perform parallel |
| builds of debuggable projects.</li> |
| |
| <li>Fixed a typo that prevented <code>LOCAL_WHOLE_STATIC_LIBRARIES</code> to work |
| correctly with the new toolchain and added documentation for this in |
| <code>docs/ANDROID-MK.html</code>.</li> |
| |
| <li>Fixed a bug where code linked against <code>gnustl_static</code> crashed when run on |
| platform releases older than API level 8 (Android 2.2).</li> |
| |
| <li><code>ndk-gdb</code>: Fixed a bug that caused a segmentation fault when debugging Android 3.0 |
| or newer devices.</li> |
| |
| <li><code><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> |
| </ul> |

| |
| <div class="toggleme"> |
| <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> |
| <li>The following <code>ndk-build</code> issues are fixed: |
| <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 compilation with <code>-std=c99</code>.</li> |

| |
| <div class="toggleme"> |
| <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 in this |
| release, read the <code>CHANGES.HTML</code> document included in the downloaded NDK package. |
| </p> |
| <dl> |
| <dt>General notes:</dt> |
| <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> |

| <p>Includes fixes for several issues in the NDK build and debugging scripts — if |

| <dt>General notes:</dt> |
| |
| <dd> |
| <ul> |
| <li>Provides a simplified build system through the new <code>ndk-build</code> build |
| command.</li> |
| |
| <li>Adds support for easy native debugging of generated machine code on production |
| devices through the new <code>ndk-gdb</code> command.</li> |
| |
| <li>Adds a new Android-specific ABI for ARM-based CPU architectures, |
| <code>armeabi-v7a</code>. The new ABI extends the existing <code>armeabi</code> ABI to |
| include these CPU instruction set extensions: |
| |
| <ul> |
| <li>Thumb-2 instructions</li> |
| |
| <li>VFP hardware FPU instructions (VFPv3-D16)</li> |
| |
| <li>Optional support for ARM Advanced SIMD (NEON) GCC intrinsics and VFPv3-D32. |
| Supported by devices such as Verizon Droid by Motorola, Google Nexus One, and |
| others.</li> |
| </ul> |
| </li> |
| |
| <li>Adds a new <code>cpufeatures</code> static library (with sources) that lets your |
| app detect the host device's CPU features at runtime. Specifically, applications can |
| check for ARMv7-A support, as well as VFPv3-D32 and NEON support, then provide separate |
| code paths as needed.</li> |
| |
| <li>Adds a sample application, <code>hello-neon</code>, that illustrates how to use the |
| <code>cpufeatures</code> library to check CPU features and then provide an optimized |
| code path using NEON instrinsics, if supported by the CPU.</li> |
| |
| <li>Lets you generate machine code for either or both of the instruction sets supported |
| by the NDK. For example, you can build for both ARMv5 and ARMv7-A architectures at the |
| same time and have everything stored to your application's final |
| <code>.apk</code>.</li> |
| |
| <li>To ensure that your applications are available to users only if their devices are |
| capable of running them, Google Play now filters applications based on the |
| instruction set information included in your application — 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="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="{@docRoot}sdk/ndk/overview.html#reqs">System and |
| Software Requirements</a> |
| for the NDK, if you haven't already.</p> |
| |
| <p>To install the NDK, follow these steps:</p> |
| |
| <ol> |
| <li>From the table at the top of this page, select the NDK package that is appropriate for your |
| development computer and download the package.</li> |
| |
| <li>Uncompress the NDK download package using tools available on your computer. 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>.</li> |
| </ol> |
| |
| <p>You are now ready to start working with the NDK.</p> |
| |
| <h2 id="gettingstarted">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> |
| |
| <h2 id="samples">Sample Applications</h2> |
| |
| <p>The NDK includes sample Android applications that illustrate how to use native code in your |
| Android applications. For more information, see <a href= |
| "{@docRoot}sdk/ndk/overview.html#samples">Sample Applications</a>.</p> |
| |
| <h2 id="forum">Discussion Forum and Mailing List</h2> |
| |
| <p>If you have questions about the NDK or would like to read or contribute to discussions about |
| it, please visit the <a href="http://groups.google.com/group/android-ndk">android-ndk</a> group |
| and mailing list.</p> |
