Since GDB is still at version GDB-7.3.x in 980GCC 4.6 (the default for ARM and MIPS), you must set 981<code>NDK_TOOLCHAIN_VERSION=4.8</code> or <code>4.9</code> to enable ndk-gdb to select GDB 7.6.</li> 982 <li>Added the <code>-mssse3</code> build option to provide SSSE3 support, and made it the default for ABI x86 983(upgrading from SSE3). The image released by Google does not contain SSSE3 instructions.</li> 984 <li>Updated GCC 4.8 to 4.8.3.</li> 985 <li>Improved ARM libc++ EH support by switching from gabi++ to libc++abi.

The problem was that Clang added <code>-pie</code> for Android 1069targets if neither <code>-shared</code> nor <code>-static</code> existed. This behavior, which was 1070incorrect, caused the linker to complain that <code>-shared</code> and <code>-pie</code> could not 1071co-exist.</li> 1072 1073 </ul> 1074 </dd> 1075 1076 1077 <dt>Other changes:</dt> 1078 <dd> 1079 <ul> 1080 <li>Added <code>arm_neon.h</code> to the x86 toolchain so that it now emulates ~47% of 1081Neon.

The 1112<code>NDK_TOOLCHAIN_VERSION=clang</code> option now picks Clang 3.4. GCC 4.6 is 1113still the default compiler.</li> 1114 <li>Added <code>APP_ABI=armeabi-v7a-hard</code>, with 1115additional multilib option <code>-mfloat-abi=hard</code>. These options are for 1116use with ARM GCC 4.6/4.8 and Clang 3.3/3.4 (which use 4.8's assembler, linker, 1117and libs). When using these options, note the following changes:</li> 1118 <ul> 1119 <li> When executing the <code>ndk-build</code> script, add the 1120following options for armeabi-v7a target: 1121<pre>TARGET_CFLAGS += -mhard-float -D_NDK_MATH_NO_SOFTFP=1 1122TARGET_LDFLAGS += -Wl,--no-warn-mismatch -lm_hard</pre> 1123The built library is copied to <code>libs/armeabi-v7a</code>. For make to 1124behave as expected, you cannot specify both <code>armeabi-v7a</code> and 1125<code>armeabi-v7a-hard</code> as make targets (i.e., on the APP_ABI= line). 1126Doing so causes one of them to be ignored. Note that <code>APP_ABI=all</code> 1127is still equivalent to 1128<code>armeabi armeabi-v7a x86 mips</code>.</li> 1129 <li>The <code>make-standalone-toolchain.sh</code> script copies 1130additional libaries under <code>/hard</code> directories. 1131 Add the above <code>CFLAGS</code> and <code>LFLAGS</code> to your 1132makefile to enable GCC or Clang to link with 1133 libraries in <code>/hard</code>.</li> 1134 </ul> 1135 <li>Added the yasm assembler, as well as <code>LOCAL_ASMFLAGS</code> 1136and <code>EXPORT_ASMFLAGS</code> flags for x86 1137targets. The <code>ndk-build</code> script uses 1138<code>prebuilts/*/bin/yasm*</code> to build <code>LOCAL_SRC_FILES</code> that 1139have the <code>.asm</code> extension.</li> 1140 <li>Updated MClinker to 2.6.0, which adds <code>-gc-sections</code> 1141support.</li> 1142 <li>Added experimental libc++ support (upstream r201101).

