Android Livewallpaper settings fail to load from 'configure...' menu

I am unable to load the live wallpaper preferences from 'Wallpaper>Configure...'.

The preferences load fine when i click the settings button from within the Livewallpaper menu. Here are some screen shots to better explain the error:

figured it out after tinkering around with the manifest file. Added an intent filter 'category.PREFERENCE' & moved BIND_WALLPAPER permission inside the service tag. here is the new manifest file:
