1.获取硬件MAC地址

public String getMACaddress() {
  WifiManager wifiManager = (WifiManager) mContext.getSystemService(Context.WIFI_SERVICE);
  final String[] macAddresses = wifiManager.getFactoryMacAddresses();
  String macAddress = "";
       if (macAddresses != null && macAddresses.length > 0) {
           macAddress = macAddresses[0];
       }
       return macAddress;
}

2.获取​​WLAN​​ MAC地址

public String getWlanMACaddress() {
  WifiManager wifiManager = (WifiManager) mContext.getSystemService(Context.WIFI_SERVICE);
  WifiInfo wifiInfo = wifiManager.getConnectionInfo();
  String macAddress = wifiInfo == null ? null : wifiInfo.getMacAddress();
  return macAddress;
}
