How to implement showing webview after content is fully loaded?
The problem is the following - there is a link on which advertising is given (html content), at the beginning there are several redirects on the link, and at the end html content is given (maybe a page, maybe a banner or video) - if you just open a webview, then it takes a very long time on a slow connection void can be displayed, is it possible to somehow make a prefetch and show it only after the data is fully loaded?
