Flutter for Beginners

AndroidManifest – meta tags

Another very important step is to review the meta tags added to the app for working with services such as AdMob or Google Maps. In our Favors app, AdMob was the only key added, so we can review the value to make sure the service will work with the correct key as well:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.handson">    ...     <application>        ...                <meta-data            android:name="com.google.android.gms.ads.APPLICATION_ID"            android:value="ADMOB-KEY"/>    </application></manifest>

Remember, in AdMob, we can use test keys during development so that our tests are not evaluated as misuse of the API.
