title: Rails - Google Cloud Messaging server side with Rails
body: <p>I am building a sample android app with notifications and live chatting, i am trying to use GCM so that the server (Ruby on Rails) can talk to the clients (Android).</p>
  
  <p>For the Android part, I'm following this <a href="http://hmkcode.com/android-google-cloud-messaging-tutorial/" rel="nofollow">tutorial</a>, but for Rails, I found many gems like <a href="https://github.com/rpush/rpush" rel="nofollow">rpush</a>, <a href="https://github.com/NicosKaralis/pushmeup" rel="nofollow">pushmeup</a> and more, but I am new to Rails so I couldn't figure were should I write the code and how to run it and test it.</p>
  
  <p>Can someone walk me through it or give me a link to a detailed tutorial?</p>
  
  <p>Thanks in advance.</p>
