PHP api/index.php:
- DB connection failure (500) now calls _phpErrorReport()
- Main router catch-all (500) now calls _phpErrorReport()
- undoTransaction DB error (500) now calls _phpErrorReport()
PHP api/cron_smart_shopping.php:
- cron Throwable catch now calls _phpErrorReport() before exit(1)
(fires even in CRON_MODE since _phpErrorReport() has its own guard)
Scale Gateway GatewayWebSocketServer.kt:
- onError() now calls ErrorReporter.report(ex, ...) in addition to Log.e
Combined with previous kiosk commit, every error path in the entire
EverShelf stack now sends an automatic GitHub Issue.
Root cause of 'stuck on downloading' bug (Android 13+):
DownloadManager.ACTION_DOWNLOAD_COMPLETE is sent by the system process,
which is external to our app. Registering the receiver with
RECEIVER_NOT_EXPORTED silently drops the broadcast — the BroadcastReceiver
never fires, the install never starts, and the UI stays frozen at
whatever progress percentage the poller last saw.
Fix: use RECEIVER_EXPORTED for the DownloadManager completion receiver in
both kiosk and scale-gateway apps.
The PackageInstaller result receiver (internal PendingIntent broadcast,
same package) correctly keeps RECEIVER_NOT_EXPORTED — that one is
intentionally app-private.
Webapp update banner:
- 'Vedi novità' link replaced with 'Aggiorna ora' button
- Clicking 'Aggiorna ora' does a hard page reload (?bust=timestamp)
which forces the browser to fetch the latest files from the server
- GitHub release URL kept as a small secondary 'novità' link
APK install conflict (kiosk + scale gateway):
- STATUS_PENDING_USER_ACTION: changed startActivity → startActivityForResult
(kiosk) / installConfirmLauncher.launch (gateway) so we get notified
if the system installer fails due to signature conflict
- On non-OK result from system installer: show AlertDialog offering to
uninstall, using UNINSTALL_REQUEST / uninstallLauncher
- STATUS_FAILURE_CONFLICT/INCOMPATIBLE: same uninstall flow
- After uninstall completes, install automatically retries with the
saved APK file (pendingInstallFile) — no manual re-download needed
- Gateway: also saves destFile to pendingInstallFile at download time
APK install conflict:
- Replace ACTION_VIEW-based install with PackageInstaller.Session API (API 21+)
- PackageInstaller gives us the actual install status via BroadcastReceiver:
STATUS_PENDING_USER_ACTION → launch system confirmation dialog automatically
STATUS_SUCCESS → success toast
STATUS_FAILURE_CONFLICT/INCOMPATIBLE → show AlertDialog offering to
uninstall the old version (ACTION_DELETE) so user can re-download and install
- FileProvider no longer needed for install (still kept for other uses)
- Kiosk: derive target package from filename (gateway vs kiosk self-update)
Dashboard 0-flash:
- Replace hardcoded 0 in HTML stat-value spans with ... placeholder
- Add .stat-loading CSS class: shimmer skeleton animation (gradient sweep)
- showPage(dashboard): set ... + stat-loading before API call
- loadDashboard: remove stat-loading class and set real count after data arrives
- Add full-screen CSS preloader to webapp (fades out when _initApp completes)
- Defer _checkWebappUpdate() to 6s after app init so it does not compete
with startup API calls (fixes perceived slowness on first load)
- Switch update-check throttle from sessionStorage to localStorage (6h TTL);
use release published_at instead of version string for comparison, so the
banner correctly appears when a new release is published regardless of whether
the tag is a semver or the rolling "latest" tag
- PHP _isLatestVersion(): return true (do not suppress error reports) when
tag_name is non-semver (e.g. "latest") — was incorrectly blocking ALL reports
- Kiosk checkForUpdates(): show banner only when the release asset actually
contains an APK for the component; handle non-semver tag by treating it
as always-update (prevents silent no-op with rolling "latest" tag)
- Scale gateway checkForUpdates(): same non-semver fix; apkUrl now defaults
