The below code results in a timeout.

It works fine on non-Android Java. What's the matter?

 //@Override
public static void run()
{
    //System.out.println ( "Local Machine IP : "+addrStr.toString (  )  ) ;
    HelloWorldActivity.tv.setText("Trace 1");

    try
    {
        // Retrieve the ServerName
        InetAddress serverAddr; //= InetAddress.getByName(Server.SERVERIP);
        InetAddress ias[] = InetAddress.getAllByName(Server.SERVERNAME);
        serverAddr  = ias[0];

        Log.d("UDP", "C: Connecting...");
        /* Create new UDP-Socket */
        DatagramSocket socket = new DatagramSocket();

        /* Prepare some data to be sent. */
        String strQuery="ÿÿÿÿgetservers"+" "+Server.iProtocol+" "+"'all'";
        Log.d("UDP", strQuery);
        //byte[] buf = ("ÿÿÿÿgetservers 68 'all'").getBytes();
        byte[] buf = strQuery.getBytes();

        /* Create UDP-packet with
         * data & destination(url+port) */
        DatagramPacket packet = new DatagramPacket(buf, buf.length, serverAddr, Server.SERVERPORT);

        Log.d("UDP", "C: Sending: '" + new String(buf) + "'");

        /* Send out the packet */
        socket.setSoTimeout(5000);
        socket.send(packet);
        Log.d("UDP", "C: Sent.");
        Log.d("UDP", "C: Done.");

        // http://code.google.com/p/android/issues/detail?id=2917

        byte[] buffer= new byte[1024*100];
        DatagramPacket receivePacket = new DatagramPacket(buffer, buffer.length); //, serverAddr, Server.SERVERPORT);
        socket.receive(receivePacket);
        HelloWorldActivity.tv.setText("TTT");

        String x = new String(receivePacket.getData());
        Log.d("UDP", "C: Received: '" + x  + "'");
        HelloWorldActivity.tv.setText(x);

   } catch (Exception e)
   {
       HelloWorldActivity.tv.setText(e.getMessage());
        Log.e("UDP", "C: Error", e);
   }

}
