Add Message Dependency in your gradle file to implement Firebase Push Notification

implementation 'com.google.firebase:firebase-messaging:17.5.0'

 

Add Service to Manifest.xml

<service
    android:name=".notification.MyFirebaseInstanceIDService"
    android:exported="true">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT" />
    </intent-filter>
</service>

 

public class MyFirebaseInstanceIDService extends FirebaseMessagingService {

    @Override
    public void onNewToken(String token) {
        super.onNewToken(token);
        Log.d("TAG", "Refreshed token: " + token);
    }
}

 

Create FirebaseMessageingService.java
