Install Android Auto on Graphene
Graphene OS Supports Android Auto
Android Auto
Graphene OS provides an option to install and use the official release of Android Auto. Android Auto requires privileged access in order to work. Graphene OS uses an extension of the sandboxed Google Play compatibility layer to make Android Auto work with a reduced level of privileges.
To Install Android Auto
To install Android Auto, use the Graphene OS App Store app. Android Auto can't be installed through the Play Store or other app sources. Android Auto depends on sandboxed Google Play, you'll be prompted to install it if it's not already installed.
To Configure Android Auto
After installation, Android Auto has to be set up from the Settings > Apps > Sandboxed Google Play > Android Auto configuration screen, which contains permission toggles, links to related configuration screens, configuration tips, and links to optional Android Auto dependencies. The permission toggles ask for a confirmation before turning on. The confirmation popup explains what access each permission toggle provides. By default, Android Auto is not granted any kind of privileged access. It's treated the same way other apps are treated to improve privacy and security compared to standard phone installations of Android Auto.
In order to work, Android Auto has to be granted baseline permissions for wired or wireless Android Auto. Wired Android Auto requires far less access than wireless Android Auto does. Baseline permissions are controlled by the "Allow permissions for wired / wireless Android Auto" toggles. For some cars, baseline permissions for wireless Android Auto are needed even when using wired Android Auto. Therefore, if wired Android Auto is unable to connect to the car with only wired permissions granted, try granting wireless permissions instead.
To forward notifications from the device to the car, Android Auto has to be allowed notification access. The notification access settings are linked below the permission toggles. In order to show up in the Android Auto car interface, apps have to be installed from the Play Store and include Android Auto support.
