Switching between and exiting applications
Multi-tasking is easy with Android because open applications keep running even when you
open another application. There is no need to quit an application before opening another.
Use and switch among several open applications. Android manages each application,
stopping and starting them as needed, to ensure that idle applications don’t consume
resources unnecessarily.
Switching between applications 
Touch and hold the
Home Key
. A list of recently used applications will be
displayed. Then tap the application you want to access.
To remove an application from the list, swipe the app preview to the left or right.
To stop/exit an application 
From the Home screen, tap the
Menu Key
and tap
System settings > Apps.
Tap one of the tabs at the top of the screen, choose the desired application and tap
Force stop (or Stop) to stop the application.
