Hey I had worked on InApp Purchase recently and I've successfully integrated in my existing app and ready to make it live. Initially when i had started doing this I've downloaded google InApp Billing Example called "Trivial Drive" from here.

But it didn't help me much as it has lots of issues and bugs, So I've decided do it on my own from scratch using new v3 api which you can find here. This tutorial has clear explanation that would help you and also if you have time, see this youtube video where google employee had explained clearly how to integrate it.

Also if you want quick example, I've a sample app which you can download from here.

The following video also explains how to integrate InApp Purchase. Please go through it.
