| <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 |
| items. For example, in the Gmail app, each message has a star icon that marks the message as |
| important.</p> |

| <p>Use non-neutral colors sparingly and with purpose. For example, Gmail uses yellow in the star icon |

| the background.</p> |
