GCC is no longer supported. It will be removed in NDK r18.
libc++ is now the default STL for CMake and standalone toolchains. If you manually selected a different STL, we strongly encourage you to move to
libc++. Note that ndk-build still defaults to no STL. For more details, see this blog post.
gnustl and stlport are deprecated and will be removed in NDK r18.
Support for ARMv5 (armeabi), MIPS, and MIPS64 has been removed. Attempting to build any of these ABIs will result in an error.
Support for ICS (android-14 and android-15) will be removed from r18.
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.
pthread_cond_timedwait_monotonic_nmpto make it available on ICS.
libandroid_supportis no longer used when your NDK API level is greater than or equal to 21 (Lollipop). Build system maintainers: be sure to update your build systems to account for this.

-fno-integrated-asfor arm32 by default. If your project contains hand written assembly, you may need to pass this flag.
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
