Currently, you need to design versions of your settings screens for both portrait and landscape layouts:
A portrait-mode layout for the screen size used in the Volvo Polestar 2 (1068 x 1425dp; 1152 x 153px)
A landscape-mode layout for the screen size used in Google's reference Automotive implementation (1075 x 806dp; 1024 x 768px)
You can use the emulator in Android Studio to see how your layouts look in these two implementations. You can also consult Layout for reference information about how car makers’ layouts are adapted to various screen sizes (keeping in mind that details such as margins and padding values may be changed by the car maker).
Include only settings that are necessary for app use (such as account info, app preferences, and sign-in/sign-out) or relevant to listening to media in the car (for example, turning off explicit content)
Make all settings accessible from a single screen, if possible
Avoid use of dialogs beyond simple confirmation
Design for cars: Keep in-car settings to the minimum required for that environment, and make them easy to find and use.
