Hi all,



I've implemented the Google Analytics successfully. That's great! But what is my issues then?


I want to know the back data collection and storage structure/framework of Google Analytics for generating reports, that how each users information is stored(i.e. Either by user id or by client id). And what if I change/update the main Client ID of the app? or What if user clear cache/data/uninstall of android app do the user get the same previous user id or newly generated? Can store user email as user id or not?


Please reply me ASAP.


Thank you


Regards ,
