title: switch camera(back/front) in android webrtc
body: <p>I have used libjingle library for webrtc android application. I have successfully implemented audio video streaming for two way communication. </p>
  
  <p>Till now i was using front camera for video streaming but now <strong>i want to put option for users to select front or back camera for video streaming</strong>.</p>
