Working with widgets
Widgets are miniature apps that you can place on your Home screens. Some
widgets are standalone applications, some open a related application when you
touch them, and others provide a subset of useful information or controls for their
related applications.
Stock widgets include a clock, a Gmail widget that displays recent messages, a
music player, a picture frame, a calendar that shows upcoming appointments, and
so on. You can also download widgets from Android Market.
Browsing among available widgets and adding, moving, and removing them from
you Home screens is described in “Customizing Home screens” on page 31.
Some widgets simply display information and or act as shortcuts for opening their
applications, such as the Picture Frame widget.
Some widgets give you controls to view and manage their application’s content,
such as the Clock widget or the Music Player widget.
Other widgets, such as the Calendar and Gmail and Email widgets, are like
miniature applications.
You can scroll information displayed by different widgets in different ways, for
example, you can scroll up or down among events in the Calendar widget, or with a
carousel effect in the Books widget.
