  - DEFAULT
```
public static final int DEFAULT
```
    If an AccessibilityService is the default for a given type. Default service is invoked only if no package specific one exists. In case of more than one package specific service only the earlier registered is notified.
    
    See Also:
    Constant Field Values
  - FLAG_INCLUDE_NOT_IMPORTANT_VIEWS
```
public static final int FLAG_INCLUDE_NOT_IMPORTANT_VIEWS
```
    If this flag is set the system will regard views that are not important for accessibility in addition to the ones that are important for accessibility. That is, views that are marked as not important for accessibility via View.IMPORTANT_FOR_ACCESSIBILITY_NO and views that are marked as potentially important for accessibility via View.IMPORTANT_FOR_ACCESSIBILITY_AUTO for which the system has determined that are not important for accessibility, are both reported while querying the window content and also the accessibility service will receive accessibility events from them.
    Note: For accessibility services targeting API version Build.VERSION_CODES#JELLY_BEAN or higher this flag has to be explicitly set for the system to regard views that are not important for accessibility. For accessibility services targeting API version lower than Build.VERSION_CODES#JELLY_BEAN this flag is ignored and all views are regarded for accessibility purposes.
    
    Usually views not important for accessibility are layout managers that do not react to user actions, do not draw any content, and do not have any special semantics in the context of the screen content. For example, a three by three grid can be implemented as three horizontal linear layouts and one vertical, or three vertical linear layouts and one horizontal, or one grid layout, etc. In this context the actual layout mangers used to achieve the grid configuration are not important, rather it is important that there are nine evenly distributed elements.
    
    See Also:
    Constant Field Values
  - FLAG_REQUEST_TOUCH_EXPLORATION_MODE
```
public static final int FLAG_REQUEST_TOUCH_EXPLORATION_MODE
```
    This flag requests that the system gets into touch exploration mode. In this mode a single finger moving on the screen behaves as a mouse pointer hovering over the user interface. The system will also detect certain gestures performed on the touch screen and notify this service. The system will enable touch exploration mode if there is at least one accessibility service that has this flag set. Hence, clearing this flag does not guarantee that the device will not be in touch exploration mode since there may be another enabled service that requested it.

    Constant Field Values
  - eventTypes
```
public int eventTypes
```
    The event types an AccessibilityService is interested in.
    Can be dynamically set at runtime.
    
    See Also:
    AccessibilityEvent.TYPE_VIEW_CLICKED, AccessibilityEvent.TYPE_VIEW_LONG_CLICKED, AccessibilityEvent.TYPE_VIEW_FOCUSED, AccessibilityEvent.TYPE_VIEW_SELECTED, AccessibilityEvent.TYPE_VIEW_TEXT_CHANGED, AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED, AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED, AccessibilityEvent.TYPE_TOUCH_EXPLORATION_GESTURE_START, AccessibilityEvent.TYPE_TOUCH_EXPLORATION_GESTURE_END, AccessibilityEvent.TYPE_VIEW_HOVER_ENTER, AccessibilityEvent.TYPE_VIEW_HOVER_EXIT, AccessibilityEvent.TYPE_VIEW_SCROLLED, AccessibilityEvent.TYPE_VIEW_TEXT_SELECTION_CHANGED, AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED
  - packageNames
```
public String[] packageNames
```
    The package names an AccessibilityService is interested in. Setting to null is equivalent to all packages.
    Can be dynamically set at runtime.
  - feedbackType
```
public int feedbackType
```
    The feedback type an AccessibilityService provides.
    Can be dynamically set at runtime.
    
    See Also:
    FEEDBACK_AUDIBLE, FEEDBACK_GENERIC, FEEDBACK_HAPTIC, FEEDBACK_SPOKEN, FEEDBACK_VISUAL, FEEDBACK_BRAILLE
  - notificationTimeout
```
public long notificationTimeout
```
    The timeout after the most recent event of a given type before an AccessibilityService is notified.
    Can be dynamically set at runtime..
    
    Note: The event notification timeout is useful to avoid propagating events to the client too frequently since this is accomplished via an expensive interprocess call. One can think of the timeout as a criteria to determine when event generation has settled down.
  - flags
```
public int flags
```
    This field represents a set of flags used for configuring an AccessibilityService.
    Can be dynamically set at runtime.