(<a href="http://b.android.com/57267">Issue 57267</a>)</li> 1756 </ul> 1757 </li> 1758 <li>Added more formatting in NDK {@code docs/} and miscellaneous documentation fixes. 1759 </li> 1760 <li>Added support for a thin archive technique when building static libraries. 1761 (<a href="http://b.android.com/40303">Issue 40303</a>)</li> 1762 <li>Updated script {@code make-standalone-toolchain.sh} to support the {@code stlport} 1763 library in addition to {@code gnustl}, when you specify the option 1764 {@code --stl=stlport}. For more information, see {@code STANDALONE-TOOLCHAIN.html}.</li> 1765 <li>Updated the {@code make-standalone-toolchain.sh} script so that the 1766 {@code --llvm-version=} option creates the {@code $TOOLCHAIN_PREFIX-clang} and 1767 {@code $TOOLCHAIN_PREFIX-clang++} scripts in addition to {@code clang} and 1768 {@code clang++}, to avoid using the host's clang and clang++ definitions by accident. 1769 </li> 1770 <li>Added two flags to re-enable two optimizations in upstream Clang but disabled in 1771 NDK for better compatibility with code compiled by GCC: 1772 <ul> 1773 <li>Added a {@code -fcxx-missing-return-semantics} flag to re-enable <em>missing 1774return 1775 semantics</em> in Clang 3.2+. Normally, all paths should terminate with a return 1776 statement for a value-returning function. If this is not the case, clang inserts 1777 an undefined instruction (or trap in debug mode) at the path without a return 1778 statement. If you are sure your code is correct, use this flag to allow the 1779 optimizer to take advantage of the undefined behavior. If you are not sure, do not 1780 use this flag. The caller may still receive a random incorrect value, but the 1781 optimizer will not exploit it and make your code harder to debug.</li> 1782 <li>Added a {@code -fglobal-ctor-const-promotion} flag to re-enable 1783 promoting global variables with static constructor to be constants. With this flag, 1784 the global variable optimization pass of LLVM tries to evaluate the global 1785 variables with static constructors and promote them to global constants. Although 1786 this optimization is correct, it may cause some incompatability with code compiled 1787 by GCC. For example, code may do {@code const_cast} to cast the constant to mutable 1788 and modify it. In GCC, the variable is in read-write and the code is run by 1789 accident. In Clang, the const variable is in read-only memory and may cause your 1790 application to crash.</li> 1791 </ul> 1792 </li> 1793 <li>Added {@code -mldc1-sdc1} to the MIPS GCC and Clang compilers. By default, compilers 1794 align 8-byte objects properly and emit the {@code ldc1} and {@code sdc1} instructions 1795 to move them around. If your app uses a custom allocator that does not always align 1796 with a new object's 8-byte boundary in the same way as the default allocator, your app 1797 may crash due to {@code ldc1} and {@code sdc1} operations on unaligned memory. In this 1798 case, use the {@code -mno-ldc1-sdc1} flag to workaround the problem.</li> 1799 <li>Downgraded the event severity from warning to info if {@code APP_PLATFORM_LEVEL} is 1800 larger than {@code APP_MIN_PLATFORM_LEVEL}. The {@code APP_PLATFORM_LEVEL} may be lower 1801 than {@code APP_PLATFORM} in {@code jni/Application.mk} because the NDK does not have 1802 headers for all levels. In this case, the actual level is shifted downwards. The 1803 {@code APP_MIN_PLATFORM_LEVEL} is specified by the {@code android:minSdkVersion} in 1804 your application's manifest. 1805 (<a href="http://b.android.com/39752">Issue 39752</a>)</li> 1806 <li>Added the {@code android_getCpuIdArm()} and {@code android_setCpuArm()} methods to 1807 {@code cpu-features.c}. This addition enables easier retrieval of the ARM CPUID 1808 information. (<a href="http://b.android.com/53689">Issue 53689</a>)</li> 1809 <li>Modified {@code ndk-build} to use GCC 4.7's {@code as/ld} for Clang compiling. 