  • GCC is no longer supported. It will be removed in NDK r18.

  • libc++ is now the default STL for CMake and standalone toolchains. If you manually selected a different STL, we strongly encourage you to move to libc++. Note that ndk-build still defaults to no STL. For more details, see this blog post.

  • gnustl and stlport are deprecated and will be removed in NDK r18.

  • Support for ARMv5 (armeabi), MIPS, and MIPS64 has been removed. Attempting to build any of these ABIs will result in an error.

  • The Play Store will require 64-bit support when uploading an APK beginning in August 2019. Start porting now to avoid surprises when the time comes. For more information, see this blog post.


  • Updated Clang to build 4393122 based on ???
  • AArch64 now uses gold by default, matching the other architectures.
  • Updated gtest to upstream revision 0fe96607d85cf3a25ac40da369db62bbee2939a5.
  • Fixed parsing of the NDK revision in CMake. NDK version information is now available in the following CMake variables:
    • ANDROID_NDK_REVISION: The full string in the file.
    • ANDROID_NDK_MAJOR: The major revision of the NDK. For example: the 16 in r16b.
    • ANDROID_NDK_MINOR: The minor revision of the NDK. For example: the b (represented as 1) in r16b.
    • ANDROID_NDK_BUILD: The build number of the NDK. This is 0 in the case of a local development build.
    • ANDROID_NDK_BETA: The beta version of the NDK. This is 0 for a stable release.

Known Issues

  • This is not intended to be a comprehensive list of all outstanding bugs.
  • Issue 360: thread_local variables with non-trivial destructors will cause segfaults if the containing library is dlcloseed on devices running M or newer, or devices before M when using a static STL. The simple workaround is to not call dlclose.
