AppSwitcher

AppSwitcher is an app launcher designed for automotive head units that allow to set a steering wheel button to run this app!

AppSwitcher enhances your steering wheel key to let you switch between apps.
Hereby you can select which apps should be offered and you can choose stock apps (e.g. the radio app) and 3rd party apps like your favorite MP3 or DAB Player. You can switch between media and navigation apps by a single key press.
Additionally it's possible to run the last used media app, dim the screen brightness during night and run custom automations.

AppSwitcher does not(!) replace your home launcher as the idea is only to offer a smarter way to switch between apps.

Please note:
Depending on your head unit, the setup of this app can vary from super easy to (almost) impossible. This fully depends on the provided customization options provided by your head unit. It's always a good idea to visit the xdaforum in case of questions and problems:
