Clean up demo app source building.

Browse Source 
- Rename preparePlayer to initializePlayer, to reflect the fact that the
preparing state is gone. Replace playerNeedsPrepare with playerNeedsSource.
- playWhenReady is now always true in calls to initializePlayer.
- Handle the intent just before setting the source.
- Use URIs consistently instead of Strings to avoid reparsing.
- onShown becomes initializePlayer.
