My app will be distributed via Google Play in 2 versions. Lite version (free) and Full version (small charge).
The Lite version will be crippled in some way - otherwise same as full version.

Can anybody suggest a way of implementing an unlock code so that a few (very special) lite users can be given access to the functions of the full version without having to buy it via Google Play?

NB I am not attempting to avoid paying money to Google - the unlock code would be free.

The answer depends on how much you are worried from hackers. The main problem with a lite version that turns into a full version is that you will need to include the full functionality in the lite version. This means that a hacker may be able to remove the protection and turn it into a full version.

It also depends on how will you communicate with these users.
One simple solution is to send them the full APK by mail (will require them to allow installations from unknown sources).
