Restore Transaction Inapp Purchase Android

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.restoreTransaction

Solution 1:

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.
