从某加固软件里面抽取了一个工具类结果得到结果不一样

027rainguai

String iMei = DeviceInfoUtils.getIMEI(getContext());
                if (!TextUtils.isEmpty(iMei)) {
                    this.iMei = DeviceInfoUtils.getIMEI(getContext());
                } else {
                     this.iMei = "000000000000000";
                }
  String uniqueID = DeviceInfoUtils.getDeviceId(getContext());

  让后把 iMei 和 uniqueID 显示在界面上
某软件里面根据设备码来做授权验证，上面是 uniqueID 获取方法。 提取出来，打包到一个新apk 结果，和原来安装的那个需要破解的apk，获取到的不一致。这是个什么情况。
附上抽取出来的工具类

目测是签名不一样, AndroidId变了

无闻无问

如果静态找不到原因，就动态干，两边同时动态调试，一条一条比……
