Arkasha18/H9-cluster ? reverse-engineered prompt

Build me an unofficial digital instrument cluster app for a Haval H9 head unit running Android 9, made for a second display at 1920 by 720.

I want it to show the usual driving info in a clean car dashboard style, speed, RPM, odometer, fuel level and range, coolant and outside temp, transmission oil temp, steering angle, tire pressures, wheel speeds, fuel consumption, and battery voltage. It should let the user pick from several visual themes, including Classic, Sport, Horizon, Simple, ION AURORA, Sculpted Titanium, and APEX SPORT, and let them switch between real speed and the factory style offset. It also needs a setting to choose between 80 liter and 60 liter tank calibration, plus an option to hide the gear number if the car already shows it elsewhere.

Please make it launch automatically on the second screen, keep the stock panel option available, and include a settings screen with update checking and safe APK install flow for release builds. If you need to, look up current Android docs online and keep it working nicely on modern devices.
