URLLoader doesn't work(IOError #2032) in AIR SDK version 2.5

[Guest]

Hi,

I'm troubling with URLLoader.load() method only in AIR SDK version 2.5.

Simply it doesn't work...

When 'load' method is called, the IOError below is raised

Error Event message:

>IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: http://localhost:8888/login/remoteLogIn?account=xxx" errorID=2032

# Additionaly, HTTPStatusEvent.status = 0

At the same code, same environment, it works if I chage AIR SDK version from 2.5 to Other(2.0/1.5)

#Flex SDK version is 4.1

The problem code is...

function initLoader():void{

        var url:String  = "http://hoge.com/servletName";

        var variables:URLVariables = new URLVariables();

         variables.account = "xxx";

        var request:URLRequest = new URLRequest(url);

         request.data = variables;

          var loader:URLLoader = new URLLoader(request)

         loader.load(_request);

        loader.addEventListener(Event.COMPLETE, completeEventListener);

        loader.addEventListener(HTTPStatusEvent.HTTP_RESPONSE_STATUS, responseListener);

        loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, responseListener);

        loader.addEventListener(IOErrorEvent.IO_ERROR, responseListener);

        loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, responseListener);

}

function completeEventListener(e:Event):void{

     //some codes...

}

function responseListener(e:Event):void{

     //catch error event here.

}

I tryed another environment and another simple test code but it happens in any situation if AIR SDK version is 2.5.

Is anybody has same problem and has resolution of this problem?

With this problem, I can't access http server with AIR for Android.

Thanks.

Hi

Another Chris to add to the mix.

I'm getting the same error. Im trying to convert a rather large web project to an Air for Mobile project in Flash Builder 4.5.

I have Air SDK 3.0 and Flex 4.5.1 and whilst my URL request work fine running via the desk top, it encounters IOError 2032 when running on the device.

Does anyone have a fix?

All the best

Chris,

Is this happening on iOS or Android?

[chrispeck303]

Hi Chris

I'm using a Galaxy S2 running Android 2.3.3 for device debugging.

As far as the code is concerned there isn't much to it when it finally sends the request.

public function send (params:URLVariables, method:String="GET") : void

{

    var req:URLRequest = new URLRequest(url);

    req.method = method;

    req.data = params;

    addToQueue(req);

}

then when dequeued

urlLoader.load(req);

My current theory is that it encounters an invalid SSL Certificate, though I would have thought android would spit out a warning. My system's guys are investigating that avenue. Otherwise, I'm a bit stuck.

Any advice would be appreciated.

All the best

Chris.

Hi Chris

Don't worry about this one. My bad. There was a firewall issue blocking requests to our dev servers from the phone.

Thanks for your time all the same.

Hi Chris,

Np, and thanks for the update.  Glad you got it working.

Chris Campbell,

from my post at http://forums.adobe.com/thread/943234, here is the code that reproduces this bug with Flash Builder 4.6/Air 3.1 (essentially if you load any valid https url in to UrlLoader in Flash Builder it works, however in the Android Emulator (I don't have a physical device) it gives an IOError 2032) - I see a certificate error in adb logcat but not sure if it is the cause:

Hi Chris Campbell,

I am using Flash Builder 4.6/AIR 3.1.0. I am using RESTful web service to get XML results and to display on my mobile application. I am getting the same below error when accessing the webservice from mobile app (Android - Galaxy Tab 7 inch).

Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error # 2032"] URL: http://adfdevp.alshaya.com:7013/RESTEmployeeDetails-http://adfdevp.alshaya.com:7013/RESTEmployeeDetails-EmployeeDetails-context-root/jersey/restlabEmployeeDetails-context-root/jersey/restlab

The same code is working in Flash Builder 4.6 Android emulator. I have checked Network Monitor to "Disabled" before deploying to mobile. What am i doing wrong here? I am pasting my code below-

Chris - I had already created one: https://bugbase.adobe.com/index.cfm?event=bug&id=3082218

Though - i must say that this is a type of error that seems to be happening with a lot of people (on and off with some potential fixes and regressions since 2.X) and is in the URLLoader network stack.  It basically is in the critical path of any internet based Air app.

Call me crazy, but I would say this bug is critical enough to just skip a democratized vote process and fix ASAP.  And in all honesty, there isn't enough Adobe activity in the forums for people to keep the faith and come back to vote for bugs.  From the outside, just by looking at the Adobe employee activity in forums, there seems to be a "pause" of Adobe Air right now.  It is sad because it is by far the coolest and most productive cross platform/device development environment. I am barely hanging on to the idea of building an Air app even though it is so poweful. I made a tremendous amount of progress in the first 3 days of starting to build my app and it has been on hold for 2 weeks after that.

[Fatche]

I know it's quite a late reply but I'll just add the following for future reference.

I was having a very similar problem but with a desktop app, one specific request I'd used for a long time stopped working and I would always get the generic 2032 error.

This was with a standalone Air app, using 3.1. After going through tons of posts and trying to figure out what was going on I finally solved it by simply cleaning all caches from my browsers (chrome, safari and firefox). It might seem silly since it's a standalone app but it did work.

