April 2026 (androidx/androidx): Key feature delivered focusing on API stability and developer experience. The WavyProgressIndicator APIs in Material3 were stabilized by removing experimental annotations, locking down the API surface for production use, and aligning usage with Material3 visuals. Updated API docs and sample usages to reflect the production-ready API and enhance developer experience. Major bugs fixed include addressing Bug 497877853 related to WavyProgressIndicator changes and ensuring a smooth upgrade path. Validation was performed with the API update routine and release notes were prepared to promote the new API surface. Impact: This work reduces upgrade churn for downstream apps, improves consistency across Material3 components, and provides a stable foundation for future improvements in the WavyProgressIndicator visuals and behavior. Technologies/skills demonstrated: AndroidX, Material3, API stabilization, Gradle-based tooling, API documentation and samples, test automation (updateApi), release notes and changelog traceability.

Month: 2026-03 — Focused on developer documentation in androidx/androidx. Key feature delivered: refined KDoc for MinimumInteractiveTopAlignmentLine and MinimumInteractiveLeftAlignmentLine to clearly indicate that alignment lines reflect the component's original visual bounds prior to the extra space added by Modifier.minimumInteractiveComponentSize. This clarifies usage and reduces misalignment errors when aligning other UI elements. This work addresses API Council feedback (b/487986819) and preserves existing API names for backward compatibility. Commit: f3bd336c5273d85f48c41aab8ac9d4de02315d0e; Change-Id: I7902d64b2e629b42b2e6a5d8fe177e2829a0ce91.
