# Google Mobile Ads SDK

### Android

Google requires their app-ID to be declared in the manifest. Please follow [these instructions](https://developers.google.com/admob/android/quick-start#import_the_mobile_ads_sdk). In order to get the Google app-ID for you app, either find it within your own AdMob or AdManager account or contact our [support](mailto:support@gravite.net). Follow [Google documentation](https://developers.google.com/admob/android/quick-start#import_the_mobile_ads_sdk) to add your Google app-ID key to the Manifest file.

To add `AndroidManifest` file enable `Custom Gradle Properties Template` in Player Settings -> Settings for Android -> Publishing Settings.

### iOS

Google Mobile Ads SDK requires publishers to add their Google app ID to the Info.plist file of their Xcode projects. Please find your Google app ID within your Google account or contact our [support](mailto:support@addapptr.com). Follow [Google documentation](https://developers.google.com/admob/ios/quick-start#update_your_infoplist) to add your Google App ID to the Info.plist file.

You can define `GADApplicationIdentifier` using [AATKitSettings](/aatkit-unity-integration/other/aatkitsettings-asset.md#markdown-header-gadapplicationidentifier-for-cmp-google-ios).
