The preferences portion of an application
should be ran as a separate Activity that extends
the PreferenceActivity class. In the PreferenceActivity, a
PreferenceScreen object should be the root element of the layout.
The PreferenceScreen contains Preference elements such as a
CheckBoxPreference, EditTextPreference,
ListPreference, PreferenceCategory,
or RingtonePreference.
All settings made for a given Preference will be automatically saved
to the application's instance of SharedPreferences. Access to the
SharedPreferences is simple with getSharedPreferences().
Note that saved preferences are accessible only to the application that created them.