1810 <p class="note"><strong>Note:</strong> 1811 In GCC 4.7, {@code monotonic_clock} and {@code is_monotonic} have been renamed to 1812 {@code steady_clock} and {@code is_steady}, respectively.</p></li> 1813 <li>Added the following new warnings to the {@code ndk-build} script: 1814 <ul> 1815 <li>Added warnings if {@code LOCAL_LDLIBS/LDFLAGS} are used in static library 1816 modules.</li> 1817 <li>Added a warning if a configuration has no module to build.</li> 1818 <li>Added a warning for non-system libraries being used in 1819 {@code LOCAL_LDLIBS/LDFLAGS} of a shared library or executable modules.</li> 1820 </ul> 1821 </li> 1822 <li>Updated build scripts, so that if {@code APP_MODULES} is not defined and only static 1823 libraries are listed in {@code Android.mk}, the script force-builds all of them. 1824 (<a href="http://b.android.com/53502">Issue 53502</a>)</li> 1825 <li>Updated {@code ndk-build} to support absolute paths in {@code LOCAL_SRC_FILES}.</li> 1826 <li>Removed the {@code *-gdbtui} executables, which are duplicates of the {@code *-gdb} 1827 executables with the {@code -tui} option enabled.</li> 1828 <li>Updated the build scripts to warn you when the Edison Design Group (EDG) compiler 1829 front-end turns {@code _STLP_HAS_INCLUDE_NEXT} back on. 1830 (<a href="http://b.android.com/53646">Issue 53646</a>)</li> 1831 <li>Added the environment variable {@code NDK_LIBS_OUT} to allow overriding of the 1832 path for {@code libraries/gdbserver} from the default {@code $PROJECT/libs}. 1833 For more information, see {@code OVERVIEW.html}.</li> 1834 <li>Changed ndk-build script defaults to compile code with format string protection 1835 {@code -Wformat -Werror=format-security}.

The new <code><OMXAL/OpenMAXAL.h></code> and 3003 <code><OMXAL/OpenMAXAL_Android.h></code> headers allow applications targeting 3004 API level 14 to perform multimedia output directly from native code by using a new 3005 Android-specific buffer queue interface. For more details, see 3006 <code>docs/openmaxal/index.html</code> and <a href= 3007 "http://www.khronos.org/openmax/">http://www.khronos.org/openmax/</a>.</li> 3008 3009 <li>Updated the native audio API based on the Khronos Group OpenSL ES 1.0.1? 3010 standard. With API Level 14, you can now decode compressed audio (e.g. MP3, AAC, 3011 Vorbis) to PCM. For more details, see <code>docs/opensles/index.html</code> and 3012 <a href= 3013 "http://www.khronos.org/opensles">http://www.khronos.org/opensles/</a>.</li> 3014 </ul> 3015 </li> 3016 3017 <li>Added CCache support. To speed up large rebuilds, define the 3018 <code>NDK_CCACHE</code> environment variable to <code>ccache</code> (or the path to 3019 your <code>ccache</code> binary). When declared, the NDK build system automatically 3020 uses CCache when compiling any source file. For example: 3021 <pre> 3022export NDK_CCACHE=ccache 3023</pre> 3024 <p class="note"><strong>Note:</strong> CCache is not included in the NDK release 3025 so you must have it installed prior to using it. For more information about CCache, see 3026 <a href="http://ccache.samba.org">http://ccache.samba.org</a>.</p> 3027 </li> 3028 3029 <li>Added support for setting <code>APP_ABI</code> to <code>all</code> to indicate that 3030 you want to build your NDK modules for all the ABIs supported by your given NDK 3031 release. This means that either one of the following two lines in your 3032 <code>Application.mk</code> are equivalent with this release: 3033 <pre> 3034APP_ABI := all 3035APP_ABI := armeabi armeabi-v7a x86 3036</pre> 3037 3038 <p>This also works if you define <code>APP_ABI</code> when calling 3039 <code>ndk-build</code> from the command-line, which is a quick way to check that your 3040 project builds for all supported ABIs without changing the project's 3041 <code>Application.mk file</code>. For example:</p> 3042 <pre> 3043ndk-build APP_ABI=all 3044</pre> 3045 </li> 3046 3047 <li>Added a <code>LOCAL_CPP_FEATURES</code> variable in <code>Android.mk</code> that 3048 allows you to declare which C++ features (RTTI or Exceptions) your module uses. This 3049 ensures that the final linking works correctly if you have prebuilt modules that depend 3050 on these features. See <code>docs/ANDROID-MK.html</code> and 3051 <code>docs/CPLUSPLUS-SUPPORT.html</code> for more details.