Certain NDK APIs are available at higher versions than we currently support, for example one can access the AChoreographer on API 24+ (whereas we support API 16+), and proposed image decoding APIs would enable expanded support for image formats without a JNI hop.

It should be possible to use dlopen/dlsym to dynamically use these methods if they are available.

I suspect that we could improve performance by avoiding a JNI hop on each vsync by accessing the choreographer dynamically from C++ when API >= 24. That would be an interesting case to prove out.
