Android Question Google Play Billing - How to make use of this

[EstasPerplejo]

Hi all.
I could use some help on how to implement and use the Google Play Billing library.

I plan on putting an new app into the playstore that offers to purchase one or more in-game products.
One these purchasable items should turn the game from a limited version to a full version after it has been bought.

I know I need to add the play billing library in the manifest, but that's about it...

Now here a couple of question concerning in-app products :
Does the app need to be a paid app or can I include purchasable items in a free app?

Does anybody here in the community has an app or game in the playstore to see how it is done? A link perhaps...

What else do I need take care of in order to accomplish this. A little guideline would surely be appreciated.

Thanks guys
