Android: String set preference is not persistent

Question

I have a problem with storing string set preference. I have these utility methods for storing:

public static void putStringSet(SharedPreferences pref, Editor         


        

Answer 1

This has a ridiculous amount of duplicates - I bet that you do :

set = prefs.getStringSet("X", new HashSet());
set.add("yada yada");
prefs.putStringSet("X", set);

In short android sees that set and the one inside refer to the same set and does nothing. Correct ?
