two android applications connected with TCP protocol

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;

        import java.io.DataOutputStream;
        import java.io.IOException;
        import java.io.OutputStream;
        import java.net.InetAddress;
        import java.net.Socket;
        import java.net.UnknownHostException;
        import java.nio.ByteBuffer;

        import android.app.Activity;
        import android.graphics.Bitmap;
        import android.graphics.drawable.BitmapDrawable;
        import android.os.Bundle;
        import android.view.View;
        import android.widget.ImageView;

        public class SimpleClient extends Activity {

            private Socket socket;

            private static final int SERVERPORT = 5000;
            private static final String SERVER_IP = "10.0.2.2";

            @Override
            public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_simple_client);
                new Thread(new ClientThread()).start();
            }

            public void onClick(View view) {
                try {;
                    getBytes();

                } catch (UnknownHostException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            public void getBytes() throws IOException{
                ImageView iv=(ImageView)findViewById(R.id.imageView1);
                //convert the image to bitmap to be send in the intent
                Bitmap bmp=((BitmapDrawable)iv.getDrawable()).getBitmap();
                int bytes = bmp.getByteCount();
                ByteBuffer buffer = ByteBuffer.allocate(bytes); //Create a new buffer
                bmp.copyPixelsToBuffer(buffer); //Move the byte data to the buffer

                byte[] array = buffer.array();
                int start=0;
                int len=array.length;
                if (len < 0)
                    throw new IllegalArgumentException("Negative length not allowed");
                if (start < 0 || start >= array.length)
                    throw new IndexOutOfBoundsException("Out of bounds: " + start);

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

                dos.writeInt(len);
                if (len > 0) {
                    dos.write(array, start, len);
                }

            }

            class ClientThread implements Runnable {

                @Override
                public void run() {

                    try {
                        InetAddress serverAddr = InetAddress.getByName(SERVER_IP);

                        socket = new Socket(serverAddr, SERVERPORT);

                    } catch (UnknownHostException e1) {
                        e1.printStackTrace();
                    } catch (IOException e1) {
                        e1.printStackTrace();
                    }

                }

            }
        }
