Can someone help me get a basic understanding of how to add push notifications to an app? I've been trying to read up on it, and it's confusing the heck out of me. It isn't clear if this is something that I'm supposed to write server side code for, or if I'm supposed to somehow integrate into some 3rd party push notification platform. Right now, I have an ios/android app I'd like to add simple notifications to: 1) I want an admin to be able to sign into some server interface, and be able to send a message out to everyone (like "Hey guys, server is going down for the night" or something like that). 2) The app has a basic newsfeed type page. I guess maybe it's more like a really simple comment wall. Any user can create a comment, and it gets appended to the newsfeed wall. Nothing fancy, but I want the server to send out notifications to all the app users that the newsfeed wall has been updated (and put a little red unread count on the app icon). Is this all as complicated as it seems? Is there some easy ios/android service I can plug into to get this functionality? Or do I need to program all this code from scratch?
