Question

我一直在服务器/客户端应用程序中工作，需要从在我的计算机上工作的服务器获取时间。

当我尝试在手机中运行此应用程序时，它表示SOCKET未连接。我尝试了一切，但它仍然无法正常工作。

线程正在运行，但套接字没有连接！

我使用的权限：

<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();

            }

        }

    }

}

这适用于我通过USB连接到我的Win7 PC（mTimeout是5000）：

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

我在PC上使用此命令获取IP：

InetAddress.getLocalHost().getHostAddress()

套接字未在我的Android应用中连接
