Hi all,
I am using AIR 1.5 SDK.
I am trying to find a way to build patching mechanism for my AIR app, which
consists modules, sqlite DBs, and other files, by updating ONLY files that need
to be updated.
I know that this is not possible using AIR Update Framework because the way I
understand it works is that any update that you have both minor and major, you
will have to reinstall everything. This is a pain if you have a huge size AIR
app.
I have sort of an idea to build my own update mechanism but in order for this
to work, I will need to be able to do update operation on my AIR app files.
Since "app" domain doesn't allow us to do that, I have to find a place where
updates can take place and my app could still work. I read that "app-storage"
allows you to do all of that.
Okay... so I build a really simple AIR app that the sole purpose is to load swf
module from "app-storage" to prove my theory.
So here's my AIR app code the short version:
<mx:WindowedApplication>
<mx:Script>
private function loadSwf():void
{
var dir:File = File.applicationStorageDirectory
dir = dir.resolvePath("SimpleSwf.swf");//SimpleSwf is the
module
var myURLRequest:URLRequest = new URLRequest(dir.url);
var myURLLoader:URLLoader = new URLLoader();
myURLLoader.dataFormat = URLLoaderDataFormat.BINARY;
myURLLoader.load(myURLRequest);
myURLLoader.addEventListener(Event.COMPLETE,loadModuleCompleteHandler);
}
private function loadModuleCompleteHandler(pEvent:Event):void
{
var context:LoaderContext = new LoaderContext();
context.allowLoadBytesCodeExecution = true;
context.applicationDomain = ApplicationDomain.currentDomain;
var moduleLoader:Loader = new Loader();
var loader:URLLoader = URLLoader(pEvent.target);
moduleLoader.loadBytes(loader.data,context);
container.addChild(moduleLoader);
}
</mx:Script>
<mx:VBox width="100%" height="100%">
<mx:Button label="Load SWF" click="loadSwf()"/>
<mx:UIComponent id="container"/>
</mx:VBox>
</mx:WindowedApplication>
The result is:
When I click the button "Load SWF", I could see that the loader loads the SWF
correctly (it got the right size, etc) but I didn't see the module shows up on
the screen at all.
I didn't know what I do wrong.
Please enlighten me.
