It was announced that with the next major release, the ExoPlayer can be played from the app-specific directory even without READ permission. This has at least worked with the player component before, if the permission was previously denied. This works now neither with the ExoPlayer nor with the Player.
Thanks to Mika for adding the Completed event (in Kodular Eagle).

If the permission is denied, neither the ExoPlayer nor the player will play. So permission must be granted for players to play.
This is not required for all other App Inventor distributions (AI2, AppyBuilder, …).
