How to put Google Cloud Messaging notifications in my android app?
2nd day I figure it out, I’m already confused, on habrahabr in the articles they write that a .jar library is needed, in the official Android documentation they write what needs to be downloaded to the android sdk "google play services" and imported into your project as a library.
I am confused how to do. I need to do only a part on Android, another person will do it on the server.
Please explain, or give a link, where everything is told, which library to use, what to write where, etc. It will be even better if someone takes a couple of minutes and explains in icq, skype, vk, etc. I will be very grateful.

described in steps
developer.android.com/google/gcm/index.html
1. activate api for your application
developer.android.com/google/gcm/gs.html
create a project in the google api console,
include the checkbox among the entire list of available api Google Cloud Messaging
console lives here https://code.google.com/apis/console/?noredirect&pli=1
2. connect Google Play Services import the project itself, which is in
google_play_services/libproject/google-play-services_lib
imported project add jar from google_play_services/libproject/google-play-services_lib/libs/google-play-services.jar
this is necessary in order to drag the resources necessary for the library that are not packed into jar
