• The project requires Firebase. So follow the steps given here (Add Firebase to Android Project) to add firebase to your android project.
• Download the firebase config file google-services.json
• Move the config file to (app) module of the project.
• Also, add Cloud Firestore for storing users, products, orders and addresses data. Follow instructions here (Add Cloud Firestore to your app) to add Cloud Firestore to your app.
• There need to be two collections - users for Users data and products for Products Data.
• This project also, requires OTP based authentication. So, you just need to enable Phone Number sign-in in your firebase project. Follow instructions here (Enable Phone Number sign-in) to enable Phone Number sign-in.
• Do not forget to enable app verification for your firebase project. Follow instructions here (Enable app verification) to enable app verification. Add both SHA-1 and SHA-256 fingerprints.

Tried everything but still not able to explore the app due to OTP errors? Don't worry, you can by-pass the OTP screen and explore the app.

• Go to app/src/main/java/com/vishalgaur/shoppingapp/Utils.kt file.
• Change the return value for function shouldBypassOTPValidation() to true.
• You are good to go now. Just run the app and explore.
• And take your time to setup the OTP verification. 😉
