I am using LoaderMax to load and display various assets (videos, images and SWFs)
The SWFs are saved locally and need to access parameters passed on via my Flex Mobile app.
This project was previously built in Flash Pro, and the code:
var foo = root.loaderInfo.parameters['foo'];
worked perfectly before.
Now I am in Flex (and using LoaderMax) I am unsure how to pass the parameters along/pick them up.
When LoaderMax loads the SWF, I get:
SecurityError: Error #3207: Application-sandbox content cannot access
this feature. at flash.system::Security$/allowDomain()
I tried using:
Security.allowDomain("*");
but the app seemed to freeze on the splash screen.
Any ideas?
try with this LINK. is apparently the same problem. in this link use this code:
try {Security.allowDomain("*");}catch (e) { };
I hope it will be helpful.

*** Security Sandbox Violation ***
SecurityDomain 'file:///Users/Bluebird/Desktop/Demo/Project/Level_01
/Background.png' tried to access incompatible context 'app:/project.swf'
I understand that these "security" alerts are difficult to track down and even more difficult with scant information but I thought I would ask.
I have a large Flex/AIR desktop project where the user can select images off their local drive and collage them. There are also some swfs provided which they can use as "stamps". I am getting the error below when stamps are added to the app and clicked – the stamps have eventListeners attached – but the error does not reference the stamp (swf) but instead it references the background image.
The background image is a Spark Image defined in MXML:
<s:Image id="backgroundImage" x="{renderX}" y="{renderY}"
width="{renderWidth}" height="{renderHeight}"
smooth="true" smoothingQuality="high" scaleMode="stretch"
complete="backgroundImage_completeHandler(event)" />
The complete function does nothing important. The source property for the image is defined once the user has selected a local image:
backgroundImage.source = userFile.url
I don't see anywhere to provide a loaderContextfor the Image component (one solution usually suggested for "security" errors). Also, the backgroundImage component has no eventListeners – so I am completely baffled why it is throwing an error.
I've set the Flex compiler option to -use-network = false since this is just a desktop app and that is another commonly suggested "security" fix. I am also loading the "stamp" swfs through the trick of loading them as a byteArray first – another commonly suggested "security" fix.
Can someone help me hate Flash a little less?
For a quick check and probably fix, Instead the following line:-
backgroundImage.source = userFile.url
Trying giving it the relative path to the image file instead full absolute path.
like:
backgroundImage.source = "../images/bg.png";
Also, I assume you have already provided Security.allowDomain("*") in your stamp swfs.
First of all, per the Loader documentation, if you include the swf in the installed application content there won't be any security restrictions when loading it.
Otherwise, the Image component extends SWFLoader which does have a loaderContext property. Try passing in the current domain:
new LoaderContext(ApplicationDomain.currentDomain, SecurityDomain.currentDomain)
I am working on embedding a SWF that is just a converted PDF created with InDesign. The SWF is 15 pages, 1 page per frame. It does include TLF text and there is no way around that unless the document is completely recreated in Flash. The problem is that when I load the SWF into my application, I never have access to the root MovieClip.
this.loader = new Loader();
this.loader.contentLoaderInfo.addEventListener( Event.INIT, this.loaderInitHandler );
this.loader.contentLoaderInfo.addEventListener( Event.COMPLETE, this.loaderInitHandler );
this.loader.load( new URLRequest( "assets/doc.swf" ) );
When I look at the loader after both the INIT and COMPLETE events as well as later on by stopping the app in debug mode, I do not see a MovieClip. Instead, the loader.content is of type doc_fla.MainTimeline__Preloader__ which contains two children, an empty Shape and another Loader. That loader, when checking INIT and COMPLETE events results in the exact same situation and it appears to be a never ending line of Loaders whose contents are "Preloaders".
Could anyone shed some light as to what is causing this or how I might fix it? I've poured a good 2 hours into solving this and I am no closer to a solution than when I started.
ActionScript Mobile project
Compiling using AIR 3.6
Testing in emulator as well as on iPad and on Nexus 7
I recompiled the SWF and embedded the TLF libraries (under ActionScript settings, just set the TLF swc which was already there to be embedded) in it and this seems to have fixed the issue. I swear I had tried that before to no success, but it worked this time.
I am trying to create an ad for a website. When someone clicks on the ad, it is supposed to redirect them to a website, and register the click with google analytics.
I have done this with the following script:
import flash.external.ExternalInterface;
movieClip_3.addEventListener(MouseEvent.CLICK, onClick);
function onClick(event:MouseEvent):void {
trace("hi");
ExternalInterface.call("console.log", "test");
//ExternalInterface.call("_gaq._trackPageview", "/vpv/annoncer/[firmanavn.dk]");
navigateToURL(new URLRequest("http://www.google.com"), "_blank");
}
When i run this using preview->flash and i click on the surface, (where there is a big red square called movieClip_3) It opens the webpage. However when i try to publish as html, the big red square shows, but nothing happens on click. Not even console.log. I have tried setting allowscriptaccess = always but that does not change anything.
Can you guys help me? Any help is appreciated.
Security problems?
Developers should validate all URLs before passing them to this
function.
For local content running in a browser, calls to the navigateToURL()
method that specify a "javascript:" pseudo-protocol (via a URLRequest
object passed as the first parameter) are only permitted if the SWF
file and the containing web page (if there is one) are in the
local-trusted security sandbox. Some browsers do not support using the
javascript protocol with the navigateToURL() method. Instead, consider
using the call() method of the ExternalInterface API to invoke
JavaScript methods within the enclosing HTML page.
source: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/package.html#navigateToURL()
EDIT:
Since javascript is not permitted out of the sandbox, you can try with ExternalInterface:
ExternalInterface.call("javascript_functionname", "mypage.html");
In the parameters for publishing:
'allowScriptAccess', 'always',
You can only test this on your server not locally.
I'd suggest double checking the security settings (right click on flash container->Global Settings-> Advanced -> Trusted Location Settings). Also make sure your html file contains the javascript function you're trying to execute and look for blocked pop-up notifications in the browser. Maybe you just don't allow pop-ups to run.
is there any solution on StageWebView.loadURL(), how I can handle URLs in HTML Pages which have target="_blank"?
It's a mobile Android App. (TabbedViewApplication)
Hope someone can help.
Thx
One option is StageWebViewBridge.
StageWebViewBridge is an extended version of flash.media.StageWebView.
Extends loadString method with AS3 - JS communication.
-Extends Bitmap class, you can modify his x,y,alpha,rotation,visible, etc ( Version 1 Beta )
-Communicates Actionscript with Javascript.
-Communicates Javascript with Actionscript.
-Load local files and resources in a easy way.
-Extends loadString method with AS3 - JS communication.
-Extends loadString method to load local resources.
-Lets you take an SnapShot to use as the bitmapData of the bitmap.
StageWebViewBridge source: https://code.google.com/p/stagewebviewbridge/
I never worked with the StageWebView but I know it's really limited. When using an HTMLLoader, you can set a custom HTMLHost instance that specifies to use current HTMLLoader when opening to _blank. However, I don't think it's possible with StageWebView.
public class MyHTMLHost extends HTMLHost
{
public function MyHTMLHost(defaultBehaviors:Boolean=false)
{
super(defaultBehaviors);
}
override public function createWindow(windowCreateOptions:HTMLWindowCreateOptions):HTMLLoader
{
// all JS calls and HREFs to open a new window should use the existing window
return htmlLoader;
}
}
OK, so the only solution for this problem i could found is to load the page (containing the links) as String with the URLLoader and replace its specified parts. Finally loading it via StageWebView.loadString() method.
Problems occur when the Site is dynamic and contains JavaScript. I had also replace some relative links with absolute pathes.
That's it... but I really hope that adobe makes it possible to load those "_blank" links with the StageWebView.loadURL() method.
If you want to capture when a user clicks on a link inside your StageWebView add an an event listener for location changing event (LocationChangeEvent).
This LocationChangeEvent will include the URL they are going to and target. Then you can prevent the URL from loading, let it continue (by doing nothing) or handle it any other way including loading another URL.
If you want to load another URL first stop the loading with stageWebView.stop(). You should also call event.preventDefault(). You can then attempt to
Note: There is another event called locationChange that may be helpful.
