How to customize android title bar in fragments?

Is there any way to add one time redeemable codes for a single Android title in Play (or any other major Android market)?

• I'd like to be able to create a paid Android application, then be able to sell a unique code at a physical location that would allow the downloading of just that one title from the store.  So, not a Play gift card, the code is just for one time use for a copy of one title.  Basically I'd like Play to manage the security and availability of the title, but I'd like to be able to sell it at a physical location.  Any ideas?

  I don't work for Google, but if you want them to provide the Play market and security for your app, you're going to have to let them take their cut of the sales. Google Play is their store; no one would let you use their store as a warehouse while you collect all the money yourself. Even free aps provide Google more data and a share of the ad revenue. If you want to go around Google altogether, Android phones all allow sideloading of apps. Host the apk on your own website, and sell access to that site with a card that has a unique username and password. You won't appear in the Play store though, which could limit your visibility.
