关于 Android 更新时的 UUID 行为网上没有太多文档，但您可以查看 This answer
- In some rare circumstances, this ID may change. In particular, if the device is factory reset a new device ID
- may be generated. In addition, if a user upgrades their phone from certain buggy implementations of Android 2.2
- to a newer, non-buggy version of Android, the device ID may change. Or, if a user uninstalls your app on
- a device that has neither a proper Android ID nor a Device ID, this ID may change on reinstallation.
