I created the app 3dweapons for Android about 2 1/2 years ago. (http://www.3dweapons.net) The free version was downloaded >1.7 million times. The paid version around 8k times.
I added adds from multiple sources (mopub, admob etc) and in app purchases.
For the paid app: In the top months (2 years ago) I made around 800 euro. But it dropped to 90 euro per month currently.
For in app purchases: I am making 30 euro per month currently.
For ads: Making about 200 euro per month currently.
You are referring to the pirated versions of my app?
Actually i dont have hard figures.
Initially I was not aware of pirated versions. I even had my app translated to chinese because I thought it would be a huge market. But after I did that, i noticed Google Play is not active there, and all paid apps are free in china.... Pirated versions.
I tried to prevent pirated versions of my app by performing code obfuscation, but probably it was still easy to crack.
