title: proguard doesnt ignore referenced libraries
body: <p>I use proguard, in proguard-project.txt, I have line for  ignoring referenced classes</p>
  
  <p>-dontwarn com.google.ads.**</p>
  
  <p>The log says:</p>
  
  <blockquote>
    <p>Warning: com.flurry.android.ab: can't find referenced class com.google.ads.InterstitialAd
    Warning: com.flurry.android.ab: can't find referenced class com.google.ads.InterstitialAd

    <p>You should check if you need to specify additional program jars.
