[SDK Runtime Recap - May] Reported UI obstructions, and new learning resources!

Hi Android Developers,

Welcome back to the SDK Runtime Recap! 

After a brief pause in April, we're excited to share the latest highlights from May, including new ways to detect obstructions in remote UI, version compatibility updates, and new learning resources (with a dedicated code sample repository!)

New features and Jetpack releases

• UI Library (androidx.privacysandbox.ui) - v.1.0.0 - alpha16 release notes

• You can now measure UI obstructions on SandboxedSdkView. These are reported via SessionObserver.onUiContainerChanged() when you include SandboxedUiAdapterSignalOptions.OBSTRUCTIONS in your signalOptions.

• For Compose users, SandboxedSdkUi has been moved from ui-client to a new ui-client-compose library. Remember to update your dependencies to continue using this Composable.

• A bug fix now ensures SandboxedSdkView.setAlpha() correctly updates the content view's alpha.

• Backward compatibility (androidx.privacysandbox.sdkruntime) - v.1.0.0 - alpha17 release notes

• SandboxedSdkProviderCompat.getView()will no longer be supported from the next release onwards. Please consider using the UI library as an alternative.

• Make sure to upgrade any dependencies to these backcompat libraries to alpha14 or higher, as alpha13 is no longer supported.

Learning materials

• [Code samples] New dedicated repository

  • We've launched a new standalone GitHub repository for SDK Runtime code samples: privacysandbox/sdk-runtime-samples.

  • The repository includes an updated README to help you get started with building and consuming privacy-preserving SDKs. Stay tuned, we'll be adding more granular samples soon!

• [Learning pathway] Test your SDK Runtime knowledge

  • Explore the fundamentals of the SDK Runtime with our new learning pathway.

  • Test your understanding with the accompanying quiz!

• [Event] SDK Runtime at I/O 2025

  • The SDK Runtime was featured in the "What's new in Android" session at I/O 2025, highlighting its ongoing importance in the Android ecosystem.
