Settings with PreferenceFragment
In Android apps, there are often settings pages that contain different options the user can tweak. The PreferenceFragment contains a hierarchy of preference objects displayed on screen in a list. These preferences will automatically save to SharedPreferences as the user interacts with them.
To retrieve an instance of SharedPreferences that the preference hierarchy in this fragment will use, call PreferenceManager.getDefaultSharedPreferences(android.content.Context) with a context in the same package as this fragment.
