Home is the starting place for most applications. (Some applications can be launched only from other applications.) When the user touches an icon in the application launcher (or a shortcut on the Home screen), the main activity for that application is launched into the foreground where it has user focus. As shown in the following figure, the user action of going Home and touching the Email icon launches the List Messages activity of the Email application. The Home activity remains stopped in the background, ready to restart when called on by the user.
