- * An accessibility service runs in the background and receives callbacks by the system

  * <h3>Lifecycle</h3>
  * <p>
  * The lifecycle of an accessibility service is managed exclusively by the system and
- * follows the established service life cycle. Additionally, starting or stopping an
- * 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.

+ * An accessibility service stops either when the user turns it off in device settings or when
+ * it calls {@link AccessibilityService#disableSelf()}.
  * </p>
  * <h3>Declaration</h3>
  * <p>
- * 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 only the system
- * can bind to it. Failure to declare this intent will cause the system to ignore the

+ * A service can specify in its declaration that it can retrieve window
+ * content which is represented as a tree of {@link AccessibilityWindowInfo} and
+ * {@link AccessibilityNodeInfo} objects. Note that
  * declaring this capability requires that the service declares its configuration via
  * an XML resource referenced by {@link #SERVICE_META_DATA}.
  * </p>
  * <p>
- * For security purposes an accessibility service can retrieve only the content of the
- * currently active window. The currently active window is defined as the window from
- * which was fired the last event of the following types:
- * {@link AccessibilityEvent#TYPE_WINDOW_STATE_CHANGED},
- * {@link AccessibilityEvent#TYPE_VIEW_HOVER_ENTER},
- * {@link AccessibilityEvent#TYPE_VIEW_HOVER_EXIT},
- * In other words, the last window that was shown or the last window that the user has touched
- * during touch exploration.
- * </p>
- * <p>
- * The entry point for retrieving window content is through calling
- * {@link AccessibilityEvent#getSource() AccessibilityEvent.getSource()} of the last received
- * event of the above types or a previous event from the same window
- * (see {@link AccessibilityEvent#getWindowId() AccessibilityEvent.getWindowId()}). Invoking
- * this method will return an {@link AccessibilityNodeInfo} that can be used to traverse the
- * window content which represented as a tree of such objects.
+ * Window content may be retrieved with
+ * {@link AccessibilityEvent#getSource() AccessibilityEvent.getSource()},
+ * {@link AccessibilityService#findFocus(int)},
+ * {@link AccessibilityService#getWindows()}, or
+ * {@link AccessibilityService#getRootInActiveWindow()}.
  * </p>
  * <p class="note">
  * <strong>Note</strong> An accessibility service may have requested to be notified for
- * a subset of the event types, thus be unaware that the active window has changed. Therefore
- * accessibility service that would like to retrieve window content should:
- * <ul>
- * <li>
- * Register for all event types with no notification timeout and keep track for the active
- * window by calling {@link AccessibilityEvent#getWindowId()} of the last received event and
- * compare this with the {@link AccessibilityNodeInfo#getWindowId()} before calling retrieval
- * methods on the latter.
- * </li>
- * <li>
- * Prepare that a retrieval method on {@link AccessibilityNodeInfo} may fail since the
- * active window has changed and the service did not get the accessibility event yet. Note
- * that it is possible to have a retrieval method failing even adopting the strategy
- * specified in the previous bullet because the accessibility event dispatch is asynchronous
- * and crosses process boundaries.
- * </li>
- * </ul>
+ * a subset of the event types, and thus be unaware when the node hierarchy has changed. It is also
