Remarks

System level service that serves as an event dispatch for AccessibilityEvents, and provides facilities for querying the accessibility state of the system. Accessibility events are generated when something notable happens in the user interface, for example an android.app.Activity starts, the focus or selection of a android.view.View changes etc. Parties interested in handling accessibility events implement and register an accessibility service which extends android.accessibilityservice.AccessibilityService.
