Android 10:如何在没有/proc/net/arp的情况下从Socket / Client PC获取MAC地址

import java.net.*;
import java.util.*;

public class GetMacAddress {
    public static void main(String[] args) {
        try {
            Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
            while (interfaces.hasMoreElements()) {
                NetworkInterface networkInterface = interfaces.nextElement();
                if (isSocketClientPC(networkInterface)) {
                    byte[] mac = networkInterface.getHardwareAddress();
                    if (mac != null) {
                        StringBuilder sb = new StringBuilder();
                        for (int i = 0; i < mac.length; i++) {
                            sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
                        }
                        System.out.println("MAC Address: " + sb.toString());
                        break;
                    }
                }
            }
        } catch (SocketException e) {
            e.printStackTrace();
        }
    }

    private static boolean isSocketClientPC(NetworkInterface networkInterface) throws SocketException {
        // 根据实际情况判断是否为Socket/Client PC所在的网络接口
        // 可以根据网络接口的IP地址、名称、描述等进行判断
        return networkInterface.getName().equals("eth0");
    }
}
