Re: [android-developers] ServerSocket problem

do you know what's the ip address you got on the real device.

There are chances the real device is on NAT network. In such a case you wont be able to talk directly to the device.

Hi, folks

I'm now facing a very strange server socket problem, I have a server that will listen on a TCP port, I use the following code to do this work.

public class RequestListenerThread extends Thread {

private final ServerSocket serversocket;

public RequestListenerThread(int port, final String docroot)

throws IOException {

this.serversocket = new ServerSocket(port);

setDaemon(true);

}

public void run() {

Log.v("FE", "SMB Server Listening on port "

+ this.serversocket.getLocalPort());

while (!Thread.interrupted()) {

try {

// Setup incoming client connection

Socket socket = this.serversocket.accept();

Log.v("FE", "Incoming connection from "

+ socket.getInetAddress());

// Start worker thread

Thread t = new WorkerThread(socket);

t.start();

} catch (InterruptedIOException ex) {

break;

} catch (IOException e) {

Log.v("FE", "Network I/O error: "

+ e.getMessage());

break;

}

}

}

    }

My target device is running on Android 1.6.

When I run this code, it can start to listen on port but can't accept any incoming connections. When it runs into serversocket.accept function, it never return, just like dead lock. 

Does anybody has the same issue? How do you solve this problem?

Thanks very much

Alex
