I need a working sample of an android app that uses WebRTC technology.
Criteria - the app will not use any third party credentials which may incur cost in the future. It should be peer to peer calling/sharing. Firebase can be used for signalling.
Complete and error-free fully fuctional code of the android app.
The app should do video/audio calling and file sharing using WebRTC technology.
Firebase can be used signalling. Microsoft Azure server can also be used for signalling.
There is no preference towards look and feel of the app at user end. It can be very basic.
There should be no additional functionality except video/audio calling and file sharing. Additional functionalities will clutter the codes and make it difficult for me to read them.
