Android Installation

The simplest way of installing on Android is to use the react-native link CLI command & rebuild the project:

react-native link react-native-firebase

Manually

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

package com.youcompany.application;
// ...
import io.invertase.firebase.RNFirebasePackage;
// ...
public class MainApplication extends Application implements ReactApplication {
    // ...

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
          new RNFirebasePackage()  // <-- Add this line
      );
    }
  };
  // ...
}

We'll also need to list it in our android/app/build.gradle file as a dependency that we want React Native to compile. In the dependencies listing, add the compile line:

dependencies {
  compile project(':react-native-firebase')
}

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')

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 application props:

<application
  ...
  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>
