I’m writing an Android app and I have a loader that brings in an external swf. I want to create an event so that when the back button is pressed it unloads the swf. But I can’s seem to get it to work.

Any ideas?

```auto
private function jumptest (event:TouchEvent):void{
            var infoloader:Loader = new Loader();
            var infoURL:URLRequest=new URLRequest("MapInspectorGW.swf");
            infoloader.contentLoaderInfo.addEventListener(Event.COMPLETE, infoDone);
            infoloader.load(infoURL);
            
            NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_DOWN, infoBack);
        }
        

    private function infoDone (loadEvent:Event)
    {
        addChild(loadEvent.currentTarget.content);
    }
    
    private function infoBack (event:KeyboardEvent):void
    {
		if (event.keyCode == Keyboard.BACK)
		{
       		infoloader.unload();
		}
        
    }

```
