I already have a iOS app that uses back4app as a backend. My app is similar to twitter/instagram. I already have sketches ready for the design. My iOS developer is working on a new version of the iOS app and you will have to build Android version from scratch with all the same features and works with existing database.
I need an Android social network expert with experience in Back4app.
Check out the document and send me links to your latest social network apps. I can show you current version of my iOS app.
