Android TCP客户端服务 - 没有工作

Question

我正在制作一个通过TCP与不同活动中的java服务器连接的应用程序，所以在这里阅读最佳做法是使用Android服务。

这是我写的第一个套接字代码所以我真的不知道我在做什么

我在手机中的pc和app中使用netbeans运行服务器，但它不起作用，我的错误是什么？

ip地址是我的电脑运行服务器的私人IP，因为我在我的手机中运行应用程序

这是服务器代码

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;
import java.io.*;
import java.net.*;


public class Server {

public static void main(String[] args) throws Exception {


        String clientSentence;
        String capitalizedSentence;
        ServerSocket welcomeSocket=new ServerSocket(1001);

        while(true){
            Socket connectionSocket = welcomeSocket.accept();
            BufferedReader inFromClient = new BufferedReader(new InputStreamReader(connectionSocket.getInputStream()));
            DataOutputStream outToClient = new DataOutputStream(connectionSocket.getOutputStream());
            clientSentence = inFromClient.readLine();
            System.out.println("Received: "+clientSentence);
            capitalizedSentence = clientSentence.toUpperCase()+"\n";
            outToClient.writeBytes(capitalizedSentence);
        }


    }
}

这是我服务的代码

        return PlacesToShow;
    }



    public class LocalBinder extends Binder {
        ConnectionService getService(){
            return ConnectionService.this;
        }
    }
}

这是我调用测试方法的代码。 在onCreate方法中调用了methos，之前调用的方法正在工作。
