# 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`
```java
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`
```java
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-analytics: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:
```java
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](https://firebase.google.com/docs/cloud-messaging/), add the following to `android/app/src/main/AndroidManifest.xml`.
Add permissions:
```xml
<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](https://inthecheesefactory.com/blog/understand-android-activity-launchmode/en) inside activity props:
```xml
<activity
...
android:launchMode="singleTop"
>
```
Add messaging service:
```xml
<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:
```xml
<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](https://firebase.google.com/docs/perf-mon/), 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:11.0.0"
}
```
