Oct 2025 highlights: Across OsmAnd family, delivered user-facing features, improved data parsing, and strengthened CI/automation. Key features delivered include: applying getAmenityMetricsFormatted to ClickableWay to standardize metrics presentation and improve data consistency; adding shields/icons for ClickableWay POI/GPX to enhance visual cues; implementing distinct naming for pisteRoutes and ski slopes and enabling showSkiSlopes logic via pisteRoutes to align UI with user expectations; implementing sorting and indexing improvements in TravelObfGpxFileReader and related ClickableWayTags enhancements for nameless objects and GPX shield tag generation; UI declutter improvements by hiding Amenity Metrics Tags in OsmAnd-resources; Weather data download reliability enhancements to boost script stability. Major bugs fixed include: Elevation Metrics Parsing bug (double values after parseElevationMetricsTags); multi-segment approximation fix; NPE hotfix in PointDescriptionMenuController; hotfix IllegalArgumentException in searchTravelGpx; hotfix regression in RenderedObject getOsmObjectId. Overall impact: these changes improve data quality, user experience for ski routing, reliability of weather data workflows, and stability of builds and monitoring; cross-platform route handling improvements also shipped to iOS. Technologies/skills demonstrated: Java/Kotlin refactoring and feature work, regex/data parsing robustness, UI asset integration (shields/icons), shell scripting hardening for weather data, and CI/CD reliability enhancements.
