[android-developers] How restore transaction in In-App Billing (Android) work?

I tried to search about that problem, but didnt get many information.
I just know that:
- Restore in the first time user install app or when user reinstall
when they uninstall/wipe data.
- Restore transaction just apply for managed-product.
I tried to read Dungeon Example, there are few line of code about
restore transaction like: when to call restore request, when to get
restore respone... but i dont know:
- How to get return information? (like item id that user had bought
cause we need that id to ensure that user will not buy it again?)
