Tasker is an Android program that allows you to program your phone to perform actions automatically

Create a shortcut to a Task
Tasker displays a lightning bolt icon at the top of the screen when it is enabled. If Tasker is accidently disabled, this icon is not displayed and Tasker does not automatically perform tasks.
To enable Tasker, open the application and long press the lightning bold icon at the top left of the screen. If the icon is grayed out, that indicates that Tasker is not enabled. A long press turns on the enabled status. A long press when it is enabled disables Tasker and grays out the icon.
