Deleting all but one SharedPreference

Question

I want to clear all but one SharedPreference. If I've saved 10+, is there a better way then removing each individually? This gets a bit redundant:

preferences.edit().remove("1").commit();
preferences.edit().remove("2").commit();
preferences.edit().remove("3").commit();
...
preferences.edit().remove("15").commit();

Answer 1

You could also get the value you want to keep, clear(), and re-add it before commiting.

Answer 2

you can loop through all the keys

Map<String,?> prefs = pref.getAll();
for(Map.Entry<String,?> prefToReset : prefs.entrySet()){
    edit.remove(prefToReset.getKey()).commit();
}

then skip over the key/s you dont want to remove
