Hello @haiyangwu, There is a problem with using this project

Hello @haiyangwu , I had the same problem and the server log displays 'mediasoup-demo-server:Room protoo Peer "close" event [peerId:79rkfrly] +8s'

[haiyangwu]

@pintukumarpatil @FlashMickeyMouse 🤔It works fine on my phone and emulator. Could you help me find the bug?

[pintukumarpatil]

Hello @haiyangwu I am sharing a test scenario, so you can find the bug easily.

1. After joined call, wait until WebSockets connection lost(WebSockets disconnect). Log on console WebSocketTransport: onClose() code: 3, reason: WebSockets connection lost and scheduleReconnect method will call for reconnect mWebSocketConnection.reconnect();
2. After reconnect the WebSocket, onOpen listener will call with joinImpl() method again(second time)
3. mediasoupDevice.load(data) will call second time And then crash the app.

@pintukumarpatil Thx for your advice, but I can't reproduce the crash. Cloud you please upload more logs about WebSocketTransport and RoomClient ?

Hello @haiyangwu

First join room in web app,and then join room in android and after that refresh web app.

i am sharing last logs:

@pintukumarpatil Thanks again, I got the error and it's a state error which hasn't been handled properly. But I had to solve this later, for now, I'm focusing on the Demo's UI.

Recently, I've added a lot of functions into RoomClient and rewritten the whole UI struct using MVVM + LiveData. This bug should be resolved now.

After onDisconnected from the server, RoomClient#closeTransportAndDevice would release the WebRtcAudioRecord. When websocket reopen, it would fine to recreate Device and invoke it's load function.

BTW, the dev branch still contains thread sync issues. 🤪
