On a rooted device the app now runs the full silent onboarding on launch
with no taps: a LaunchedEffect auto-starts the root sequence once when
root is detected and this host hasn't been onboarded yet. The root-auto
logic is extracted into a reusable runRootAuto lambda (shared by the
auto-launch and the ⚡ button, which remains for re-runs). An onboarded
flag is persisted per host in SharedPreferences so reopening doesn't redo
it. versionName 0.2.0 / versionCode 2.

SecuBox Android ToolBox client (#531)
One-tap R3 onboarding for the VILLAGE3B cabine : install the CA, import the WireGuard profile, verify the tunnel, then open the live cartographie sociale. Replaces the manual Android tutorial.
Flow (manual path)
- Discover — scan the kbin QR or type the booth host (
kbin.gk2.secubox.in). - Install CA — downloads
/wg/ca.crt, launches the Android cert-install intent (KeyChain.createInstallIntent). - Import profile — downloads
/wg/profile/new, hands the.confto the WireGuard app viaFileProvider+ACTION_VIEW. - Verify — polls
/wg/r3-check→ "Tunnel R3 actif ✓". - Live metrics — opens
/social/me(cartographie sociale).
Root path — fully-automated silent onboarding (#538, #551)
When the device is rooted, the app runs the whole onboarding with zero
taps: on launch it auto-detects root and, if this cabine host hasn't been
onboarded yet, starts the silent sequence automatically (RootAuto step,
streaming log). The ⚡ Installation automatique (root) button stays for
re-runs. The "already onboarded" flag is persisted per host (SharedPreferences)
so reopening the app doesn't redo it. Steps:
- System CA install — downloads
/wg/ca.pem, computes the OpenSSLsubject_hash_oldin pure Kotlin, and bind-mounts a populated copy of the trust store over/system/etc/security/cacerts(+ the conscrypt APEX path on Android 14), restoring the SELinux context (u:object_r:system_security_cacerts_file:s0). Every app trusts the cabine CA — not just user-CA opt-in apps. Reversible viaumount. - Native WireGuard — if the kernel has the WireGuard module +
wg/ip, brings the tunnel up natively (ip link add … type wireguard+wg set), no WireGuard app required. - Auto R3 verify — polls
/wg/r3-check.
Fallback — if the kernel lacks WireGuard, the root path installs the system CA then hands off to the manual WireGuard-app flow (steps 3–5 above).
All root actions are gated behind the explicit tap — nothing runs as
root without the operator choosing root mode on their own device.
See RootShell.kt (su wrapper) and RootOnboard.kt (silent sequence).
Build
No Gradle wrapper jar is committed (text-only scaffold). CI builds it:
- GitHub Actions
build-android-apk.yml→ debug APK artifact. Locally (with Android SDK + Gradle 8.9 + JDK 17):
cd clients/android-toolbox
gradle :app:assembleDebug # app/build/outputs/apk/debug/app-debug.apk
Constraints (MVP)
- Android 11+ restricts user CA trust ; the manual path launches the install intent + guides the confirm step. Browsers on the device need the CA trusted for the mitm R3 break — this is the known Android limitation on non-rooted devices. Rooted devices bypass it entirely via the system CA install (see Root path above).
- The manual path imports the WireGuard profile via the official WireGuard app (no embedded tunnel) — most reliable, no extra native deps. The root path brings the tunnel up natively with the kernel module.
- Debug APK is self-signed (sideload). Release signing (published fingerprint, served from the toolbox) is a follow-up needing a keystore secret in CI.
Tech
Kotlin + Jetpack Compose, minSdk 26 / targetSdk 34. API client is plain
HttpURLConnection (no Retrofit/OkHttp) to keep deps + CI minimal.
