title: Android - Google Map doesn't display
body: <p>Please excuse my bad English, I'm French !</p>
  
  <p>I've got a question about my Android App...
  I hava to integrate a google map, so I've followed a tutorial (from Google developper website), but when I when to try the Google Demo I've got a blank map ! Nothing is displayed and I've got this error :</p>
  
  <pre><code>06-17 14:34:29.067: E/Google Maps Android API(29152): Authorization failure.  Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.
  06-17 14:34:29.067: E/Google Maps Android API(29152): Ensure that the following correspond to what is in the API Console: Package Name: com.example.mapdemo, API Key: AIzaSyBWkgi7WlIhPRT8UQtxyIlz4yr9UZ3qE5c, Certificate Fingerprint: ADFDA5FBEEFC1C02BEFD197CD30B3A581327107D
  06-17 14:34:29.887: E/Google Maps Android API(29152): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).
  </code></pre>
  
  <p>I've have executed this command in order to get the SHA-1 :</p>
  
  <pre><code>C:\Program Files\Java\jdk1.7.0_21\bin&gt;keytool -list -alias androiddebugkey -keystore C:\Users\AZS\.android\debug.keystore -storepass android -keypass android -v
  </code></pre>
  
  <p>And the package name is : com.example.mapdemo</p>
  
  <p>I've activated Google Maps Android API v2 &amp; Google Maps API v2 into the service tab.</p>
  
  <p>But it doesn't work...</p>
  
  <p>Have you got an idea ?</p>
  
  <p>Thanks a lot !</p>
