Dan Gookin - Android For Dummies

For older Androids that lack the Recent navigation icon, long-press the Home navigation icon to see the Overview.

The Android operating system may shut down apps that haven’t received attention for a while. Don’t be surprised when you can’t find a recent app on the Overview. If so, just start it again as you normally would.

The Android operating system features a consistent armada of helpful icons. These icons serve common and consistent functions in apps as well as in the Android operating system. Table 3-2lists the most common of these icons and their functions.

TABLE 3-2Common Icons

Icon	Name	What It Does
	Action Overflow	Displays a list of actions, similar to a menu.
	Add	Adds or creates an item. The plus symbol (+) may be used in combination with other symbols, depending on the app.
	Chevron	Points in various directions to expand or collapse a card, menu, or list or another item. This icon might also appear as a solid triangle.
	Close	Dismisses a card, clears text from an input field, or removes an item from a list.
	Delete	Removes one or more items from a list or deletes a message.
	Dictation	Activates voice input.
	Done	Dismisses the action bar or confirms and saves edits.
	Edit	Edits an item, adds text, or fills in fields.
	Favorite	Flags a favorite item, such as a contact or a web page.
	Refresh	Fetches new information or reloads.
	Search	Searches the screen, the device, or the Internet for a tidbit of information.
	Settings	Adjusts options for an app.
	Share	Shares information via a specific app, such as Gmail or Facebook.
	Side Menu	Opens the navigation drawer, which is available in most Android apps. This icon is also called the hamburger.

Various sections throughout this book give examples of using these icons. Their images appear in the book’s margins where relevant.

Some Androids offer a Help app or provide help in the Settings app, which lists all available icons and their functions. This list may include notification and status icons as well.

Other common symbols are used on icons in various apps. For example, the standard Play and Pause icons are used as well.

The Share icon, shown in Table 3-2, has an evil twin, shown in the margin. Both icons represent the Share action.

Some gizmos use text buttons instead of icons. For example, on Samsung devices, the MORE button appears in place of the Action Overflow icon. In fact, you often see text buttons such as SAVE or DONE instead of icons.

Another variation on the Settings icon is shown in the margin. It serves the same purpose as the Gear icon (refer to Table 3-2), though this older icon is being phased out.
