Android In-app Billing Restore_transaction Usage

Is there any example available on how to use RESTORE_TRANSACTIONS request to restore an In-app product purchase information? I came up with this code, but it always returns 0, so i

Solution 1:

I used this method:

publicstaticvoidrestoreTransactionInformation(Long nonce) 
    {
        if (amIDead()) 
        {
            return;
        }
        Log.i(TAG, "confirmTransaction()");
        Bundlerequest= makeRequestBundle("RESTORE_TRANSACTIONS");
        // The REQUEST_NONCE key contains a cryptographically secure nonce (number used once) that you must generate
        request.putLong("NONCE", nonce);
        try 
        {
            Bundleresponse= mService.sendBillingRequest(request);

            //The REQUEST_ID key provides you with a unique request identifier for the requestLongrequestIndentifier= (Long) response.get("REQUEST_ID");
            Log.i(TAG, "current request is:" + requestIndentifier);

            //The RESPONSE_CODE key provides you with the status of the requestIntegerresponseCodeIndex= (Integer) response.get("RESPONSE_CODE");
            C.ResponseCoderesponseCode= C.ResponseCode.valueOf(responseCodeIndex);
            Log.i(TAG, "RESTORE_TRANSACTIONS Sync Response code: "+responseCode.toString());
        } 
        catch (RemoteException e) 
        {
            Log.e(TAG, "Failed, internet error maybe", e);
            Log.e(TAG, "Billing supported: " + isBillingSupported());
        }
    }

, The call is as follows:

BillingHelper.restoreTransactionInformation(BillingSecurity.generateNonce());
