I'm currently working on it.
I think a library will not be necessary because only 3 methods needs to be called and this can be done with JavaObject or Reflection.
But I think it is quite complicated to use (much code, events, inline Java code etc.) and maybe I can wrap some of the functionality into a class and make usage simpler.
Maybe I should write a tutorial how to use this.
Problem is that you HAVE to use it if you want to use targetSdkVersion=23 or above.
