title: google-services.json for different productFlavors

  <p>I'm implementing the new Google Cloud Messaging following the guides from the Google Developers page <a href="https://developers.google.com/cloud-messaging/android/client" rel="noreferrer">here</a></p>
  
  <p>I've successfully run and test it. But my problem now is I have different product flavors with different applicationId/packageName and different Google Cloud Messaging Project Id. The <code>google-services.json</code> have to be put at the <code>/app/google-services.json</code> not the flavors folder.</p>
  
  <p>Is there any way to make the <code>google-services.json</code> config different for many flavors?</p>
