Flex 4.6 Mobile- soft keyboard and andorid back button

Question

Forgive me as I posted this question in another thread but it doesn't seem to be getting much attention.
When using Flex 4.6 on Android I've noticed an undesired behavior related to the soft keyboard.
When the soft keyboard is open and you press the hardware back button two things happen:
First, the keyboard closes.
Then, if you're on a secondary view you get a pop view or if you're on the home view the app closes.
I've been trying to solve this by overriding the hardware back button but have yet to come up with anything that works. It seems most of the posted solutions are for older versions of Flex and don't seem to work in 4.6
Both of my phones I'm testing this on are HTC's incase this is hardware specific.

Hi GEG_man and frank,
try to do as shown in the code below works for me, I tried to simplify the code to SoftKeyboard to prevent the application exits on pressing the back button:
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        title="Test SoftKeyBoard" viewActivate="view1_viewActivateHandler(event)" backKeyPressed="backKeyPressedHandler(event)"
        destructionPolicy="never">
    <fx:Script>
        <![CDATA[
            import mx.events.FlexEvent;
            import spark.events.IndexChangeEvent;
            import spark.events.TextOperationEvent;
            import spark.events.ViewNavigatorEvent;
            private var focusInOut:Boolean = false;
            protected function view1_viewActivateHandler(event:ViewNavigatorEvent):void
                message.text = data.description;
                message.setFocus();
            protected function backKeyPressedHandler( event:FlexEvent ):void {
                //trace("Trigger: "+event.type);
                //trace("USER_TRIGGERED: "+SoftKeyboardTrigger.USER_TRIGGERED.length);
                if(SoftKeyboardTrigger.USER_TRIGGERED.length == 13 && focusInOut==true){
                    event.preventDefault();
                    stage.focus = stage;
                } else {
                     stage.focus = null;
            protected function recipient_softKeyboardActivateHandler(event:SoftKeyboardEvent):void
                trace("Activate: "+event.type);
                event.preventDefault();
                stage.focus = null;
                setFocus()==true;               
            protected function recipient_softKeyboardDeactivateHandler(event:SoftKeyboardEvent):void
                //trace("Deactivate: "+event.type);
                event.preventDefault();
                stage.focus = stage;
                setFocus()==false;
        ]]>
    </fx:Script>
    <s:TextArea id="message" width="100%" height="300" change="message_changeHandler(event)" text="{data.description}"
                softKeyboardActivate="recipient_softKeyboardActivateHandler(event)" softKeyboardDeactivate="recipient_softKeyboardDeactivateHandler(event)"
                focusIn="focusInOut=true" focusOut="focusInOut=false"/>
</s:View>
I've tested it on Galaxy S3 and LG P990 and Air 3.4/3,5/3.6.
enjoy
