load PDF file inside the application (Android and Ipad)

Want to open PDF file inside the application. I try this code, its working in the PC but when I publish this, as an APK file it’s not working in my android device

package {

                import flash.display.SimpleButton;

                import flash.events.MouseEvent;

                import flash.events.Event;

                import flash.html.HTMLLoader;

                import flash.net.URLRequest;

                public class bpdf extends SimpleButton {

                                public function bpdf() {

                                                // constructor code

                                                 this.addEventListener(MouseEvent.MOUSE_DOWN,downF) ;

                                }

                                private function downF(e:Event):void {

                                                var htm:HTMLLoader= new HTMLLoader();

                                                htm.load(new URLRequest("test.pdf"));

                                                htm.width=200;

                                                htm.height=300;

                                                htm.x=50;

                                                htm.y=20;

                                                this.parent.addChild(htm);

                                                // create a close button for htm and add it (to this.parent) and its listener here

                                }

                                function onCloseEvent(e:Event) {

                                                if(!HTMLLoader.isSupported){

                                                                this.alpha=.1;

                                                }

                                }

                }

}
