title: Android: Signed Apk file does not include external library and throws "java.lang.ExceptionInInitializerError"
body: <p>I recently signed an apk file for release on Google Play and when I downloaded the application on Google Play and installed it, it would throw java.lang.ExceptionInInitializerError. </p>
  
  <p>My co-worker and I are suspecting that the library was not being added to our signed apk file.  </p>
  
  <p>We added our additional library to our project by adding it to our build path for the project.</p>
  
  <p>Also, the library we are trying to add to our project is ActionBarSherlock.</p>
  
  <p>Is there a reason why our library is not being included in our signed apk file, because we notice the file size for our signed apk is alot smaller than our unsigned version?</p>
  
  <p>Can anyone point us in the right direction in signing our apk file correctly so that it includes the library we added into our build path?</p>
