Android Question Webview Error

[DawningTruth]

I have a webview setup. When I click on a url within the webview it crashes the app. Any suggestions?

Here is the error I get:

Error occurred on line: 357 (ViewSite)

Here is the relevant code:

'Initialisation Code
    Private webViewExtras_ As WebViewExtras

'....

Sub wbv_WebContent_OverrideUrl (Url As String) As Boolean
     
    Private thisWebView As WebView = Sender

    Try
        'Setup WebView Extras
        webViewExtras_.Initialize(thisWebView) '## Get error here
       
    Catch
        Log(LastException)
        Return
    End Try

It's incorrect to initialize webview extras inside that subroutine.

Move that line to the the area where you do one-time initialization of your other views.

it has this line in it:

Private thisWebView As WebView = Sender

Which changes the way it works
