Android Installation

1) Setup google-services.json

Download the google-services.json file provided by Firebase in the Add Firebase to Android platform menu in your Firebase configuration console. This file should be downloaded to YOUR_PROJECT/android/app/google-services.json.

Next you'll have to add the google-services gradle plugin in order to parse it.

Add the google-services gradle plugin as a dependency in the project level build.gradle android/build.gradle

buildscript {
  // ...
  dependencies {
    // ...
    classpath 'com.google.gms:google-services:3.0.0'
  }
}

In your app build.gradle file, add the gradle plugin at the VERY BOTTOM of the file (below all dependencies) android/app/build.gradle

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

2) Link RNFirebase

RNFirebase is split into separate modules to allow you to only include the Firebase functionality that you need in your application.

First add the project path to android/settings.gradle:

include ':react-native-firebase'
project(':react-native-firebase').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-firebase/android')

Now you need to include RNFirebase and the required Firebase dependencies in our android/app/build.gradle so that they are compiled as part of React Native. In the dependencies listing, add the appropriate compile lines:

dependencies {
  // RNFirebase required dependencies
  compile(project(':react-native-firebase')) {
    transitive = false
  }
  compile "com.google.firebase:firebase-core:11.0.4"

  // If you are receiving Google Play API availability issues, add the following dependency
  compile "com.google.android.gms:play-services-base:11.0.4"

  // RNFirebase optional dependencies
  compile "com.google.firebase:firebase-ads:11.0.4"
  compile "com.google.firebase:firebase-auth:11.0.4"
  compile "com.google.firebase:firebase-config:11.0.4"
  compile "com.google.firebase:firebase-crash:11.0.4"
  compile "com.google.firebase:firebase-database:11.0.4"
  compile "com.google.firebase:firebase-messaging:11.0.4"
  compile "com.google.firebase:firebase-perf:11.0.4"
  compile "com.google.firebase:firebase-storage:11.0.4"
}

To install react-native-firebase in your project, you'll need to import the packages you need from io.invertase.firebase in your project's android/app/src/main/java/com/[app name]/MainApplication.java and list them as packages for ReactNative in the getPackages() function:

package com.youcompany.application;
// ...
// Required package
import io.invertase.firebase.RNFirebasePackage; // <-- Add this line
// Optional packages - add as appropriate
import io.invertase.firebase.admob.RNFirebaseAdMobPackage; //Firebase AdMob
import io.invertase.firebase.analytics.RNFirebaseAnalyticsPackage; // Firebase Analytics
import io.invertase.firebase.auth.RNFirebaseAuthPackage; // Firebase Auth
import io.invertase.firebase.config.RNFirebaseRemoteConfigPackage; // Firebase Remote Config
import io.invertase.firebase.crash.RNFirebaseCrashPackage; // Firebase Crash Reporting
import io.invertase.firebase.database.RNFirebaseDatabasePackage; // Firebase Realtime Database
import io.invertase.firebase.messaging.RNFirebaseMessagingPackage; // Firebase Cloud Messaging
import io.invertase.firebase.perf.RNFirebasePerformancePackage; // Firebase Performance
import io.invertase.firebase.storage.RNFirebaseStoragePackage; // Firebase Storage
// ...
public class MainApplication extends Application implements ReactApplication {
    // ...

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
          new RNFirebasePackage(),  // <-- Add this line
          // Add these packages as appropriate
          new RNFirebaseAdMobPackage(),
          new RNFirebaseAnalyticsPackage(),
          new RNFirebaseAuthPackage(),
          new RNFirebaseRemoteConfigPackage(),
          new RNFirebaseCrashPackage(),
          new RNFirebaseDatabasePackage(),
          new RNFirebaseMessagingPackage(),
          new RNFirebasePerformancePackage(),
          new RNFirebaseStoragePackage()
      );
    }
  };
  // ...
}

3) Cloud Messaging (optional)

If you plan on using Firebase Cloud Messaging, add the following to android/app/src/main/AndroidManifest.xml.

Add permissions:

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

Set app launch mode inside activity props:

<activity
  ...
  android:launchMode="singleTop"
>

Add messaging service:

<application ...>
  <service
    android:name="io.invertase.firebase.messaging.MessagingService"
    android:enabled="true"
    android:exported="true">
      <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT" />
      </intent-filter>
  </service>
  <service android:name="io.invertase.firebase.messaging.InstanceIdService" android:exported="false">
    <intent-filter>
      <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
    </intent-filter>
  </service>

If you would like to schedule local notifications then you also need to add the following:

  <receiver android:name="io.invertase.firebase.messaging.RNFirebaseLocalMessagingPublisher"/>
  <receiver android:enabled="true" android:exported="true" android:name="io.invertase.firebase.messaging.RNFirebaseSystemBootEventReceiver">
    <intent-filter>
      <action android:name="android.intent.action.BOOT_COMPLETED"/>
      <action android:name="android.intent.action.QUICKBOOT_POWERON"/>
      <action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/>
      <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
  </receiver>

4) Performance Monitoring (optional)

If you'd like to take advantage of Firebase's Performance Monitoring, the following additions to your project setup are required:

In your projects android/build.gradle file, add the plugin to your dependencies:

dependencies {
  ...
  classpath 'com.google.firebase:firebase-plugins:1.1.0'
}

At the top of your android/app/build.gradle file, below other plugins, apply the firebase-perf plugin:

apply plugin: "com.android.application"
apply plugin: "com.google.firebase.firebase-perf"

In the same file, add the firebase-perf module to your dependencies:

dependencies {
  ...
  compile "com.google.firebase:firebase-perf:11.0.4"
}
