To promote greater cohesion between all apps 23 on the platform, Android provides two system themes that you can choose from when building apps:</p> 24 <ul> 25 <li>Holo Light</li> 26 <li>Holo Dark</li> 27 </ul> 28 <p>Applying these themes will go a long way in helping you to build apps that fit right into the 29 general visual language of Android.</p> 30 <p>Pick the system theme that best matches the needs and design aesthetics for your app. If your 31 desire is to have a more distinct look for your app, using one of the system themes as a starting 32 point for your customizations is a good idea. The system themes provide a solid foundation on top 33 of which you can selectively implement your own visual stylings.</p> 34 35 <div class="note develop"> 36 <p><strong>Developer Guide</strong></p> 37 <p>For information about how to apply themes such as Holo Light and Dark, and 38 how to build your own themes, see the 39 <a href="{@docRoot}guide/topics/ui/themes.html">Styles and Themes</a> API guide.</p> 40 </div> 41 42 </div> 43 </div> 44
