The Privacy Sandbox on Android aims to develop new solutions that preserve user privacy and enable effective, personalized advertising experiences for apps. Since our first developer preview, we've shared progress updates and continue to engage the industry on everything from the Developer Preview timeline, to Topics taxonomy, to SDK version management. We appreciate your feedback!
Today, we’re releasing Developer Preview 3, which includes APIs and developer resources for conversion measurement and remarketing use cases. In addition to the preview of SDK Runtime and Topics APIs released earlier, you can for the first time begin testing and evaluating impact on all key APIs for Privacy Sandbox on Android.
Event-Level and Aggregate Attribution Reporting APIs
These APIs allow developers to measure when an ad click or view event leads to a conversion, such as the download of a new game. They support key use cases for attribution across apps and the web, and improve user privacy by removing reliance on cross-party user identifiers.
- Registering attribution source and trigger events.
- Receiving event reports and unencrypted aggregatable reports.
(Note that aggregatable report encryption is not yet implemented. See the release notes for details.)
Custom Audience and Ad Selection APIs
Part of FLEDGE for Android, these APIs provide the building blocks to serve customized ads to users based on previous app engagement, without third-party data sharing. You’ll be able to:
- Manage Custom Audience membership and observe how its parameter values may affect auction outcomes
- Configure and initiate on-device ad auctions
- Handle impression reporting
Other key features
Get started with the Developer Preview
Today’s Developer Preview release provides the resources you need to begin early testing of features and share feedback. To get started developing, see instructions to set up the SDK and system images on the emulator or supported Pixel devices.
