title: Android market, tracking purchases to devices
body: <p>Is it possible to identify an Android device from which a particular Android Market order (ID provided) was filed? ANDROID_ID would do, for example.</p>
  
  <p>There's a <code>&lt;buyer-id&gt;</code> element in order notifications that "identifies the buyer uniquely to Google", but there's no info what's its relationship to Google ID, ANDROID_ID or anything of the like.</p>
  
  <p>Or on the contrary, given a paid app on device, is it possible to retrieve the order ID that the app was purchased with?</p>
