Question

我刚接触socket编程，我正在开发一个程序，用于在手机上运行的Android应用程序，以便根据我的机器与我的serlet进行通信。我得到一个例外说套接字已关闭。 servletside

 private ServerSocket serverSocket;
   public static final int SERVERPORT = 8080;
Socket socket=null; 
         serverSocket = new ServerSocket(SERVERPORT);
        socket = serverSocket.accept();
        InputStream is =socket.getInputStream();
        DataInputStream dis =new DataInputStream(is); 
         String input = dis.readUTF();
        data1 = dis.readUTF();
        System.out.println(input+"            "+data1);
      OutputStream dout=socket.getOutputStream();
      DataOutputStream dat = new DataOutputStream(dout);
      dat.writeUTF("Hello to you too");
      dat.close();

应用方

private Socket socket;
     private static final int SERVERPORT = 8080;
     private static final String SERVER_IP = "192.168.1.8";
 InetAddress serverAddr = InetAddress.getByName(SERVER_IP);
                        socket = new Socket(serverAddr, SERVERPORT);
                        DataOutputStream out1 = new DataOutputStream(socket.getOutputStream());
                        out1.writeUTF(ip);
                        out1.writeUTF(mac);
                     out1.close();
                     Log.d("Message","WTF");
                        InputStream is =socket.getInputStream();
                        DataInputStream dis =new DataInputStream(is); 
                        while(dis.available()==0);
                       Log.d("Message","came here 2");
                       String WTF = dis.readUTF();
                       dis.close();
                       Log.d("Message",WTF);

尝试将下一行放在Manifest上;

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

使用servlet的android和servlet通信
