    If activity1.a1=0 Then
        MsgboxAsync("xxx", "info")

    Else If activity1.a1=1 Then

Dim a1 As Int

Private Sub Amir_onItemClick (Parent As Panel,Position As Int)
    a1=Position
  
    B4XPages.ShowPage("activity2")
  
End Sub

activity2: 
Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    'load the layout to Root
    Root.LoadLayout("layot1")
  
    If B4XPages.MainPage.activity1.a1=0 Then
         MsgboxAsync("xxx", "info")
      
    Else If B4XPages.MainPage.activity1.a1=1 Then

What is this?
It would be easier to help you, at least for me, if you posted a small project showing the problem.
Just with code snippets it is difficult to help.

I added a small project. The project I want to convert is test1.

You should create the B4XPage_Appear event routine and move NetWork there.
As the comment says, B4XPage_Created is called only once when the page is created.
B4X: 
'This event will be called once, before the page becomes visible.
Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    'load the layout to Root
    
'    Network
End Sub

Private Sub B4XPage_Appear
    Network
End Sub

To generate a zip file for a B4XPages project you should use this line on top of the code in B4XMainPage.


I had to comment line #2 to make the program run because of the missing Shared Files folder.
