Setting up Firebase for your KiviLabs Project

Create A New Firebase Project

1. We are creating the “Example” sample project.

2. After completing the project, you will be presented with this type of dashboard.

3. Go to the Project Settings and configure the Support Email.

Add App With The Package Name In Firebase Console

1. On the Firebase console, click the Android icon.

2. Enter Package Name (e.g., com.example.userApp) and click on register app.

3. After registering the app, you will receive the Google JSON file, download it and save it to the android/app/ folder.

Set Up Firebase Authentication

1. Go to Build -> Authentication tab and click on Get started.

2. Then select the Email/Password, Google, Apple one by one and enable them.

3. Re-check if all these 3 modes of authentication are enabled or not.

Activating The Firestore Database

1. Go to Build → Firestore Database tab and click on Get Started.

2. When you click the Get Started button, a dialogue will appear asking you to Sand mode and Production mode.

3. Change the Firestore’s rules to save the data in a database.

Updated rules:

 rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
  
    // Users Collection (Manages roles)
    match /users/{userId} {
      allow read, write: if request.auth != null && request.auth.uid == userId;
    }
    
    // Allow collectors to manage their own location
    match /collector_locations/{appointmentId} {
      allow read, write: if request.auth != null;
    }
  }
}

Note

The collector’s location is stored in Firestore and fetched in the customer app for real-time tracking. Firestore rules ensure data security and restrict access to authorized users only.

SHA Fingerprint

INFO

SHA-1 fingerprint is a unique key generated for your PC that can be used for signing. It is important to have in the add Firebase as we are using Google Login and OTP Login, and to authorize these logins, we need a SHA Fingerprint certificate

• In your Project settings, go to the Your apps card.

• Select the Firebase Android app to which you want to add a SHA fingerprint.

• Click Add fingerprint.

• Enter or paste the SHA fingerprint, then click Save.
