Activity still added to the stack after Activity.Finish

[tamadon]

I call an activity (say Activity A) from the main activity. In Activity A, I initialize some objects from a class. The object is referenced on the Process Globals of Activity A so that I can access the object from other Activity.

I click the Next button to exit Activity A and call Activity.Finish to remove it from the Activity stack. Then move to another activity(say B).

Activity B will refer the objects initialized from Activity A.

However when I click on the back button while on Activity B, Activity A is still being displayed even though I have called Activity.Finish. I thought I should go straight to the main activity?

Main <-> Activity A (Activity.Finish called when exiting) <-> Activity B

Does referring the objects from Activity A recreate the activity?

What version of b4a are you using?

I don't know what's causing this, but you can always trap the 'back' button and send your app to the activity you choose.

No.

I created a simple test and it is working as expected. Try to reproduce it with a small project.

Are you using CallSubDelayed to call subs in activity A? I think that could possibly cause that behavior but I would guess that activity A would reappear before closing activity B. Just an idea to run by you while troubleshooting the problem.

I've done that actually but it ignores the instruction and still display Activity A

So in Activity B I have this but it doesn't work.

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'Return True to consume the event
   If KeyCode = KeyCodes.KEYCODE_BACK Then      
      Activity.Finish
      SPClock.Pause(SPPClock)
      StartActivity(Main)
      storyClass.SetAnimation("zoom_enter", "zoom_exit")
      Return True
   End If
End Sub

OK I will try to do that Erel.

Was thinking of doing that initially but I decided to refer the objects via Activity A's Process_Globals instead to avoid re-creating Activity A

Ahh.. I should have checked the log closer. I appears that it does go straight to the main activity... but there's a flag in the Activity Resume that mistakenly calls Activity A again :sign0161:

Anyway thanks everyone for the response
