| <p>The Android design language relies on traditional typographic tools such as scale, space, rhythm, |
| and alignment with an underlying grid. Successful deployment of these tools is essential to help |
| users quickly understand a screen of information. To support such use of typography, Ice Cream |
| Sandwich introduced a new type family named Roboto, created specifically for the requirements of UI |
| and high-resolution screens. The current TextView framework supports regular, bold, italic, and bold |
| italic weights by default.</p> |

| <h4>Default type colors</h4> |
| <p>The Android UI uses the following default color styles: <code>textColorPrimary</code> and |
| <code>textColorSecondary</code>. For light themes use <code>textColorPrimaryInverse</code> and |
| <code>textColorSecondaryInverse</code>. The framework text color styles also support variants for |
| touch feedback states when used inside UI elements.</p> |

| |
| <h4>Typographic Scale</h4> |
| <p>Contrast in type sizes can go a long way to create ordered, understandable layouts. However, too |
| many different sizes in the same UI can be messy. The Android framework uses the following limited |
| set of type sizes:</p> |
| |
| <img src="../static/content/typography_sizes.png"> |
| |
| <p>Users can select a system-wide scaling factor for text in the Settings app. In order to support |
| these accessibility features, type should be specified in scale-independent pixels |
| (<acronym title="Scale-independent pixels. One sp is one pixel on a 160 dpi screen if the user's global text scale is set to 100%.">sp</acronym>) |
| wherever possible. Layouts supporting scalable types should be tested against these settings.</p> |
