/**
 * This activity demonstrates how an app can integrate its own custom app restriction settings
 * with the restricted profile feature.
 *
 * This sample app maintains custom app restriction settings in shared preferences.  When
 * the activity is invoked (from Settings > Users), the stored settings are used to initialize
 * the custom configuration on the user interface.  Three sample input types are
 * shown: checkbox, single-choice, and multi-choice.  When the settings are modified by the user,
 * the corresponding restriction entries are saved, which are retrievable under a restricted
 * profile.
