This is a part of my Code Snippets collection, needed in many projects.
It is useful to have at least one global class in the project for all the things, you want to access and to call from every page and every class. I use an object "cG" from a class "xGlobalClass".
In menu "Project / Add New Module / Class Module / Standard Class" give the name "xGlobalClass" and choose "Add module to parent folder".
I also use an helper module "mH" ("Add New Module / Code Module") for all global methods that only take and return parameters without saving any value. From here I also like to access the GlobalClass, because, for example, "mH.GetVersion" is shorter than "main.cG.i_MyVersion.
Some things needs OS Specific code

B4X:
Sub Class_Globals
Public s_MyGlobalString as String
Public i_MyVersion as Int = 12
End Sub
'Initializes the object. You can add parameters to this method if needed.
Public Sub Initialize
End Sub
Public Sub MyGlobalMethod
End Sub
Define the GlobalClass cG in Main module:
Sub Process_Globals
Public ActionBarHomeClicked As Boolean
Public cG As xGlobalClass 'global
End Sub
Initialize it in B4XMainPage:
'This event will be called once, before the page becomes visible.
Private Sub B4XPage_Created (Root1 As B4XView)
Main.cG.Initialize
End SubI also use an helper module "mH" ("Add New Module / Code Module") for all global methods that only take and return parameters without saving any value. From here I also like to access the GlobalClass, because, for example, "mH.GetVersion" is shorter than "main.cG.i_MyVersion.
Often needed values from GlobalClass in an helper- CodeModule like "mH":
Public Sub GetVersion() as Int
Return Main.cG.sMyVersion
End SubSome things needs OS Specific code