As it was declared as an official bug, adobe QA Owner Sanjay C. added a comment: "Able to reproduce the issue with the attached project. Sending to IRB."
So, hope the next Build will come up with the fix wit it.
Best regards
The code at the bottom of this post nests an AS2 "player" inside a Flex app (AS3). Look at the part that says "[AS2 player swf]". That AS2 player swf has almost no code - just one function that loads an asset from a remote server. Very simple:
this.onLoad = function(){
content.loadMovie("http://URL_TO_REMOTE_SWF");
};
And it has no other assets. Just one MovieClip - "content".
So we've got a Flex app that loads an AS2 swf that loads a remote swf. No dice. Remote swf doesn't load and display. No errors reported.
Important: The AS2 app on its own works. If I go navigate to it in my file system and double click, remote swf does indeed load and display. So I've established that the unwrapped AS2 swf player works and does indeed load remote swf's. Something about nesting that player inside the Flex app creates a problem. Are you not allowed to do this - 3 levels of swf nesting (child - parent - grandparent)?
UPDATE: Target remote swf's load and display fine directly in Flex as well (skipping AS2 swf). So problem doesn't appear to be with AVM1/AVM2 discrepancy between target content and Flex app. Could be AVM1/AVM2 problem with how the Flex app displays the AS2 swf but only when it contains content.loadMovie("http://URL_TO_REMOTE_SWF"). Loads and displays without that line.
UPDATE: This is a Flex packaged IOS application and thus is subject to ActionScript restrictions for dynamically loaded code. But it doesn't work in a regular Flex (non packaged IOS) app either which is not subject to these limitations. THE FOLLOWING CODE SHOULD WORK AS FAR AS I CAN TELL IN A REGULAR FLEX BROWSER BASED APPLICATION.
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

Since all Sprites and MovieClips are both display objects and display object containers, you could theoretically keep nesting them forever. There are physical restraints, of course, but I see no reason why there should be a limit other than memory and processing power (at some point, refreshing the screen will become sluggish, and eventually painful to wait for).
I've searched the web to see if I could find any information about a built-in limit enforced by the AVM, any documents or error codes that would suggest there is one, but I couldn't find anything at all. Of course, that doesn't mean there isn't - it just means the limit hasn't been reached by many people yet ;)
So if anyone else knows more...
EDIT
Since the information about your loaded MovieClip is new, here's my update: AVM1 (AS1 & 2) SWFs don't always execute in the same way when loaded into an AVM2 (AS3) movie. This has nothing to do with the number of nested display objects. I originally thought this was because the _lockroot property was removed in AS3, but I've searched a bit and found out it is assumed true by default, and should therefore not be a problem.
There may be many things about your scenario that are different from when the file runs on its own, and I would start by looking at these:
Do you use relative path names to load other data into the AS2 swf?
Do you get any error messages (particularly, security sandbox violation errors)?
Does your AS2 SWF rely on external variables to be set (FlashVars)
Does your AS2 SWF need ExternalInterface access?
FINAL EDIT
Since this new info has just come up:
There is absolutely no way to execute dynamically loaded AVM byte code on an iPad at runtime, for the same reason that there is no Java VM and no Flash Player for iOS: Apple does not allow the execution of dynamically loaded byte code at all. Period.
Hence, you can load and play SWF animations, but not ActionScript. It will simply be ignored. Also, neither of the apps that you did run is in fact AVM byte code - they are compiled into LLVM byte code instead.
You will have to find a way to check for the end of the animation that does not involve stop() commands. Perhaps this can be done by checking frame numbers from your AS3 container?
To answer you question directly, yes, you can load AS2 swfs that way. And you code looks correct to me.
I suspect it is loading the AS2 swf fine, but that the AS2 swf is not initializing correctly for some reason. Perhaps it is a video player that has no visible assets besides the loaded video. AS2 tends to fail without throwing errors, which makes it hard to debug. I would suggest publishing an AS2 swf with some graphics in it but with no code that could fail. No code at all. Maybe just a timeline animation of a moving circle or something, then load that. In that way you can eliminate your Flex code as the source of the problem.
If it turns out that your test movie works, then you will need to determine what resource the loaded swf is expecting that it is not receiving.
