HI, All

Sometimes there is error at this sub, if without delay the AppCompat activity is required to be closed.
Seems, the menu is not created yet or so.

When the menu creation starts ? How to control menu creation moment ?

I don't like

B4X: 
public boolean _onCreateOptionsMenu(android.view.Menu menu) {
    if (processBA.subExists("activity_createmenu")) {
        processBA.raiseEvent2(null, true, "activity_createmenu", false, new de.amberhome.objects.appcompat.ACMenuWrapper(menu));
        return true;
    }
    else
        return false;
}

Not sure, but raiseEvent looks like asynchronous operation. So, when event happens "menu" (theoretically) can be absent.
Probably, better to use something like this:
B4X: 
public boolean _onCreateOptionsMenu (android.view.Menu menu)
    { try { _activity_createmenu (new de.amberhome.objects.appcompat.ACMenuWrapper (menu)); return true; }
    catch (Exception e) { return false; } }

"Go and se a tutorial that DOES NOT solve the error" is not an answer.

This "suggestion" is ACTUALLY an option to solve the problem.

And another answer(Maybe not the best option), what I did it was just to enclose all the code with a TRY:

B4X: 
Sub Activity_CreateMenu(Menu As ACMenu)
Try
    'Your code to add items here
    ToolBar.InitMenuListener
Catch
    Log("Activity_CreateMenu Error")
End Try

End Sub
