I really need to know what is the best and possibly easiest solution for this. For Android I set up push notifications as per the GooglePushNotification sample code, which uses GCM. I had no problems and it works very well. I was thinking about using parse for iOS, so my question is: will I be able to send a notification from an iOS device to an Android one or vice versa with these 2 methods?
If not is there a service for both, I need notifications for my multiplayer game so I can send notifications from device to device. I dont want a service that is setup to broadcast notifications to every device that is registered.
