Step 5 del wizard ora mostra 4 toggle (pre-compilati se già configurati):
- Salvaschermo orologio (screensaver_enabled)
- Prezzi lista spesa (price_enabled)
- Piano pasti (meal_plan_enabled)
- Suggerimenti zero-waste durante cottura (zerowaste_tips_enabled)
Solo i toggle NON ancora impostati in prefs partono da false (fresh install).
Tutti e 4 vengono salvati in SharedPreferences e inviati al server via
save_settings al completamento del wizard.
PHP/JS: zerowaste_tips_enabled aggiunto come impostazione server-side
(ZEROWASTE_TIPS_ENABLED in .env), sincronizzata nel WebView via
_applySyncedSettings() al caricamento.
webapp:
- Scale indicator: replace plain green dot with ⚖️ emoji + colored
status badge (green/amber/grey/red); icon fades out when disconnected;
tap shows a toast with device name + battery level
- Logo images: crop excess transparent padding from logo.png and
logo_icon.png so content fills the frame at small display sizes
- style.css: reworked .scale-status-indicator CSS for emoji+badge
kiosk:
- SetupActivity: use device's real LAN IP for scale_gateway_url
(was hardcoded 127.0.0.1 — only worked if server and kiosk run on
the same machine); added getDeviceLanIp() helper (prefers wlan/eth)
- activity_setup.xml: reduce welcome step padding/margins so step 1
fits on screen without scrolling; text sizes slightly reduced
- activity_setup.xml: fix feature bullet 'Bilancia Bluetooth via
Gateway app' → 'Bilancia BLE integrata (nessuna app esterna)'
- strings.xml (en + it): rewrite all wizard_gateway_* strings to
reflect integrated BLE service instead of external gateway APK
- ic_logo.png: regenerated at all densities from cropped source
Fallback install (Intent.ACTION_VIEW):
- Remove FLAG_ACTIVITY_NEW_TASK: it caused startActivityForResult to return
RESULT_CANCELED immediately, making the system installer dialog disappear in ~1s
- After fallback returns with app not installed: show '🔄 Riprova installazione'
button that calls tryFallbackInstall() directly (skips PackageInstaller which
is known to give STATUS=1 on this device)
Screensaver:
- KioskActivity.applyScreensaverFlag(): always add FLAG_KEEP_SCREEN_ON, never
clear it — screen must ALWAYS stay on in kiosk mode
- The 'salvaschermo' toggle controls the in-app JS clock overlay (webapp setting),
NOT the Android screen timeout
- finishSetup(): always push screensaver_enabled to webapp API (not just when scale
is configured)
- SettingsActivity save: remove FLAG_KEEP_SCREEN_ON conditional; push
screensaver_enabled to server API on save
- Update setup wizard description + strings to clarify in-app overlay vs screen off
Bump version to 1.5.2 (versionCode 8)
Permissions step:
- Add btnGrantPerms as class field (was only inline findViewById)
- Extract onPermissionsGranted() helper: transforms button to green '✅ Permessi
concessi — Continua →' and sets click listener to showStep(3)
instead of calling onPermissionsGranted() which advances to step 3 (Server)
- Remove the 600ms auto-advance; user controls when to proceed
- Add setup_perms_granted_next string in EN/IT/DE
Network discovery — wrong subnet fix:
- Skip virtual/VPN/cellular interfaces: tun, ppp, rmnet, pdp, ccmni, dummy, sit,
gre, v4-, v6-, p2p, ham, nordlynx prefixes
- Also skip intf.isVirtual interfaces
- Sort: wlan*/eth* interfaces first (highest priority), others after
- Show detected subnet(s) in UI immediately before scan starts
Problems fixed:
- f.get() sequential collection blocked on timed-out futures in submission order
→ replaced with ExecutorCompletionService: results collected as soon as ready
- WifiManager.getConnectionInfo() deprecated on Android 10+, could return IP=0
→ replaced with NetworkInterface.getNetworkInterfaces() for subnet detection
- No real-time feedback: status stuck on 'Scanning…' throughout
→ UI updated every ~120ms showing current IP:port (n/total)
- TCP socket pre-check (600ms) before HTTP probe: filters unreachable hosts instantly
→ reduces scan time from minutes to seconds on typical /24 networks
- executor.shutdownNow() cancels remaining tasks the moment server is found
- 60-thread pool instead of 40 for faster parallel scanning
- Remove unused WifiManager import
- SetupActivity: new Step 0 — language picker (IT/EN/DE) with large buttons,
hardcoded trilingual title so it's always readable; saves 'kiosk_language' pref,
calls recreate() via onSaveInstanceState to reload the Activity in chosen locale
- SetupActivity: new Step 5 — screensaver toggle (before Done), saves 'screensaver_enabled'
- All existing steps shifted: Welcome→1, Permissions→2, Server→3, Scale→4, Done→6
- Progress dots updated to 5 dots (steps 1-5)
- attachBaseContext override in SetupActivity, KioskActivity, SettingsActivity to
apply the saved locale to all Activities via SetupActivity.applyLocale()
- buildSummary now shows language, screensaver setting, and scale status
- New string resources: setup_screensaver_*, summary_lang, summary_scale_skip,
summary_screensaver_on/off in IT, EN, DE
Bug 1 — Uninstall loop (kiosk lock task blocks system uninstall UI):
startActivityForResult(ACTION_DELETE) was called while lock task was
active. The system uninstall activity is not in the lock task whitelist
so it either silently fails or creates an unresolvable loop.
