Android NDK/バージョン
Android NDK/サンプル
Android Studio 2.2
- Android Studio's default build tool for native libraries is CMake.
- Android Studio also supports ndk-build due to the large number of existing projects that use the build toolkit to compile their native code.
Android Studioからインストール
- %LOCALAPPDATA%\Android\sdk\ndk-bundleに入る
中身
Development tools
The NDK includes a set of cross-toolchains (compilers, linkers, etc..) that can generate native ARM binaries on Linux,Mac OS X, and Windows (with Cygwin) platforms.
It provides a set of system headers for stable native APIs that are guaranteed to be supported in all later releases of the platform:
- libc (C library) headers
- libm (math library) headers
- JNI interface headers
- libz? (Zlib compression) headers
- liblog? (Android logging) header
- OpenGL ES 1.1 and OpenGL ES 2.0 (3D graphics libraries) headers
- libjnigraphics (Pixel buffer access) header (for Android 2.2 and above).
- A Minimal set of headers for C++ support
- OpenSL ES native audio libraries
- Android native application APIS

要らなくなった作業
- Previous releases required you to run the 'build/host-setup.sh' script to configure the NDK. However, this step has been removed in release 4 (a.k.a. r4).

Android Studio/NDK
- Android Studio上でのNDKサポートについて現在のところGoogleからのアナウンスはありません。
http://samuraism.com/2013/05/17/882
- As of Jan 2015 the NDK support for Android studio is still unusable. A cryptic message says: "Alternative will be provided in the future."
- Version 0.7+: They suggested to still use ndk-build / ant
- Version 0.8+: They've introduced a minimal NDK support
- Version 1.0.0: It looked like NDK support was going to be official
- Version 1.0.2: It now looks like NDK support is deprecated.
