title: GdxRuntimeException on Android: couldn't load shared library 'gdx' for target
body: <p>I've developed a Libgdx application and tested it on my Samsung Galaxy S3(4.1.2) where it is working great.  I tried to test it on a Galaxy Grand(4.1.2) but it failed.  In the logcat, I found the following:</p>
  
  <pre><code>caused by com.badlogic.gdx.utils.GdxRuntimeException couldn't load shared library 'gdx' for target: Linux, 32-bit
  </code></pre>
  
  <p>This happened when changing the device only so any idea what is the cause?!</p>
  
  <p>The complete logcat:</p>
