  <p>I have no idea what could be causing this because the same version is working fine on my own phone using Android 4.0.4.</p>
  
  <p>Is there some issues with ABS and older version of the Android OS?</p>
  
  <p>I have decalred my min and target versions as follows:</p>
  
  <pre><code>&lt;uses-sdk android:targetSdkVersion="15" android:minSdkVersion="7"/&gt;
  </code></pre>
  
  <p>Any help would be greatly appreciated.</p>
