  <p>I've tried to follow the tutorial step by step. I don't understand what is going wrong.</p>
  
  <blockquote>
    <p>ava.lang.IllegalStateException: A fatal developer error has occurred. Check the logs for further information.</p>
  </blockquote>
  
  <p>I thought that logcat = logs and there is nothing more. So where can I find these "logs"?</p>
  
  <p>My implementation is different only in one thing. I have a ClassA which extends BaseGameActivity and then ClassB which extends ClassA and implements View.OnClickListener 
  So I have all methods from <a href="https://developers.google.com/games/services/android/init" rel="noreferrer">https://developers.google.com/games/services/android/init</a> in class ClassB</p>
  
  <p>Thanks for any help</p>
