title: GooglePlayServicesUtil cannot be resolved
body: <p>Recent updation to <code>com.google.android.gms:play-services-ads:8.4.0</code> results in this error. This does not happen when <code>com.google.android.gms:play-services:8.4.0</code> is used, but it bloats the apk size significantly. Also to implement in-app billing, it is needed to check whether Google Play services are installed or not before starting a purchase.</p>
  
  <p>Is there a workaround for this?</p>
