You could define your own extension point in the app bundle and have it 
delegate to some interface (defined by that extension point) to do the 
real work. Something like ResourceSelectionHandler. Then your UI plugin 
implements that extension point and provides and implementation of the 
interface.

You could also do it with a fragment that is hosted by the app plugin; 
the fragment can have UI dependencies but keep them out of the plugin 
itself.

Hope this helps,
