  - setWakeMode
```
public void setWakeMode(android.content.Context context,
                        int mode)
```
    Set the low-level power management behavior for this MediaPlayer. This can be used when the MediaPlayer is not playing through a SurfaceHolder set with setDisplay(SurfaceHolder) and thus can use the high-level setScreenOnWhilePlaying(boolean) feature. This function has the MediaPlayer access the low-level power manager service to control the device's power usage while playing is occurring. The parameter is a combination of PowerManager wake flags. Use of this method requires Manifest.permission.WAKE_LOCK permission. By default, no attempt is made to keep the device awake during playback.
    
    参数:
    
    context - the Context to use
    
    mode - the power/wake mode to set
    
    另请参阅:
    
    PowerManager
  - setScreenOnWhilePlaying
```
public void setScreenOnWhilePlaying(boolean screenOn)
```
    Control whether we should use the attached SurfaceHolder to keep the screen on while video playback is occurring. This is the preferred method over setWakeMode(android.content.Context, int) where possible, since it doesn't require that the application have permission for low-level wake lock access.
    
    参数:
    
    screenOn - Supply true to keep the screen on, false to allow it to turn off.
  - getVideoWidth
```
public int getVideoWidth()
```
    Returns the width of the video.
    
    返回:
    
    the width of the video, or 0 if there is no video, or the width has not been determined yet. The OnVideoSizeChangedListener can be registered via setOnVideoSizeChangedListener(OnVideoSizeChangedListener) to provide a notification when the width is available.
  - native_get_video_width
```
public int native_get_video_width()
```
  - getVideoHeight
```
public int getVideoHeight()
```
    Returns the height of the video.
    
    返回:
    
    the height of the video, or 0 if there is no video, or the height has not been determined yet. The OnVideoSizeChangedListener can be registered via setOnVideoSizeChangedListener(OnVideoSizeChangedListener) to provide a notification when the height is available.
  - native_get_video_height
```
public int native_get_video_height()
```
  - isPlaying
```
public boolean isPlaying()

  - addTimedTextSource
```
public void addTimedTextSource(String path)
```

  - selectTrack
```
public void selectTrack(int index)
```
    Selects a track.
    In any valid state, if it is called multiple times on the same type of track (ie. Video, Audio, Timed Text), the most recent one will be chosen.
    
    The first audio and video tracks are selected by default if available, even though this method is not called. However, no timed text track will be selected until this function is called.
    
    参数:
    
    index - the index of the track to be selected. The valid range of the index is 0..total number of track - 1. The total number of tracks as well as the type of each individual track can be found by calling getTrackInfo() method.

    getTrackInfo(java.lang.String)
  - deselectTrack
```
public void deselectTrack(int index)
```
