Thank you for the insights. However the adapter is not linked to any one activity - in fact I re-use it in multiple activities that have tables. It's a class of its own. The lookup of the SharedPreferences is independent of the activity that may be using the adapter. So I'm afraid I cannot use the options you proposed. (I am not using fragments)