Fix: call disableKioskLock() immediately before every ACTION_DELETE
intent (3 call sites). Call enableKioskLock() at the start of
onActivityResult(UNINSTALL_REQUEST) before retrying install.
Added 600 ms delay after uninstall so PackageManager finishes cleanup.
Bug 2 — Step 2 only checks HTTP connectivity, not PHP API:
testConnection() was checking the root URL only. A generic web server
could pass while the EverShelf PHP API was absent.
Fix: after HTTP 200-399 on the root URL, do a second GET to
/api/?action=check_update and check the response body contains
'latest_tag'|'webapp_version'|'ok'. Shows:
✅ Server EverShelf trovato e API attiva!
⚠ Server raggiungibile ma API PHP non trovata (codice N)
Bug 3 — STATUS_FAILURE=1 even after uninstall (invalid APK file):
GitHub DownloadManager follows redirects; if the release asset does
not exist yet, GitHub returns a 404 HTML page but DownloadManager
still reports STATUS_SUCCESSFUL. PackageInstaller then tries to parse
HTML as an APK and returns STATUS_FAILURE=1.
Fix: validate APK magic bytes (0x504B = 'PK') before calling
installWithPackageInstaller. If invalid: show error, delete corrupt
file, send ErrorReporter event, re-enable retry button.
Also renamed install error string to install_error_install (separate
from install_error_download) for clarity.
Bug 4 — ErrorReporter.serverBaseUrl empty during wizard install:
ErrorReporter.init() is called in onCreate() with the saved URL.
On first setup the URL is typed in step 2 and saved to prefs, but
ErrorReporter still has serverBaseUrl='' for the rest of that session.
Any install error in step 3 silently failed to POST.
Fix: call ErrorReporter.init(this, url) in btnStep2Next immediately
after prefs.edit().putString(KEY_URL, url) so step 3 has a live URL.
Server check (wizard step 3):
- New horizontal card above the scale question always shows server status
as soon as step 3 is entered: ⏳ checking → ✅ reachable / ⚠️ not reachable
- Pings GET $serverUrl/api/?action=check_update (5 s timeout)
- If reachable: 'Error reporting active — failures sent to GitHub Issues'
- If not reachable: 'Check the URL in step 2' warning
- checkServerReachability() called every time goToStep(3) runs
- Strings added in EN / IT / DE
Signature-conflict fallback (else branch in installWithPackageInstaller):
- When PackageInstaller returns a generic STATUS_FAILURE and the target
package is already installed, a signature conflict is the most likely
cause (CONFLICT/INCOMPATIBLE are caught separately earlier)
- New AlertDialog: 'Disinstalla e riprova' → startActivityForResult
ACTION_DELETE → UNINSTALL_REQUEST → auto-retries install on return
- Only shown when all else has already failed
Problem: tapping 'Aggiorna ora' showed a fleeting 'Download avviato'
Toast and then nothing — no feedback on download progress, installer
state, success or failure.
Solution — setInstallUI() central helper:
- Updates the wizard step-3 status card (icon + title + detail line)
OR the update banner (tvUpdateMessage) depending on which is visible
- Always updates and enables/disables the button that triggered the flow
States shown (status card + button text):
⏳ Scaricamento in corso… (download started)
⏳ Installazione in corso… (download done, PackageInstaller running)
⏳ Installazione in corso… + 'Conferma nel dialog…' (user action needed)
✅ Installato con successo! (onActivityResult RESULT_OK or STATUS_SUCCESS)
→ after 3 s auto-refreshes gateway status + closes banner
❌ Download fallito / Installazione non riuscita
→ button re-enabled as '↩ Riprova'
Strings added (EN default + IT + DE):
install_downloading, install_downloading_detail
install_installing, install_confirm_detail
install_success, install_success_detail
install_error_download, install_error_download_detail
install_perm_detail, install_btn_retry
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
Multi-language: strings.xml added for EN (default), IT, DE
strings: wizard_step3_question/yes/no, wizard_gateway_installed/
not_installed/checking/up_to_date/update_available/update_detail,
btn_back/launch/launch_no_scale/download_gateway/update_gateway
- 3-step wizard: Welcome → Server URL → Scale Setup → Launch
- Connection test with live feedback
- BLE scale status during wizard
- Dark theme with modern UI (slate/purple palette)
- Settings page with URL edit, connection test, scale info, wizard reset
- Skip scale option for users without BLE scales
- Error page with retry button when server unreachable
- All UI in English
