<p>Themes are Android's mechanism for applying a consistent style to an app or activity. The style
specifies the visual properties of the elements that make up your user interface, such as color,
height, padding and font size. To promote greater cohesion between all apps on the platform, Android
provides three system themes that you can choose from when building apps for Ice Cream Sandwich:</p>
<ul>
<li>Holo Light</li>
<li>Holo Dark</li>
<li>Holo Light with dark action bars</li>
</ul>
<p>Applying these themes will go a long way in helping you to build apps that fit right into the
general visual language of Android.</p>
<p>Pick the system theme that best matches the needs and design aesthetics for your app. If your
desire is to have a more distinct look for your app, using one of the system themes as a starting
point for your customizations is a good idea. The system themes provide a solid foundation on top
of which you can selectively implement your own visual stylings.</p>
