Wizard step 3 — 'Do you have a Bluetooth smart scale?':
- New question card with two buttons shown first:
✅ Yes → reveal gateway status card + bottom nav buttons
➡️ No → save KEY_HAS_SCALE=false, skip to web view
- KEY_HAS_SCALE pref controls whether the gateway is auto-launched
both after wizard completion and on every subsequent app start
- checkGatewayStatus(): uses string resources (multilingual)
- checkGatewayUpdate(): fetches GitHub release, compares version;
if gateway needs an update shows '📥 Update Scale Gateway' button
that triggers triggerApkDownload() (full PackageInstaller flow)
- onResume step-3 re-check only fires when status card is visible
(i.e. user already answered 'Yes') — handles return from 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.
