Adobe Flex Air Android App

[dmerck]

I am running an Adobe Flex Air Android App and am trying to load an Print2Flash swf from a web server. I am getting a sandbox security error. Should I be downloading the file to a local location first or is their a way to give this action permission. I was able to do this with flash without issue by adding a trusted location. Any ideas would be appreciated.

Thanks,

I have explored a few things. I have the example in the SDK working in a Flex 4.1 App using Flash Develop. I have the example in the SDK working in a Flex 4.1 AIR App using Flash Develop. I have not been able to get the Flex Sample to load/display the document using Flash Builder Burrito using Flex 4.5.

I compared APILC.domain in Print2Flash/Print2FlashDoc.mxml

In FlashDevelop using Flex 4.1 AIR
APILC.domain=app#Print2FlashFlexAirTest

In FlashBuilder Burrito using Flex 4.5 Mobile AIR
APILC.domain=null

I suspect this may be the result of it not connecting/loading/displaying the document in a View.

Anyone have any thoughts?

Is there a solution for this?

Hello,

I'm working on an application cross-platform (Web-desktop-tablet).
This application load a print2flash file. This work perfectly on web but i have an error on android.

I modified the class Print2FlashDoc3 to resolve secutiy problem

Code: Select all

package utils {
	import flash.display.*;
	import flash.events.*;
	import flash.net.*;
	import flash.utils.*;
	import flash.system.*;

	public class Print2FlashDoc3 extends Loader {
		private var contentwidth:Number, contentheight:Number;
		private var loadTimer:Timer;
		private var urlLoader:URLLoader;
		public static const ONLOADEVENT:String="onLoaded";
		public static const IO_ERROR:String="ioError";

		public function Print2FlashDoc3(url:String,x:Number,y:Number,width:Number,height:Number,parent:DisplayObjectContainer)
		{
			loadTimer=new Timer(10);
			loadTimer.addEventListener("timer", checkLoaded);
			this.x=x;
			this.y=y;
			contentwidth=width;
			contentheight=height;
			
			contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
			
			loadDoc(url);
			parent.addChild(this);
		}

		private function ioErrorHandler(e:IOErrorEvent):void
		{
			loadTimer.stop();
			dispatchEvent(new Event(IO_ERROR));
		}
		
		public function loadDoc(url:String):void {
			visible=false;
			/*try {
				Security.allowDomain("*");
				load(new URLRequest(url));
				loadTimer.start();
			} catch (error:SecurityError) {*/
				urlLoader = new URLLoader();
				urlLoader.dataFormat = URLLoaderDataFormat.BINARY;
				urlLoader.addEventListener(Event.COMPLETE, completeHandler);
				urlLoader.load(new URLRequest(url));
				 
			//};
		}
		
		private function completeHandler(event:Event):void
		{
			try {
				var data:* = event.target.data;
				if (data is ByteArray) {
					var context:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain);
					context.allowCodeImport = true;
					loadBytes(data as ByteArray,context);
					loadTimer.start();
				}
				
				urlLoader = null;
					
			} catch (error:Error) {
				trace(event.toString());
				trace(error.toString());
			}
		}
		
	    public function checkLoaded(event:TimerEvent):void {
			var doc:MovieClip=getDoc();
			if (doc && doc.DocArea) {
				trace('doc',doc,'doc.DocArea',doc.DocArea);
				doc.init(contentwidth,contentheight);
				trace('here');
				// lors de la suppression du document, il faut supprimer l'écouteur d'evenement
				// sur 'FullScreenEvent.FULL_SCREEN' sur le stage  ajouté par print2flash
				// sinon on à une erreur lorsqu'on essaye de passer en plein écran a partir du moment
				// où on a ouvert plus d'un document....
				stage.removeEventListener(FullScreenEvent.FULL_SCREEN, doc.OnFullScreen);
				loadTimer.stop();
				visible=true;
				dispatchEvent(new Event(ONLOADEVENT));
			}
        }
		
		public function getDoc():MovieClip {
			return content as MovieClip;
		}
	
	}
}

but now, i have an error #1009 at the end of loading the file :

Code: Select all

Exception fault: TypeError: Error #1009: Cannot access a property or method of a null object reference.
	at print2flash_fla::MainTimeline/frame2()

and :

Code: Select all

Exception fault: TypeError: Error #1009: Cannot access a property or method of a null object reference.
	at print2flash_fla::MainTimeline/SetAccessiblePages()
	at print2flash_fla::MainTimeline/SetCurrentPage()
	at print2flash_fla::MainTimeline/ZoomTo()
	at print2flash_fla::MainTimeline/SetBaseParameters()
	at print2flash_fla::MainTimeline/setSize()
	at print2flash_fla::MainTimeline/init()
	at utils::Print2FlashDoc3/checkLoaded()[C:\Users\dabernatm\workspace\LMS_NAVIGATEUR_LIB_V3\src\utils\Print2FlashDoc3.as:76]
	at flash.utils::Timer/_timerDispatch()
	at flash.utils::Timer/tick()

I think the first error is the origin of the problem.

If someone have an idea.

Can you open this document on Android directly in the browser without your application?

[mdabernat]

I tested on 3 different version of android: 3.2/4.0.4/4.2.2:

in a web browser the file is displayed on version 3.2.
in my app, all the versions return the same error

Code: Select all

Exception fault: TypeError: Error #1009: Cannot access a property or method of a null object reference.
	at print2flash_fla::MainTimeline/frame2()

Is it an AIR application you are developing? If so, could you send us an application sample which demonstrates this problem to our support e-mail?
