title: Proguard not obfuscating in Android Studio
body: <p>I am trying to export signed apk, obfuscated with proguard. But after process, I can see my code and my class names in decompiler tool. Spent 1 day , but can't understand what I missed.</p>
  
  <p>In my gradle file I specified :</p>
  
  <pre><code>    buildTypes {
          release {
              apply plugin: 'maven'
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  </code></pre>
  
  <p>proguard-rules.pro is empty.
  Should I specify anything else to enable proguarding ? After decompilation</p>
