title: How to launch the Google Play intent in 'Give Feedback' mode on Android?
body: <p>I have just written a game for the <a href="http://en.wikipedia.org/wiki/Google_Play" rel="nofollow noreferrer">Google Play Store</a> and would like to remind my customers to leave feedback on the market for the application (especially the demo version). Is there any way to launch the market intent in a mode that will take the user to the feedback / comments section of the page?</p>
  
  <p>I already use this approach for linking my demo to the paid application... </p>
  
  <pre><code>Intent goToMarket = null;
  goToMarket = new Intent(
                     Intent.ACTION_VIEW,
                     Uri.parse("market://details?id=com.paulmaidment.games.flagsoftheworld"));
  startActivity(goToMarket);
  </code></pre>
  
  <p>Is there a best practice?</p>
  
  <p>Additionally, is there any way to track referrals from my demo application so that I can try to calculate some kind of a conversion rate? (that is, how effective the demo application is at generating sales.)</p>
