title: proguard-project.txt not found in android studio
body: <p>I am new to Android and Android Studio.</p>
  
  <p>During my learning I came across the Google Play Services for Ads and all. </p>
  
  <p>I tried to enable proguard in my project but reading the below link <strong><a href="http://developer.android.com/google/play-services/setup.html">proguard</a></strong>.</p>
  
  <p>The problem is that I am not able to find <strong>proguard-project.txt</strong> or <strong>proguard.cfg</strong> in my project structure...</p>
  
  <p>Instead there is a <strong>proguard-rules.txt</strong> in my project structure...</p>
  
  <p>How can I find these missing files and configure proguard in my project...</p>
  
  <p><strong>Please help</strong>...</p>
