Android Camera opening/closing
<p>I have written a video call application with Activity that has member variable
 private CameraMediaSource mCameraMediaSource;</p>

<p>Works fine but after a while sometimes camera does not show anymore.  Then I kill whole app and it works again. Not sure about how to handle the camera during activity lifecycle methods like onPause(), onResume() etc.  Does the cameera at some point need to be released?  How do I clear the camera, when it pauses a picture stays on the screen.  Thanks</p>
