I have a simple webview that should load https website , i got white page & website not loading!

It is impossible to say anything without a small example!

Where's your example code gone from yesterday @HAH?

I tried it and it was blank, other sites worked in webview but that one site didn't, and yes that site works perfect in desktop browsers.

this is the example he uploaded yesterday.

You should use File - Export as zip when uploading projects.

Check the unfiltered logs:
Failed to validate the certificate chain, error: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

This error means that Android doesn't recognize this site certificate.

Solution that ignores all certificates, based on WebViewExtras2:

Sub Globals
   Private WebView1 As WebView
   Dim wve As WebViewExtras
End Sub

Sub Activity_Create(FirstTime As Boolean)
   'Do not forget to load the layout file created with the visual designer. For example:
   Activity.LoadLayout("Layout1")
   
   Dim c As DefaultWebViewClient
   c.Initialize("client")
   wve.Initialize(WebView1)
   wve.SetWebViewClient(c)   
   WebView1.LoadUrl("http://yesmallz.com/")
End Sub

Sub client_ReceivedSslError(SslErrorHandler1 As SslErrorHandler, SslError1 As SslError)
   Log(SslError1)
   SslErrorHandler1.Proceed
End Sub

Sub client_ReceivedSslError(SslErrorHandler1 As SslErrorHandler, SslError1 As SslError)
Log(SslError1)
SslErrorHandler1.Proceed
End Sub

Excellent, worked fine

Mr. @Erel ; I don't find this event client_ReceivedSslError in b4x forum (not mentioned before)!!! How you create it from nothing?

How you create it from nothing?

Lean the language.

write SUB + space, press TAB, write for exymple "webview"

I only know an german thread from Klaus. but i´m sure there is a similar one in english somewhere...

Also note that this is a feature since years and something your should know.

Please watch the following video, about half way through Erel talks about 'Event Sub Signatures' and how to find/create them once you have selected the correct library.

This information is also available in the PDF guide by Klaus, you can download the manuals from the forum, search for ''ide tips'.

Enjoy...
