OmPrakash Muppirala commented on FLEX-33371:
--------------------------------------------
This particular comment on the bugbase could be a possible workaround:
"For workaround this issue, you can put <uses-sdk
android:targetSdkVersion="11"/> in <manifest> inside of the app.xml to avoid
invoke Event trigger by surface Change. "
> On Android, changing orientation fires Event.DEACTIVATE and
> FlexEvent.VIEW_DEACTIVATE events

> Key: FLEX-33371
> URL: https://issues.apache.org/jira/browse/FLEX-33371
> Project: Apache Flex
> 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
> Reporter: Erik Thomas
> Priority: Critical
> Fix For: Adobe Flex SDK 4.6 (Release)
>
> Attachments: AndroidDeactivateOnOrientationChangeDefect.zip
>
>
> 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.
