Announcements

• LLD is now available for testing. AOSP is in the process of switching to using LLD by default and the NDK will follow (timeline unknown). Test LLD in your app by passing -fuse-ld=lld when linking.

• 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.

Changes

• Updated Clang to r346389c.
• Updated libc++ to r350972.
• Add Android Q Beta 1 APIs:
  • MIDI (<amidi/AMidi.h>).
  • Binder.
  • Extensions to several APIs from previous releases.
• Issue 908: LOCAL_LDFLAGS now take precedence over APP_LDFLAGS.

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.
• Issue 70838247: Gold emits broken debug information for AArch64. AArch64 still uses BFD by default.
• This version of the NDK is incompatible with the Android Gradle plugin version 3.0 or older. If you see an error like No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android, update your project file to use plugin version 3.1 or newer. You will also need to upgrade to Android Studio 3.1 or newer.
