7. Opening and switching
applications
Multitasking is easy with Android because
you can keep more than one application
running at the same time. There's no
need to quit an application before opening
another. Use and switch between several
open applications. Android manages each
application, stopping and starting them
as needed to ensure that idle applications
don't consume resources unnecessarily.
To return to view list recently used
applications:
Simply press and hold the Home key.
To stop applications:
1
Touch > Apps tab > Settings >
Apps > Running from the DEVICE
2
Scroll and touch the desired applica-
tion and touch Stop to stop it.
