title: Android: proGuard tutorial to specify exclusion and inclusion from obfuscation
body: <p>I like to know if there's a cmprehensive tutorial on using proGuard for Android projects?</p>
  
  <p>Particularly, I like to learn how to specify which class to exclude (for all include mode), include (for all exclude mode) for obfuscation and also if I can exclude jar libraries and library project and other dependencies to exclude from proGuard obfuscation.</p>
  
  <p>Basically I like learn from some resources to get some practical fine grain customization of proGuard for use with Eclipse Android development.</p>
  
  <p>Thanks in advance.</p>
