/*  
AsyncTask can not be coded as instance inner class (non-static).
An instance inner class is tied to an instance of the containing class and it cannot be changed.
So, it is not possible to relink an instance of an async task to the new instance of the activity (on rotation).
What happens : when the async task finishes and onPostExecute is executed, the old activity is updated and not the new one.

##Getting results from DialogFragments to another Fragment.

When setting up the DialogFragment make a call to Fragment.setTargetFragment()
Then from DialogFragment you can access the main fragment with Fragment.getTargetFragment()
Use interfaces to provide the required actions to the calling Fragment.

##Example code.

###AddFriendDialogFragment - Calls back to calling fragment.
