CHANGELOG.md

Changelog

Report issues to GitHub.

For Android Studio issues, follow the docs on the Android Studio site.

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.

  For migration tips, see Unified Headers Migration Notes.

• 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.

• The CMake toolchain file now supports building assembly code written in YASM to run on x86 and x86-64 architectures. To learn more, see YASM in CMake.

r15c

• Fixes for _FILE_OFFSET_BITS=64 APIs. See android/ndk#459 and android/ndk#442.
• Fix termios.h APIs for old target APIs. See android/ndk#441.
• Added an inline for ffs to maintain compatibility with the deprecated headers. See android/ndk#439.
• Added legacy pthread API declarations for compatibility with old releases. See android/ndk#420 and android/ndk#423.

r15b

• Fix libsync header/library mismatch: https://issuetracker.google.com/62229958.
• Several libc header updates to improve compatibility with code written for other systems.

APIs

• Added native APIs for Android O. 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 4053586. This is built from Clang 5.0 SVN at r300080.
• Clang now supports OpenMP (except on MIPS/MIPS64): android/ndk#9.

libc++

• We've begun slimming down and improving libandroid_support to fix libc++ reliability issues. android/ndk#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: android/ndk#374.
• ndk-gdb doesn't work on the Samsung Galaxy S8. https://android-review.googlesource.com/408522/ fixes this and will be in a future release. There is no workaround (but debugging in Android Studio should work).
• 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 android/ndk#399.
