Dec 1, 2025Month: 2025-12 — The year-end milestone delivered a comprehensive PDF Text Highlighting and Annotations feature in androidx/androidx, enabling end-to-end text highlighting with both free-form and snap-to-text modes, robust touch handling, and improved API surfaces for EditablePdfViewerFragment. The work is anchored in a modular highlight system that cleanly separates in-progress highlights from finished annotations, improving maintainability and extensibility for future annotation features. Key features delivered: - PDF Text Highlighting and Annotations feature: new InProgressHighlightsView for rendering wet highlights, support for touch-driven highlight lifecycles (start, update, finish, cancel), and integration with highlighter for both free-form and snap-to-text modes. API improvements for EditablePdfViewerFragment, including internalization of certain exceptions and tightening of styling options. - Core commits and outcomes: - bc3e62c4bba8386c392ddbb3a4594a61668c30aa: Add InProgressHighlightsView and supporting types (InProgressHighlightId, InProgressHighlightsFinishedListener, TextHighlightCallback); tests added (InProgressHighlightViewTest.kt). - 46c3d8dc46840fb078c6c798803dbe02d5a12de9: Add touch handling for in-progress text highlights (WetHighlightsViewTouchHandler, PageInfoProvider to map coordinates), lifecycle management for highlights. - 4d281861f56161e8d6509e79f0ec233559bde646: Relnote for API feedback: internalize ApplyInProgressException and adjust PdfStylingOptions protection level. - 71efcff9eeca0f078dc26e328efbfd07ab41670a: Update AnnotationsView to FrameLayout and wire in InProgressHighlightsView for snap-to-text highlighting; API exposure updated. - fdc3bc8010e73f694a6599521ba5cf881b486942: Integrate highlighter into EditablePdfViewerFragment with a new touch dispatcher routing to ink view or text highlights view; supports both free-form and text-based highlighting. Major bugs fixed: - Stabilized in-progress highlight lifecycle, ensuring start, update, finish, and cancel events reliably propagate to the final annotation creation. - Hardened touch gesture detection and coordinate mapping for multi-page PDFs via PageInfoProvider and WetHighlightsViewTouchHandler. - Tightened API exposure and lifecycle constraints to prevent misuse (ApplyInProgressException and PdfStylingOptions exposure). - Improve stability of snap-to-text highlighting and integration with annotations rendering. Overall impact and accomplishments: - Results: A polished, production-ready PDF annotation workflow with improved UX, reduced friction for users annotating PDFs, and a scalable architecture for future features. - Business value: Higher user engagement and productivity in PDF workflows, enabling teams to annotate, collaborate, and share highlights and notes more efficiently. - Code quality: Clear separation of concerns between in-progress highlights, final annotations, and rendering layers; added tests around critical highlight flows to guard against regressions. Technologies/skills demonstrated: - Android UI architecture: custom views, FrameLayout composition, and touch dispatching. - Gesture handling and coordinate mapping across PDF pages (WetHighlightsViewTouchHandler, PageInfoProvider). - Modular design: InProgressHighlightsView, AnnotationsView integration, and EditablePdfViewerFragment API improvements. - Testing: Unit/UI tests for new highlight components and end-to-end interaction flows. - API design and access control: careful exposure of internal APIs (ApplyInProgressException) and protective adjustments to PdfStylingOptions.

Sep 1, 2025September 2025 (2025-09) - androidx/androidx Key features delivered: - Annotation support and PDF stamp conversion improvements: Migrated stroke transformation to the ink library via strokeToWorldTransform, centralizing stroke handling, improving stroke bounds calculation and conversion to stamp annotations, and removing outdated stroke processing for more accurate, reliable PDF annotations. Added robustness through integration tests for EditablePdfViewerFragment and enforced SDK extension requirements (annotations supported from SDK extension version 18). - PDF viewer fast scroller rendering improvements: Enabled the fast scroller to render on top of overlays, introduced enableDefaultFastScrollerRendering, and adjusted drawing logic to keep the scroller visible with other UI elements. Major bugs fixed: - DiscardChangesDialog stability on rotation: Fixed a crash on device rotation by using a no-arg constructor and Fragment Result API to prevent configuration-change instantiation issues. Overall impact and accomplishments: - Improved annotation accuracy and reliability, reducing user-facing errors and improving PDF workflow. - Stabilized UI behavior during configuration changes, delivering a smoother user experience. - Enhanced rendering performance and UX with the fast scroller overlapping overlays and reduced dead code. - Strengthened test coverage for annotation features and UI components, with tests and SDK extension checks in place. Technologies and skills demonstrated: - Ink library integration and strokeToWorldTransform-based transformation pipeline - Integration testing for UI components (EditablePdfViewerFragment) - Fragment Result API for robust navigation/communication across fragments - Overlay-aware rendering and performance tuning for fast scroller - Code cleanup and rendering tuning (removal of unused PathPdfObject to Stroke conversion, brush epsilon adjustments)