to empty and bails out if no matching APK found in assets (prevents 404 install)
Root causes fixed:
- REQUEST_INSTALL_PACKAGES permission missing from both manifests
- FileProvider not declared in either manifest (FileProvider.getUriForFile() crashed)
- res/xml/file_paths.xml missing (required by FileProvider)
- setDestinationInExternalPublicDir() used public Downloads dir (needs storage
permission + FileProvider can't serve it); replaced with getExternalFilesDir()
which is app-private, needs no permission, and IS accessible by FileProvider
- canRequestPackageInstalls() check returned early with startActivity (fire-and-
forget); user could never retry. Now uses startActivityForResult/installPermLauncher
so the download auto-retries when user returns from the Settings screen
- Added download status check (COLUMN_STATUS == STATUS_SUCCESSFUL) before installing
in both PHP (api/index.php) and Scale Gateway (ErrorReporter.kt)
- Add _isLatestVersion() / _latestReleaseTag() / _appVersion() helpers in PHP;
skip GitHub issue creation if caller is not on the latest released version
- Add checkUpdate() PHP endpoint (GET api/?action=check_update, no auth required)
- Webapp (app.js): fetch check_update on load, show dismissible amber top-banner
when a newer GitHub release is available; auto-dismiss after 20 s
- Kiosk (KioskActivity.kt + activity_kiosk.xml): replace old JS bottom-banner with
native Android top-banner; real APK download via DownloadManager + PackageInstaller
- Scale Gateway (MainActivity.kt + activity_main.xml): same native top-banner
with checkForUpdates() / showNativeUpdateBanner() / triggerApkDownload() / installApk()
- PHP (api/index.php): hardcode GH_ISSUE_TOKEN/GH_REPO constants at top of
file (before exception handler runs); fix $fp_ variable interpolation bug;
global set_exception_handler + register_shutdown_function; reportError()
endpoint (POST ?action=report_error) with rate limiting, local log, dedup
via fingerprint search on GitHub Issues API
- Kiosk (ErrorReporter.kt): add crash persistence – saves crash payload to
SharedPreferences before network POST, clears on success, retries as
'uncaught-exception-survived' on next launch via sendPendingCrash() in init()
- Scale Gateway: new ErrorReporter.kt – calls GitHub Issues API directly
(no relay needed, token hardcoded, scoped Issues R+W only); crash
persistence via SharedPreferences; MainActivity.kt hooked at onCreate,
startGatewayServer catch, onError (BLE errors)
Tested end-to-end: issues #3-#6 created and closed during QA.
- Fix progress-bar restarting continuously when weight is stable:
add _cancelScaleTimersOnly() that stops timers/animations without
_cancelScaleTimersOnly() so the same value resumes counting when
stability returns instead of always restarting the 5-s wait.
Add 'else if' branch in _scaleAutoFillUse / _scaleAutoFillRecipeUse
to restart stability wait after brief instability for the same value.
- Show red blinking warning in scale-live-box when weight < 10 g:
adds scale-low-weight CSS class with pulsing border/shadow animation,
the label shows '< 10 g · inserisci manualmente' instead of the
stability progress bar. No auto-confirm fires below 10 g.
- Gateway Android app: scale auto-reconnect now retries indefinitely.
isAutoReconnecting flag keeps the scan→wait→scan cycle running until
the scale is found again; onScanStopped schedules a new scan after
10 s whenever autoReconnect is active and scale is still offline.
When the scale turns off by itself (auto-off after inactivity), onDisconnected()
now automatically restarts BLE scan after 5 s, with enableAutoConnect() set so
the saved scale is connected as soon as it starts advertising again.
The hint text shows '🔄 Reconnecting to saved scale in 5 s…' during the wait.
- ScaleProtocol: WeightReading now holds Float value + String unit
- parseQNFood: divide raw by 10 (0.1-unit resolution) so 170 raw -> 17.0g
- parseQNFood: detect unit from byte[4] (0x01=g, 0x02=oz, 0x03-04=ml)
- GatewayWebSocketServer: publishWeight(value: Float, unit: String, ...)
