The problem is in implicit broadcast that you're making in sendWidgetRefresh. You can break through the ban by defining a component name in your intent.

    ComponentName componentName = new ComponentName(context, WorldClockWidgetProvider.class);
    broadcast.setComponent(componentName);
    context.sendBroadcast(broadcast);
}
