How to get multiple parameters in server response.

[humanfriend22]

I am creating an android app with auth and I send data to authorize on my Socket.io Server. I can send the data and handle it on my server just fine, but the server response is where I am getting an error. My server responds with something like this:

socket.emit("authUser-res", 'invalid_credentials',  '_error');

I can listen to the event on the client and read the first parameter just fine, but when I try to read the second one, I get a java.lang.ArrayIndexOutOfBoundsException error. My java event-listener on the client:

client.on("authUser-res", new Emitter.Listener() {
            public void call(Object... res) {
                String message = (String) res[0];
                String userName = (String) res[1];
                authUserServerResponse(message, userName);
            }
        });

When reading res[1], I get this full error:

Please Help, I need two parameters for my app to function the planned way.

Thank you in advance.
