Changelog

Report issues to GitHub.

For Android Studio issues, go to https://b.android.com and file a bug using the
Android Studio component, not the NDK component.

If you're a build system maintainer that needs to use the tools in the NDK
directly, see the build system maintainers guide.

Announcements

  • Android V will allow OEMs to ship arm64-v8a and x86_64 devices with 16KiB page
    sizes. Devices that use this configuration will not be able to run existing
    apps that use native code. To be compatible with these devices, applications
    will need to rebuild all their native code to be 16KiB aligned, and rewrite
    any code which assumes a specific page size. ndk-build and CMake have options
    to enable this mode (see note about APP_SUPPORT_FLEXIBLE_PAGE_SIZES and
    ANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES below). A future version of the NDK will
    enable this mode by default. If you're using or maintaining a third-party
    build system, consult the build system maintainers guide for instructions.

    See Support 16 KB page sizes for more information.

Changes

  • Updated LLVM to clang-r522817. See clang_source_info.md in the toolchain
    directory for version information.
    • Issue 1728: Clang now emits an error for invalid Android target versions.
    • Issue 1853: clang-scan-deps is now included.
    • Issue 1947: Fixed various function multi-versioning crashes.
    • Issue 1963: Fixed undefined behavior in std::unexpected::has_value().
    • Issue 1988: Added aarch64 support for preserve_all calling convention.
    • Issue 2007: Fixed crash in class template argument deduction caused by
      self-referential friend declaration.
  • A RISC-V sysroot (AKA riscv64, or rv64) has been added. It is not
    supported. It is present to aid bringup for OS vendors, but it's not yet a
    supported Android ABI. It will not be built by default.
  • Issue 1856: Target-prefixed cmd wrappers for clang should now behave
    appropriately when the first argument includes quotes. You probably do not
    need to use those wrappers.     In most cases where you would use
    aarch64-linux-android21-clang, you can instead use clang -target aarch64-linux-android21, e.g. CC="clang -target aarch64-linux-android21" ./configure. The wrappers are only needed when working with systems that do
    not properly handle a CC that includes arguments.
  • Issue 1898: ndk-stack now tolerates 0x prefixed addresses.
  • Issue 1921: ANDROID_USE_LEGACY_TOOLCHAIN_FILE value is now preserved
    during try-compile steps when ON.
  • Issue 1974: Unintentionally shipped Vulkan headers have been removed from
    sources/third_party/vulkan. The standard Vulkan headers are included in the
    Android sysroot, which Clang will find automatically.
  • Issue 1993: ndk-stack now tolerates invalid UTF-8 characters in the trace.
  • Issue 1994: Fixed ndk-gdb/ndk-lldb to use the correct path for
    make and other tools.
  • Added APP_SUPPORT_FLEXIBLE_PAGE_SIZES for ndk-build and
    ANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES for CMake. Set to
    APP_SUPPORT_FLEXIBLE_PAGE_SIZES := true in your Application.mk or pass
    -DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON to CMake (via
    android.defaultConfig.externalNativeBuild.cmake.arguments if you're using
    the Android Gradle Plugin) to build your code to be compatible with devices
    that use a 16KiB page size. Third-party build system users and maintainers
    should consult the build system maintainers guide.
  • Symlinks are now properly preserved in the macOS App Bundle. The NDK installed
    via that method is now the same size as the one installed via the SDK manager.
  • The unsupported libclang, libclang-cpp, libLLVM, and libLTO libraries were
    removed to save space.
