CustomWebView : An extended form of Web Viewer

Did you try double tapping?

yes

Can someone please answer this?

And more importantly this

Hi, I’m using CustomWebView extension. When a webpage fails to load (like no internet), it shows the default message:

"Web page not available… net::ERR_..."

Instead, I want it to show a custom error page with a ā€œReloadā€ button, handled inside the CustomWebView extension itself. I tested an extension SwipeRefresh to pull to refresh, but unfortunately that was no work for me.

Is there a way to detect load failure and display a custom HTML with a reload option?

Thanks!

Have a look at the blocks, specially event (yellow) ones. Maybe you'll find block for handling errors.
