I think you should only keep this interface if there is an obvious other
consumer. Otherwise, it sounds like a lot of indirection.

Ack.

Maybe an int with final values would be better? PAUSE/PLAY.
onPlaybackStateChanged(true) doesn't mean anything unless you go look at that
file.

You suggested that I change from PlaybackState enum-like constants to a boolean
:) Now you don't like it here.
Maybe I should have onResumed/onPaused.
