# Configuring Audio, Video Input and Output devices - Android

In this guide we'll show you how to configure Audio, Video input and output devices from your Twilio Video Rooms API application. Taking advantage of the ability to control input and output devices lets you build a better end user experience.

## Selecting a specific Video Input

### CameraCapturer

The `CameraCapturer` provides video frames via the [Camera API](https://developer.android.com/guide/topics/media/camera) for a `LocalVideoTrack` from a given `CameraCapturer.CameraSource`.

```bash
// Share your camera
CameraCapturer cameraCapturer = new CameraCapturer(context, CameraSource.FRONT_CAMERA);
LocalVideoTrack localVideoTrack = LocalVideoTrack.create(context, true, cameraCapturer);
VideoView primaryVideoView = (VideoView) findViewById(R.id.local_video);

// Mirror front camera
primaryVideoView.setMirror(true);

// Render camera to view
localVideoTrack.addSink(primaryVideoView);

// Switch the camera source
CameraSource cameraSource = cameraCapturer.getCameraSource();
cameraCapturer.switchCamera();
primaryVideoView.setMirror(cameraSource == CameraSource.BACK_CAMERA);
```

### Camera2Capturer

The `Camera2Capturer` provides video frames via the [Camera 2 API](https://developer.android.com/reference/android/hardware/camera2/package-summary) for a `LocalVideoTrack` from a given camera ID.

```bash
// Get the device camera IDs
CameraManager cameraManager =
        (CameraManager) cameraCapturerActivity.getSystemService(Context.CAMERA_SERVICE);
String[] cameraIds = cameraManager.getCameraIdList();

// This example uses the first Camera ID but applications can make their own decisions
// about which Camera ID to use
String cameraId = cameraIds[0];

// Share your camera
Camera2Capturer camera2Capturer = new Camera2Capturer(context, cameraId, camera2Listener);
LocalVideoTrack localVideoTrack = LocalVideoTrack.create(context, true, camera2Capturer);

// Render camera to a view
VideoView primaryVideoView = (VideoView) findViewById(R.id.local_video);
localVideoTrack.addSink(primaryVideoView);

// Switch the camera source from the first camera ID to the second camera ID
camera2Capturer.switchCamera(cameraIds[1]);
```

## Managing Audio With AudioSwitch

The Twilio Video Android SDK does not officially support audio device management. Please use [AudioSwitch](https://github.com/twilio/audioswitch) to manage audio focus and audio devices in your application.
