I have developed an app for the school where I work. It is hosted on Google Play, but some of the students have Huawei phones without GMS. I would like them to have the option to download the
apk from the school's website. I can implement the notification logic, but I would like to know if a manual update keeps all the app's settings and cached data or not.
So if I notify the users about a new version, direct them to the website, make them download and install the new
apk, will they get a fresh installation of the app, or have all their user settings from the older version?
I know there are alternative stores, but it would be easier to handle it on my own, than forcing them to install a second app just to update the other one.
