setBackground()

Sets the action to run as a background action. This cannot be unset. Background actions are usually long running and lower priority actions. A background action is useful when you want your app to remain responsive to a user while it executes a low priority, long-running action. A rough guideline is to use a background action if it takes more than five seconds for the response to return from the server.
