YouTubePlayerSupportFragment fullscreen button forces orientation change and does not enter fullscreen

Question

i am creating YouTubePlayerSupportFragment. Playing in portrait mode works just fine. As soon as i click the fullscreen button of the player it forces an orientation change and recreates the activity i am in (the video stops playing and the fragment is recreated).

this is how i create the fragment:

fragment = (YouTubePlayerSupportFragment) getSupportFragmentManager().findFragmentById(R.id.youtube_fragment);
fragment.initialize(Config.YOUTUBE_API_KEY, this);

The only similar thing on StackOverflow I could find was this question: YouTubePlayerSupportFragment starts duplicate Activity

This guy has the same problem but no answer so far.

Answer 1

my problem was i did't call super.onSaveInstanceState(b) on my own onSaveInstanceState...
