Jun 1, 2025June 2025 — BCSDLab/KOIN_ANDROID: Deliveries focused on testing reliability, maintainability, and system stability. Implemented Paparazzi snapshot testing integration for the Android library with Timetable UI tests across devices (including foldables), standardized test naming and structure, and added a custom test device. Launched a server maintenance/inspection UI, including an InspectionActivity and manifest updates to gracefully handle maintenance mode. Tightened build and code quality: build configuration improvements (ignoring Jetifier for common module; add club feature dependency) and ktlint-based code formatting cleanup across the store module. Resolved key reliability issue by simplifying 503 handling in InspectionInterceptor. These changes collectively improve testing coverage, user-facing stability during maintenance, and overall code health, enabling faster iteration and lower risk in deployments.

May 1, 2025May 2025 performance summary for BCSDLab/KOIN_ANDROID. Delivered a modular Store experience with a Core Store Module and Collapsing Toolbar navigation, enabling scalable store detail flows and reusability across screens. Implemented Store Detail Screen and UI components (MenuListSection, MenuCategoryChips, StoreDetailInfoChip, StoreDetailInfoCard, StoreDetailInfo) and associated resource assets (images and strings) to support a polished store detail UI. Implemented robust image loading with graceful handling for empty imageUrls, and migrated theming to resource-based colors for consistent UI theming. Completed a comprehensive Shopping Cart UI (ShoppingCartScreen, ShoppingCartContent, CartMenuItem, QuantityOptionButton, PaymentSummaryCard) to support end-to-end purchase flows. Fixed critical stability issues including window insets handling, parameter handling in ShoppingCartScreen, and visibility scope adjustments. Adopted UI Design System across the product, standardized padding, and integrated testing scaffolding (JUnit-ktx, UI test support, Paparazzi) to improve test coverage. Introduced code quality improvements (ktlint enforcement, immutable collections usage, code maintenance/refactor) and CI/Jetifier configuration cleanup to improve build stability and developer experience. Outcomes: faster feature delivery, consistent theming, improved stability, and better test coverage with a scalable module architecture.
