title: No matching client found for package name "...." with different buildvariant
body: <p>I want o implement push notification.
  I added to project level:</p>
  
  <pre><code>dependencies {
          classpath 'com.android.tools.build:gradle:2.2.2'
          classpath 'com.google.gms:google-services:3.0.0'
  }
  </code></pre>
  
  <p>and to app level:(at the bottom of the file)</p>
  
  <pre><code>   ....
     compile 'com.squareup.okhttp3:okhttp:3.3.0'
  }
  apply plugin: 'com.google.gms.google-services'
  </code></pre>
  
  <p>Then I added google-services.json file to project in app level</p>
  
  <p>But, when I syncro gradle, it launch the error:</p>
  
  <pre><code>No matching client found for package name "...." 
  </code></pre>
  
  <p>In gradle I have 2 different build variants , and look like:</p>
  
  <p><a href="https://i.stack.imgur.com/fGVzC.png" rel="noreferrer"><img src="https://i.stack.imgur.com/fGVzC.png" alt="enter image description here"></a></p>
  
  <p>Manifest:</p>
  
  <pre><code>&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
            package="es.xxx.awsomeapp"&gt;
  
      &lt;uses-permission android:name="android.permission.INTERNET"/&gt;
  
      &lt;application
          android:name=".realm.XXXXXX"
          android:allowBackup="true"
          android:icon="@mipmap/ic_launcher_chv"
          android:label="@string/app_name"
          android:supportsRtl="true"
          android:theme="@style/AppTheme"&gt;
          &lt;activity
  </code></pre>
  
  <p>And finally the gradle:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  apply plugin: 'realm-android'
