A minimal Android launcher app for MG4 vehicles. It acts as a shortcut that opens the hidden "Track Mode" screen provided by the built-in SAIC maintenance application.
When launched, the app immediately starts the Track Mode activity from the SAIC maintenance package and then closes itself. No user interface is shown.
- Target package:
com.saic.saicmaintenance - Target activity:
com.saicmotor.hmi.trackmode.MainActivity
If the maintenance package is not installed, or the activity cannot be started, a short message is displayed and the app exits.
- An MG4 in-car Android head unit (or a device with the SAIC maintenance app installed)
- Android 9 (API 28) or higher
This is a standard Gradle Android project.
./gradlew assembleDebug
The generated APK can be found under app/build/outputs/apk/.
