Summary:

Google [documents](https://developer.android.com/ndk/guides/middleware-vendors#choosing_api_levels_and_ndk_versions) the expected NDK to NDK compatibility:

> NDK versions are largely compatible with each other, but occasionally there are changes that break compatibility. If you know that all of your users are using the same version of the NDK, it's best to use the same version that they do. Otherwise, use the newest version.
