- native_root(): pick app root by presence of gps_live/gps_points files.
app_data_dir() is the root directly on this Tauri; the old .parent().parent()
read the wrong dir, so background (screen-off) points were never imported.
- recoverFromFiles: match file->session by id/date, plus session id stamped
into the native file name (gps_points_<ms>_s<id>.jsonl) for exact binding
(gps_set_session_id -> Kotlin bindSessionIfPending). Proximity dedup +-2.5s,
recalc with noDelete (never runs the destructive glitch/>24h filter that
once wiped real rides), delete already-imported files. Progress bar UI.
- bike kcal is NET (daily balance already books BMR*activityLevel): pedaling =
max(physics power/efficiency, MET-net by speed), coasting (power<=0, the bike
would roll unpowered) = basal only. Elevation via cumulative hysteresis.
recomputeAllStats + "recompute elevation/kcal" menu refresh stored tracks
without touching points.
- live recording: the native file is the DB source of truth; watchPosition
only drives the live marker, so a fix is not stored twice with two timestamps.
- track list pagination, SAF local-file picker, tile regions from router.
- applyBearing: use h, not h - rotOffset. The .rec-screen (map + panel) is
CSS-rotated by rotOffset in landscape and setBearing adds another rotate on
the map pane; subtracting rotOffset cancelled the screen rotation for the
map only, gluing course to the portrait top edge while the panel turned.
Using h lets the map turn with the screen -> course points to physical top.
- Poll: guard the requestAnimationFrame yield with !document.hidden. rAF never
fires while the screen is off, so awaiting it there hung the import loop and
froze point import mid-walk (regression from the progressive-draw change).
- recoverSession: import missing native points by the SET of existing
timestamps instead of ts > maxDbTs. Sparse screen-gated points can have a
late max ts, so the old check imported nothing and left the track full of
gaps; also pass sensorData so bearing/accel/gyro are stored.
- stopRecording: replace the dead _lastNativeCount backfill (the variable
is never assigned → guard is always false → missed points were never
saved) with a full timestamp-based re-import from the native points
file, then recompute stats over the complete set. Fixes losing ~90% of a
track when recording with the screen off — the JS import poll is frozen
by the WebView while the screen is off, so only the native file had all
points.
- Poll: draw each imported point via a lightweight onImportPoint and yield
a frame every ~20 points so the track visibly grows as points transfer
on screen-wake catch-up (restores pre-batch behaviour, kept cheap).
- Native: hard-reject fixes coarser than the Min-accuracy setting (drops
coarse cell ~800m that stuck the track); remove low-accuracy and adaptive
relaxation branches so only accurate fixes are recorded, honest gaps otherwise
- Store bearing_deg per point (gps_points migration + addGpsPoint)
- Default Min-accuracy 20 -> 50m (one-time migration, respects user override)
- Fix: http_request was synchronous with no timeout; an unreachable host
(LAN sync on startup) blocked the whole UI ~30s. Now async + spawn_blocking
+ connect(4s)/global(12s) timeouts, fails in background without freezing
- Bundled prior work: course-up map orientation, compass calibration,
online elevation refine (open-elevation), distance gap-gate fix
Regression from per-session points file change (1feb2ef): the service
returns START_STICKY, so when the OS kills it during screen-off, it
restarts with a null intent and onStartCommand minted a NEW points file,
repointing gps_live_points.jsonl and orphaning accumulated background
points. Evidence: many tiny orphaned gps_points_*.jsonl fragments.
Fix: onStartCommand creates a new session file only on a genuine start
from JS (intent with extras). A START_STICKY restart (null intent) keeps
writing to the existing session file from the pointer — one file per
session until Stop.
Verified on device: am kill (= START_STICKY restart) no longer creates
a new file, pointer unchanged, trail resumes on return. Background
writing confirmed: 49 points in 70s with screen off (Dozing) at 1Hz.
Compass:
- Gimbal lock compensation: when phone tilts past horizontal (|beta|>90
in landscape, |gamma|>90 in portrait), heading flips 180 — compensated
- EMA smoothing for heading (factor 0.3, ~300ms settle) — reduces jitter
from road bumps while keeping responsive turns
- 3 orient modes: X(off) A(auto) L(lock) — lock freezes layout, compass
still works with gimbal compensation
- Debug overlay on map shows alpha/beta/gamma/heading/mode
Build:
- ./build.sh install — install last APK without building
- ./build.sh -d install — install debug APK
- install_apk respects -d flag for debug/release selection
Products:
- health-diet.ru scraper (Tampermonkey) + import script
- 11469 products with 37 nutrients, Dodo 258, McDonalds 619, KFC 361, Ashan 2000
- Rust import_seed_products: dynamic column list, auto-create missing columns
- Seed version bumped to 10
GPS session safety:
- Separate gps_points_{ts}.jsonl per session, deleted only after DB save
- Toast on DB errors, NaN guard in finishGpsSession
Other:
- build.sh: router/VPS upload only with -u flag
- Orientation buttons bottom-right, weather via Yandex Pogoda
Settings:
- Aero drag (CdA), air density, pedal efficiency now in GPS config
- Human-readable names: "Аэросопротивление", "Плотность воздуха", "КПД педалирования"
- Saved to localStorage, used in computeStats
Bug fixes:
- Recipe detail: overlay.remove without popHandler cleanup → now uses history.back()
- weightKg parseFloat in startRecording and importGPX (string "88" bug)
- profile.weight_kg stored as number not string
- getDailyActivityTotals: separate params for UNION ALL subqueries
