Add the library to your application class (e.g. `MainApplication.java`):
```java
import com.wix.reactnativenotifications.RNNotificationsPackage;
...
@Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new MainReactPackage(),
// ...
// Add this line:
new RNNotificationsPackage(MainApplication.this)
);
```
### Receiving push notifications
> Note: This section is only necessary in case you wish to be able to **receive** push notifications in your React-Native app.
Push notifications on Android are managed and dispatched using [Google's FCM service](https://firebase.google.com/docs/cloud-messaging). The following installation steps are a TL;DR of [Google's FCM setup guide](https://firebase.google.com/docs/cloud-messaging/android/client). You can follow them to get FCM integrated quickly, but we recommend that you will in the very least have a peek at the guide's overview.
#### Step #1: Subscribe to Google's FCM
To set FCM in your app, you must first create a google-services.json file. If you have no existing API project yet, the easiest way to go about in creating one is using [this step-by-step installation process](https://firebase.google.com/docs/android/setup);
#### Step #2: Copy google-services.json
After creating google-services.json, copy it into your project's android/app folder.
#### Step #3: Add google-services package to Project/build.gradle
```gradle
buildscript {
...
dependencies {
...
classpath 'com.google.gms:google-services:4.0.0'
}
}
```
#### Step #4: Add firebase-core package and apply google-services plugin in Project/app/build.gradle
```gradle
dependencies {
...
implementation 'com.google.firebase:firebase-core:16.0.0'
}
apply plugin: 'com.google.gms.google-services'
```
