Skia does not have a stable ABI, which is a requirement for inclusion in the NDK: https://github.com/google/skia/blob/master/experimental/c-ap...

It has a stable API for Java clients on Android, if Google actually would care they could expose that one.

And in any case, creating a 2D abstraction layer stable API on top of platforms specific version APIs, specially given that all NDK APIs are C based even if written in C++, it is not rocket science, rather a matter of wanting to do it.
