This class describes an AccessibilityService. The system notifies an AccessibilityService for AccessibilityEvents according to the information encapsulated in this class.
For more information about creating AccessibilityServices, read the Accessibility developer guide.

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.
Mask for all feedback types.
Denotes audible (not spoken) feedback.
Denotes braille feedback.
Denotes generic feedback.
Denotes haptic feedback.
Denotes spoken feedback.
Denotes visual feedback.
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 IMPORTANT_FOR_ACCESSIBILITY_NO and views that are marked as potentially important for accessibility via 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 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 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.
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.

Can be dynamically set at runtime.
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.
The package names an AccessibilityService is interested in. Setting to null is equivalent to all packages.
Can be dynamically set at runtime.
Describe the kinds of special objects contained in this Parcelable's marshalled representation.
Returns the string representation of a feedback type. For example, FEEDBACK_SPOKEN is represented by the string FEEDBACK_SPOKEN.

Returns the string representation of a flag. For example, DEFAULT is represented by the string DEFAULT.

This method was deprecated in API level 16.
Use loadDescription(PackageManager).
Gets the non-localized description of the accessibility service.
Statically set from meta-data.
The accessibility service id.
Generated by the system.
The service ResolveInfo.

The localized description of the accessibility service.
Statically set from meta-data.
Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:
getClass().getName() + '@' + Integer.toHexString(hashCode())
See Writing a useful toString method if you intend implementing your own toString method.
