AccessibilityDelegateCompat

open class AccessibilityDelegateCompat(source)

(SESL Variant) Helper for accessing AccessibilityDelegate.

Note: On platform versions prior to API 23, delegate methods on views in the android.widget.* package are called before host methods. This prevents certain properties such as class name from being modified by overriding onInitializeAccessibilityNodeInfo, as any changes will be overwritten by the host class.

Starting in API 23, delegate methods are called after host methods, which all properties to be modified without being overwritten by the host class.