Hope it may help someone with this problem.

[blogtom]

You may need to add an "anti cache" var like this:

requestServer = new URLRequest("http://www.example.com/yourfile.xml?nocache=" + new Date().getTime());

Hope this helps.

[banzai76_]

I'd been getting similar https and urlloader-related #2032 errors, but they seem fixed when I compile with AIR 3.3 from the Adobe Labs site (in conjunction with Flex 4.6).

[Guest]

I too get this error on FB 4.6 + AIR 3.5. Trying to get this working on iPad 5.1. Also tested on iOS 6.0 device. No luck.

My code is simple:

var loader:URLLoader = new URLLoader();

loader.addEventListener(HTTPStatusEvent.HTTP_RESPONSE_STATUS, httpResponseStatusHandler);

loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);

loader.addEventListener(IOErrorEvent.IO_ERROR, IOErrorHandler, false, 0, true);

var request:URLRequest = new URLRequest("https://somedomain/loginUser.jsp");

request.manageCookies = true;

var vars:URLVariables = new URLVariables("userName=" + usn + "&pword=" + pwd + "&LOGIN=LOGIN&operation=CPLOGIN");

request.data = vars;

loader.load(request);

This code works on iPad emulator but not on iPad itself.

Any help will be appreciated.

My Best,

Suat

EDIT: I am also getting:

IDS_CONSOLE_SANDBOX

IDS_CONSOLE_NOT_PERMITTED

[banzai76_]

Do you have a valid security certificate for the domain of the URL you are calling? If you don't, it will fail. This is a known AIR for iOS bug.

If you can use the same code to successfully download a file from that domain using http (not https), then this would likely be the explanation.

[Guest]

Thank you for your reply.

I added an image file to the root of the domain and downloaded it. No problems.

We debug'ed the backend side. The loginUser.jsp file clearly returns 302 status with a redirection url but I receive this as an ioError. This is totally strange.

AFAIK the cert I use is valid. A few developers are using it with no problems but of course this dows not mean that it is valid. I'll check it.

I don't know what to do next.

Any further help will be appreciated too.

My Best,

Suat

[banzai76_]

I would suggest as next steps:

1. Download that image file again, this time using https. If that works then you know that there are no security problems.

2. If possible, submit the login details directly to whatever URL you are trying to redirect to, and see if that works?

[Guest]

1. I downloaded the file with https with success. No problems at all.

2. I tried this. Result is the same. ioError.

Thanks again.

[Guest]

The last post says that https calls are not allowed in Adobe Air. Tell me that it is not true.

http://stackoverflow.com/questions/10249793/problems-with-https-on-ipad-from-air-app

[banzai76_]

That isn't true.

HTTPS is supported in AIR, including on iOS. I'm using it in development right now with exactly the same code as you. There are live apps in the itunes app store that use it, but there also a lot of posts around like this one where people are having trouble.

In the test where you submitted data directly to the redirected url, can you see what the server log says it is returning? i.e. does it it receive the request and respond correctly?

I'm out of ideas really. Maybe you could it on an android phone and try it from a swf hosted on the website? Just to see if the code works in those situations?

[Guest]

I didin't like it but i soved the issue another way. I created a StageWebView and moved it outside the stage. Made the https call with it and thats all. Cookie created. All other services are now accessible.

Thanks for your help banzai. I'm appreciated.

[sherif_elshazli1]

We're still experiencing this bug occasionally.

We are using URLLoader to communicate with a php server. This happens under AIR 15 beta downloaded from adobe labs, on iOS, during the login call.

We can see in the server's logs that the response has been dispatched OK but it just doesn't reach the app. After a while, around 1 min, the IOError StreeamError comes with status 0.

This never happened on the first app install. It reproduces more often when closing the app during the login call, and restarting.

The php server is hosted with Amazon and we'd never experienced any problems with them.

The call is http not https.

[chris.campbell]

Sherif.elshazli,

Can we start a new thread?  This one is 4 years old and has conflicting information.  When adding the new forum post, please feel free to reference this thread and please include a link to your bug report.

Thanks,

Chris

[Yozef0]

Sounds like this thread is still open. I wonder how active the community still is..

I will narrow down the Issue. AIR 3.4 Flex 3.6.

var loader:URLLoader = new URLLoader();

  loader.addEventListener(Event.COMPLETE, resultUpdatedNotificationsEvent);

  loader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler); // <-- This gets fired with a IOError id 2032

  loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler); // <-- then this gets status : 0

  loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);

var request:URLRequest = new URLRequest('https://

loader.load(request);

On Mac - All Ok... runs well.

On Window - I get the IOErrorEvent.IO_ERROR event. How come?

[chris.campbell]

Hi Yozef0,

Can you try this out with AIR 19?  If it still happens, please open a bug report at https://bugbase.adobe.com and attach a sample project.  Once added, please let me know the bug number and I'll have someone take a look.

Thanks,

Chris
