title: Proguard does not remove my logs
body: <p>I want to clear my project from logs, when releasing.
  But i'm trying to use proguard and have zero result:
  my project settings : </p>
  
  <pre><code>proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
  
  # Project target.
  target=android-19
  android.library.reference.1=..\\google-play-services_lib
  </code></pre>
  
  <p>And my proguard-properties</p>
  
  <pre><code>   -optimizationpasses 5
  -dontusemixedcaseclassnames
  -dontskipnonpubliclibraryclasses
  -dontpreverify
  -keepattributes LineNumberTable
  -verbose
  -optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
  
  -renamesourcefileattribute SourceFile
  -keepattributes SourceFile,LineNumberTable
  
  #To remove debug logs:
  -assumenosideeffects class android.util.Log {
      public static *** d(...);
      public static *** v(...);
      public static *** w(...);
      public static *** i(...);
  }
  
  
  -keep class android.support.v4.** { *; }

  -keepclassmembers class * { 
      public void onClickUpdate(android.view.View);
