Lecture Notes on Integrating UMP SDK into Unity Apps

Summary

In this tutorial, Justin Mandulo from Google AdMob's development team demonstrates how to integrate the User Messaging Platform (UMP) SDK into a Unity application. The UMP SDK helps app developers to comply with privacy laws by allowing users to consent to how their data is used. The process includes several key steps such as requesting consent information, loading and presenting a privacy message, initializing the Google Mobile Ads SDK, testing the integration, implementing a privacy options button, and optimizing the integration.

Key Steps for UMP SDK Integration

1. Request for Consent Information

  • Perform this on every app launch.
  • Initiate by creating a blank ConsentRequestParameters object.
  • Update the consent information using ConsentInformation.update() with a callback.
  • Handle any errors through the passed callback.

2. Load and Present a Consent Form

  • Execute inside the callback from the consent information update.
  • Use ConsentForm.load() and show() if consent is needed; if not, the callback is quickly invoked.
  • Setup the consent form to be dismissed by the user, handling any required or not required scenarios.

3. Initialize the Google Mobile Ads SDK

  • Initialize after the consent gathering process.
  • Use a helper variable canRequestAds from the GoogleMobileAdsController class to check if ads can be presented.

4. Test Integration

  • Implement test scenarios to ensure correct behavior in different geographies like GDPR affected areas.
  • Use consent debug settings to simulate different user locations (e.g., Europe).
  • Build and run the app using an iOS platform for this test.

5. Implement a Privacy Options Button

  • This button allows users to modify their consent at any time within the app.
  • Check the privacyOptionsRequirementStatus to determine if the button should be active.
  • When activated, use ConsentForm.showPrivacyOptionsForm() to present the options to the user.

6. Optimize the Integration

  • For returning users, optimize the consent process to avoid delaying ad impressions.
  • Attempt to initialize the SDK outside of the consent information update callback if previous consent is already stored.
  • Ensure the SDK is only initialized once during the consent gathering process to maximize efficiency.

Important Code Snippets and Concepts

  • Consent Debug Settings: Configure settings to test app behavior under regulatory conditions.
  • Handling Form Dismissal: Always ensure that consent forms can be properly closed or dismissed by the user.
  • Boolean Flags: Use these to control when the SDK initializes to avoid multiple initializations.

Key Classes and Files

  • GoogleMobileAdsConsentController: Manages consent information gathering and updates.
  • GoogleMobileAdsController: Handles the Google Mobile Ads SDK initialization based on the consent status.

Conclusion

The integration of the UMP SDK into a Unity app involves careful handling of user consent, initialization of advertising services post-consent, and optimizing the flow to enhance user experience and comply with privacy laws.

Note: Remember the importance of testing the integration thoroughly, specifically in environments with strict privacy regulations like Europe, to ensure all consent mechanisms are functioning correctly.
