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
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 r346389c.
- Updated libc++ to r350972.
- Add Android Q Beta 1 APIs:
- MIDI (
- Extensions to several APIs from previous releases.

LOCAL_LDFLAGSnow take precedence over
- This is not intended to be a comprehensive list of all outstanding bugs.
thread_localvariables 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
- Issue 70838247: Gold emits broken debug information for AArch64. AArch64 still uses BFD by default.
Issue 855: LLD may hang on Windows when using multithreaded linking.
ndk-build will automatically disable multithreaded linking in this situation,
but CMake users and custom build systems should pass
-Wl,--no-threadswhen using LLD on Windows. The other linkers and operating systems are unaffected.
Issue 884: Third-party build systems must pass
-fno-addrsigto Clang for compatibility with binutils. ndk-build, CMake, and standalone toolchains handle this automatically.
- Issue 888: lld does not support compressed symbols on Windows. Clang also cannot generate compressed symbols on Windows, but this can be a problem when using artifacts built from Darwin or Linux.
Issue 906: Clang does not pass
-march=armv7-ato the assembler when using
-fno-integrated-as. This results in the assembler generating ARMv5 instructions. Note that by default Clang uses the integrated assembler which does not have this problem. To workaround this issue, explicitly use
-march=armv7-awhen building for 32-bit ARM with the non-integrated assembler, or use the integrated assembler. ndk-build and CMake already contain these workarounds.
Issue 1004: Clang outputs debug info with bad line number info when
compiling for ARM64 and
-O0(no optimizations). Third-party build systems can pass
-fno-experimental-iselto Clang to work around this issue.
- 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.
