Dec 1, 2025December 2025 highlights for ankidroid/Anki-Android focused on user-facing reminders, streamlined permission handling, and reliability improvements across onboarding and sync paths. Key features delivered: - Reminders system enhancements: UI consolidation for Add/Edit Reminder, introduced advanced Review Reminders with a setting to only notify if the deck hasn’t been reviewed today; backend check implemented via revlog/cards tables; added unit tests; minor UI refactor from TextView to FixedTextView. - Notification permission flow enhancements and cleanup: request notification permissions on login; centralized permission checks in the Permissions module; removed legacy permission logic; validated across login, deck picker, and settings scenarios. Major bugs fixed: - Metered network warning spinner: fixed indefinite progress spinner by triggering a UI refresh immediately after showing the warning and addressing a race condition with deck reloads (replay = 1 on flowOfDecksReloaded). Overall impact and accomplishments: - Improved user engagement and reliability: reminders are more actionable and less noisy, onboarding and permissions are less friction-prone, and the app recovers gracefully on metered networks. - Strengthened code quality and test coverage: logging refactors, added Permissions tests, and reliability improvements reduce maintenance costs and enable faster iteration. Technologies/skills demonstrated: - Android/Kotlin development, MVVM patterns, Room database interactions (revlog/cards), UI/UX refinements, permission handling, Kotlin coroutines/flows, and test-driven quality improvements.

Apr 1, 2025April 2025: Delivered a UI/UX enhancement in ankidroid/Anki-Android by adding a textual '(empty)' indicator for empty card fronts in the AnkiDroid Previewer. The indicator replaces the previous red badge and is appended to the tab title, implemented via a new string resource and integrated into the TemplatePreviewerPage. This improves clarity for users with empty fronts and supports localization across the app. No major bugs fixed in this repo this month. Impact includes: reduced user confusion, stronger alignment with design guidelines, and improved previewer usability. Skills demonstrated include Android UI development, string resource management, and end-to-end feature delivery.
