Unknown protocol: wss: in Socket.IO in Android

Question

Why is the

Socket mSocket = IO.socket("wss://engine_url:443/path_to_script);

returns the URISyntaxException: Unknown protocol: wss: exception

Any Idea why? Any help would be appreciated

Answer 1

Just use http:// or https:// . They are actually the same with ws:// and wss://

Answer 2
