title: Google Maps Android API authentication issue
body: <p>I'm trying to use Google Maps on Android, but I'm getting these messages:</p>
  
  <p><code>I/Google Maps Android API(21300): Failed to contact Google servers. Another attempt will be made when connectivity is established.</code></p>
  
  <p><code>E/Google Maps Android API(21300): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).</code></p>
  
  <p>This is my Manifest file:</p>

      &lt;/application&gt;
  &lt;/manifest&gt;

  <p>I have created access key in Google APIs console(app is signed with a debug key, so I took SHA1 fingerprint from Eclipse Preferences->Android->Build->SHA1 fingerprint):

  and enabled only <code>Google Maps Android API v2</code> in <code>Services</code>:

  <p>I have no idea what is wrong. Can someone suggest me a solution?</p>
