title: Android Google MapView shows only empty tiles
body: <p>I'm tying to develop a simple app that shows a map.</p>
  
  <p>I obtained the debug.keystore API-Key and triple checked it for correctness.<br>
  I also exported the project as apk and used a custom keystore with associated API-Key.</p>
  
  <p>I have the following permissions set:</p>
  
  <pre><code>&lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.INTERNET" /&gt;
  </code></pre>
  
  <p>But on my devices and in the emulator are still only empty tiles showing.</p>

  <p>Theese exceptions repeat rapidly.</p>
  
  <p>Proxy issues or internet problems are not present. The map application works.</p>
  
  <p>maybe somebody can help.</p>
