Remarks
Object responsible to ensuring that a View
is prepared to meet a synchronous request for accessibility data.
Because accessibility requests arrive to View
s synchronously on the UI thread, a View that requires information from other processes can struggle to meet those requests. Registering an instance of this class with AccessibilityManager
allows a View to be notified when a request is about to be made, and to asynchronously inform the accessibility system when it is ready to meet the request.
<strong>Note:</strong> This class should only be needed in exceptional situations where a View
cannot otherwise synchronously meet the request for accessibility data.
