title: Error on google maps
body: <p>I have this error: Google Maps Android API﹕ Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors)</p>
  
  <p>I must say that I have requested API key with the debug keystore and I do have the needed permissions. Here is my Manifest:</p>
