Android Question Process_Globals Variables

[Baltazar]

Hi everyone,
How big is the amount of data we can temporarily save inside Process_Globals block ? Is there a recommended amount an application should keep there? For example , I need to save around 100kB worth of variable values (when the activity gets paused) so that I can replicate my screen later on .Is this value reasonable? Or can I temporarily save there say, around 200kB or even more without worrying about system crash? In conventional OS, this would not be a problem because the OS's virtual memory manager will cache it in the secondary storage.

I think that variables occupy RAM memory, even if they are declared in the process_global.

The difference is only their "visibility" (scope).

Thanks LucaMs . I have expanded the question.

And here's a follow up : I have created a class but it seems , it cannot access the Process_Globals variables although I don't get any warning or error from the IDE. The test consists of a button created in a class and viewed in the main activity. The activity has a timer that ticks every 500ms and monitors a boolean variable in the Process_Globals and responds accordingly when the variable is true. Here, when I click the button nothing happens but I monitored that the timer is ticking. Here's the code:

Main Module:

Sub Process_Globals
    Dim monitor As Boolean
    Dim tmr As Timer

End Sub
Sub Globals
    Dim bClass As myclass
End Sub
Sub Activity_Create(FirstTime As Boolean)
   tmr.Initialize("tmr",500)
   tmr.Enabled = True
   bClass.Initialize("")
   Activity.AddView(bClass.View,40%x,40%y,20%x,20%y)
End Sub

Sub tmr_tick
   Log("Tick!")  ' it is indeed ticking!

   If monitor Then     ' this section is not executed
   Log("Caught")
   ToastMessageShow("Clicked",False)
   monitor = False
   End If

End Sub

My Class :

Sub Class_Globals
    Private btn As Button
End Sub


Public Sub Initialize(objName As String)

  btn.Initialize("btn")
End Sub

Sub getView As View
   Return btn
End Sub

Sub btn_click
   monitor = True       'let's change the state of a var in Process_Globals
End Sub

You'll need to prefix the variables in your main acctivity's Process_Globals with Main.whatever to access them from another module.

Quick reply from the community ,as usual.
Muchas Gracias! HotShoe . I suppose the same scope resolution applies to classes? Oops, I realized, the Private and Public directives would take care of it.

 

[LucaMs]

Instead of using a timer in the Main, put there for example:

Public Sub Monitor_Click
end Sub

and in your Class:

Sub btn_click
    CallSubDelayed(Main, "Monitor_Click")
End Sub

(So you've basically created an event)
