AS3 Stage changing by itself, how is it possible?

Question

I'm developing an Air App for Android. It was going very well when it occurred. Let me explain a bit more: I run the app, everything is ok: the stageWidth is 800 as I've defined before. (I know that is impossible to set stageWidth at runtime and that stageWidth and stageHeight is read only. I press back/home button and my application loses focus normally, but when I open application again either by recent list apps or menu apps, the stageWidth changes by itself to 1794. I really don't know why this number and not even do not know how is possible alter stageWidth.

Capabilities.screenResolutionX and Capabilities.screenResolutionY are what you should use for screen width and height on apps. Note: they don't change with rotation - they'll stay the same when screen rotates, so your code will look something like this:

if (bStagePortrait) {
    iScreenWidth = Capabilities.screenResolutionX;
    iScreenHeight = Capabilities.screenResolutionY;
} else {
    iScreenWidth = Capabilities.screenResolutionY;
    iScreenHeight = Capabilities.screenResolutionX;
}

Use this code in app to keep app from stretching and in left corner:

stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;

If you make those changes, you should start seeing good numbers.
