android webrtc VideoCapturerAndroid crashing due to applicationContext not set

I am implementing calling feature using webrtc. I successfully able to make voice calls. But video call providing error. Even I could not add the local stream through VideoCapturerAndroid. I searched all the references found by googling but none of them worked for my case. I changed the media constraints(video) according to supporting formats, but no luck. Please help me to solve the problem.

It is showing runtime exception applicationContext not set.

W/System.err: java.lang.RuntimeException: applicationContext not set.
W/System.err:     at org.webrtc.VideoCapturerAndroid.startCapture(VideoCapturerAndroid.java:499)

Full log is given below.

If you provide the code snippet you are using, it's easy to find the issue.

Below are steps to generate local video track from camera.

private VideoCapturer createCameraCapturer(CameraEnumerator enumerator) {
   final String[] deviceNames = enumerator.getDeviceNames();
   // First, try to find front facing camera
   Log.d(TAG, "Looking for front facing cameras.");
   for (String deviceName : deviceNames) {
     if (enumerator.isFrontFacing(deviceName)) {
       Log.d(TAG, "Creating front facing camera capturer.");
       VideoCapturer videoCapturer = enumerator.createCapturer(deviceName, null);
       if (videoCapturer != null) {
         return videoCapturer;
       }
     }
   }
   // Front facing camera not found, try something else
   Log.d(TAG, "Looking for other cameras.");
   for (String deviceName : deviceNames) {
     if (!enumerator.isFrontFacing(deviceName)) {
       Log.d(TAG, "Creating other camera capturer.");
       VideoCapturer videoCapturer = enumerator.createCapturer(deviceName, null);
       if (videoCapturer != null) {
         return videoCapturer;
       }
     }
   }
   return null;
 }

 VideoCapturer videoCapturer = createCameraCapturer(new Camera1Enumerator(captureToTexture()));
 VideoSource videoSource = factory.createVideoSource(videoCapturer);
 videoCapturer.startCapture(1200/*width*/, 720/*height*/, 25/*fps*/);

VideoTrack localVideoTrack = factory.createVideoTrack("NameYourTrack", videoSource);

Below code is to render the local video 

EglBase rootEglBase = EglBase.create(); 
SurfaceViewRenderer pipRenderer = (SurfaceViewRenderer) findViewById(R.id.pip_video_view); //You need define your UI element to render video 
pipRenderer.init(rootEglBase.getEglBaseContext(), null);
pipRenderer.setScalingType(ScalingType.SCALE_ASPECT_FIT);
localVideoTrack.setEnabled(true);
localVideoTrack.addRenderer(new VideoRenderer(pipRenderer));

Note: This code will work with latest WebRTC code base, if you are using old native library, you may need to update OR look for corresponding AppRTCMobile example.
