title: android dex library
body: <p>I've an Android application which use a lot of librairies (in jar files). 
  When I compile my application in dex file with the dex.bat tool, it's take a very long time because of the conversion of the jar libraries into dex format. 
  So, my question is : how can I link librairies in dex format to my application instead of linking jar librairies ?</p>
