# 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](../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
|
|
|
|
## Architecture
|
|
|
|
```
|
|
KioskActivity (WebView — full-screen EverShelf)
|
|
├── 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](../evershelf-scale-gateway/) app.
|
|
|
|
## Setup
|
|
|
|
1. Install both APKs on your Android tablet:
|
|
- **EverShelf Kiosk** (this app)
|
|
- **[EverShelf Scale Gateway](../evershelf-scale-gateway/)** (optional, for smart scale support)
|
|
2. Launch the kiosk app — the setup wizard starts automatically
|
|
3. Enter your EverShelf server URL (e.g. `https://192.168.1.100/dispensa`)
|
|
4. The wizard tests the connection and detects the gateway app
|
|
5. 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.
|
|
