Android Question B4XDrawer error object should first be initialized

[angel_]

I've included the last B4XDrawer library

[B4X] B4XPages + B4XDrawer

B4XDrawer v1.53 adds support for B4J. This is a good opportunity to create a B4XPages example using B4XDrawer. It does require some configuration so pay attention. The example is based on the three pages example...

www.b4x.com

The example works smoothly, but in my project I have this error only en B4A (in B4i and B4J it works well):

** Activity (main) Resume **
Error occurred on line: 15 (B4XPages)
java.lang.RuntimeException: Object should first be initialized (JavaObject).

In this line:

Private Sub B4XPage_Appear
    #if B4A
    Sleep(0)
    B4XPages.GetManager.ActionBar.RunMethod("setDisplayHomeAsUpEnabled", Array(True))   '<< HERE
    Dim bd As BitmapDrawable
    bd.Initialize(HamburgerIcon)
    B4XPages.GetManager.ActionBar.RunMethod("setHomeAsUpIndicator", Array(bd))
    #End If
End Sub

I have tried to reproduce the problem in a small project but it does not fail

Make sure that #IncludeTitle attribute is set to true.

Make sure that #IncludeTitle attribute is set to true.

I changed it but the same error happens

Hard to say. Carefully compare your project to the example project.

The problem was in the AppCompact library and everything related to it, such as: Manifest, NightMode, etc.
