Here is my B4a code:

Sub Activity_Resume
...
    If Not(Starter.manager.getBoolean("IsPrivacyPolicyAllowed")) Then
        CallSubDelayed(Me, "ShowPrivacyPolicy")
    End If
...
End Sub

Private Sub ShowPrivacyPolicy
    Dim dialog As CustomLayoutDialog

    Dim sf As Object = dialog.ShowAsync("", "OK", "", "",Null, False)
    Wait For (sf) Dialog_Ready (DialogPanel As Panel)
    DialogPanel.LoadLayout("frmprivacypolicy")
    
    'View beschriften
    wbvPrivacyPolicy.LoadHtml(File.GetText(File.DirAssets, Starter.Language.Value("Datenschutzfile")))
    cbxPrivacyPolicy.Text = Starter.Language.Value("PolicyAllowed")
    cbxPrivacyPolicy.Checked = Starter.manager.getBoolean("IsPrivacyPolicyAllowed")
    mAllg.SetCBDrawable2FromFont(cbxPrivacyPolicy, Chr(0xF096), Chr(0xF046), 24 / mAllg.Fontscale, Colors.DarkGray)

    mAllg.SetFontsizePanel(DialogPanel)

    Wait For (sf) Dialog_Result (Result As Int)
    Starter.manager.setBoolean("IsPrivacyPolicyAllowed", cbxPrivacyPolicy.Checked)
 
    If Not(cbxPrivacyPolicy.Checked) Then
        Activity.Finish
    End If
End Sub

wbvPrivacyPolicy.LoadHtml(File.GetText(File.DirAssets, Starter.Language.Value("Datenschutzfile")))

is wbvPrivacyPolicy a webview by any chance? is it the view referred to in the error message?

Hi @drgottjr ,
yes, wbvPrivacyPolicy is a webview and the error message refers to it.

If it is not due to a misspelling error (double-check that wbvPrivacyPolicy is defined with the same name in the 'frmprivacypolicy' layout),
I'd try to add a Sleep(400) after the LoadLayout just to see if it makes any difference.

where is it initialized?

Yes, I could try that, but then I should check whether this is the solution I want, and I can't, because I can't reproduce this error with my devices.
Normally the WebView should be available and initialized immediately after loading the layout, right?
Therefore I should know whether my code is actually correct or not.

Remove the webview, clean the project and then add a new webview back in.

Thank you!
I can try that.

Strange error. If there is only a single report of this error then ignore it.

The error has been reported 10 times by 2 users.

I would change my code now, what do you mean? Does it make sense?
Or should I not pay attention to it, as you have already suggested?

Private Sub ShowPrivacyPolicy
    Dim dialog As CustomLayoutDialog

    Dim sf As Object = dialog.ShowAsync("", "OK", "", "",Null, False)
    Wait For (sf) Dialog_Ready (DialogPanel As Panel)
    DialogPanel.LoadLayout("frmprivacypolicy")
    
    Dim pnl As Panel = DialogPanel.GetView(0)
    Dim wbv As WebView = pnl.GetView(0)
    Dim cbx As CheckBox = pnl.GetView(1)
    
    'View beschriften
    wbv.LoadHtml(File.GetText(File.DirAssets, Starter.Language.Value("Datenschutzfile")))
    cbx.Text = Starter.Language.Value("PolicyAllowed")
    cbx.Checked = Starter.manager.getBoolean("IsPrivacyPolicyAllowed")
    mAllg.SetCBDrawable2FromFont(cbx, Chr(0xF096), Chr(0xF046), 24 / mAllg.Fontscale, Colors.DarkGray)

'    wbvPrivacyPolicy.LoadHtml(File.GetText(File.DirAssets, Starter.Language.Value("Datenschutzfile")))
'    cbxPrivacyPolicy.Text = Starter.Language.Value("PolicyAllowed")
'    cbxPrivacyPolicy.Checked = Starter.manager.getBoolean("IsPrivacyPolicyAllowed")
'    mAllg.SetCBDrawable2FromFont(cbxPrivacyPolicy, Chr(0xF096), Chr(0xF046), 24 / mAllg.Fontscale, Colors.DarkGray)

    mAllg.SetFontsizePanel(DialogPanel)

    Wait For (sf) Dialog_Result (Result As Int)
    Starter.manager.setBoolean("IsPrivacyPolicyAllowed", cbx.Checked)
 
    If Not(cbx.Checked) Then
        Activity.Finish
    End If
End Sub

Better to use B4XDialog.
The error happens while the layout is loaded. It looks like it failed to create WebView for some reason.

 

[Peter Simpson]

I tate it that your privacy policy layout has a webview inside of it, if so try adding Sleep(0) after loading the layout.

Thank you!
I will try one of these 2 suggestions.

If it helps anyone, I had the same problem (Object should first be initialized (WebView).).
I realized that I had uninstalled chrome from my device.
After I reinstalled it, the problem was solved.

Regards

 

[drgottjr]

you'll be pleased to know that when you upgrade to android 10, you can, once again, remove chrome. until then, chrome controls webview, so you need it. as you discovered.

 

[Nando]

Thank you for the information drgottjr.

This morning the same problem came back and I had to do this... "Launch Play Store, start update of Android System Webview".
