title: Proguard in Android Studio are not removing logging
body: <p>Using Android Studio 1.2 beta, Proguard 4.7, I'm not able to optimize (remove) <strong>Log.d</strong>. </p>
  
  <p>Using the tools <strong>d2j-dex2jar</strong> and <strong>jd-gui</strong> I can see that all the Log.d remains in the apk.</p>
  
  <p>Any wise comments on this problem?</p>
  
  <p>The <strong>proguard-rules.pro</strong> are used because the <strong>-dontwarn</strong> are working.</p>
  
  <p>My <strong>proguard-rules.pro</strong>:</p>
  
  <pre><code>-assumenosideeffects class android.util.Log {
      public static *** v(...);
      public static *** i(...);
      public static *** w(...);
      public static *** d(...);
      public static *** e(...);
  }
  
  -dontwarn com.google.common.**
  -dontwarn javax.annotation.**
  -dontwarn javax.inject.**
  -dontwarn sun.misc.Unsafe
  -dontwarn org.joda.time.**
  </code></pre>
