Remarks

Adds extra data to an AccessibilityNodeInfo based on an explicit request for the additional data.

This method only needs to be implemented if the View offers to provide additional data.

The default implementation behaves as View#addExtraDataToAccessibilityNodeInfo(AccessibilityNodeInfo, String, Bundle) for the case where no accessibility delegate is set. </p>

@param host The View hosting the delegate. Never {@code null.
