android 6.0及以下获取wifi mac地址

Android 获取wifi mac地址的方法

Android 6.0以下获取mac地址的方法如下：

 WifiManager mWifi = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);            if (mWifi.isWifiEnabled()) {                WifiInfo wifiInfo = mWifi.getConnectionInfo();                macAddress = wifiInfo != null ? wifiInfo.getMacAddress() : "";            }

但是在6.0及以上设置了权限，上面的方法获取的wifi mac 为默认值 “02:00:00:00:00:02”，可以用如下的方法获取

String macAddress = null;            StringBuffer buf = new StringBuffer();            NetworkInterface networkInterface = null;            try {                networkInterface = NetworkInterface.getByName("wlan0");                if (networkInterface == null) {                    return "02:00:00:00:00:02";                }                byte[] addr = networkInterface.getHardwareAddress();                for (byte b : addr) {                    buf.append(String.format("%02X:", b));                }                if (buf.length() > 0) {                    buf.deleteCharAt(buf.length() - 1);                }                macAddress = buf.toString();            } catch (SocketException e) {                e.printStackTrace();                return "02:00:00:00:00:02";            }
