Now add google-services.json file to your project by using this file firebase push notifications services can be implemented in your app not only push notifications even analytics, login, data storage, and many ore services can be implemented based on this json file.

 

We are not adding any element in the layout file.

 

MainActivity :

We will be initializing the app using firebase and fetch the token which can be used to receive firebase push notifications.Based on the token devices are identified.

 

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Log.d(TAG, "Refreshed token: " + FirebaseInstanceId.getInstance().getToken());
    }
}

 

FcmService :

Using the FCM service we can fetch the latest token and can use it to continue using Firebase Push Notifications also update it to the database.

 

public class FcmService extends FirebaseInstanceIdService{

    @Override
    public void onTokenRefresh() {
        // Get updated InstanceID token.
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.d(TAG, "Refreshed token: " + refreshedToken);

    }

}

 

AndroidManifest.xml :

Need to specify the service in manifest file to make it start working with firebase push notification.

 

 

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="push.android.com.androidpushnotifications">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>


        <service
            android:name=".FcmService">
            <intent-filter>
                <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
            </intent-filter>
        </service>

    </application>

</manifest>
