I made an android app using Firebase as the main database, specifically the RealtimeDatabase. I've handled the authentication of the users with Firebase authentication.
Thanks to those who advised me to include a better description of the problem (i'm new here).
I built an app with android studio and connected it to firebase realtime database. Is an app that is used to share gift lists, users access the app and can send each other their lists and view them from the app. The problem arises when a user shares the list with those who do not have the app: i would like a link to be generated, showing a web version of the list, where the app actions are still available (which obviously are actions involving the use of firebase). I don't know how to do it...
