title: google play services not supported for Maps
body: <p>I'm developing an app on a PCB board wich has installed some kind of custom android v2.3.7. </p>
  
  <p>I need to run the GoogleMaps. I've done all that is supposed that must be done (created a key, imported google-play-services_lib, downloaded GooglePlayServices from SDk...) but when runing it, shows the next message:</p>
  
  <pre><code>Google Play services, which some of your applications rely on, 
  is not supported by your device. Please contact the manufacturer for assistance.
  </code></pre>
  
  <p>So, what must I do to make GoogleMaps running?</p>
  
  <p><strong>UPDATE--</strong></p>
  
  <p>Manifest file:</p>
  
  <pre><code>&lt;manifest
      ...
  
      &lt;meta-data
      android:name="com.google.android.maps.v2.API_KEY"
      android:value="(key)" /&gt;
      ...
  
      &lt;application
      ...
  
          &lt;meta-data 
          android:name="com.google.android.gms.version" 
          android:value="@integer/google_play_services_version" /&gt;
      &lt;/application&gt;
  </code></pre>
