Fix GPX file opening, share sheet visibility, and add SAF track storage

2026-05-20T08:38:33+00:00

Intent filter fixes: - Remove pathSuffix=".gpx" + scheme restriction from the application/octet-stream ACTION_VIEW filter; pathSuffix matches the URI path, not the filename, so it never fired against file manager content URIs (opaque paths like /provider/uuid). The existing display-name check in handleIncomingGpx() is the correct gate. - Add ACTION_SEND filter for application/octet-stream; Nav was invisible in share sheets because most file managers send this type for .gpx files. SAF-based track storage (API 29+): - Replace fragile SharedPrefs URI cache + OWNER_PACKAGE_NAME MediaStore query with Storage Access Framework as the primary write/read path. The user grants access to their tracks folder once via ACTION_OPEN_DOCUMENT_TREE; DocumentFile.listFiles() finds all GPX files without relying on MediaStore ownership (which Android clears on uninstall). After reinstall, a one-tap "Restore track access" button in Saved Tracks re-authorizes the same folder and all tracks immediately reappear. - MediaStore path (existing) is kept as fallback for tracks saved before this change - Add SafState enum (CONFIGURED / PERMISSION_LOST / NOT_CONFIGURED) in TrackStorage - TrackRepository exposes safState() and initSafDirectory() thin wrappers - MainViewModel exposes safState StateFlow and onSafDirectorySelected() - SavedTracksFragment observes safState and shows contextual setup / re-auth button - MainActivity registers safPickerLauncher and exposes launchSafPicker() - Add androidx.documentfile:documentfile:1.0.1 dependency https://claude.ai/code/session_01YUbuZNDAoLea4cf9UGQ9qn

- TackDetector: sliding-window COG algorithm (60-140deg delta = tack/jibe) with stability check to prevent mixed-window false positives; 13 tests green - TackEvent, SavedTrack: new models wrapping points + summary + detected tacks - TrackRepository.getSavedTracks(): returns List with lazy load - MapHandler: zoomToTrackBounds (LatLngBounds fit with padding), panToPoint (log step-through), updateTackLayer (yellow circle markers) - MainViewModel: savedTracks + selectedTrack StateFlows, panToPosition SharedFlow - SavedTracksFragment: RecyclerView list with date/distance/duration/tack count - TrackDetailSheet: bottom sheet with stats + event log (tacks, speed changes, start/end); tapping an entry pans the map to that position - MainActivity: zoom map on track complete, wire Saved Tracks button in instrument sheet, observe panToPosition to drive map, show tack markers when a saved track is selected Co-Authored-By: Claude Sonnet 4.6
