Why didn't we use "this" instead of declaring an empty Context mVariable?

You can only use this if the object is a Context, or sub-class of Context. The sub-classes you'd use in writing Android apps are top-level things: Activity, Application, and Service, as well as sub-classed variations on those. Other common Android components like Fragments and ListAdapters aren't sub-classes of Context. You either need to pass it a Context or use a getContext()/getActivity() method if the class has one (like Fragment).

Makes sense, but need to reach Android Fragments course to gain better understanding of it probably, thanks for your answer.
