Разъем Android Client, как читать данные?

Question

вот мой полный код: cnx установлен, и я отправляю данные на сервер, но я ничего не могу прочитать с сервера ...

public class client extends Activity
{
    /** Called when the activity is first created. */
    Socket sock;
    String spliter = "**";
    String mobileNbr = "100";
    String LastJOKEId = "-1";
    String spliterlast = "^^$$";
    BufferedReader inFromServer;
    DataOutputStream outToServer;
    TextView cnx;
    TextView output;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        setupNetworking();
        // Thread readerThread=new Thread(new IncomingReader());
        // readerThread.start();
    }

    private void setupNetworking()
    {
        try
        {
            Log.i("ClientActivity", "Connecting...");
            sock = new Socket("192.168.153.221", 9003);
            cnx = (TextView) findViewById(R.id.textView1);
            cnx.setText("Network Established.");
            inFromServer = new BufferedReader(new InputStreamReader(sock.getInputStream()));
            Log.i("ClientActivity", "Sending command.");
            outToServer = new DataOutputStream(sock.getOutputStream());
            String sentence = "logins" + spliter + mobileNbr + spliter + LastJOKEId + spliterlast;
            outToServer.writeBytes(sentence + '\n');
            Log.i("ClientActivity", "Sent.");
        }
        catch (UnknownHostException e)
        {
            e.printStackTrace();
        }
        catch (IOException e)
        {
            cnx = (TextView) findViewById(R.id.textView1);
            cnx.setText("Network failed");
            e.printStackTrace();
        }
    }

    public class IncomingReader implements Runnable
    {
        String message;
        public void run()
        {
            try
            {
                while ((message = inFromServer.readLine()) != null)
                {
                    output = (TextView) findViewById(R.id.textView2);
                    output.setText(message);
                }
            }
            catch (IOException e)
            {
                output = (TextView) findViewById(R.id.textView2);
                output.setText("nth to display");
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
}

HttpResponse response = m_httpClient.execute( request );
String result = "";
if( response.getStatusLine().getStatusCode() == HttpStatus.SC_OK )
{
// open stream
      InputStream stream = response.getEntity().getContent();

      if( stream != null )
      {
        int len = 0;
        byte[] buf = new byte[ 1024 ];

        try
        {
          ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

          while( ( len = stream.read( buf ) ) > 0 )
          {
            outputStream.write( buf, 0, len );
          }

          buf = outputStream.toByteArray();
          result = EncodingUtils.getAsciiString( buf );
        }
        catch( IOException e )
        {
          e.printStackTrace();
        }
        finally
        {
          stream.close();
        }
}
