How use Android Backup Service?

Ok, in documentation is that SharedObject work only IOS, but if I uses File.applicationStorageDirectory, then still not work...

I try set up android:backupAgent in androiddescriptor.xml with Register for Android Backup Service | Android Developers but i have only package name for Actionscript and not path for AIR Android Context class.

Some solution?
