Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'Public variables can be accessed from all modules.
    Public App As Application
    Public NavControl As NavigationController
    Private Page1 As Page
    Private spnday As Picker
End Sub

B4X: 
Private Sub Application_Start (Nav As NavigationController)
    NavControl = Nav
    Page1.Initialize("Page1")
    Page1.Title = "Page 1"
    Page1.RootPanel.Color = Colors.White
    Page1.RootPanel.LoadLayout("thu") 'layout thu is mine, you can use designer and save with other name
    NavControl.ShowPage(Page1)
    NavControl.ToolBarVisible=False
    NavControl.NavigationBarVisible=False
Dim daylist As List
daylist.Initialize
For i=1 To 31
daylist.Add(i)
Next
spnday.SetItems(0,daylist)
End Sub
