Stop my app from being updated(auto-update is disabled)
<p>Consider that user has my app with version 1 and auto update option is disabled/off. I have an upgrade in the market for my app(say version 2). 
User gets a notification saying, "updates available" and updates my app.
Now based on some requirement I need my app not be be upgraded to version 2.
Can this be done?</p>
