## Overview
HomeScreen is built with a GUI application created with Qt(referred as HomeScreenGUI), and a service running on afb-daemon (referred as HomeScreenBinder).
HomeScreen can start/switch applications run in AGL, also displays information such as onscreen messages.
You can find these projects in AGL gerrit.
