Two bugs caused the gateway APK install to always fail with status=1:
1. setAppPackageName() removed from SessionParams
This optional call forces the installer to verify the package name
against the APK's manifest. On some OEM/Android versions this
comparison fails even when the name is correct, returning the generic
STATUS_FAILURE (1) with no EXTRA_STATUS_MESSAGE. Removing it lets
the installer proceed without the extra check.
2. BroadcastReceiver was unregistered on STATUS_PENDING_USER_ACTION
On Android 11+ the final install result (STATUS_SUCCESS/STATUS_FAILURE)
arrives as a SECOND broadcast AFTER the user confirms the dialog.
The receiver was being unregistered immediately on the first broadcast
(PENDING_USER_ACTION), so the final result was never received.
Fix: only unregister on terminal statuses (SUCCESS, FAILURE, ABORTED).
Additional improvements:
- STATUS_FAILURE_ABORTED (-1) handled explicitly: resets UI without
showing an error (user just pressed back on the confirmation dialog)
- session.abandon() called on exception instead of letting .use{} close
- ErrorReporter now includes apk_kb and android API level in context
- onActivityResult(INSTALL_CONFIRM_REQUEST) no longer sets success/failure
UI (the BroadcastReceiver is responsible for the final result)
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

├── Setup wizard (3 steps, shown on first launch only)
├── Immersive mode (SYSTEM_UI_FLAG_IMMERSIVE_STICKY)
├── Screen pinning (startLockTask / stopLockTask)
├── JS bridge (_kioskBridge: exit, hardReload)
├── Header injection (✕ exit + ↻ refresh buttons)
└── Gateway launcher (launches gateway APK in background)
↓ FLAG_ACTIVITY_NEW_TASK
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.
