title: Alternative to dex2jar and jd-GUI?
body: <p>it seems that either <a href="http://code.google.com/p/dex2jar/">dex2jar</a> and/or <a href="http://java.decompiler.free.fr/?q=jdgui">jd-GUI</a> gives bad de-obfuscation even for the simplest code of if-else condition (they show a <code>while(true)</code> loop which has a <code>return;</code> on its first line .</p>
  
  <p>are there any other freeware apps that do the same work of de-obfuscation? maybe something that can also use the mapping file of proguard ?</p>
