title: Min3d doesn't show anything (in sample from min3d wiki)
body: <p>I'm trying to create a simple Android application using <a href="http://code.google.com/p/min3d" rel="nofollow">min3d library</a></p>
  
  <p>Previously I have downloaded apk file from market with examples of min3d library. Every example in this application works fine on real phone. It means phone has not problems with 3d. </p>
  
  <p>I have chekouted source code of min3d with examples and created simple Android application with single activity copypasted from examples:</p>
  
  <pre><code>import min3d.core.Object3dContainer;
  import min3d.core.RendererActivity;
  import min3d.objectPrimitives.Box;
  import min3d.vos.Light;
  
  public class ExampleMostMinimal extends RendererActivity {
      Object3dContainer _cube;
  
      public void initScene() 
      {
          scene.lights().add( new Light() );
          _cube = new Box(1,1,1, null, true,true,false);
          _cube.colorMaterialEnabled(false);
          scene.addChild(_cube);
      }
  
      @Override 
      public void updateScene() 
      {
          _cube.rotation().y++;
      }
  }
  </code></pre>
  
  <p>But when application launched it shows title bar and black screen. </p>
  
  <p>Please, help.</p>
