- Method Detail
  - onAudioDeviceListChanged
```
void onAudioDeviceListChanged(java.util.List<AudioDevice> newDeviceList,
                              boolean activeDeviceChanged)
```
    Audio device(s) have been added or removed by the system. This can be due to a Bluetooth device (dis)connecting or a headset being plugged in.
    
    Parameters:
    
    newDeviceList - updated device list with new device(s) added or removed.
    
    activeDeviceChanged - true if the current active device has changed. If this is true then the audio has moved to a safe state and is muted. A calling setUserRequestedDevice will cause the audio to be restored on the new device. gatActiveDevice() can be called to see what is the currently active device.
  - onAudioDeviceChanged

```
    Called when the active audio device has changed via the AudioInterface API. The callback occurs after the device becomes active, i.e., for Bluetooth after the SCO connection is established.
    
    Parameters:
    
    newDevice - new active device.
  - onAudioDeviceError
```
void onAudioDeviceError(AudioDeviceError error)
```
