ExtensionContext error while creating Native Extension in Flex 3.6 SDK

I'm creating native extension with Flex 3.6. Coded native side then created Flex Library Project and then create .ane file. Finally imported .ane file to myFlex Project.
Here is the problem I had. While I'm debugging app, "1046: Type was not found or was not a compile-time constant: ExtensionContext" error occurs. Attached the Library project .as class .

Thanks in Advance

package com.extension.samples
{
    import flash.events.EventDispatcher;
    import flash.events.IEventDispatcher;
    import flash.external.ExtensionContext;

    public class NetworkConnectionANE extends EventDispatcher
    {
        public var _extContext : ExtensionContext;

        public function NetworkConnectionANE(target:IEventDispatcher=null)
        {
            _extContext = ExtensionContext.createExtensionContext("com.extension.samples.NetworkConnectionANE", null);
            super(target);
        }
        public function Connect(path:String):int
        {
            return _extContext.call("nativeFunc", path);
        }
        public function dispose():void
        {
            _extContext.dispose();
        }
    }
}

Edit: I tried to use .swc file that created from library project in another Flex Desktop app, but the same error
Also tried with _extContext = ExtensionContext.createExtensionContext("com.extension.samples.NetworkConnectionANE","");
Edit: The problem about Flex SDK,no problem in SDK 4.6. Now the question is, How to use Extension in lib project in Flex 3.6 SDK ?

I had the same problem but it was resolved in the following way:

  1. File > New > Flex Library Project
  2. Check the "Include Adobe AIR Libraries" option

Right click on the project in flash builder goto properties of project and add air libraries in the flex library compiler.

As I know ExtensionContext.createExtensionContext() can be null in these cases:

  1. The call is not in an .ane file. You cannot call this from a .swc or a .swf file. In other words it needs to be compiled to an .ane file before calling it.

  2. You try to use the extension in a platform, that is not supported by the extension. For example you try to use an iOS extension on PC.

  3. The ID for the extension does not exists. The extension ID must be the same, as the one you specify in the extension.xml like:

    <extension xmlns="http://ns.adobe.com/air/extension/3.5">
    <id>com.extension.samples.NetworkConnectionANE</id>
    <versionNumber>0.0.1</versionNumber>
    ....

btw you dont need to set the second parameter of the ExtensionContext.createExtensionContext call, unless you want to specify OS-specific APIs (I havent even seen apps, that do this)
