title: Commiting google-services.json to GitHub
body: <p>I am creating a public android project and I am using Google Sign-In service. I am doing it according to <a href="https://developers.google.com/identity/sign-in/android/start-integrating" rel="noreferrer">this tutorial</a>. As it says, I have got the google-services.json file. </p>
  
  <ul>
  <li>Do I need to commit the above file to Github? </li>
  <li>Do other developers (If someone contributes) need this file? </li>
  <li>Or, do they have to create there own? </li>
  <li>By the way I am using Travis-CI. Will this file affect to CI build?</li>
  </ul>
