Qt-Advanced-Docking-System VS openauto

Personally, I'm partial to the PyO3+PyQt/PySide option because Qt's QWidget APIs are a very polished and mature way to build a portable "as native as feasible without writing a separate frontend for each platform" GUI with great quality-of-life things like QMainWindow::saveState, PyQt-compatible bindings for addons like Qt Advanced Docking System, and tooling like MyPy. (It also helps that, as a KDE user, QWidget is the platform's native UI API.)

Clone it into a subdirectory and then add it via add_subdirectory(Qt-Advanced-Docking-System). Then add it to your app via target_link_libraries(MyAppName PRIVATE qtadvanceddocking) as seen in https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/blob/master/examples/simple/CMakeLists.txt.

Options are limited. Look here: https://github.com/f1xpl/openauto

Other than a DIY solution then possibly Open Auto (free and paid) could help?

It would take a lot of time don't get me wrong & it can replace your infotainment center with a touchscreen & a rPi3B running OpenAutoPro but if you look at that feature set in the repo you'll see why it's wayyy better & integrates your android on multiple abstraction layers instead of just bluetooth. Plus the user interface is fully customizable with Qt (all open source)

Actually, maybe it's possible? This project seems like it could run on the Car Thing. https://github.com/f1xpl/openauto

I dunno if this is the proper place to ask about this, but; we already know Android Auto is pretty locked down to Googly's services, and requires their apps for the extra functionality. I'm aware of some progress being made to work around it; someone did get Android Auto Running in MicroG as well as AACS and the wonderful reverse engineered OpenAuto

I also tried sudo apt install https://github.com/f1xpl/openauto
