[DonManfred]

does you code match the if? I mean put a log into it. dont DO anything. just LOG to see what happens....

Sub WebView1_OverrideUrl (Url As String) As Boolean
   If Url.indexof(".pdf")>0 Or Url.IndexOf(".doc")>0 Or Url.IndexOf(".docx")>0 Or Url.IndexOf(".zip")>0 Then
        log("Document on "&Url&" found")
        'Dim p As PhoneIntents
        'StartActivity(p.OpenBrowser(Url))
        Return True
     Else
        Return False
   End If
End Sub

Do you get the log-output?

Your eventname is WRONG!

You set webpage in designer as eventname for the webview. Not Webview1

Sub webpage_PageFinished (Url As String)
   Log($"PageFinished(${Url})"$)   
End Sub
Sub webpage_OverrideUrl (Url As String) As Boolean
   Log("Got URL: "&Url)
   Return True
     If Url.indexof(".pdf")>0 Or Url.IndexOf(".doc")>0 Or Url.IndexOf(".docx")>0 Or Url.IndexOf(".zip")>0 Then
        Log("Document on "&Url&" found")
        'Dim p As PhoneIntents
        'StartActivity(p.OpenBrowser(Url))
        Return True
     Else
        Return False
   End If
End Sub

Thanks and sorry for the mistake. this my 1st time use webview. after change with your code. my log output show this.

** Activity (main) Pause, UserClosed = true **
** Service (starter) Create **
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
PageFinished(https://apdm.moe.gov.my/)
Got URL: https://apdm.moe.gov.my/panduan/dokumen_MBK.zip

So you get the url... But your if does not match as the second log entry is not shown.
Search the error.

To download the zip you need to use httputils and download the zip by yourself and in JobDone you need to save the result to a file giving it the right filename.
