/**

* Displays a video file. The VideoView 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.<p>
|
|
*
|
|
* <em>Note: VideoView does not retain its full state when going into the
|
|
* background.</em> In particular, it does not restore the current play state,
|
|
* play position, selected tracks, or any subtitle tracks added via
|
|
* {@link #addSubtitleSource addSubtitleSource()}. Applications should
|
|
* save and restore these on their own in
|
|
* {@link android.app.Activity#onSaveInstanceState} and
|
|
* {@link android.app.Activity#onRestoreInstanceState}.<p>
|
|
* Also note that the audio session id (from {@link #getAudioSessionId}) may
|
|
* change from its previously returned value when the VideoView is restored.
|
|
* <p>
|
|
* By default, VideoView requests audio focus with {@link AudioManager#AUDIOFOCUS_GAIN}. Use
|
|
* {@link #setAudioFocusRequest(int)} to change this behavior.
|
|
* <p>
|
|
* The default {@link AudioAttributes} used during playback have a usage of
|
|
* {@link AudioAttributes#USAGE_MEDIA} and a content type of
|
|
* {@link AudioAttributes#CONTENT_TYPE_MOVIE}, use {@link #setAudioAttributes(AudioAttributes)} to
|
|
