title: AndEngine error on loading library
body: <p>I have a problem while running the examples from andengine. The error I'm getting is at this line:</p>
  
  <pre><code>System.loadLibrary( "andenginephysicsbox2dextension" );
  </code></pre>
  
  <p>Couldn't load andenginephysics2dextension. Find library returned null. I noticed other people kept having this problem but no solution was proposed.</p>
  
  <p>Any help is welcomed! Thanks.</p>
