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

application, stopping and starting them as 
needed to ensure that idle applications don’t 
consume resources unnecessarily.
