--------------------------------------------

Ah, then this seems to be an AIR runtime issue.  You might want to get this on Adobe's radar.
 I looked at the ViewNavigatorApplication class and I dont see anything fishy going on there.
 

I see some other folks having this and similar issues as well:

A very similar bug that was fixed recently in the latest AIR runtime:

Which version of AIR are you on?

>          Issue Type: Bug
>          Components: Mobile: MobileApplication
>    Affects Versions: Adobe Flex SDK 4.6 (Release)
>         Environment: Samsung Galaxy Express and Galaxy S III Android Phones, FlashBuilder
4.7 Premium on Windows 7, debugging through USB as well as deployed release builds, iPhone
and iPad, but the problem doesn't exist on iOS devices, only Android

> Orientation changes on Android devices always fire the following events in this order:
> ViewNavigatorEvent.VIEW_DEACTIVATE
> Event.DEACTIVATE
> StageOrientationEvent.ORIENTATION_CHANGE
> The first two events are a defect. They must not fire simply because the user changed
the orientation of the phone.
> The result of this defect is that we cannot do two very important things:
> 1. Use view state changes to hide/show layouts, using includeIn property on containers
and components. On Android, components that are not included for a given state are destroyed
yet they have state we want to maintain which is why we don't change Views.
> 2. We cannot know when the user navigates away from our application, for example to press
the Home key. We have certain cleanup we must do in our complex connected app that streams
FMS data, etc., and cannot keep sockets open for hours or days.
> On iOS, this is not a problem. Only Android has this bug and it's blocking us from releasing
our product on Android. iOS does not have this defect.
