     25 <p>When it comes to reaching as wide a userbase as possible, it's important to
     26 pay attention to accessibility in your Android application.  Cues in your user
     27 interface that may work for a majority of users, such as a visible change in
     28 state when a button is pressed, can be less optimal if the user is visually
     29 impaired.</p>

     31 <p>This class shows you how to make the most of the accessibility features
     32 built into the Android framework.  It covers how to optimize your app for
     33 accessibility, leveraging platform features like focus navigation and content
     34 descriptions.  It also covers how to build accessibility services, that can
     35 facilitate user interaction with <strong>any</strong> Android application, not
     36 just your own.</p>

     49     mines those events for information like event type and content descriptions,
     50     and uses that information to communicate with the user.  The example will
