如何使用Socket将图片从PC发送到Android？

import java.io.File;
import java.io.FileInputStream;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class Server {
    public static void main(String[] args) {
        try {
            // 创建服务器端Socket，监听指定端口
            ServerSocket serverSocket = new ServerSocket(8888);
            
            System.out.println("等待Android端连接...");
            
            // 等待Android端连接
            Socket socket = serverSocket.accept();
            
            System.out.println("Android端已连接");
            
            // 读取图片文件为字节流
            File file = new File("path/to/image.jpg");
            FileInputStream fileInputStream = new FileInputStream(file);
            byte[] buffer = new byte[(int) file.length()];
            fileInputStream.read(buffer);
            
            // 发送字节流给Android端
            OutputStream outputStream = socket.getOutputStream();
            outputStream.write(buffer);
            
            System.out.println("图片已发送");
            
            // 关闭连接
            fileInputStream.close();
            outputStream.close();
            socket.close();
            serverSocket.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.net.Socket;

public class Client {
    public static void main(String[] args) {
        try {
            // 创建客户端Socket，连接到服务器端
            Socket socket = new Socket("PC的IP地址", 8888);
            
            // 接收服务器端发送的字节流
            InputStream inputStream = socket.getInputStream();
            byte[] buffer = new byte[1024];
            int bytesRead;
            
            // 创建图片文件
            File file = new File("path/to/save/image.jpg");
            FileOutputStream fileOutputStream = new FileOutputStream(file);
            
            // 将字节流写入图片文件
            while ((bytesRead = inputStream.read(buffer)) != -1) {
                fileOutputStream.write(buffer, 0, bytesRead);
            }
            
            System.out.println("图片已接收");
            
            // 关闭连接
            fileOutputStream.close();
            inputStream.close();
            socket.close();
        } catch (Exception e) {
