Restoring consumable

[gilamran]

Hi,
If a user purchased a consumable, and the app crushed after the success.
On restart, how do I "know" that the user did not get what he bought?

Is there a way to get all the consumables that the user purchased, but was not able to consume?
I know that when doing getProductsInfo, we get the products, but also a purchases Array, are these the unconsumed products?

Also, there's the restoreTransactions, will this function return all the unconsumed products?

Thanks
