6. Opening and switching applications
Multi-tasking is easy with Android because you can keep more than one application
running at the same time. There is no need to quit an application before opening
another one. 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.
