/**
* Displays a video file. The FastVideoView class
* can load images from various sources (such as resources or content
* providers), takes care of computing its measurement from the video so that
* it can be used in any layout manager, and provides various display options
* such as scaling and tinting.
*
* Note: FastVideoView does not retain its full state when going into the
* background. In particular, it does not restore the current play state,
* play position, selected tracks. Applications should
* save and restore these on their own in
* {@link android.app.Activity#onSaveInstanceState} and
* {@link android.app.Activity#onRestoreInstanceState}.
* Also note that the audio session id (from {@link #getAudioSessionId}) may
* change from its previously returned value when the FastVideoView is restored.
