public interface Player
```
A media player interface defining traditional high-level functionality, such as the ability to play, pause, seek and query properties of the currently playing media.
This interface includes some convenience methods that can be implemented by calling other methods in the interface. BasePlayer implements these convenience methods so inheriting BasePlayer is recommended when implementing the interface so that only the minimal set of required methods can be implemented.
Some important properties of media players that implement this interface are:
- They can provide a Timeline representing the structure of the media being played, which can be obtained by calling getCurrentTimeline().
- They can provide a TracksInfo defining the currently available tracks and which are selected to be rendered, which can be obtained by calling getCurrentTracksInfo().

  - setPlaybackParameters
```
void setPlaybackParameters(PlaybackParameters playbackParameters)
```
    Attempts to set the playback parameters. Passing PlaybackParameters.DEFAULT resets the player to the default, which means there is no speed or pitch adjustment.
    Playback parameters changes may cause the player to buffer. Player.Listener.onPlaybackParametersChanged(PlaybackParameters) will be called whenever the currently active playback parameters change.
    
    Parameters:
    
    playbackParameters - The playback parameters.
  - setPlaybackSpeed
```
void setPlaybackSpeed(@FloatRange(from=0.0,fromInclusive=false)
                      float speed)

    Changes the rate at which playback occurs. The pitch is not changed.
    This is equivalent to setPlaybackParameters(getPlaybackParameters().withSpeed(speed)).
    
    Parameters:
    
    speed - The linear factor by which playback will be sped up. Must be higher than 0. 1 is normal speed, 2 is twice as fast, 0.5 is half normal speed...

    Calling this method will cause the playback state to transition to STATE_IDLE and the player will release the loaded media and resources required for playback. The player instance can still be used by calling prepare() again, and release() must still be called on the player if it's no longer required.
    Calling this method does not clear the playlist, reset the playback position or the playback error.
  - stop
```
@Deprecated

```
DeviceInfo getDeviceInfo()
```
    Gets the device information.
  - getDeviceVolume
```
@IntRange(from=0L)
int getDeviceVolume()
```
    Gets the current volume of the device.
    For devices with local playback, the volume returned by this method varies according to the current stream type. The stream type is determined by AudioAttributes.usage which can be converted to stream type with Util.getStreamTypeForAudioUsage(int).
    For devices with remote playback, the volume of the remote device is returned.
  - isDeviceMuted
```
boolean isDeviceMuted()
```
    Gets whether the device is muted or not.

```
void setDeviceVolume(@IntRange(from=0L)
                     int volume)
```
    Sets the volume of the device.
    
    Parameters:
    
    volume - The volume to set.
  - increaseDeviceVolume
```
void increaseDeviceVolume()
```
    Increases the volume of the device.
  - decreaseDeviceVolume
```
void decreaseDeviceVolume()
