Successful deployment of these tools is essential to help 14 users quickly understand a screen of information. To support such use of typography, Ice Cream 15 Sandwich introduced a new type family named Roboto, created specifically for the requirements of UI 16 and high-resolution screens. The current TextView framework supports regular, bold, italic, and bold 17 italic weights by default.</p> 18 19 <img src="{@docRoot}design/media/typography_alphas.png"> 20 21 <p><a href="{@docRoot}downloads/design/Roboto_Hinted_20111129.zip">Download Roboto</a></p> 22 <p><a href="{@docRoot}downloads/design/Roboto_Specimen_Book_20111129.pdf">Specimen Book</a></p> 23 24 </div> 25 </div> 26 27 <hr> 28 29 <div class="layout-content-row"> 30 <div class="layout-content-col span-6"> 31 32 <h4>Default type colors</h4> 33 <p>The Android UI uses the following default color styles: <code>textColorPrimary</code> and 34 <code>textColorSecondary</code>.

However, too 45 many different sizes in the same UI can be messy. The Android framework uses the following limited 46 set of type sizes:</p> 47 48 <img src="{@docRoot}design/media/typography_sizes.png"> 49 50 <p>Users can select a system-wide scaling factor for text in the Settings app. In order to support 51 these accessibility features, type should be specified in scale-independent pixels 52 (<acronym title="Scale-independent pixels.
