init() failing with OAuthException

[GoogleCodeExporter]

What steps will reproduce the problem?

1.Running FacebookMobile.init(MY_AP_ID, facebookInitHandler);
causes the success object in the callback to be null and fail has an error of 
""OAuthException" "An active access token must be used to query information 
about the current user." 

Is it possible I set something up incorrectly on Facebook's developer page?  I 
know I am using the correct ap id, but I am not using the Ap Secret any where, 
should I be?

What version of the product are you using? On what operating system?
I am using version Mobile 1.8.1 with Flex 4.6.  The issue is happening on both 
IOS and Android.

Any help would be greatly appreciated.  I have been struggling with this all 
day.

We just forked the library for mobile and fixed the 402 issue.
The problem was with the expiration date of the token returned by the API. It 
returns the amount of seconds from now until the token expires. Just adding the 
current date in seconds seemed to fixed the problem.
We also fixed the JSON problem with AIR 3.0+

Take a look and let us know if it works for you:

I've got same error. Try to use MobileLoginWindow directly.

Any workaround? using "The Dam Armada" com provides errors (about PNG ENCoder?)

Any working version of FacebookMobile for Flash builder 4.6 would be appricated 
:)

Problem still exists. Can't connect to facebook because of the following Error:

----- > :CLASS: fbInitCallbackHandler

error: An active access token must be used to query information about the 
current user.
error: 2500
error: OAuthException

Please get this error fixed!! The latest release is nearly 7 Months old. Please 
don't let this project die.

THE SOLUTION:

from : http://forums.adobe.com/thread/928058

FacebookMobile.init("xxxxxxxxxxx", loginHandler);

function loginHandler(response:Object, fail:Object):void

{  

    if(response)

     {

          // good the user is already connected

     }

     else

     {

          var myWebView:stageWebView = new StageWebView();

          myWebView.stage = this.stage;

          myWebView.viewPort = new Rectangle(0,0,stage.stageWidth,stage.stageHeight);

          FacebookMobile.login(handleLogin, stage, extendedPermissions, myWebView);

     }

}

To really solve problem, do it:

if (html.location.indexOf('?#') != -1) {
    params = html.location.slice(html.location.indexOf('?#')+2);
    ...

see git diff...

solved the issue with 
if (html.location.indexOf('?#') != -1) {
    params = html.location.slice(html.location.indexOf('?#')+2);

So not sure if this will help anyone in the future that has this kind of 
problem, but for me... the reason was I was asking for "user_email" in the 
login perms.  Turns out that you can't initially ask for any of the "user_XXXX" 
permissions until after you have a token... then ask for extended perms.  once 
I changed my login perms to only read var perms:Array = ["read_stream"];, 
everything worked as expected
