Question

I’m attempting to connect to a TCP socket in Android.

I know the socket service works because I can connect and interact with it in a browser (in JavaScript) as follows:

var ws = window.WebSocket || window.MozWebSocket;  
window.ws = new wsImpl('ws://foo.bar.com:8282/MySocketService', 'my-protocol');  
...

---

So, in my Android app:

This connects successfully, but I never receive messages from it:

SocketAddress sa = new InetSocketAddress("foo.bar.com", 8282);

This fails to connect:

SocketAddress sa = new InetSocketAddress("foo.bar.com/MySocketService", 8282);

and I receive an error like:

java.net.UnknownHostException: Host is unresolved: foo.bar.com/MySocketService:8282

Is there any way to indicate the application path for a TCP service?

Answer 1

TCP end-point is just IP address and a port number. What you are talking about is handled by upper-level protocols on top of TCP, like HTTP, so you need to look at other utilities like java.net.URL.
