 <p>
   With the Preview, you'll get an early start on testing your apps,
   with enough time to make adjustments before the public platform release later
   in the year. We'll provide several updates to the Preview tools in the weeks
   ahead, so you can keep in sync with the latest changes as the platform moves
   toward launch.
 </p>

 <p>
   You can help us improve the platform by <a href=
   "https://code.google.com/p/android-developer-preview/">reporting issues</a>
   through our feedback channels. This is especially
   critical in the first month of the preview, when we’ll be giving priority to
   developer-reported issues and feedback.
