title: java.lang.AssertionError: Expected condition to be true webrtc android
body: <p>I am implementing webrtc in android using libjingle (version-9127), the issue is that in one application life cycle when I try to make calls, then the first call is successfully established and then ended. But when second call is made then when the call gets pickup then , the video is displayed , but audio stream is not transferred and then after 3-7 sec the app crashes giving this error.
  The complete logcat error is below:</p>

  <p><strong>Edit</strong>: To disconnect the call I have made this code. Hope you can figur out what the error is. After this I am releasing peerConnections</p>
  
  <pre><code>if(mediaStream != null  &amp;&amp; isLocal) {
  
          mediaStream.removeTrack(audioTrack);
