Mar 1, 2026March 2026 monthly summary for androidx/androidx focused on delivering the PerceptionState Snapshot and Immutability Enhancement. Introduced a snapshot mechanism to track the states of objects within PerceptionState, enabling a self-referencing state and stronger immutability, while unrestricting eye states. Change validated with unit tests and on-device verification (Moohan device and Pixel 8), addressing state-transition stability gaps across devices. This work reduces risk of state corruption, improves debuggability, and provides a robust foundation for future perception features. Commit overview: d8c65b6131b49dcbea14d9187e9cbafcb2e65982 — PerceptionState now holds a snapshot of object states and includes a self-reference; unrestricts eye states. Tests on Moohan and Pixel 8. Related bugs: 464075476, 442760994. Change-Id: Ic65931f90f15acc1c50a0f10d9377224f75b53d0

Aug 1, 20252025-08 Monthly Summary for androidx/androidx: Delivered DepthMap API enhancements and mobile ARCore support, enabling left/right/monocular depth maps via a new DepthMap runtime and expanded public APIs to support richer AR experiences on mobile. Unrestricted Depth Map APIs were introduced to broaden adoption and simplify integration across devices. Release stability was hardened by addressing runtime linking issues in the production build (UnsatisfiedLinkError) through updated Proguard rules, improving device compatibility such as on Pixel 8. These efforts drive tangible business value by enabling advanced AR features, improving user experience, and increasing release confidence. Notable commits include fdd3c99ac112f682710277329a8a549646956f3b (DepthMap Mobile Runtime), aca2a19f63f4a62da013bec13ac7e6ba5a7636c0 (Depth Map Implementation Update), 168167fedb76e163e9e64ae7774842182431bba1 (Unrestrict Depth Map APIs), and b47dc11af45f6e39610c17bfed9daf9b65ead3d1 (ARCore Mobile Whitebox Release App Fix).
