/**
* An accessibility service runs in the background and receives callbacks by the system
* when {@link AccessibilityEvent}s are fired. Such events denote some state transition
* in the user interface for example the focus has changed a button has been clicked

* of the active window. Development of an accessibility service requires extending this
* class and implementing its abstract methods.
*

* Developer Guides
* For more information about creating AccessibilityServices read the
* Accessibility
* developer guide.

* accessibility service is triggered exclusively by an explicit user action through
* enabling or disabling it in the device settings. After the system binds to a service it
* calls {@link AccessibilityService#onServiceConnected()}. This method can be
* overriden by clients that want to perform post binding setup.
*
* Declaration
*
* An accessibility is declared as any other service in an AndroidManifest.xml but it
* must also specify that it handles the “android.accessibilityservice.AccessibilityService“
* {@link android.content.Intent}. Failure to declare this intent will cause the system to
* ignore the accessibility service. Additionally an accessibility service must request the
* {@link android.Manifest.permission#BIND_ACCESSIBILITY_SERVICE} permission to ensure
* that onl
