Question

Hi I am trying to the get my andoid app to show up full screen. But this doesnt work.
My stage is 480x800
And this is the code that I attempted to use:
package
          import flash.display.MovieClip;
          import com.greensock.*;
          import com.greensock.easing.*;
          import flash.events.MouseEvent;
          import flash.system.Capabilities;
          import flash.display.StageDisplayState;
          import flash.display.StageScaleMode;
          import flash.display.StageAlign;
          public class mainclass extends MovieClip
                    private var holder:holder_mc = new holder_mc  ;
                    private var btn:BTN = new BTN  ;
                    private var side1:side_mc = new side_mc  ;
                    private var side2:side_mc = new side_mc  ;
                    public function mainclass()
                              super();
                              stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;
                              stage.showDefaultContextMenu = false;
                              stage.scaleMode = StageScaleMode.NO_SCALE;
                              stage.align = StageAlign.TOP_LEFT;
                              holder.width = Capabilities.screenResolutionX;
                              holder.height = Capabilities.screenResolutionY;
                              addChild(holder);
                              trace(holder.width)
                              trace(stage.stageWidth)
                              btn.x = 250;
                              btn.y = 300;
                              holder.addChild(btn);
                              side1.width = holder.width / 2;
                              side1.height = holder.height;
                              side1.x =  -  side1.width;
                              side1.y = 0;
                              holder.addChild(side1);
                              side2.width = holder.width / 2;
                              side2.height = holder.height;
                              side2.x = holder.width + side1.width;
                              side2.y = 0;
                              holder.addChild(side2);
                              //btn.addEventListener(MouseEvent.CLICK, closedoors);
                    private function closedoors(e:MouseEvent):void
                              btn.removeEventListener(MouseEvent.CLICK, closedoors);
                              TweenLite.to(side1, .8, {x:0, ease:Bounce.easeOut});
                              TweenLite.to(side2, .8, {x:side2.width, ease:Bounce.easeOut});
                    private function opendoors():void
                              TweenLite.to(side1, .8, {x:-side2.width, ease:Bounce.easeOut,delay:.3});
                              TweenLite.to(side2, .8, {x:stage.stageWidth, ease:Bounce.easeOut,delay:.3,onComplete:addList});
                    private function addList():void
                              btn.addEventListener(MouseEvent.CLICK, closedoors);
Any help is much appriciated.
Thx pavel

you should check the allowFullScreenInteractiveProperty to see if the device allows fullscreeninteractive.  if it does, go fullscreeninteractive. if it does not, change your scalemode:
public function mainclass()
                              super();
stage.showDefaultContextMenu = false;
if(allowFullScreenInteractiveProperty){
                              stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;
                              stage.scaleMode = StageScaleMode.NO_SCALE;
} else {
stage.scaleMode=Stage.ScaleMode.SHOW_ALL