</li> 3052 3053 <li>Shortened paths to source and object files that are used in build commands. When 3054 invoking <code>$NDK/ndk-build</code> from your project path, the paths to the source, 3055 object, and binary files that are passed to the build commands are significantly 3056 shorter now, because they are passed relative to the current directory. This is useful 3057 when building projects with a lot of source files, to avoid limits on the maximum 3058 command line length supported by your host operating system. The behavior is unchanged 3059 if you invoke <code>ndk-build</code> from a sub-directory of your project tree, or if 3060 you define <code>NDK_PROJECT_PATH</code> to point to a specific directory.</li> 3061 </ul> 3062 </dd> 3063 3064 <dt>Experimental features</dt> 3065 3066 <dd> 3067 You can now build your NDK source files on Windows <em>without</em> Cygwin by calling the 3068 <code>ndk-build.cmd</code> script from the command line from your project path. The 3069 script takes exactly the same arguments as the original <code>ndk-build</code> script. 3070 The Windows NDK package comes with its own prebuilt binaries for GNU Make, Awk and other 3071 tools required by the build. You should not need to install anything else to get a 3072 working build system. 3073 3074 <p class="caution"><strong>Important:</strong> <code>ndk-gdb</code> does not work on 3075 Windows, so you still need Cygwin to debug.</p> 3076 3077 <p>This feature is still experimental, so feel free to try it and report issues on the 3078 <a href="http://b.android.com">public bug database</a> or <a href= 3079 "http://groups.google.com/group/android-ndk">public forum</a>. All samples and unit tests 3080 shipped with the NDK succesfully compile with this feature.</p> 3081 </dd> 3082 3083 <dt>Important bug fixes</dt> 3084 3085 <dd> 3086 <ul> 3087 <li>Imported shared libraries are now installed by default to the target installation 3088 location (<code>libs/<abi></code>) if <code>APP_MODULES</code> is not defined in 3089 your <code>Application.mk</code>. For example, if a top-level module <code>foo</code> 3090 imports a module <code>bar</code>, then both <code>libfoo.so</code> and 3091 <code>libbar.so</code> are copied to the install location. Previously, only 3092 <code>libfoo.so</code> was copied, unless you listed <code>bar</code> in your 3093 <code>APP_MODULES</code> too. If you define <code>APP_MODULES</code> explicitly, the 3094 behavior is unchanged.</li> 3095 3096 <li><code>ndk-gdb</code> now works correctly for activities with multiple categories in 3097 their MAIN intent filters.</li> 3098 3099 <li>Static library imports are now properly transitive. For example, if a top-level 3100 module <code>foo</code> imports static library <code>bar</code> that imports static 3101 library <code>zoo</code>, the <code>libfoo.so</code> will now be linked against both 3102 <code>libbar.a</code> and <code>libzoo.a</code>.</li> 3103 </ul> 3104 </dd> 3105 3106 <dt>Other changes</dt> 3107 3108 <dd> 3109 <ul> 3110 <li><code>docs/NATIVE-ACTIVITY.HTML</code>: Fixed typo. The minimum API level should be 3111 9, not 8 for native activities.</li> 3112 3113 <li><code>docs/STABLE-APIS.html</code>: Added missing documentation listing EGL as a 3114 supported stable API, starting from API level 9.</li> 3115 3116 <li><code>download-toolchain-sources.sh</code>: Updated to download the toolchain 3117 sources from <a href="http://android.googlesource.com">android.googlesource.com</a>, 3118 which is the new location for the AOSP servers.