Android Question get the current page ( current page is showing to user)

alimanam3386 · Jul 30, 2020

I am using B4XPages in my current app, my question is how we can get the current page that is showing to user ( current page ) ???
in b4a we have isPause function and that was very useful.

I am using firebase messaging, I have this code in Main module :

B4X:

Private Sub Application_RemoteNotification (Message As Map, CompletionHandler As CompletionHandler)
   if PageChat_Was_Current_Page then ' (if PageChat is current page then show this message in this page )
        ' show message in PageChat
   else
     log(Message)
   end if
   CompletionHandler.Complete
End Sub

B4X:

    Dim info As B4XPageInfo = B4XPages.GetManager.FindPIFromB4XPage(Me)
    Log(info)

If i do interpreted it right it is a mistake to add any code to the Main Module when using B4XPages. It should be added to B4XMainpage.

See this Post:

B4XTable1 and B4XPage

Hi how can I access "Private B4XTable1 As B4XTable" in Main from B4XPage = ( Main.B4XTable1 ) Thanks

Right but I use Firebase messaging and I think we should implement that in Main module if I am in mistake please correct that.

If you must modify Main then try

B4X:

Dim topinfo as B4XPageInfo = B4XPages.GetManager.GetTopPage
' topinfo now is a B4XPageInfo with data relating to the top page

FirebaseMessaging has nothing to do with the main module.

Don't call B4XPages from FirebaseMessaging service as it runs before B4XPages was initialized.

So how can I access pages when a message arrives? How can I know which page is on top to show it ?

B4X:

If B4XPages.Delegate.IsInitialized Then
    Dim TopPage As String = B4XPages.GetManager.GetTopPage.Id
Else
 Log("no page")
End If
