问题描述
Android开发寻求获得在Android M上的无线MAC地址可能经历的地方标准Android OS API获取MAC地址返回一个错误的MAC地址（02：00：00：00：00：00）的问题，而不是真正的价值。
Android developers looking to get the Wifi MAC Address on Android M may have experienced an issue where the standard Android OS API to get the MAC Address returns a fake MAC Address (02:00:00:00:00:00) instead of the real value.
正常的方式来获得无线MAC地址如下：

final WifiManager wifiManager = (WifiManager) getApplication().getApplicationContext().getSystemService(Context.WIFI_SERVICE);
final String wifiMACaddress = wifiManager.getConnectionInfo().getMacAddress();

推荐答案
解决！
MAC地址仍然可以从路径抓起：
The MAC Address can still be grabbed from the path:
"/sys/class/net/" + networkInterfaceName + "/address";
简单地做一个文件的读取，或该文件的猫会显示无线MAC地址。
Simply doing a file read, or a cat of that file will show the Wifi MAC Address.
网络接口名称通常是沿着为wlan0或eth1的
Network interface names are usually along the lines of "wlan0" or "eth1"
