Aug 1, 2025August 2025 HedvigAndroid monthly summary focusing on delivered features, major fixes, and overall impact. The month emphasized delivering business-value features with backend integration, UX improvements, and robust code quality. A significant portion of the work was devoted to feature flag-driven capabilities, dependency modernization, and code cleanup to reduce risk and accelerate future delivery. Key outcomes include a backend-integrated cost retrieval flow for move intents with solid error handling, user experience improvements in the input flow, and a comprehensive Claim History feature rollout enabled by a new feature flag with tests and UI/data wiring. The codebase was modernized for Kotlin and dependencies, and quality gates were tightened through linting and test stability efforts. These initiatives collectively improve transparency, reliability, and time-to-market for new capabilities, while reducing technical debt and risk in production.

Feb 1, 2025February 2025: Achieved key features, reliability, and quality improvements in HedvigInsurance/android. Highlights include: - Chat UI stability and coroutine scope management: fixed scroll resets when navigating back, stopped auto-scrolling on first frame, enabled overriding coroutine scope in MoleculeViewModel, clarified naming, and optimized ExoPlayer initialization. - Project-wide Media3 API adoption: opted into the unstable Media3 API for broader playback capabilities and consistency. - Impersonation feature moved to a library: enhanced reuse and maintainability by extracting impersonation into a shared library. - Deep linking and navigation enhancements: travel certificates history deep link added; production deep link URL corrected by prepending www where needed. - Data sourcing and upload handling improvements: added polling for insurance contracts data source updates and consolidated large file upload handling. - UI/UX and quality improvements: UI tier change dialog date info, improved dialog layout, and broader code quality cleanup including ktlint formatting, lint runs, and removal of unused items and manifests. - Testing and observability: improved testing utilities and logging, introduced rum logger for tests, and fixed test imports; added error information for failed messages and file size warnings for large uploads. - Release and stability: backend file size limit increased to 48MB; various CI/test fixes and version bumps for releases. Business value and impact: These changes reduce friction in user interactions (stable chat, reliable deep links, clearer error messaging), improve media experiences, increase system reliability and maintainability, and streamline release cycles with stronger code quality controls.
