Flex Mobile : URLLoader bytesTotal always at 0 when loading file

Question

Hi !
I'm trying to load external file with UrlLoader in a Flex Mobile Project ( Initialy it was with Data/Services Options of Flash Builder, but I have the same problem ). On the complete event, it work on the desktop ( bytesTotal, xml... ), but when i install my application on my nexus one ( air version : 2.5.0.1660 ), i've no data ( bytesTotal = 0 ), but the cache of the application has grown
The application has these autorisations :
            <uses-permission android:name="android.permission.INTERNET"/>
            <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
            <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
If someone can help me...
Thx !

After messing with the URLLoader for a native windows AIR app I gave up on it. That object will return 200, ok, complete, while failing to do what it says it did.
I never found any way to catch a real error from the server with any of the event listeners for URLLoader.  Instead I used HTTPService, it acutally returns useful data on server errors.  Here is an example, all this is tucked into my own class.
var service:HTTPService = new HTTPService();
               service.url = url;
               service.resultFormat = HTTPService.RESULT_FORMAT_E4X;
               service.method = URLRequestMethod.POST;
               service.addEventListener(ResultEvent.RESULT,serviceResult);
               service.addEventListener(FaultEvent.FAULT,faultResult);
               service.send(vars);
private function serviceResult(eResult:ResultEvent):void
               var objResult:Object = eResult;              
               if( objResult.result is XML )
                    xmlData = eResult.result as XML;
                    trace(xmlData);
                    dispatchEvent( new Event('eComplete') );
               else
                    //something wrong
                    trace('BAD! No XML Returned: '+eResult.result);
                    dispatchEvent( new Event('eError') );
private function faultResult(e:Event):void
               if( e is ErrorEvent )
                    trace( ErrorEvent(e).text );                   
               else if ( e is FaultEvent )
                    trace( FaultEvent(e).message.toString() );
               else
                    trace( 'Unhandled error' );
               dispatchEvent( new Event('eError') );
