Packaging for Android

To package your project for Android, make sure you have your google-services.json file in the root directory.

Now open up the Plugins window in Unreal Engine and make sure the plugin is installed.

When that is verified, go to the Project Settings in Unreal, now scroll down until you see the Android tab. 

Now scroll up to the Android Package Name section.

Make sure, it matches the name in Firebase.

Firebase console

Or you can open the google-services.json file and look for the package name.

Since my package name is com.myapp, I’ll put con.myapp in the textbox. 

Remember to change the Test AdMob App Id with your own AdMob Ad Id in the meta-data element you added in the setup tutorial.

<meta-data android:name="com.google.android.gms.ads.APPLICATION_ID" android:value="ca-app-pub-YOUR_OWN_APP_ID"/>

Select the location of where to store the packaged files. Then wait for it to finish.

Packaging for IOS

To package your project for iOS, make sure you have your GoogleService-Info.plist file in the root directory.

In the Bundle Information section, make sure it is the same as the one in the Firebase console.

Or you can open the GoogleService-Info.plist file and look for the bundle identifier.

Since my bundle id is com.myapp, I’ll put con.myapp in the textbox. 

Remember to change the Test AdMob App Id with your own AdMob Ad Id in the Additional Plist Data you added in the setup tutorial.
