Air app on Android fullscreen

I'm building an AIR mobile app for android >= 4.0. I must be missing something or doing something wrong because no mater that i do, i can't get the fullscreen working rigth.

The tablet bottom bar always shows up. In current version the bar only shows 3 dots and have somekind of alpha but it doesn't allow me to draw above it or below it.

In my app description XML i have:

<initialWindow>

<aspectRatio>landscape</aspectRatio>

<renderMode>direct</renderMode>

<autoOrients>false</autoOrients>

<fullScreen>true</fullScreen>

</initialWindow>

And the bar is still there

Tried set the fullscreen to false and then:

stage.fullScreenSourceRect = new Rectangle(0,0,1280,768);//Capabilities.screenResolutionX, Capabilities.screenResolutionY);

stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;

No effect... the damn bar is still there.

Using FB 4.7, Air 3.8 and -swf-version=21

Any help or a pillow to put between the head and the wall would be very apreciated!!

Thanks
