Successful deployment of these tools is essential to help 20 users quickly understand a screen of information. To support such use of typography, Ice Cream 21 Sandwich introduced a new type family named 22 <a href="http://www.google.com/fonts/specimen/Roboto" class="external-link">Roboto</a>, created 23 specifically for the requirements of UI and high-resolution screens.</p> 24 25 <p>The current {@link android.widget.TextView} framework offers Roboto in thin, light, regular and bold 26 weights, along with an italic style for each weight.
