Wanting to prevent someone from taking a snapshot
<p>I'm building a app for a business. In this app I'm wanting to place some exclusive coupons people can use at the store for having the app installed. Because its a free app, I'm going to have ads placed in the app. Wanting to keep the rev coming in, I don't want people to just take a snapshot of the coupons, and then delete the app... Is there a way to prevent them from doing this? Or is there a way I could have a VOID pop up on the snapshot of the coupon when they take the snapshot? </p>
