Restore transaction inapp purchase android

问题:

How to do restore transaction in in-app billing purchase android. So far I have searched in all links. I didn't find exact infromation. I have used BillingHelper.restoreTransactionInformation(BillingSecurity.generateNonce()) but it returns nothing.
Can anyone help me to come out of this problem.

Any help would be appreciated.

The V3 of the api does not require anymore to restore the purchases. Can directly query for purchased items.

Please read the section Querying for Purchased Item of: http://developer.android.com/google/play/billing/billing_integrate.html
and the getPurchases() method description.
