推荐答案
UUID(通用唯一标识符)基于每个应用程序。标识设备上的应用。只要用户没有完全删除应用程序,那么此标识符将在应用程序启动之间保持不变,并且至少允许您使用设备上的特定应用程序识别同一用户。不幸的是,如果用户完全删除并重新安装应用程序,则ID将会更改。

As long as the user doesn’t completely delete the app, then this identifier will persist between app launches, and at least let you identify the same user using a particular app on a device. Unfortunately, if the user completely deletes and then reinstalls the app then the ID will change.
