I'm not an expert but from their documentation it looks like you could watch the PlayerState
. I'm also not sure when a PlayerState
event would trigger but if it's coming back relatively often you could check the track
value and see if it's gone to null
, or another value and work using that.
Here's a Java example from their website:
// Subscribe to PlayerState
mSpotifyAppRemote.getPlayerApi()
.subscribeToPlayerState()
.setEventCallback(new Subscription.EventCallback<PlayerState>() {
public void onEvent(PlayerState playerState) {
// See what values are in playerState, might be able to determine
// if it's now randomly playing?
final Track track = playerState.track;
if (track != null) {
Log.d("MainActivity", track.name + " by " + track.artist.name);
// If the track is now different, your song has finished, stop it?
}
}
});
I've put a few extra comments in the code above that might yield some results!
