13 * This class is a thin wrapper around the framework AppWidgetProviderInfo class. This class affords
14 * a common object for describing both framework provided AppWidgets as well as custom widgets
15 * (who's implementation is owned by the launcher). This object represents a widget type / class,
16 * as opposed to a widget instance, and so should not be confused with {@link LauncherAppWidgetInfo}
