Jetpack XR SDK core libraries reach beta: The next milestone for Android XR

Posted by Amy Zeppenfeld, Developer Relations Engineer, Greg Underwood, Software Engineering Manager, Yasmine Evjen, Senior Product Manager, Android XR

Since introducing the Android XR SDK, developers have transformed their ideas into innovative, immersive experiences for XR headsets and wired XR glasses. As the ecosystem expands, you can more easily take those experiences from preview to production and reach users wherever they are.

Today, we're excited to announce that Jetpack SceneCore, ARCore for Jetpack XR, and XR Runtime have reached beta with Jetpack Compose for XR to follow soon! This means the APIs are stabilizing, making it a great time to start integrating them into your production workflows and creating for Android XR.

Why the Jetpack XR SDK?

The Jetpack XR SDK includes all the tools and libraries you need to build immersive and augmented experiences for Android XR. Whether you're porting an existing 2D app or creating a new 3D XR app from scratch, you can do so using the familiar Android development tools you already know and love.

To support your development, this release focuses on providing the fundamental building blocks across the SDK:

• Jetpack SceneCore: Build and manipulate the Android XR scene graph with 3D content. You can arrange 3D models, play spatial audio, and use the robust entity-component system to create, control, and manage entities.
• ARCore for Jetpack XR: Bring digital content into the real world with perception capabilities. This library powers depth estimation, persistent anchors, hit testing, and plane identification.
• XR Runtime: Provides the essential runtime foundation of the SDK, handling device lifecycles, session creation, and system configurations that enable the API surface.
• Jetpack Compose for XR: Create spatial UI layouts that take advantage of Android XR’s spatial capabilities. This library lets you use familiar Compose concepts to create spatial UIs and will be reaching Beta soon.

What's new in Beta?

Direct feedback from the developer previews helped shape these beta releases, introducing several important API refinements to ensure these libraries are ready for production.

• Expanded testing support: New capabilities are now available across the immersive XR libraries, including testing for spatial audio, XR devices, and session configuration. See the release notes for each library for details.
• Kotlin coroutines support: To better align with Kotlin coroutines, Session.create is now a suspend function.
• Terminology and class updates: AnchorEntity has been renamed to AnchorSpace, and both ActivitySpace and AnchorSpace now extend a common SpaceEntity class for more consistent spatial management across scenes.

See the full release notes for each library to check out specific details on naming and API changes.
