MediaControllerのバグかもしれない

MediaControllerのバグかもしれない

1. VideoViewを使って、横位置FullScreenで動画を再生させる。
2. MediaControllerを使って、pauseを手動で行う。動画は停止状態になる。
3. 端末を縦位置にする。configuration changeを発生させる。
4. Logが真っ赤になる。

真っ赤に流れるボクのLogCat
同じことを２回行うと、端末が反応しなくなり、再起動が必要になる。

解答は次のサイトにあった。
Android MediaPlayer with MediaController: LogCat error “Activity has leaked window that was originally added here”

onSaveInstanceState()やonCreate(Bundle savedInstanceState)による作り込みを完成させてから、こんな現象が発生することを知った。むむむ！
