Google Play services allow gradle to ignore proguard configuration

I’m working on the "Log in to Google" setting in my application. I used the official documentation for this.

So my configuration does not look like this:

Gradle top level file:

buildscript {
  repositories {
    jcenter()
    mavenCentral()
    maven { url 'https://maven.fabric.io/public' }
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:1.5.0'
    classpath 'io.fabric.tools:gradle:1.+'
    classpath 'com.google.gms:google-services:1.5.0'
  }
}

app.gradle file

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
   buildTypes {
      minifyEnabled true
      shrinkResources true
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
      signingConfig signingConfigs.release
  }
}

dependencies {
    // retrofit, twitter sdk, eventbus, support library, activeandroid
    // Google SignIn
    compile 'com.google.android.gms:play-services-auth:8.3.0'
}

And the problem is that the application does not start now with the exception that the ActiveAndroid classes are not found, and during the build I receive billions of messages (below). It seems that including google play services are ignoring my proguard rules. If I remove these dependencies, the application will work well and start without any errors.

Note: there were 25 classes trying to access annotations using reflection.
      You should consider keeping the annotation attributes
      (using '-keepattributes *Annotation*').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#attributes)
Note: there were 35 classes trying to access generic signatures using reflection.
      You should consider keeping the signature attributes
      (using '-keepattributes Signature').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#attributes)
Note: there were 6 classes trying to access enclosing classes using reflection.
      You should consider keeping the inner classes attributes
      (using '-keepattributes InnerClasses').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#attributes)
Note: there were 1 classes trying to access enclosing methods using reflection.
      You should consider keeping the enclosing method attributes
      (using '-keepattributes InnerClasses,EnclosingMethod').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#attributes)
Note: there were 24 unresolved dynamic references to classes or interfaces.
      You should check if you need to specify additional program jars.
      (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclass)
Note: there were 42 accesses to class members by means of introspection.
      You should consider explicitly keeping the mentioned class members
      (using '-keep' or '-keepclassmembers').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclassmember)
Note: you're ignoring all warnings!
