SocketIO disconnection cannot be detected when device is connected to a non-functional network

[jondwillis]

After successfully connecting to SocketIO on a working connection, if that connection fails to communicate further with SocketIO, I don't see a way to detect any malfunction.

DisconnectCallback is never called, and SocketIOClient.isConnected() is always true along with SocketIOClient.getWebSocket().isOpen() and SocketIOClient.getWebSocket().getSocket().isOpen().

Am I missing something?

I could occasionally try to ping my server, but that isn't ideal.
