What is the recommended way to listen for CastPlayer playback state changes? #1475

I am developing a radio app using media3. The app has a MediaLibraryService for playback and a Fragment that controls the UI. The Fragment listens to playback changes using a Player.Listener that has been added to a MediaController. That all works great so far.

I recently began integrating Google Cast into the app. Playback through a CastPlayer in the MediaLibraryService works fine. But now I am stuck: How do I receive information about CastPlayer playback state changes in my Fragment? The existing Player.Listener (basically created in the way recommended here) does not get called at the moment.

I just found the media3 branch of UAMP. My issue was a buggy function that handled swapping between CastPlayer and ExoPlayer. As soon as I adapted ReplaceableForwardingPlayer for my needs, my problem was more or less solved.
