AudioPlayer

```
public class AudioPlayer

                    
```
An AudioPlayer that uses the ExoPlayer as the backing architecture. If the current device does NOT pass the Android Compatibility Test Suite (CTS) then the backing architecture will fall back to using the default Android MediaPlayer.
To help with quick conversions from the Android MediaPlayer this class follows the APIs the Android MediaPlayer provides.
