Switch the camera for video call (Android)

It is possible to switch the camera from the front to the main one and vice versa during the video call.
Keep in mind that the front camera is used by default.

In order to implement this functionality, you need to use CameraSwitchHandler.

First of all, you need to create a VideoCapturer instance.
Java:

QBRTCCameraVideoCapturer videoCapturer = (QBRTCCameraVideoCapturer) currentSession.getMediaStreamManager().getVideoCapturer(); videoCapturer.switchCamera(cameraSwitchHandler);

Kotlin:

val videoCapturer = currentSession.mediaStreamManager.videoCapturer as QBRTCCameraVideoCapturer videoCapturer.switchCamera(cameraSwitchHandler)

After that, you will need to create a CameraSwitchHandler instance, which will handle the camera switching process with onCameraSwitchDone and onCameraSwitchError methods.

Java:

CameraVideoCapturer.CameraSwitchHandler cameraSwitchHandler = new CameraVideoCapturer.CameraSwitchHandler() {
    @Override
    public void onCameraSwitchDone(boolean b) {


//   Your code here


    }

    @Override
    public void onCameraSwitchError(String s) {


//   Your code here


    }
};

val cameraSwitchHandler = object : CameraVideoCapturer.CameraSwitchHandler {
    override fun onCameraSwitchDone(b: Boolean?) {

//   Your code here

    }

    override fun onCameraSwitchError(s: String?) {

//   Your code here

    }
}
