This is a shopping app for our Program Structure class project at Ariel University. In this app a guest user can only view the file and if they want to make a purchase they need to sign up and log in. We used Firebase to sign up new users with their email address and for our products and shopping cart we use real time database.

How to get an APK

• Add git to your Android Studio
• In Android Studio: Build -> Build Bundle(s) / APK(s) -> Build APk(s)

Alternatively, you can always use the built in emulator.
