Android通過TCP/IP連接到計算機

Question

我無法連接我的android模擬器到我的電腦。我可以發送信息給android，但發送回它只是失敗。

這是我到目前爲止有：

public class sendDataToRegion extends AsyncTask<String,Void,List<String> >{ 

     final TextView who = (TextView)findViewById(R.id.txtWho); 
     final TextView what = (TextView)findViewById(R.id.txtWhat); 
     final TextView when = (TextView)findViewById(R.id.txtWhen); 
     final TextView where = (TextView)findViewById(R.id.txtWhere); 
     final TextView actionTaken = (TextView)findViewById(R.id.txtActionTaken); 
     final TextView lengthOfTime = (TextView)findViewById(R.id.txtLengthOfTime); 

     public List<String> dataSend2 = new ArrayList<String>(); 


     @Override 
     protected List<String> doInBackground(String... params) { 
      try 
      { 
       System.out.println("Mobile Server Program"); 

       String whoString = who.getText().toString(); 
       String whatString = what.getText().toString(); 
       String whenString = when.getText().toString(); 
       String whereString = where.getText().toString(); 
       String actionString = actionTaken.getText().toString(); 
       String lengthString = lengthOfTime.getText().toString(); 

       dataSend2.add(whoString); 
       dataSend2.add(whatString); 
       dataSend2.add(whenString); 
       dataSend2.add(whereString); 
       dataSend2.add(actionString); 
       dataSend2.add(lengthString); 


       int port = 4444; 

       ServerSocket server = new ServerSocket(port); 

       Socket socket=server.accept(); 

       DataOutputStream network = new DataOutputStream(socket.getOutputStream()); 


       for(int i = 0; i< dataSend2.size();i++){ 
        network.writeUTF(dataSend2.get(i)); 
       } 


      } 
      catch (Exception e) { 

      Log.e("TCP", "S: Error", e); 

      } 

      return dataSend2; 
     } 

     protected void onPostExecute() { 
      System.out.println("Thread Finished " + dataSend2.size()); 


     } 

    }//End of inner class 

它儘可能創建服務器套接字得到，但沒有之後。有人能指出我正確的方向嗎？

感謝

UPDATE

這裏是客戶端：

try 
     { 

      String ip = "146.176.230.192"; 
      System.out.println("IP connected"); 

      int port = 4444; 
      System.out.println("port connected"); 

      // Connect to the server 
      Socket sock = new Socket(ip, port); 
      System.out.println("socket created"); 

      // Create the incoming stream to read messages from 
      DataInputStream network = new DataInputStream(sock.getInputStream()); 

      // Display our address 
      System.out.println("Address: " + sock.getInetAddress()); 
      String line; 

      while ((line = network.readUTF()) != null) 
      { 


       System.out.println(line); 
      } 



      sock.close(); 
     } 
     catch (IOException ioe) 
     { 
      System.out.println("Connection failed"); 


     }

使用的端口7612和運行您的程序之前運行此命令轉發端口：

adb forward tcp:7612 tcp:7612 

客戶端方：默認IP：127.0.0.1

服務器端：IP地址爲通配符地址

服務器端：

private ServerThread mServer; 
    .... 
    java.net.ServerSocket s = new java.net.ServerSocket(); 

// bind, only port used 
java.net.InetSocketAddressendPoint = new InetSocketAddress(port); 


    if(!s.isBound()){ 
    s.bind(7612); 
    } 
     .... 

客戶端

private   Socket mSocket; 
private static final int mConnectTimeout = 2500; // 2.5 seconds 

.... 
mSocket = new Socket(); 
InetSocketAddress remoteAddr = new InetSocketAddress(127.0.0.1, 7612); 
    mSocket.connect(remoteAddr, mConnectTimeout); 
.... 

ServerThread類

import java.io.IOException; 
import java.net.ServerSocket; 
import java.net.Socket; 



public class ServerThread implements Runnable{ 
public ServerThread(ServerSocket socket, OnConnectItf onConnect) // OnConnectItf is some callback 
    { 
    mServer = socket; 
    mCallback = onConnect; 
    mCancel = false; 
} 

public void cancel(){ 
    mCancel = true; 
} 


public void run() { 
    while (true){ 
     try { 
      Socket s = mServer.accept(); 
      if (mCancel == true) break; 

      .... 
     } 
     catch (IOException e) { 
      // optional: implement on error handler 
      break; 
     } 
    } 

    return; 
} 

private ServerSocket mServer; 
private OnConnectItf mCallback; 
private boolean  mCancel; 

}
