At v5 it was possible use only Banner without the APPLICATION_ID. But Now If I don't have the AdMob ID, the app will crash (https://developers.google.com/admob/android/quick-start#update_your_androidmanifestxml). For Now I have add the sample ID.

On iOS, just adding (https://developers.google.com/ad-manager/mobile-ads-sdk/android/quick-start) It will work, but on Android I need to have this AdManager ID.
