title: maps working with debug API key but not with release API key...?
body: <p>I have finished the development of my app which uses Google Maps. During the development/debug phase, I used a debug MD5 key and generated a debug Google Maps API key on Google website. Google Maps worked perfectly well on both emulator and device.</p>
  
  <p>Now, I want to release my app. I generated a release MD5 key and a release Google Maps API key.</p>
  
  <p>I copied/pasted this release API key in my xml map file:</p>
  
  <pre><code>&lt;com.google.android.maps.MapView
      [...]
      android:apiKey="xxxxxxx"
  /&gt;
  </code></pre>
  
  <p>But now, when I run the app on my device, I just get a gray grid instead of a map...</p>
  
  <p>I took care to put android:debuggable to false in my manifest:</p>
  
  <pre><code>&lt;application android:icon="@drawable/icon"
                      android:label="@string/app_name"
                      android:debuggable="false"
                      android:theme="@android:style/Theme.NoTitleBar"&gt;
  </code></pre>
  
  <p>Do you know what I can do to solve my issue ?</p>
  
  <p>Thanks !!!</p>
  
  <p>[EDIT] Perhaps the problem is due to the fact that I run the app on my device in debug mode and not in release mode ? If it is the issue, how to run my app in release mode on my device ?</p>
