Native Extension control for long list Demo. In that application we have a test page where user can open native long list control and select item from list. When user select item - application return to web view and show selected info. We have a list with 10000 items. Each item contain image and 3 text field. data for items requested from native control by demand. Ruby control prepare data in XML/JSON format. I add 10 different images to application , but now each item load image separately without any caching - in this case application can have unique image for each item without any perfomance losses. As I say before - native control works without any visual pause. Native extension prepared for iOS and Android.
