<p>An icon is a graphic that takes up a small portion of screen real estate and provides a quick,

intuitive representation of an action, a status, or an app.</p>

|
|
|
|
<h2 id="launcher">Launcher</h2>
|

<p>The launcher icon is the visual representation of your app on the Home or All Apps screen. Since the

user can change the Home screen's wallpaper, make sure that your launcher icon is clearly visible on
|
|
any type of background.</p>

<h2 id="actionbar">Action Bar</h2>
|
|
|
|
<p>
|
|
|
|
Action bar icons are graphic buttons that represent the most important actions people can take
|
|
within your app. Each one should employ a simple metaphor representing a single concept that most
|
|
people can grasp at a glance.
|
|
|
|
</p>
|
|
<p>
|
|
|
|
Pre-defined glyphs should be used for certain common actions such as "refresh" and "share." The
|
|
download link below provides a package with icons that are scaled for various screen densities and
|
|
are suitable for use with the Holo Light and Holo Dark themes. The package also includes unstyled
|
|
icons that you can modify to match your theme, in addition to Adobe® Illustrator® source
|
|
files for further customization.

<p>Within the body of your app, use small icons to surface actions and/or provide status for specific

important.</p>
