The brief explanation is that the Handle provides an Android Callable Wrapper to Android. All native Android interfaces extend IJavaObject so they will expect that to be implemented. So the simple answer is that you do not implement Handle or Dispose yourself, however you inherit from Java.Lang.Object which does that for you. So your code will end up looking like this:


Given that IStuff extends IJavaObject. More on this topic can be read in the Xamarin documentation on Android Callable Wrappers
