I have a news website and i'm developing an android app that gets the news articles from a url as JSON and everything is working well. Now i want to implement push notifications in the android app, so whenever a new article is published a notification with the article's title appears on the android device screen. (like facebook).
I made some research and i found that i have to use Google Cloud Messaging (GCM) but it's not that easy to implement, is there any easy-to-follow tutorial about that ?
