- 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)
EverShelf Kiosk
Android kiosk app for wall-mounted kitchen tablets. A pure full-screen WebView wrapper that displays the EverShelf web interface in immersive mode — no BLE, no gateway, just the web app locked to screen.
Version: 1.2.0 (versionCode 3)
Package:it.dadaloop.evershelf.kiosk
Features
- Full-screen WebView — immersive mode hides status bar and navigation bar
- True kiosk lock — screen pinning (
startLockTask) blocks home/recent/back buttons - 3-step setup wizard — Welcome → Server URL (with connection test) → Scale Gateway detection
- Gateway auto-launch — starts EverShelf Scale Gateway in background on boot
- Exit button (✕) — visible in header, requires confirmation dialog to exit kiosk
- Hard refresh (↻) — clears WebView cache to pick up web app updates instantly
- Camera & microphone — runtime permission handling for barcode scanning and voice
- SSL support — accepts self-signed certificates for local HTTPS servers
- Splash screen — branded 1.5-second splash on startup
- Update notifications — checks GitHub releases every 6 hours, shows auto-dismiss banner
- Settings activity — change server URL, test connection, re-run setup wizard
- Error recovery — retry page when server is unreachable

EverShelf Scale Gateway (separate app, runs in background)
The kiosk app does not contain any BLE or scale code. Scale functionality is handled entirely by the separate EverShelf Scale Gateway app.
Setup
- Install both APKs on your Android tablet:
- EverShelf Kiosk (this app)
- EverShelf Scale Gateway (optional, for smart scale support)
- Launch the kiosk app — the setup wizard starts automatically
- Enter your EverShelf server URL (e.g.
https://192.168.1.100/dispensa) - The wizard tests the connection and detects the gateway app
- Done — the web app loads in full-screen kiosk mode
Exiting Kiosk Mode
Tap the ✕ button in the header (left of the title). A confirmation dialog appears — tap "Esci" to exit.
Triple-tap (Developer)
Triple-tap the setup wizard title to access hidden settings.
