Android Question Notify with msgbox or simil

[netsistemas]

I use FirebaseMessaging for recibe message in app

when main opens, the user loses the window they are in. I think I cannot launch a MSGBOX from the FIREBASENOTIFY service

Sub NotificacionLocal(Title As String, Body As String, Tipo As String )
    Dim  NewNotificacion As NB6
Dim IdNotificacion As Int
    Private smiley As Bitmap
    
    
    Try

        Log("NotificacionLocal a")
        smiley = LoadBitmapResize(File.DirAssets, "f.ico", 24dip, 24dip, False)
        'DEFAULT - PRIORITY
        NewNotificacion.Initialize( "default",  Application.LabelName, "HIGH").SmallIcon(smiley)
        IdNotificacion = 10
        NewNotificacion.AddButtonAction(smiley, Tipo & " Entendido", ServicioNotificacion, "2")
        Dim cs As CSBuilder
        If Tipo.ToUpperCase  = "UPLOAD" Then
            
            NewNotificacion.AddButtonAction(Null, cs.Initialize.Color(Colors.Red).Bold.Append( "Descarga").PopAll, ServicioNotificacion, "1")
        else if Tipo.ToLowerCase ="VERSION" Then
            
        Else if Tipo.ToUpperCase = "MSG" Then
            'Msgbox(Body,Title)
            CallSubDelayed3(Main,"Msg",Body,Title)
            'Msgbox2Async(Body,Title,"ACEPTAR","","",modGeneral.BM,False)   
        else if Tipo.ToUpperCase ="GPS" Then
            CN.NotificarLatLon
        End If
        NewNotificacion.DeleteAction(ServicioNotificacion, "delete action")
        NewNotificacion.AutoCancel(True)
        
        Noti = NewNotificacion.Build(Title, Body, "tag",  Main)

        Noti.Notify(IdNotificacion)
            Log("NotificacionLocal Z")
            
    Catch
        Log(LastException)
    End Try
End Sub

and in main:

private Sub Msg(T1 As String, T2 As String)

    Msgbox2Async(T1,T2,"ACEPTAR","","",modGeneral.BM,False)
End Sub

You cannot show a dialog from a service. You can show a high importance notification and depending on the device settings it might show as a popup.

If there is a foreground activity when the notification arrives then you can call a method with CallSub (or better using B4XPages) and show whatever you like.

 

[netsistemas]

it is posible know the activity active (in a foreground )
And include in ALL activitis the same code, (sub showmsgbox ) and callsub to the activity.active this method?

No automatic way. You can check with IsPaused(ActivityName) the state of each activity.

And include in ALL activitis the same code, (sub showmsgbox ) and callsub to the activity.active this method?

Never duplicate code. Implement whatever you need in a class and create an instance of this class in each of the activities.
