title: free youtube API Key to use with android
body: <p>I'm building android application to list videos from youtube, I've read the API documentation and created developer account on google.
  I'm trying to get the API but it require me to have an android certificate account,
  why do I need this, even I want to list videos without any modification, why it does not need that account for IOS developers, it is just click the generate API and done. ??
  is there is any free API key for testing.</p>
  
  <p>Thanks,</p>
