title: How can I implement Google Play Licensing for an Android app?
body: <p>I saw the stock Android-Developer licensing library <a href="http://developer.android.com/google/play/licensing/index.html">instructions</a>, but the overview seems to omit several key steps in the process and fails to fully explain how to get something working.</p>
  
  <p>Can someone provide an explicit set of operations that worked to get the licensing library set up on an Android app so it checks to ensure that a user has paid for an app in Google Play before allowing use?</p>
