R – Air app swf assets in ApplicationStorageDirectory produce Sandbox Violation

airapache-flexSecurity

I have an Air application that lets users import jpg, png and swf files and use them as the source to an Image which they can drag around a Canvas.

The import function copies the selected file to an images directory inside ApplicationStorageDirectory.

When I click on an Image that has an swf as its source, I get a Security Sandbox Violation (eg. SecurityDomain 'app-storage:/Project1/images/menuBarBkgd.swf' tried to access incompatible context 'app:/Main.swf'). My mouseDown handler doesn't get called so I can't select it and allow it to be dragged.

Obviously this has something to do with the app: domain, but how do I get around this?

Why not use mouseChildren = false to block the mouse from accessing the image at all? A Sprite belonging to the AIR application could show the image, and handle incoming MouseEvents itself. Alternatively, you could read the BitmapData from your loaded image and use that to populate a new instance of Bitmap, native to the AIR application.

R – AIR: Security Sandbox Violation when using remote images

This security sandbox issue is specific to dragging UIComponents that have Image components in them. The Image components reference external images. I've looked everywhere and every post I run into the thread ends unanswered, which typically means its a bug.

My bootleg workaround? After the image has downloaded to the Image component, cache it as a bitmap and reassign the Image components source to the Bitmap. This fixed the issue for me:

private function authorImageLoadComplete(event:Event):void {
    var bp:Bitmap = dupeImage(authorImage);
    authorImage.source=bp;

}

private function dupeImage(source:Image):Bitmap {
    var data:BitmapData = Bitmap(source.content).bitmapData;
    var bitmap:Bitmap = new Bitmap(data);
    return bitmap;
}

Then your image tag in your UIComponent:

<mx:Image id="authorImage" complete="authorImageLoadComplete(event)"></mx:Image>

Best of luck guys

R – Security Sandbox violation for a Socket in AIR app

The issue had nothing to due with the security sandbox, the error was misleading. I had the wrong IP. There was no server listening at that IP, and it simply was failing to connect.
