套接字未在我的Android應用中連接

Question

我一直在服務器/客戶端應用程序中工作，該應用程序需要從計算機中工作的服務器獲取時間。

當我嘗試在手機中運行此應用時，它說SOCKET NOT CONNECTED。 我嘗試了一切，但仍然無法正常工作。

線程正在工作，但套接字未連接！

我使用的權限：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

MainActivity.java是：

package com.example.clientehora;

/* imports */


public class MainActivity extends Activity {

    Socket socket = new Socket();
    String SERVER_IP = "10.215.19.41";
    int SERVERPORT = 2000;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        new Thread(new ClientThread()).start();

    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }


    public void ejecutar(View view) {
        try {

            System.out.println("Hola amigo, si me presionaste! =D" + socket.getInetAddress() + socket.getPort());
            InputStream is = socket.getInputStream();
            BufferedReader br = new BufferedReader(new InputStreamReader(is));
            String cadena = br.readLine();
            System.out.println("LA CADENA ES: " +cadena);
            EditText et = (EditText)findViewById(R.id.fecha);
            et.setText(cadena);
            br.close();

        } catch (UnknownHostException e) {

            e.printStackTrace();

        } catch (IOException e) {

            e.printStackTrace();

        } catch (Exception e) {

            e.printStackTrace();

        }

    }



    class ClientThread implements Runnable {
        @Override
        public void run() {

            try {
                 System.out.println("Se ha conectado sin problemas");
                InetAddress serverAddr = InetAddress.getByName(SERVER_IP);
                socket = new Socket(serverAddr, SERVERPORT);

            } catch (UnknownHostException e1) {

                e1.printStackTrace();

            } catch (IOException e1) {

                e1.printStackTrace();

            }

        }

    }

}

這對我來說可以通過USB連接到Win7 PC（mTimeout為5000）：

mSocket = new Socket();
mSocket.setSoTimeout(mTimeout);
mSocket.connect(new InetSocketAddress(SERVER_IP, SERVERPORT), mTimeout);

我在PC上通過以下命令獲得要使用的IP：

InetAddress.getLocalHost().getHostAddress()
