Is this the full error message? Looks like the second part is missing.

This is the relevant error: Caused by: java.lang.RuntimeException: Object should first be initialized (WebViewExtras).

You need to initialize WebViewExtras.

 

[hitesh.k]

Webextra.Initialize("webview1")

It rases warning msg and compile error warning; types do not match

 

[Erel]

I don't remember all APIs but you probably need to pass the actual WebView as the parameter.

 

[hitesh.k]

webview1 is default web view added from designer if i can get some working example of webviewextra
lib it would be helpful

 

[hitesh.k]

ok partial problem solved by using advwebview lib now popups is visible one of the popup is a WhatsApp icon which open WhatsApp
when pressed which is working in browsers but in advwebview open a err msg url scheme not found any idea ?

 

[hitesh.k]

Private Sub AdvancedWebView1_onPageError(errorCode As Int, description As String, failingUrl As String)
    
    If failingUrl.Contains("whatsapp")Then
        Dim Intent1 As Intent
        
        Intent1.Initialize(Intent1.ACTION_VIEW, failingUrl)
        StartActivity(Intent1)

    End If
    
        
    
    End Sub

made this for open whatsapp
