NDK r23 RC 1 is now available in the beta channel of the SDK manager (use
ndkVersion "23.0.7530507-beta6" in your build.gradle) and for download from
our website. For technical reasons, RC 1 is also known as Beta 6.
The release includes APIs for S Beta 3. See the
changelog for details.
As r23 is the new LTS, when r23 is made stable the support windows for r21 and r22 will end.
