title: Proguard error android, unable to access jar file
body: <p>This is the first time I am using progurad and getting the following error on exporting signed apk.</p>
  
  <blockquote>
    <p>Error: Unable to access jarfile ..\lib\proguard.jar</p>
  </blockquote>
  
  <p>I uncommented the proguard.config= line</p>
  
  <pre><code>   # To enable ProGuard to shrink and obfuscate your code, uncomment this (available   properties: sdk.dir, user.home):
     proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
  </code></pre>
  
  <p>But there still seems to be some issue.
  What is needed to fix it.</p>