WebSocket now sends {"value":17.0,"unit":"g"} with correct precision
- BleScaleManager: reading.grams -> reading.value (Float check > 0f)
- All Italian UI strings translated to English in all 4 Kotlin files + XML
The QN-KS sends 18-byte frames on FFF1 with opcode 0x10:
[0x10][0x12=len][...][flags][weight_hi][weight_lo][...][crc]
Weight is u16BE at bytes 9-10 in grams (1g resolution).
Stable flag is bit 3 of byte[8] (0xF8=stable, 0xF0=settling).
Checksum = sum(bytes[0..16]) mod 256.
The generic parser was reading byte[1]=0x12=18 as '18 grams' (the
packet length field), which is why it always showed 18g.
Added parseQNFood() with CRC validation, detected before generic fallback.
Also added AE00/AE02 UUIDs (secondary notifiable service on QN-KS).
- Version label (e.g. v2.0.0 (6)) displayed in the app header
- Copy and Share buttons appear when debug panel is open
- Copy puts full log in clipboard, Share opens Android share sheet
- Generic parser now supports food scale weight ranges (1g-15kg)
with candidates for gram, 0.1g, and 0.5g divisors
- WebSocket sends grams (unit: 'g') for weights under 15kg
- MainActivity displays grams for food-scale readings
- Enhanced debug: raw byte dump on decode failure with index/decimal/hex
- versionCode=5, versionName=1.6.0
- Remove Unicode ─ characters from section comment dividers that caused
Kotlin compiler parse error (line 191:83 Closing bracket expected)
- Use plain ASCII dashes in section comments
- Remove inline field comments from data class
- File was duplicated (672 lines), truncated to correct 316 lines
BREAKING FIX: 'always 1.8 kg' — the old brute-force parseGeneric was
matching noise bytes. Replaced with protocol-specific parsers:
Protocol support (from openScale research):
- Bluetooth SIG 0x2A9D/0x2A9C (standard weight/body composition)
- QN/Yolanda/FITINDEX (opcode 0x10 weight, 0x12 scale info)
- 1byone/Eufy (0xCF header, LE weight at bytes 3-4)
- Hesley/YunChen (20-byte body composition frame)
- Renpho proprietary (0x2E header on 0x2A9D)
- Safe generic fallback (stricter: min 4 bytes, min 2kg, unstable)
Body composition fields: fat%, muscle%, water%, bone, BMR/kcal,
impedance — all displayed when available.
Debug panel fix: capped at 150 lines, UI updates throttled to 200ms
(was: unbounded StringBuilder updated on every BLE notification = freeze).
Auto-reconnect: saves last connected device MAC to SharedPreferences,
auto-starts scan on app launch and connects when saved device found.
GATT service discovery: now explicitly subscribes to QN (FFE0/FFE1)
and custom FFF0 (FFF4 or FFF1) characteristics in addition to
standard Weight Scale and Body Composition services.
ScaleProtocol state: resetState() called on new connection to reset
QN weight divisor (100 or 10, learned from 0x12 info frame).
- Show device names from ScanRecord (fixes MAC-only display)
- Show 'Senza nome' for unnamed devices instead of hiding them
- Show proximity (Vicino/Medio/Lontano) instead of raw dBm
- Sort scan results: scale-likely devices first (keyword + UUID scoring)
- Add debug panel (toggle with 🐛 Debug button):
shows GATT service map, raw hex bytes, parse attempts
- Expand parseGeneric: all 2-byte windows × 3 resolutions × LE+BE
(adds 0.1f and big-endian candidates – common in cheap consumer scales)
- Log GATT services/characteristics after connection
- Log raw hex bytes on every characteristic notification
Many consumer scales like LePulse FI2016LB don't advertise standard
Weight Scale (0x181D) or Body Composition (0x181B) service UUIDs.
Remove the scan filter so all BLE devices are discovered.
The GATT fallback already handles proprietary services.
