The Android Native Development Kit (NDK) provides a cross-compiling tool for compiling code written in C/C++ can be compiled to ARM, or x86 native code (or their 64-bit variants) for Android.cite-ref-4[4]cite-ref-5[5] The NDK uses the Clang compiler to compile C/C++. GCC was included until NDK r17, but removed in r18 in 2018.

• Overview

• References

Native libraries can be called from Java code running under the Android Runtime using System.loadLibrary, part of the standard Android Java classes.cite-ref-6[6]cite-ref-7[7]

Command-line tools can be compiled with the NDK and installed using adb.cite-ref-8[8]

Android uses Bionic as its C library, and the LLVM libc++ as its C++ Standard Library. The NDK also includes a variety of other APIs:cite-ref-9[9] zlib compression, OpenGL ES or Vulkan graphics, OpenSL ES audio, and various Android-specific APIs for things like logging, access to cameras, or accelerating neural networks.

The NDK includes support for CMake and its own ndk-build (based on GNU Make). Android Studio supports running either of these from Gradle. Other third-party tools allow integrating the NDK into Eclipsecite-ref-10[10] and Visual Studio.cite-ref-11[11]

For CPU profiling, the NDK also includes simpleperfcite-ref-12[12] which is similar to the Linux perf tool, but with better support for Android and specifically for mixed Java/C++ stacks.
