None of the Android demos seem to work for video, no error message.

For example, after launching the NativeCall example on an android device, I am able to join using a generated id but on calling (initiated by the device or by the google chrome user using the same id), the video is never sent. There is no error message. From what I have seen on the web, no one has been able to make these samples work for the las 2 years...

Start by reproducing the failure in the NativeCall example on an Android device, then compare a call initiated by the device with one initiated by a Google Chrome user using the same generated id. Trace why video is never sent and why no error is reported; done means Android video calls work and failures produce an actionable error message.
