android获取设备唯一标识

这里列举了获取所有可以获取到的设备唯一识别码：getDeviceId()。
我的设备是TV，获取不到IMEI，但是有以太网口，所以最好的办法是获取以太网mac作为唯一标识。

public class MobileInfoUtil {

    private static String wifiTag = "wlan0";//无线标志，关闭wifi开关后获取不到
    private static String localTag = "eth0";//有线标志,插不插网线都能获取到

            if(!isEmpty(wifiMac) && !"02:00:00:00:00:00".equals(wifiMac)){
                deviceId.append("wifi");
