What Does Tasker Do ? Tasker performs Tasks (sets of basic actions) based on Contexts (application, time, date, location, event, state, voice command, gesture, shortcut, widget press/timer expiry). Contexts are ordered into groups and connected to tasks in units called Profiles. When all of the contexts in a Profile are active, its Enter task runs. When it's no longer active, its Exit task runs. Example Profile Contexts: (Application) Browser (Time) 9:00 - 17:00 Enter Task: WiFi, On Flash, "Happy Browsing" Exit Task: Flash, "Goodbye" When the application Browser is started betweeen 9:00 and 17:00 WiFi is automatically enabled and "Happy Browsing" flashes up briefly. When Browser is no longer running, or the time is no longer between 9:00 and 17:00, "Goodbye" flashes up briefly and WiFI is restored to its previous setting (because Wifi is a settings action, marged with a cog icon, which are automatically restored). More Information the Guides page is a good starting place. You can download profiles for common tasks via Menu / Browse Examples Tasker also includes a built-in Userguide plus a help text for each screen, accessed via the Menu key (or the overflow icon in the action bar). See the User Support info if you have questions or problems.
