title: SmartWatch 2 Google Play Licensing
body: <p>I want to add Google Play Licensing to my smartwatch 2 app.</p>
  
  <p>I would like to know where is the best place to do the license check, since I do not want to do it when the user open the app on the watch since it may slow it down a lot.</p>
  
  <p>I would like to do it when the application is installed/registered, so I checked the onCreate() method of the Extension Service, which is called when the app is registered, but its also called when the app is launched on the watch.</p>
  
  <p>So, which is the best place?</p>
  
  <p>Thanks!!</p>
