Base on update from haiyangwu, this is my solution:

Firstly, Close() both send transport and receive transport
Secondly, dispose() them. It looks like Webrtc has thread async issue. If dispose before closing all, it becomes the issue.

I think I have fixed this problem. In the webrtc issues, there also have this problem. https://bugs.chromium.org/p/webrtc/issues/detail?id=7587 The reason is that only one audio device module supported on Android. In this code, when join the room, the peerConnectionFactory has been created 4 times and each time will create one audio device module.So I try to create only one peerConnectionFactory in java, and add peerconnection options params in device.cpp. Finally, it works. I hope it helps you.

Could you release a branch for us?
