/**
* This activity is an example of a simple settings screen that has default
* values.
*
* In order for the default values to be populated into the
* {@link SharedPreferences} (from the preferences XML file), the client must
* call
* {@link PreferenceManager#setDefaultValues(android.content.Context, int, boolean)}.
*
* This should be called early, typically when the application is first created.
* This ensures any of the application's activities, services, etc. will have
* the default values present, even if the user has not wandered into the
* application's settings. For ApiDemos, this is {@link ApiDemosApplication},
* and you can find the call to
* {@link PreferenceManager#setDefaultValues(android.content.Context, int, boolean)}
* in its {@link ApiDemosApplication#onCreate() onCreate}.