</li> 3119 3120 <li>Added a new C++ support runtime named <code>gabi++</code>. More details about it 3121 are available in the updated <code>docs/CPLUSPLUS-SUPPORT.html</code>.</li> 3122 3123 <li>Added a new C++ support runtime named <code>gnustl_shared</code> that corresponds 3124 to the shared library version of GNU libstdc++ v3 (GPLv3 license). See more info at 3125 <code>docs/CPLUSPLUS-SUPPORT.html</code></li> 3126 3127 <li>Added support for RTTI in the STLport C++ runtimes (no support for 3128 exceptions).</li> 3129 3130 <li>Added support for multiple file extensions in <code>LOCAL_CPP_EXTENSION</code>. For 3131 example, to compile both <code>foo.cpp</code> and <code>bar.cxx</code> as C++ sources, 3132 declare the following: 3133 <pre> 3134LOCAL_CPP_EXTENSION := .cpp .cxx 3135</pre> 3136 </li> 3137 3138 <li>Removed many unwanted exported symbols from the link-time shared system libraries 3139 provided by the NDK. This ensures that code generated with the standalone toolchain 3140 doesn't risk to accidentally depend on a non-stable ABI symbol (e.g. any libgcc.a 3141 symbol that changes each time the toolchain used to build the platform is changed)</li> 3142 3143 <li>Refreshed the EGL and OpenGLES Khronos headers to support more extensions. Note 3144 that this does <em>not</em> change the NDK ABIs for the corresponding libraries, 3145 because each extension must be probed at runtime by the client application. 3146 3147 <p>The extensions that are available depend on your actual device and GPU drivers, 3148 not the platform version the device runs on. The header changes simply add new 3149 constants and types to make it easier to use the extensions when they have been 3150 probed with <code>eglGetProcAddress()</code> or <code>glGetProcAddress()</code>.

Major features for x86 3337 include x86-specific toolchains, system headers, libraries and 3338 debugging support. For all of the details regarding x86 support, 3339 see <code>docs/CPU-X86.html</code> in the NDK package. 3340 3341 <p>By default, code is generated for ARM-based devices, but you can add x86 to your 3342 <code>APP_ABI</code> definition in your <code>Application.mk</code> file to build 3343 for x86 platforms. For example, the following line instructs <code>ndk-build</code> 3344 to build your code for three distinct ABIs:</p> 3345 3346 <pre>APP_ABI := armeabi armeabi-v7a x86</pre> 3347 3348 <p>Unless you rely on ARM-based assembly sources, you shouldn't need to touch 3349 your <code>Android.mk</code> files to build x86 machine code.</p> 3350 3351 </li> 3352 3353 <li>You can build a standalone x86 toolchain using the 3354<code>--toolchain=x86-4.4.3</code> 3355 option when calling <code>make-standalone-toolchain.sh</code>. See 3356 <code>docs/STANDALONE-TOOLCHAIN.html</code> for more details. 3357 </li> 3358 <li>The new <code>ndk-stack</code> tool lets you translate stack traces in 3359 <code>logcat</code> that are generated by native code. The tool translates 3360 instruction addresses into a readable format that contains things such 3361 as the function, source file, and line number corresponding to each stack frame. 3362 For more information and a usage example, see <code>docs/NDK-STACK.html</code>. 3363 </li> 3364 </ul> 3365 </dd> 3366 <dt>Other changes:</dt> 3367 <dd><code>arm-eabi-4.4.0</code>, which had been deprecated since NDK r5, has been 3368 removed from the NDK distribution.</dd> 3369 3370 </dl> 3371 </div> 3372 </div> 3373 3374<div class="toggle-content closed"> 3375 <p><a href="#" onclick="return toggleContent(this)"> 3376 <img src="{@docRoot}assets/images/styles/disclosure_down.png" class="toggle-content-img" 3377 alt="">Android NDK, Revision 5c</a> <em>(June 2011)</em> 3378 </p> 3379 3380 <div class="toggle-content-toggleme"> 3381 <p>This release of the NDK does not include any new features compared to r5b.

