Android Question Freeze on real device only

[epiCode]

I have this strange problem where the program freezes on a touch event while executing simple setlayoutanimated animations:
however after trying to debug this is what I have observed
1. It happens only on real devices and not on emulator (emulator android version 7.1)
2. Program passes over the same code multiple times but does not freeze first few times.
4. Does not hang in debug mode
3. There is no error or crash. It just causes the running application to go into "App is not responding - close - wait".

I tried putting multiple log statements to check where exactly does the code stop responding, and found that it pauses on the beginning of a "If then" statement which is as simple as if moveright then (moveright is boolean variable)

I would appreciate if experts here can guide me on how else can it be debugged or what else can be done to find out the cause of freezing.

    inframe.Visible            = True

    If  moveright Then    ' <- this is the line at which freeze occurs
            inframe.SetLayout(-(100%x) ,inframe.Top,inframe.Width,inframe.Height)
            outframe.SetLayoutAnimated(500,100%x,outframe.Top,outframe.Width,outframe.Height)
            inframe.SetLayoutAnimated(500, 0,inframe.Top,inframe.Width,inframe.Height)

I guess that your code enters an endless loop. Maybe the touch event is raised indefinitely.

There isn't enough information here to say what causes it. Wild guess: [B4X] Resumable subs and the index pattern

I believe that SetLayoutAnimated does not wait for the animation to complete before returning control back to the app.
I believe that you will have to put some sleeps in the code after each animation to allow the animation to complete before performing the next one.

for example the following code move the panel off the screen and then hides and removes its contents

private Sub CloseOverlay As ResumableSub
    pnlOverlay.GetView(0).SetLayoutAnimated(200,0,pnlOverlay.Height,pnlOverlay.Width,pnlmenuoverlay.Height)
    Sleep(200)
    pnlOverlay.Visible = False
    pnlOverlay.RemoveAllViews
    Return Null
End Sub

Also remember that the position are relative to the views parent not to the screen, so using 100%x may not be appropriate.
