Android paid app FLOSS?

hi /prog/
I'm planning dev apps for android market. I'm a FLOSS soft. user/hobbyist developer, in this case I want to make some $ (I can't eat freedom philosophy), my dilemma is if I want to earn some money I have not to release these apps as FLOSS, because I give up many of my rights, I only can earn money with distribution (as many of the future buyers of the app!!!).
In this case FLOSS doesn't works?
The only way is not to open source, proprietary software with EULA?

Protip: nobody gives a fuck about your application's source. So if you're going to do something which could be used by someone apart yourself, separate that functionality as a library and license it with a BSD license.
