FireBase Implementation

FireBase Implementation

Step 1

go to firebase console website

login with google account

create new project by add project

enter project name

enable google analytics then continue

select / Choose account for analytics

create project

Step 2

Open created Project in firebase

select Development Type (Android , ios , Flutter , web etc...)

Firebase Setup for Android

Package Name

In Android Studio, open app module’s Gradle file:

Groovy: app/build.gradle
Kotlin DSL: app/build.gradle.kts

Copy the value of applicationId (your Package Name)

Paste it into Firebase console

Nickname

Give your app a cute little nickname so you can recognize it later

SHA-1 Key

Press Ctrl twice in Android Studio

Search for gradlew signingReport and run it in Terminal

Copy the SHA-1 from the output and paste it in Firebase

Register

Click Register App like a responsible adult

Add google-services.json

Download from Firebase

In Android Studio → Project view

Paste into: app/ folder

(the Android view hides it because it enjoys watching you suffer)

Add Firebase SDK

If your project uses Groovy build scripts

Project-level build.gradle → in dependencies:


classpath 'com.google.gms:google-services:4.4.0'

App-level build.gradle:


apply plugin: 'com.google.gms.google-services'

dependencies {
    implementation platform('com.google.firebase:firebase-bom:33.5.1')
    implementation 'com.google.firebase:firebase-analytics'
    implementation 'com.google.firebase:firebase-auth'
}

If your project uses Kotlin DSL `.kts` build scripts

Project-level build.gradle.kts:


plugins {
    id("com.google.gms.google-services") version "4.4.0" apply false
}

App-level build.gradle.kts:


plugins {
    id("com.android.application")
    id("com.google.gms.google-services")
}

dependencies {
    implementation(platform("com.google.firebase:firebase-bom:33.5.1"))
    implementation("com.google.firebase:firebase-analytics")
    implementation("com.google.firebase:firebase-auth")
}

Make sure repositories exist (if not, add):


dependencyResolutionManagement {
    repositories {
        google()
        mavenCentral()
    }
}

Sync Project

Gradle spins for a while

You pretend everything is under control

Internet Permission

Add this in AndroidManifest.xml above <application>:


<uses-permission android:name="android.permission.INTERNET" />
