Now that you've written your app, one way you can monetize it is by enabling it to carry advertising.
Confirm that your ad network's SDK is compatible with Google Play Instant
For an app to be able to carry ads from your ad network, your ad network's SDK must be compatible with Google Play Instant. To confirm compatibilty, follow these steps:
Download the sample instant app from the Google Play Instant samples page.
Integrate your SDK with the sample.
Validate each type of ad you serve, such as banner ads or interstitial ads.
Ensure that your ad network's SDK doesn't serve HTTP ads. Doing so breaks the instant-app experience, because Google Play Instant doesn't allow HTTP traffic.
After you confirm compatibility, contact firstname.lastname@example.org to have your app added to the network. If there are issues with integration, reach out to email@example.com.
Configure your app for ads
To configure your app to carry ads, you must integrate an Google Play Instant-compatible ad-network SDK into your app. The Google Mobile Ads Lite SDK is one such SDK. For more information about integrating an ad-network SDK, see the guides related to Google Mobile Ads Lite SDK and AdMob.
If you plan to integrate a different ad network's SDK into your app, consider reaching out to your relevant ad network to have them integrate with Google Play Instant.
