Actionscript 3 :: Adobe AIR 3 Native Extensions - Android Res Folder Not Included In The .ane File?

I am trying to develop an android extension for air, but I have a problem with resources.According to this : Official adobe doc - FREContext and this Extending AIR by Oliver Goldman We simply have to add the resources we need in the res file of the Native part, then they are added inside the .ane file and passed to the final apk. In order to access them though we have to use getResourceId( "drawable.background_image" ) instead of R.drawable.background_image

But when I generate my extension, the res file is actually not even included anywhere inside the .ane file and also not inside the final apk. And I have found not a single extension on the net using resources (not even in the adobe samples)For this test I simply use the basic Hello world Vibrate test, but I added a new png in the drawable folder.As you can see while unziping the .ane file, then going to META-INF/ANE/Android-ARM the res file is absent.As a result, the program crashes when I try to access my resource FREContext.getResourceId("drawable.ppy_accessory_manage.png")

PS, here is my batch to compile the ANE :

set adt_directory=C:Program FilesAdobeAdobe Flash Builder 4.6sdks4.6.0in
set root_directory=C:UsershugoAdobe Flash Builder 4.6
set library_directory=%root_directory%HelloANELibrary
