Jul 1, 2025July 2025 monthly summary for Simprints/Android-Simprints-ID: Key features delivered: - Unified Synchronization UI/UX across settings, dashboard, and logout with real-time data flow watchers for auth and config changes, plus image sync status and progress reporting. - Down-sync control and module sync checks, coupled with removal of legacy UI components to prevent conflicts and streamline user experience. - Enhanced test scaffolding and supporting data-layer changes to enable the new UI/UX, including a configurable XML layout container and a refreshed module list item view. Major bugs fixed: - Resolved inconsistencies in sync state by introducing the EventSyncManager and EventSyncMasterWorker to support default/cached values and controlled down-sync behavior. - Corrected test naming for EventSyncManager-related changes and completed critical tests (EventSyncMasterWorkerTest, Logout/MainSyncFragmentTest) to prevent regressions. - Cleanup of legacy UI artifacts to avoid UI conflicts and ensure a stable path to the new unified UI/UX. Overall impact and accomplishments: - Substantial improvement to user experience and reliability through a consistent, real-time sync UI and robust data layer foundation, enabling faster iteration on UI/UX and future features. - Improved reliability and observability with explicit progress reporting, real-time watchers, and strengthened test coverage that reduces production risk. Technologies/skills demonstrated: - Android/Kotlin, Kotlin Flow, MVVM, and data-layer architectural patterns (EventSyncManager/MasterWorker). - UI/UX engineering, XML layout tuning, and modular UI updates (module list item view, unified UI container). - Test automation and scaffolding enhancements (ViewModel tests, EventSyncMasterWorkerTest, Logout/MainSyncFragmentTest; test-name corrections).
