title: Eclipse automatic generate fingerprint sha1 for every android project?
body: <p>i getting in started with the google drive api, and i'm following the tutorial at <a href="https://developers.google.com/drive/quickstart-android" rel="nofollow">https://developers.google.com/drive/quickstart-android</a>. I need to generate a fingerprint sha1, but i see in the preferences of eclipse (preferences > android > build) an existing fingerprint sha1, associated with my project. So i have some question in my mind:</p>
  
  <ol>
  <li>Eclipse generate fingerprint sha1 for each project?</li>
  <li>What's the function(s) of fingerprint sha1? Only for certification that i write the app?</li>
  </ol>
