aqui está o meu código completo: o cnx está estabelecido e estou enviando dados para o servidor, mas não consigo ler nada do servidor ...

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();
            }
        }
    }
