![]() ![]() However, before using Android NDK you need to be a great connoisseur of these native-code languages and make sure that your computer meets all the system requirements, otherwise you can not benefit off of all the features that the toolset comes with. We should fix this ASAP, but this actually is not a regression from r10e.Android NDK is a reliable and effective toolset specially designed for Android and Java developers who need to implement parts of their app using programming languages such as C or C#. Yes, this does mean that exception handling will often fail when using c _shared on ARM32. The test config file ( $NDK/sources/cxx-stl/llvm-libc /libcxx/test/libcxx/ndk/test/config.py) can be modified to use -lc _static before -lgcc and the tests will then work on ARM (but will take considerably longer to run). ![]() The ARM32 specific failures are because the libgcc unwinder does not get along with the LLVM unwinder. In general, most of these tests are locale related and fail because we don't support anything beyond the C locale. Note that these tests are far from failure free (especially on 32-bit ARM). To run the libc tests: $ NDK =/ path / to / extracted / ndk sources / cxx - stl / llvm - libc / llvm / ndk - test. ![]() The libc tests are not currently integrated into the main NDK tests. If you do not have a device capable of running the tests, you can run just the build or awk test suites with the -suite flag. The full test suite includes tests which run on a device or emulator, so you'll need to have adb in your path and ANDROID_SERIAL set if more than one device/emulator is connected. To run the tests with Clang, use the option -toolchain clang. From the NDK source directory (not the extracted package): $ NDK =/ path / to / extracted / ndk python tests / run - all. Running the NDK tests requires a complete NDK package (see previous steps). If you need to re-run just the packaging step without going through a build, packaging is handled by build/tools/package.py. This will take a little longer though, so it may not be desired for day to day development. The simplest way to package an NDK on Linux is to just omit the -no-package flag when running checkbuild.py. py - system windowsĬheckbuild.py also accepts a variety of other options to speed up local builds, namely -arch and -module. py - no - packageįor Windows, from Linux: $ python checkbuild. Host/Target prebuilts For Linux or Darwin: $ python checkbuild. com / platform / manifest \Īdditional Linux Dependencies (available from apt): sources/ contains modules useful in samples and apps via $(call import-module, $MODULE)Ĭheck out the branch master-ndk repo init - u https :// android.build/ contains the ndk-build system and scripts to rebuild NDK.sources/cxx-stl/$STL contains the headers and libraries for the various C STLs.The build system sets -sysroot to one of these directories based on user-specified APP_ABI and APP_PLATFORM.platforms/android-N/arch-$ARCH_NAME/ contains headers and libraries for each API level.ndk-depends, ndk-stack and ndk-gdb can also be found here.make, awk, python, yasm, and for Windows: cmp.exe and echo.exe.host-tools/ contains build dependencies and additional tools.binutils/ contains the standalone binutils installation for use with Clang.$TOOLCHAIN/setup.mk contains toolchain-specific default CFLAGS/LDFLAGS when this toolchain is used.$TOOLCHAIN/config.mk contains ARCH and ABIS this toolchain can handle.toolchains/ contains GCC and Clang toolchains.The NDK consists of three parts: host binaries, target prebuilts, and others (build system, docs, samples, tests). Target headers and binaries are built on Linux. Systems without a working MinGW compiler can use build/tools/build-mingw64-toolchain.sh to generate their own and be added to the PATH for build scripts to discover.īuilding binaries for Mac OS X requires at least 10.8. Windows host binaries are built via MinGW cross compiler. Note: This document is for developers of the NDK, not developers that use the NDK.īoth Linux and Windows host binaries are built on Linux machines. The NDK allows Android application developers to include native code in their Android application packages, compiled as JNI shared libraries.ĭiscussions related to the Android NDK happen on the android-ndk Google Group. ![]()
