This is the first driver-app skeleton. It uses a foreground service, Android's native LocationManager, and HttpURLConnection so the MVP has no runtime library dependencies beyond the Android Gradle/Kotlin plugins.

Build

Open apps/android in Android Studio, sync Gradle, then run the app module. For command-line debug builds:

$env:JAVA_HOME="C:\Program Files\Android\Android Studio\jbr"
$env:ANDROID_HOME="$env:LOCALAPPDATA\Android\Sdk"
.\gradlew.bat :app:assembleDebug

The debug APK is created at:

apps/android/app/build/outputs/apk/debug/app-debug.apk

Current Gradle plugin choices:

Android Gradle Plugin: 9.2.0
Kotlin: built into Android Gradle Plugin 9.x
Gradle wrapper: 9.4.1
compile/target SDK: 36

MVP behavior

The app asks for foreground location and notification permissions.
Press 운행 시작 to start a location foreground service.
The service uploads location JSON to /api/v1/locations.
Failed uploads are queued locally and retried after the next successful send.
Press 운행 종료 to stop location updates.

For emulator testing, keep the default server URL http://10.0.2.2:8080. For a real phone, use the NAS or PC LAN URL, for example http://192.168.200.129:18081.

The current public reverse-proxy URL is https://cargoradar.comtropy.synology.me.

Production builds should use HTTPS and disable cleartext traffic.
