PROFILE
Ben King
Kinben developed advanced geospatial and augmented reality features for the androidx/androidx repository, focusing on ARCore and OpenXR integration. Over five months, Kinben delivered APIs for geospatial localization, surface anchoring, and VPS availability, using Kotlin, Java, and JNI to bridge native and managed code. The work included refactoring for resource management, UI enhancements for anchor selection, and encapsulation improvements to streamline API surfaces. Kinben’s approach emphasized robust testing, code hygiene, and alignment with governance standards, enabling reliable AR experiences across diverse environments. The depth of implementation established a solid foundation for future geospatial and AR capabilities within AndroidX.

Dec 1, 2025December 2025: Delivered geospatial AR capabilities in OpenXR via AndroidX with JNI exposure to Kotlin and a Jetpack library integration. Introduced a Geospatial Activity UI for anchor management and permissions, and added Jetpack support for CreatePoseFromGeospatialPose with API authentication handling. Updated the OpenXR Sample to demonstrate geospatial features, with basic functionality verified (info panel, anchor creation/restoration) and device-specific behavior documented for unsupported devices. Addressed stability issues including a crash caused by converting spatial entities to XrSpace during anchor destruction; captured improvements for known issues (CheckVpsAvailability not yet supported).

Oct 1, 2025Month 2025-10: Delivered the initial Jetpack Geospatial API surface for androidx/androidx with API naming alignment (Earth renamed to Geospatial) and public exposure of core capabilities. Implemented API consistency improvements, including removing the session parameter from checkVpsAvailability to align with other geospatial methods, and exposed Geospatial.State and pose conversion APIs (createPoseFromGeospatialPose, createGeospatialPoseFromPose). Completed targeted bug fixes and tests tied to the Geospatial changes. The work lays groundwork for VPS availability workflows and future OpenXR runtime integration, enabling developers to adopt geospatial capabilities more quickly and reliably.

Jul 1, 2025July 2025: Key feature delivered—ARCore VPS Availability API (checkVpsAvailability) for geospatial localization in androidx/androidx. Implemented two commits: (1) Add API for checkVpsAvailability; (2) Restrict visibility of checkVpsAvailability APIs to internal library groups, removing from the public API surface. Business value: enables geolocation-based VPS checks for AR experiences while tightening API boundaries to reduce maintenance risk. No major bugs fixed this month; focus was on feature delivery and code hygiene. Overall impact: strengthens ARCore integration with geospatial localization workflows and establishes a cleaner foundation for future features. Technologies/skills demonstrated: ARCore integration, geospatial localization, API design and access control, encapsulation, commit-driven development.

Jun 1, 2025June 2025: Delivered Geospatial VPS Availability API for Jetpack XR and improved ARCore camera test stability. The Geospatial Check VPS Availability API enables developers to verify VPS availability for specific coordinates via ArCorePerceptionManager, with tests added to cover VPS scenarios. Fixed resource management leak in ARCore camera tests by refactoring to use a HardwareBuffer 'use' block, improving test stability and reliability for camera-related features. These changes enhance geospatial capability exposure and provide a more robust testing baseline, reducing risk for downstream apps relying on AR features. Tech excellence included API design in Jetpack XR, ARCore integration, Kotlin/Java resource management patterns, and test refactoring.
