Google Mobile Ads SDK v17.0.0 以降で必須だと。

Google Ads Developer Blog: Announcing v17.0.0 of the Android Google Mobile Ads SDK

このことは、


implementation "com.google.firebase:firebase-ads:17.0.0"

も同じ。

以下、AndroidManifest.xml の必須記述。


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

  </application>
</manifest>

Ad Manager や NativeAppInstallAd / NativeContentAd も注意が必要な模様。
