无法通过套接字接收图像

Question

im tryin to send an image over socket , the sender part -(android)- looks short and ok, but the receiver part - which is written by java - is supposed to rename the image and save it in the C:/... . but i get nothing there and i cant find any problem with it ..

here is my server code:

public void start() throws InterruptedException {
    keepGoing = true;
    try 
    {

       // the socket used by the server
       ServerSocket serverSocket = new ServerSocket(port);

       // infinite loop to wait for connections
       while(keepGoing) 
       {
           // format message saying we are waiting
           display("Server waiting for Clients on port " + port + ".");

           Socket socket = serverSocket.accept(); // accept connection
           // if I was asked to stop

           if(!keepGoing)
            break;
           ClientThread t = new ClientThread(socket); // make a hread of it
           jobdone=false;
           al.add(t); // save it in the ArrayList
           t.start();
        }
        // I was asked to stop
        try {
            serverSocket.close();
            for(int i = 0; i < al.size(); ++i) {
                ClientThread tc = al.get(i);
                try {
                tc.sInput.close();
                tc.sOutput.close();
                tc.socket.close();
                }
                catch(IOException ioE) {
                    // not much I can do
                }
            }
        }
        catch(Exception e) {
            display("Exception closing the server and clients: " + e);
        }
    }
    // something went bad

                 String msg = sdf.format(new Date()) + 
                    " Exception on new ServerSocket: " + e + 
                    "\n";
         display(msg);
    }
}       
/*

    keepGoing = false;
    // connect to myself as Client to exit statement 
    // Socket socket = serverSocket.accept();
    try {
        new Socket("192.168.1.2", 1500);
    }
    catch(Exception e) {
        // nothing I can really do
    }
}
