    Dim p As PhoneIntents
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("1")
    Dim client As JavaObject
    Dim jo As JavaObject = WebView1
    client.InitializeNewInstance(Application.PackageName & ".main$MyChromeClient",Null)
    jo.RunMethod("setWebChromeClient", Array(client))
    WebView1.LoadUrl("https://SomeUrl.ZzZ")
End Sub

You should tell us where this code come from. I guess that you didn't add the inline Java code.
