It is a hands-on example of various 7 ways to utilize the accessibility API for providing alternative and complementary feedback. 8 The sample demonstrates how to provide application specific feedback — the service 9 handles only accessibility events from the Clock application. Further, the sample demonstrates 10 how to provide dynamic, context-dependent feedback — feedback type changes depending on 11 the ringer mode. 12 </dd> 13</dl> 14 15<dl> 16 <dt><a href="TaskBackService.html">Window Querying Accessibility Service</a></dt> 17 <dd> 18 Demonstrates several new accessibility features in Ice Cream Sandwich, 19 including the ability for an AccessibilityService to traverse the view 20 hierarchy using AccessibilityNodeInfo objects, service configuration via 21 xml files, and adding additional information to AccessibilityEvents using 22 AccessibilityRecords. 23 </dd> 24</dl> 25 26<dl> 27 <dt><a href="CustomViewAccessibilityActivity.html">Custom View Accessibility</a></dt> 28 <dd>Demonstrates how to implement accessibility support of custom views. Custom view 29 is a tailored widget developed by extending the base classes in the android.view 30 package.
