Coupon codes or promo codes on google play or anything?

I am a first time android developer and soon will be submitting an app. One of my plans to help sell this app is to use other people to tell their friends… those people would have a coupon code so their friends could save money.

The idea is for me to be able to track who got someone to buy the app using a coupon code and how many times.

This way I can give that person a cut of hte profits depending on how many people they themselves got to buy it.

The idea situation is create various coupon codes and track how many purchases were made with those coupon codes.

Is there any way to do that?

Not accurately since AFAIK Google doesn’t give up referer URLs from bought apps. You can naturally use your own redirect service to get some kind of estimates, but because you cannot know if redirected user bought anything, it is hard to reward people.
