Yes, though they are more limited in Android: they are just buttons that can jump to the app (= launch a specific intent). On the contrary, the new iOS notifications can have a real interaction; e.g.: you can answer to a message within the notification itself and never switch context.
AFAICT, that's because it's a SMS application, so it's got a special hook being called when a SMS arrives. For normal notifications (delivered through GCM), that's not possible.
