fr3ts0n/AndrOBD ? reverse-engineered prompt

Build me an Android app for car diagnostics that connects to an ELM327 OBD adapter over Bluetooth, USB, or Wi Fi and shows the important vehicle info in a simple, modern way. I want it to read and clear fault codes, show live sensor data, freeze frame info, and basic vehicle details, with charts, a dashboard view, and a head up display mode. It should also have a demo mode so I can try it without any adapter. Let me record data, view saved recordings later, and export to CSV. If possible, make the screens feel more up to date and easy to use, and keep it ready for translation into different languages. If you need to check current Android docs or best practices, go ahead and look them up online.
