I'm trying to make two android applications connected with TCP protocol.
Client has an imageView and when you push the button, it is supposed to send that image to the server and after server reads it, it is suppose to display the image.
but I haven't been able to display the sent image in server.
somebody could please give me a hand?

THIS IS MY SERVER CODE THAT GETS THE IMAGE AND IT IS SUPPOSE TO DISPLAY IT

package com.example.simpleserver;

        import java.io.DataInputStream;
        import java.io.IOException;
        import java.io.InputStream;
        import java.net.ServerSocket;
        import java.net.Socket;

        import android.app.Activity;
        import android.graphics.Bitmap;
        import android.graphics.BitmapFactory;
        import android.os.Bundle;
        import android.os.Handler;
        import android.os.Message;
        import android.widget.ImageView;
        import android.widget.TextView;

         public class SimpleServer extends Activity {
           ServerSocket ss = null;
           Thread myCommsThread = null;
           protected static final int MSG_ID = 0x1337;
           public static final int SERVERPORT = 6000;
           private Bitmap bitmap;

           @Override
          public void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_simple_server);
           TextView tv = (TextView) findViewById(R.id.textView01);
           tv.setText("Nothing from client yet");
           this.myCommsThread = new Thread(new CommsThread());
           this.myCommsThread.start();
           }

           @Override
           protected void onStop() {
           super.onStop();
           try {
                // make sure you close the socket upon exiting
               ss.close();
            } catch (IOException e) {
               e.printStackTrace();
            }
           }

           Handler myUpdateHandler = new Handler() {
            public void handleMessage(Message msg) {
                switch (msg.what) {
                    case MSG_ID:
                         ImageView tv = (ImageView) findViewById(R.id.imageViewServer);
                         tv.setImageBitmap(bitmap);
                         break;
                       default:
                           break;
                       }
                 super.handleMessage(msg);
             }
          };
           class CommsThread implements Runnable {
            public void run() {
               Socket s = null;
                try {
                ss = new ServerSocket(SERVERPORT );
            } catch (IOException e) {
                e.printStackTrace();
            }
            while (!Thread.currentThread().isInterrupted()) {
                Message m = new Message();
                m.what = MSG_ID;

                try {
                    if (s == null)
                        s = ss.accept();
                    InputStream in = s.getInputStream();
                    DataInputStream dis = new DataInputStream(in);

                    int len = dis.readInt();
                    byte[] data = new byte[len];
                    if (len > 0) {
                        dis.readFully(data);
                    }
                    bitmap = BitmapFactory.decodeByteArray(data , 0, data .length);
                    myUpdateHandler.sendMessage(m);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        }
        }

AND THIS IS MY CLIENT CODE THAT SENDS THE IMAGE

package com.example.simpleclient;

                ImageView iv=(ImageView)findViewById(R.id.imageView1);

                OutputStream out = socket.getOutputStream(); 
                DataOutputStream dos = new DataOutputStream(out);

                dos.writeInt(len);

                    dos.write(array, start, len);
                }

            }

            class ClientThread implements Runnable {

                    try {
