Privacy Sandbox Developer Preview 9: Custom Audience Delegation

Posted by Jon Markoff, Privacy Sandbox Developer Relations

Earlier this year we released the first Privacy Sandbox Beta on Android, with the goal of bringing real-world testing of our private advertising solutions to users' devices.

Since then, we’ve launched several additional Privacy Sandbox releases, each with new features and improvements, in Developer Preview and Beta. This is part of our ongoing commitment to helping developers create privacy-focused apps and tools that keep content open and accessible to everyone. Your feedback has helped us refine and improve these releases and new design proposals, and is greatly appreciated.

Today, we’re announcing Developer Preview 9 for the Privacy Sandbox on Android, including:

  • Protected Audience API: The first release of Custom Audience Delegation, which supports the creation of custom audiences for buyers that do not have an on-device SDK presence. Bidding and Auction services integrations are available to support more complex ad auctions.
  • Attribution Reporting API: Enrollment is no longer required for development and testing purposes. Improvements to debug reporting include supporting additional verbose debug report and app-to-web debug reports.
  • SDK Runtime: With some limitations, SDK Runtime can now launch intents to other apps, and can bind to an allowlist of services.
  • For the full list of released features, see the release notes.

Alongside Developer Preview 9, we’re also announcing Project Flight: a collection of sample apps that demonstrate how the Privacy Sandbox APIs can be used together in end-to-end user journeys. Project Flight includes the following:

  • Advertiser app, to demonstrate a conversion by booking a travel experience
  • Publisher app, to show a relevant ad and register an event
  • SSP library, to demonstrate running ad selection and registering a source
  • MMP library, to demonstrate joining a custom audience and registering a trigger
  • A mock server backend as a companion to the Protected Audience and Attribution Reporting APIs using Firebase

As with all of our releases, we highly encourage developers to share feedback as they continue their journey into the Privacy Sandbox on Android. To get started, read the instructions to set up the SDK and system images on an emulator or supported Pixel device.

Preparing for the Android Privacy Sandbox Beta

Posted by Anthony Chavez, VP Product ManagementIn February we announced the Privacy Sandbox on Android, with the goal of bringing new, more private advertising solutions to mobile.

Over the course of 2022, we've published design proposals and released a number of Developer Previews. We appreciate all of the feedback we've received which has helped us refine and improve these proposals.

Beginning early next year we plan to rollout the initial Privacy Sandbox Beta to Android 13 mobile devices, so that developers can take the next steps in testing these new solutions. We'll start with a small percentage of devices and increase over time. Note that Developer Previews will continue to be released and this is where we’ll first deliver the latest features for early feedback before being released on production devices.

Today, we're sharing more details about the Privacy Sandbox Beta so that developers can get prepared.


Enroll to access the Privacy-Preserving APIs

Starting with the Beta release, as well as future Developer Previews, developers will need to complete an enrollment process in order to utilize the ads-related APIs (including Topics, FLEDGE, and Attribution Reporting). The enrollment process will verify developer identity and gather developer-specific data needed by the APIs. You can learn more about how to enroll here.


How to participate

The Privacy Sandbox Beta will be available for ad tech and app developers who wish to test the ads-related APIs as part of their solutions.

During the initial rollout stages, enrolled developers will also need to join the early testers program. This program will allow developers to test the APIs on a limited number of their own Android 13 devices for internal apps and requested published apps.

For the SDK Runtime, we’ll have a closed beta for developers to test Runtime-enabled SDK distribution to select apps. Because of the coordination required to test the SDK Runtime on production devices, we expect this beta to involve a limited number of partners who can dedicate resources to support this testing. If you’re interested in participating, please register your interest.

To utilize the Beta release, developers will need to compile their solutions with an API level 33 SDK extension update that is coming soon.


Advice For Advertisers & Publishers

We’ve heard from many advertisers and publishers about the role they can play in testing these new technologies. For companies that rely on third party solutions for ad serving or ad measurement, we recommend working with your providers to understand their testing roadmaps and how you can participate in early testing of Privacy Sandbox.

We want to thank everyone who has engaged on the Android Privacy Sandbox, and look forward to continued feedback as we enter this next phase of testing."

Privacy Sandbox Developer Preview 3: Support for conversion measurement, custom audiences, and ad selection

Posted by Fred Chung, Android Developer Relations

Privacy Sandbox Developer Preview 3 

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.

This release includes a developer guide and sample apps to help you understand client- and server-side set up and interactions for key parts of the attribution reporting workflow, including:

  • 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.)

To help facilitate testing, the release also supports ADB commands to override reporting time windows. Refer to the API reference to learn more about the Android client APIs.


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
  • Fetch JavaScript auction code from remote endpoints
  • Configure and initiate on-device ad auctions
  • Handle impression reporting

To learn more, refer to the Custom Audience and Ad Selection API reference pages, as well as the release notes.


Other key features

If you’re just starting to explore the Developer Preview, please also review the supported features described in the SDK Runtime and Topics API developer guides.

If you need a refresher on key technologies for the Privacy Sandbox on Android, we recommend watching this overview video and reviewing the design proposals.

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.
