title: Error in compile ShowcaseViewSample
body: <p>I downlaoded ShowcaseView Library from github and imported this on eclipse. I downloaded ActionBarSherlock-4.4.0 and imported it as well.</p>
  
  <p>I also added ShowcaseView Library and ActionBarSherlock-4.4.0 to a sample project and didn't get any error on this, but when I click on <code>run as android application</code>, after long time I get:</p>
  
  <p><code>Conversion to Dalvik format failed: Unable to execute dex: Java heap space</code></p>
  
  <p>and app doesn't run.</p>
  
  <p>Meanwhile I get this in the console:</p>
  
  <p><code>Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
  (org.ibex.nestedvm.util.Sort$1) that doesn't come with an
  associated EnclosingMethod attribute. This class was probably produced by a
  compiler that did not target the modern .class file format. The recommended
  solution is to recompile the class from source, using an up-to-date compiler
  and without specifying any "-target" type options. The consequence of ignoring
  this warning is that reflective operations on this class will incorrectly
  indicate that it is *not* an inner class.</code></p>
  
  <p>Please help me.</p>
