This is the easiest one, than debugging errror code i think :smiling_face:

If you still needed to use the error from the Custom WebView, you can use the error code+contains but this may triggered either the device got internet access

A smartphone screen displays a 'Webpage not available' error message with an ERR_CONNECTION_ABORTED notification. (Captioned by AI)

Cant we block this "webpage not available"page. it should not show at all.
or
when it is triggered, custom error screen should show.

1983

Show what you have done using OnErrorOccurred event.

sir, i tried like this. when internet disconnected, it showed blank page. when i connected it using no data sim, it showed Webpage not available with err_connetion_aborted.

1986

Good, now tell me what error are you handling in the event?
Is it err_connetion_aborted ?

A simple search on google about android webview error codes will give you common error codes which you’ll need.

How to clear CustomWebView history stack when switching URLs on a single ID?

I am building an app using CustomWebView extension and I’m having trouble managing the browser history stack.

My app has a Home screen layout with multiple Card Views (e.g., Syllabus, Notifications). When clicked, each card sets a webviewer layout to visible and loads a specific URL using ID 1.

The Problem: When switching between these sections, the history stack from the previous URL remains active.

  1. User clicks Syllabus - opens Syllabus URL.
  2. User presses Back - hides webviewer layout, returns to Home layout.
  3. User clicks Notifications - opens Notifications URL.
  4. User presses Back - instead of returning to the Home layout, the webview navigates backward to the Syllabus page because it’s still in the history stack of id 1.

I have attached Current Blocks. Any guidance / block examples would be greatly appreciated. Thank you! @vknow360

You call GoBack before you clear the internal history ?

If you just want to go to the Home layout, why not just call that url ?

1990

Please guide me with the correct backpressed blocks.

1991

You may want to set/reset a url for the webviewer and clear the history?

1992

When backpressed, look for previous page, if no pages, clear web history and close. Thats what i want.

1993

Set a variable with your previous page url, then call that instead of relying on GoBack

1994

Hi dear,

Isn’t it enough to simply not use GoBack? :grin:

1995

There are more links inside the syllabus page.

1996

So you simply need to clear the History when you’re not in Syllabus.
I recommend following this guide that explains how to use virtual screens

you can implement it and use it to specify that if you’re not in Syllabus or others “screen”, it should clear the History
