title: AdvertisingIdClient without google play services
body: <p>We ran into a problem and cannot add Google Play Services lib to our application.</p>
  
  <p>The problem is that the lib introduces 24,000 methods and a single dex can only contain 65536 methods. </p>
  
  <p>Is there a way to get the Google Advertising ID without a reference to Google Play Services?</p>
