My socket is connected and want to receive message continuously?

[sovoereign]

I can receive a message when I connect to the socket. Once I connected to the socket, my server responds whenever something happens so how will I receive a message continuously.

If you look at this example https://github.com/crossbario/autobahn-java#websocket-on-android

Everytime your server sends a message, the onMessage callback will be called. So in your code, please make sure you have the onMessage callback.

@om26er Yes I have onMessage callback, but receiving a response when I connect to the server

   if(!connection.isConnected()){
                                connection.connect(getWssUrl(s_driver_api_key),otherStrings, new WebSocketConnectionHandler() {
                                    @Override
                                    public void onConnect(ConnectionResponse response) {
                                        System.out.println("Connected to server-----"+response);
                                    }

                                    @Override
                                    public void onOpen() {
                                        System.out.println("Connection onOpen------");
                                    }

                                    @Override
                                    public void onClose(int code, String reason) {
                                        System.out.println("Connection closed------"+code);
                                        System.out.println("Connection closed------"+reason);
                                    }

                                    @Override
                                    public void onMessage(String payload) {
                                        System.out.println("Received message:----- " + payload);
                                    }
                                });
                            }else{

                                System.out.println("Connected:----- " );

                            }

[om26er]

Is the websocket server public, maybe I can try to reproduce the issue (and debug, if needed). Is it possible for you to share the websocket URI ?

[sovoereign]

I want to receive message continuously, i can send message but not receiving after establishing connection but working fine with browser.

[om26er]

There is something very odd happening here. The server that you are trying to connect talks WAMPv1, this library now only supports WAMPv2. So I'd say this is a lost cause.

[om26er]

To elaborate on that. Autobahn Java only support WAMP protocol version 2. However, the server that you are trying to connect is only talks WAMP protocol version 1. Here is the screenshot of the errors. You can clearly see your server response returns this specific line in its response headers.

Sec-WebSocket-Protocol: wamp

[sovoereign]

@om26er okay got your point, but why does socket connect?

[oberstet]

the websocket opening handshake fails, since the websocket subprotocol negotiation runs into a mismatch. use a wamp2 server or use plain websocket
