Announcements

• Unified Headers are now enabled by default.

  Note: The deprecated headers will be removed in a future release, most likely r16. If they do not work for you, file bugs now.

• GCC is no longer supported. It will not be removed from the NDK just yet, but is no longer receiving backports. It cannot be removed until after libc++ has become stable enough to be the default, as some parts of gnustl are still incompatible with Clang. It will likely be removed after that point.

• Gingerbread (android-9) is no longer supported. The minimum API level target in the NDK is now Ice Cream Sandwich (android-14). If your APP_PLATFORM is set lower than android-14, android-14 will be used instead.

• NDK r15's release cycle is going to be extended somewhat due to the O developer preview logistics. r15 beta 1 is specifically for the O APIs rather than the libandroid_support rework we originally intended for this release. As such, the libandroid_support work will be coming in a later beta (hopefully beta 2). We'll be doing at least 3 beta releases this cycle.

APIs

• Added native APIs for Android O Beta 1. To learn more about these APIs, see the Native APIs overview.
  • AAudio API
  • Hardware Buffer API
  • Shared Memory API

NDK

• awk is no longer in the NDK. We've replaced all uses of awk with Python.

Clang

• Clang has been updated to build 3960126. This is built from Clang 5.0 SVN at r300080.
• Clang now supports OpenMP (except on MIPS/MIPS64): https://github.com/android-ndk/ndk/issues/9.

libc++

• We've begun slimming down and improving libandroid_support to fix libc++ reliability issues. https://github.com/android-ndk/ndk/issues/300.

Known Issues

• This is not intended to be a comprehensive list of all outstanding bugs.
• gabi++ (and therefore stlport) binaries can segfault when built for armeabi: https://github.com/android-ndk/ndk/issues/374.
• MIPS64 must use the integrated assembler. Clang defaults to using binutils rather than the integrated assmebler for this target. ndk-build and cmake handle this for you, but make sure to use -fintegrated-as for MIPS64 for custom build systems. See https://github.com/android-ndk/ndk/issues/399.
