switch camera using MediaDevices.getUserMedia() in webrtc

I am trying navigator.MediaDevices.getUserMedia() webrtc to switch the device camera during the call. This functionality is working fine on the desktop browser but on mozilla android it is not working. Here is my code that i am using .

var front=false;

var myConstraints = {  video: { facingMode: (front? "user" : "environment")} }; 
navigator.mediaDevices.getUserMedia(myConstraints).then(function(stream) {

}

any idea about this??

Webcam.set({
        width: 490,
        height: 450,
        image_format: 'jpeg',
        jpeg_quality: 90,
        constraints: {
                    facingMode: {
                                  exact: 'environment'
                                  }

                }   
    });

This code is working for all browsers. 

constraints: {facingMode: { exact: 'environment' }}

Above line is responsible to open rear camera, set constraints : null to open front camera. you can also adjust this code by implementing "switch camera" button method

use the last version of adapter.js and see if NotReadableerror is happening, it seems that Chrome for android cannot release front camera hardware to switch to rear by using stream.getVideoTracks()[0].stop(); I think it could be a bug

Phone hardware typically doesn't allow opening both the front and back camera at the same time. Change your code to stop() the existing stream before getting the other camera.

See my answer to a similar question for a working example.
