title: Requesting user to rate/review/comment on Android Market
body: <p>Is there a way I can request user for a rating/review/comment for the application from within the application (Activity).</p>
  <p>One option I can think is to create a link in the application to Android market where user can enter review/rating/comment. What I am looking is to allow the user to do this without leaving the application.</p>
  <p>Also, I need to find out if the user has already reviewed. (Which case, I may choose to change the link to 'Revise the review' instead of 'Add a review').</p>
  <p>Is this possible?</p>
  <p>Alternatively, if I redirect to the market page, is it possible to take the user straight to the review section (not top of page)</p>
