Android Code Snippet Referring back to properties and methods of an instance of a Class

In part because I have lots of time on my hands.
But also I was surprised at what I found. Probably lots of you won't be.

I am working on a multi-platform project (B4A and B4J).
As recommended, I made my actual App an single instance of a Class.
That worked fine until I needed to instantiate another helper Class.
How to reference back to the original App instance's properties and methods?

CallSub was an option for methods, but what about properties (in B4A they can't be Process_Globals)?
See below, the magic is in casting the passed down "Me" to the original Class.
It works in both B4A and B4J.

Sub Process_Globals
    Public aNumber As Int = 999
End Sub

Sub Globals
    Public theProgram As App
End Sub

Sub Activity_Create(FirstTime As Boolean)        'ignore
    theProgram.Initialize
End Sub

'This is a class module App - but only one instance will created in Main
Sub Class_Globals
    Public myName As String = "William"
End Sub

Public Sub Initialize
    Log("Referring back to Main " & Main.aNumber)
    Main.aNumber = Main.aNumber + 1
    
    'Initiate an instance of Utilities Class
    Dim AUX As Utilities
    AUX.Initialize(Me)
    AUX.LogUtility
End Sub

Sub AppLog
    Log("AppLog in instance of App Class")
End Sub

'This is the Utilities Class

Sub Class_Globals
    Dim theApp As App
End Sub

Public Sub Initialize (AppInstance As Object)
    're-cast this object as class type App - here is the magic of this snippet
    theApp = AppInstance
End Sub   

Public Sub LogUtility
    'can refer to properties and methods defined in App class
    Log(theApp.myName)
    theApp.AppLog
    
    'can also refer to Process_Global variable in Main
    Log(Main.aNumber)
End Sub
