# 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:
```java
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:
```java
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](https://firebase.google.com/docs/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](https://inthecheesefactory.com/blog/understand-android-activity-launchmode/en) 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>
```
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>
```
