title: How to turn off proguard completely?
body: <p>I have an Android application on which I don't want to do anything regarding optimization/obfuscation/etc.</p>
  
  <p>I deleted the (auto-generated) proguard configuration file (proguard.cfg) but I think my library projects' files are still being obfuscated, because in the crash reports I don't see the line numbers - <code>Unknown Source</code> is shown instead.</p>
  
  <p>How can I turn off proguard completely?</p>
  
  <p>Also, how can I validate that it was indeed turned off?</p>
