OpenTok was unable to add video for the subscriber after establishing a session on the Cordova Android device

Question

Problem

The subscriber video for the device is not added to the dom element after establishing an OpenTok session.

Expected Behavior

After OpenTok sessionreceives the event streamCreated:

• subscription to the session event.stream,
• passing in the dom target,
• Subscriber Properties
• providing callback

must initialize the subscriber stream and fill the provided dom element with the video stream or fail if an error occurs during the subscription process.

this.session.on({
    streamCreated: event => {
        console.log('----- Event Stream: ', event.stream);

        let subscriberProperties = {
            width: '100%',
            height: '100%',
            insertMode: 'append'
        };

        this.subscriber = this.session.subscribe(event.stream, 'subscriberContainer', subscriberProperties, err => {
            if (err) {
                console.log('----- Subscriber subscribe error: ', err);
            }
            else {
                console.log('----- Subscriber added.....');
            }
        });
    }
});

Actual behavior

streamCreatedtriggered and a thread is created. OpenTok issues a warning:

RTCIceServer.url is deprecated, please use RTCIceServer.urls instead.

The following are these errors:
