I wonder how do I customize the default Webview error page. I tried hundreds of ways and none worked. I have some pages using iframe, when the user runs out of internet or if there is a related issue, I want to prevent this default Webview page from being displayed by exposing the iframe URL.
This link below has exactly what I want.
It can be any kind of solution as long as it prevents Webview from showing the URL that generated the error.
I thank you immensely for any help.
