[aerogear-dev] Android library: Are nulls icky

[Matthias Wessendorf]

returning a "null object", which does nothing would be an interesting
approach..

That said, I think on iOS (for now) i stay with the current approach
returning 'nil' - if a store,pipe,(auth)module could not be found. I guess
JS does the same.
