*** ** * ** ***
This class represents accessibility events that are sent by the system when something notable happens in the user interface. For example, when a `https://developer.android.com/reference/android/widget/Button` is clicked, a `https://developer.android.com/reference/android/view/View` is focused, etc.
An accessibility event is fired by an individual view which populates the event with data for its state and requests from its parent to send the event to interested parties. The parent can optionally modify or even block the event based on its broader understanding of the user interface's context.
The main purpose of an accessibility event is to communicate changes in the UI to an `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService`. If needed, the service may then inspect the user interface by examining the View hierarchy through the event's `https://developer.android.com/reference/android/view/accessibility/AccessibilityRecord#getSource()`, as represented by a tree of `https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo`s (snapshot of a View state) which can be used for exploring the window content. Note that the privilege for accessing an event's source, thus the window content, has to be explicitly requested. For more details refer to `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService`. If an accessibility service has not requested to retrieve the window content the event will not contain reference to its source. **Note:** for events of type `https://developer.android.com/reference/android/view/accessibility/AccessibilityEvent#TYPE_NOTIFICATION_STATE_CHANGED` the source is never available, and Views that set `https://developer.android.com/reference/android/view/View#isAccessibilityDataSensitive()` may not populate all event properties on events sent from higher up in the view hierarchy.
This class represents various semantically different accessibility event types. Each event type has an associated set of related properties. In other words, each event type is characterized via a subset of the properties exposed by this class. For each event type there is a corresponding constant defined in this class. Follows a specification of the event types and their associated properties:

Added in [API level 14](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final int TYPE_VIEW_SCROLLED

Represents the event of scrolling a view. This event type is generally not sent directly. In the View system, this is sent in `https://developer.android.com/reference/android/view/View#onScrollChanged(int,%20int,%20int,%20int)`
In addition to the source and package name, the event should populate scroll-specific properties like `https://developer.android.com/reference/android/view/accessibility/AccessibilityRecord#setScrollDeltaX(int)`, `https://developer.android.com/reference/android/view/accessibility/AccessibilityRecord#setScrollDeltaY(int)`, `https://developer.android.com/reference/android/view/accessibility/AccessibilityRecord#setMaxScrollX(int)`, and `https://developer.android.com/reference/android/view/accessibility/AccessibilityRecord#setMaxScrollY(int)`.
Services are encouraged to rely on the source to query UI state over AccessibilityEvents properties. For example, to check after a scroll if the bottom of the scrolling UI element has been reached, check if the source node is scrollable and has the `https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#ACTION_SCROLL_BACKWARD` action but not the `https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#ACTION_SCROLL_FORWARD` action.

Details about the change are available from `https://developer.android.com/reference/android/view/accessibility/AccessibilityEvent#getContentChangeTypes()`.
Do not use this to get an accessibility service to make non-pane announcements. Instead, follow the practices described in `https://developer.android.com/reference/android/view/View#announceForAccessibility(java.lang.CharSequence)`. **Note:** this does not suggest calling announceForAccessibility(), but using the suggestions listed in its documentation.
