Google's release of Android XR SDK Developer Preview 3 bolsters AI Glasses support, integrating motion tracking and geospatial capabilities for enhanced app functionality.
Enhancements and Libraries
The new SDK introduces two libraries: Jetpack Projected enables projecting XR experiences to AI Glasses, while Jetpack Compose Glimmer offers UI components for augmented reality. The libraries support integrating the glasses' built-in speakers, camera, and microphone, alongside the display if available.
- Jetpack Projected: Projects XR apps using audio/video; checks for display availability.
- Jetpack Compose Glimmer: Provides customizable UI components with optical see-through for AI Glasses.
- Permission requirements: At run-time for hardware access; audio as Bluetooth device.
Developer Tools and Capabilities
Google's Android XR SDK Developer Preview 3 expands ARCore for Jetpack XR, allowing apps to leverage planar data and anchor content spatially. Motion tracking and geospatial positioning enhance content location anchoring using Google Street View data.
- AI Glasses emulator: Simulates interactions like touchpad and voice input in Android Studio.
- ARCore extensions: Offer new features for app-enhanced reality interfacing, including motion and geospatial tracking.
- Availability: Embedded in Android Studio Canary; requires emulator version 36.4.3 Canary or later.
These updates aim to expand developer capabilities and improve user experiences on AI Glasses.