The r5b release 3468addresses the 3469 following problems in the r5 release: 3470 </p> 3471 <ul> 3472 <li>The r5 binaries required glibc 2.11, but the r5b binaries are generated with a special 3473 toolchain that targets glibc 2.7 or higher instead. The Linux toolchain binaries now run on 3474Ubuntu 8.04 or higher. </li> 3475 <li>Fixes a compiler bug in the arm-linux-androideabi-4.4.3 toolchain. 3476 The previous binary generated invalid thumb instruction sequences when 3477 dealing with signed chars.</li> 3478 <li>Adds missing documentation for the 3479 "gnustl_static" value for APP_STL, that allows you to link against 3480 a static library version of GNU libstdc++. </li> the 3481 <li>Fixed the following <code>ndk-build</code> issues: 3482 <ul> 3483 <li>A bug that created inconsistent dependency files when a 3484 compilation error occured on Windows. This prevented a proper build after 3485 the error was fixed in the source code.</li> 3486 <li>A Cygwin-specific bug where using very short paths for 3487 the Android NDK installation or the project path led to the 3488 generation of invalid dependency files. This made incremental builds 3489 impossible.</li> 3490 <li>A typo that prevented the cpufeatures library from working correctly 3491 with the new NDK toolchain.</li> 3492 <li>Builds in Cygwin are faster by avoiding calls to <code>cygpath -m</code> 3493 from GNU Make for every source or object file, which caused problems 3494 with very large source trees. In case this doesn't work properly, define 3495<code>NDK_USE_CYGPATH=1</code> in your 3496 environment to use <code>cygpath -m</code> again.</li> 3497 <li>The Cygwin installation now notifies the user of invalid installation paths that 3498contain spaces. Previously, an invalid path 3499 would output an error that complained about an incorrect version of GNU Make, even if the 3500right one was installed. 3501 </ul> 3502 </li> 3503 <li>Fixed a typo that prevented the <code>NDK_MODULE_PATH</code> environment variable from 3504working properly when 3505 it contained multiple directories separated with a colon. </li> 3506 <li>The <code>prebuilt-common.sh</code> script contains fixes to check the compiler for 64-bit 3507 generated machine code, instead of relying on the host tag, which 3508 allows the 32-bit toolchain to rebuild properly on Snow Leopard. The toolchain rebuild scripts 3509now also support 3510 using a 32-bit host toolchain.</li> 3511 <li>A missing declaration for <code>INET_ADDRSTRLEN</code> was added to 3512<code><netinet/in.h></code>.</li> 3513 <li>Missing declarations for <code>IN6_IS_ADDR_MC_NODELOCAL</code> and 3514<code>IN6_IS_ADDR_MC_GLOBAL</code> were added to <code><netinet/in6.h></code>.</li> 3515 <li>'asm' was replaced with '__asm__' in <code><asm/byteorder.h></code> to allow 3516compilation with <code>-std=c99</code>.</li> 3517 </ul> 3518 </div> 3519 </div> 3520 3521<div class="toggle-content closed"> 3522 <p><a href="#" onclick="return toggleContent(this)"> 3523 <img src="{@docRoot}assets/images/styles/disclosure_down.png" class="toggle-content-img" 3524 alt="">Android NDK, Revision 5</a> <em>(December 2010)</em> 3525 </p> 3526 3527 <div class="toggle-content-toggleme"> 3528 <p>This release of the NDK includes many new APIs, most of which are introduced to 3529 support the development of games and similar applications that make extensive use 3530 of native code. Using the APIs, developers have direct native access to events, audio, 3531 graphics and window management, assets, and storage. Developers can also implement the 3532 Android application lifecycle in native code with help from the new 3533 {@link android.app.NativeActivity} class.

