android studio中的Socket Python-Server和Java - Client，java无法连接到python服务器

import socket

# 创建socket对象
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 绑定IP地址和端口号
server_socket.bind(('服务器IP地址', 8888))

# 监听连接
server_socket.listen(1)

# 等待客户端连接
client_socket, client_address = server_socket.accept()

# 接收客户端消息
data = client_socket.recv(1024).decode()
print('接收到客户端消息：', data)

# 关闭连接
client_socket.close()
server_socket.close()

import java.io.*;
import java.net.*;

public class Client {
    public static void main(String[] args) {
        try {
            // 创建Socket对象，指定服务器的IP地址和端口号
            Socket socket = new Socket("服务器IP地址", 8888);

            // 发送数据给服务器
            OutputStream outputStream = socket.getOutputStream();
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream));
            writer.write("Hello from Java client");
            writer.flush();
            System.out.println("消息发送成功");
