| /** |
| * Displays a video file. VideoView2 class is a View class which is wrapping {@link MediaPlayer2} |
| * so that developers can easily implement a video rendering application. |
| * |
| * <p> |
| * <em> Data sources that VideoView2 supports : </em> |
| * VideoView2 can play video files and audio-only files as |
| * well. It can load from various sources such as resources or content providers. The supported |
| * media file formats are the same as {@link MediaPlayer2}. |
| * |
| * <p> |
| * <em> View type can be selected : </em> |
| * VideoView2 can render videos on top of TextureView as well as |
| * SurfaceView selectively. The default is SurfaceView and it can be changed using |
| * {@link #setViewType(int)} method. Using SurfaceView is recommended in most cases for saving |
| * battery. TextureView might be preferred for supporting various UIs such as animation and |
| * translucency. |
| * |
| * <p> |
| * <em> Differences between {@link VideoView} class : </em> |
| * VideoView2 covers and inherits the most of |
| * VideoView's functionalities. The main differences are |
| * <ul> |
| * <li> VideoView2 inherits FrameLayout and renders videos using SurfaceView and TextureView |
| * selectively while VideoView inherits SurfaceView class. |
| * <li> VideoView2 is integrated with MediaControlView2 and a default MediaControlView2 instance is |
| * attached to VideoView2 by default. If a developer does not want to use the default |
| * MediaControlView2, needs to set enableControlView attribute to false. For instance, |
| * <pre> |
| * <VideoView2 |
| * android:id="@+id/video_view" |
| * xmlns:widget="http://schemas.android.com/apk/com.android.media.update" |
| * widget:enableControlView="false" /> |
| * </pre> |
| * If a developer wants to attach a customed MediaControlView2, then set enableControlView attribute |
| * to false and assign the customed media control widget using {@link #setMediaControlView2}. |
| * <li> VideoView2 is integrated with MediaPlayer2 while VideoView is integrated with MediaPlayer. |
| * <li> VideoView2 is integrated with MediaSession and so it responses with media key events. |
| * A VideoView2 keeps a MediaSession instance internally and connects it to a corresponding |
| * MediaControlView2 instance. |
| * </p> |
| * </ul> |
| * |
| * <p> |
| * <em> Audio focus and audio attributes : </em> |
| * By default, VideoView2 requests audio focus with |
| * {@link AudioManager#AUDIOFOCUS_GAIN}. Use {@link #setAudioFocusRequest(int)} to change this |
| * behavior. 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 |
| * modify them. |
| * |
| * <p> |
| * Note: VideoView2 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}. |
