UniversalPreferences.getInstance().put("string", "some value");
String stringValue = UniversalPreference.getInstance().get("string", "");

UniversalPreferences.getInstance().put("int", 30);
int integerValue = UniversalPreference.getInstance().get("int", 0);

Store and retrive Float

UniversalPreferences.getInstance().put("float", 3.0f);
float valueFloat = UniversalPreference.getInstance().get("float", 0.0f);

UniversalPreferences.getInstance().put("bool", true);
boolean bool = UniversalPreference.getInstance().get("bool", false);

Set<String> set = new HashSet<String>();
set.add("test 1");
set.add("test 2");
UniversalPreferences.getInstance().put("set", set);
Set<String> savedSet = UniversalPreference.getInstance().get("set", new HashSet<String>);
