How to do I check when a YouTube video has finished playing in the official YouTube Android app? In the LogCat I see things such as: VideoStage: MEDIA_PLAYING_VIDEO. Is there any way to detect when this finishes?

You could use MediaPlayer. It has an isPlaying method to check if music/videos are currently playing. Just set a Boolean to true while it's playing and check the isPlaying method against that Boolean to see if it changed from True to False.
Otherwise Youtube (or google) may have some specific API's
EDIT:
I looked into here; and it appears that there is an API for youtube.
you can use the method PlayerStateChangeListener for the YoutubePlayerclass to get the listener and implement the method OnVideoEnded