See 3569 docs/STANDALONE-TOOLCHAIN.html for the details. The binaries for GCC 4.4.0 are still 3570provided, 3571 but the 4.2.1 binaries were removed.</li> 3572 3573 <li>Adds support for prebuilt static and shared libraries (docs/PREBUILTS.html) and 3574module 3575 exports and imports to make sharing and reuse of third-party modules much easier 3576 (docs/IMPORT-MODULE.html explains why).</li> 3577 3578 <li>Provides a default C++ STL implementation (based on STLport) as a helper module. It 3579can be used either 3580 as a static or shared library (details and usage examples are in 3581sources/android/stlport/README). Prebuilt 3582 binaries for STLport (static or shared) and GNU libstdc++ (static only) are also 3583provided if you choose to 3584 compile against those libraries instead of the default C++ STL implementation. 3585 C++ Exceptions and RTTI are not supported in the default STL implementation. For more 3586information, see 3587 docs/CPLUSPLUS-SUPPORT.HTML.</li> 3588 3589 <li>Includes improvements to the <code>cpufeatures</code> helper library that improves 3590reporting 3591 of the CPU type (some devices previously reported ARMv7 CPU when the device really was 3592an ARMv6). We 3593 recommend developers that use this library to rebuild their applications then 3594 upload to Google Play to benefit from the improvements.</li> 3595 3596 <li>Adds an EGL library that lets you create and manage OpenGL ES textures and 3597 services.</li> 3598 3599 <li>Adds new sample applications, <code>native-plasma</code> and 3600<code>native-activity</code>, 3601 to demonstrate how to write a native activity.</li> 3602 3603 <li>Includes many bugfixes and other small improvements; see docs/CHANGES.html for a 3604more 3605 detailed list of changes.</li> 3606 </ul> 3607 </dd> 3608 </dl> 3609 </div> 3610 </div> 3611 3612<div class="toggle-content closed"> 3613 <p><a href="#" onclick="return toggleContent(this)"> 3614 <img src="{@docRoot}assets/images/styles/disclosure_down.png" class="toggle-content-img" 3615 alt="">Android NDK, Revision 4b</a> <em>(June 2010)</em> 3616 </p> 3617 3618 <div class="toggle-content-toggleme"> 3619 <dl> 3620 <dt>NDK r4b notes:</dt> 3621 3622 <dd> 3623 <p>Includes fixes for several issues in the NDK build and debugging scripts — if 3624 you are using NDK r4, we recommend downloading the NDK r4b build.

Specifically, applications can 3658 check for ARMv7-A support, as well as VFPv3-D32 and NEON support, then provide separate 3659 code paths as needed.</li> 3660 3661 <li>Adds a sample application, <code>hello-neon</code>, that illustrates how to use the 3662 <code>cpufeatures</code> library to check CPU features and then provide an optimized 3663 code path using NEON instrinsics, if supported by the CPU.</li> 3664 3665 <li>Lets you generate machine code for either or both of the instruction sets supported 3666 by the NDK. For example, you can build for both ARMv5 and ARMv7-A architectures at the 3667 same time and have everything stored to your application's final 3668 <code>.apk</code>.</li> 3669 3670 <li>To ensure that your applications are available to users only if their devices are 3671 capable of running them, Google Play now filters applications based on the 3672 instruction set information included in your application — no action is needed on 3673 your part to enable the filtering. Additionally, the Android system itself also checks 3674 your application at install time and allows the installation to continue only if the 3675 application provides a library that is compiled for the device's CPU architecture.</li> 3676 3677 <li>Adds support for Android 2.2, including a new stable API for accessing the pixel 3678 buffers of {@link android.graphics.Bitmap} objects from native code.</li> 3679 </ul> 3680 </dd> 3681 </dl> 3682 </div> 3683 </div> 3684 3685<div class="toggle-content closed"> 3686 <p><a href="#" onclick="return toggleContent(this)"> 3687 <img src="{@docRoot}assets/images/styles/disclosure_down.png" class="toggle-content-img" 3688 alt="">Android NDK, Revision 3</a> <em>(March 2010)</em> 3689 </p> 3690 3691 <div class="toggle-content-toggleme"> 3692 <dl> 3693 <dt>General notes:</dt> 3694 3695 <dd> 3696 <ul> 3697 <li>Adds OpenGL ES 2.0 native library support.</li> 3698 3699 <li>Adds a sample application,<code>hello-gl2</code>, that illustrates the use of 3700 OpenGL ES 2.0 vertex and fragment shaders.</li> 3701 3702 <li>The toolchain binaries have been refreshed for this release with GCC 4.4.0, which 3703 should generate slightly more compact and efficient machine code than the previous one 3704 (4.2.1).
