Android获取Mac地址，支持android Q

1、声明权限

  <uses-permission android:name="android.permission.ACCESS_WIFI_STATE">  <uses-permission android:name="android.permission.INTERNET" />

2、调用代码
1） android 6.0以下可以通过获取wifi服务来获取Mac地址

/** * 获取wifi的mac地址，适配到android Q * @param paramContext * @return */public static String getMac(Context paramContext) {try {if (Build.VERSION.SDK_INT >= 23) {String str = getMacMoreThanM(paramContext);if (!TextUtils.isEmpty(str))return str;}// 6.0以下手机直接获取wifi的mac地址即可WifiManager wifiManager = (WifiManager)paramContext.getSystemService("wifi");WifiInfo wifiInfo = wifiManager.getConnectionInfo();if (wifiInfo != null)return wifiInfo.getMacAddress();} catch (Throwable throwable) {}return null;}

2）android 6.0+需要遍历网络接口来获取硬件地址，即mac地址

/** * android 6.0+获取wifi的mac地址 * @param paramContext * @return */private static String getMacMoreThanM(Context paramContext) {try {//获取本机器所有的网络接口Enumeration enumeration = NetworkInterface.getNetworkInterfaces();while (enumeration.hasMoreElements()) {NetworkInterface networkInterface = (NetworkInterface)enumeration.nextElement();//获取硬件地址，一般是MACbyte[] arrayOfByte = networkInterface.getHardwareAddress();if (arrayOfByte == null || arrayOfByte.length == 0) {continue;}StringBuilder stringBuilder = new StringBuilder();for (byte b : arrayOfByte) {//格式化为：两位十六进制加冒号的格式，若是不足两位，补0stringBuilder.append(String.format("%02X:", new Object[] { Byte.valueOf(b) }));}if (stringBuilder.length() > 0) {//删除后面多余的冒号stringBuilder.deleteCharAt(stringBuilder.length() - 1);}String str = stringBuilder.toString();// wlan0:无线网卡 eth0：以太网卡if (networkInterface.getName().equals("wlan0")) {return str;}}} catch (SocketException socketException) {return null;}return null;}
