By this you scale your app according to devise screen size

private var originalW:Number=1024.0; // this is my app width

private var originalH:Number=600.0; // this is my app height

private function init():void{

navigator.firstView = homeView;

var deff:Number = Math.abs(( originalW – this.width ) ) * 100 / originalW ;

deff = ( 1 * deff ) / 100 ;

if ( deff != 0 && deff != 1 ) {

if ( originalW < this.width ) {

scaleX = 1 + deff;

trace ( "scaling width Bigger= " + scaleX );

}

else {

scaleX = 1 – deff;

trace ( "scaling width smaller = " + scaleX );

}

}

//——————-

deff = Math.abs(( originalH – this.height ) ) * 100 / originalH ;

deff = ( 1 * deff ) / 100 ; // get scaling percent on the respect on 1

if ( deff != 0 && deff != 1 ) {

if ( originalH < this.height ) {

scaleY = 1 + deff;

trace ( "scaling height Bigger= " + scaleY );

}

else {

scaleY = 1 – deff;

trace ( "scaling height smaller = " + scaleY );

}

}

}
