IAPs - receiving receipts on my own dev account test purchases

tdprogramming · July 2013

Good evening/morning. Firstly, I'm sorry if this has been asked already. I've done some searches but not found anything.

I'm just submitting a game now. When testing the single IAP I have (an entitlement that just upgrades to all levels unlocked) I've had success processing a test payment for the SKU. However I also have a "Restore previous purchases" button which gets a list of receipts and in the complete handler for that does this:

public void OuyaGetReceiptsOnSuccess(List<OuyaSDK.Receipt> receipts)

{

m_receipts.Clear();

foreach (OuyaSDK.Receipt receipt in receipts)

{

m_receipts.Add(receipt);

if (receipt.getIdentifier() == m_products[0].getIdentifier())

{

// Only 1 product so we're unlocked

//... code to unlock full game goes here.

purchaseStatus = PURCHASE_COMPLETE;

}

if (purchaseStatus != PURCHASE_COMPLETE)

{

if (m_receipts.Count == 0)

{

myErrorString = "No receipts in array";

}

else

{

myErrorString = m_receipts[0].getIdentifier() + ", " + m_products[0].getIdentifier();

}

purchaseStatus = ERROR;

}

As you can see it's based on the IAP example from the ouya package. However, even when this function is called indicating a success, there are never any receipts in the list, even if I have already purchased the upgrade,

I was wondering if this is because the purchases are test purchases on my own account so won't generate receipts on the system? If this is the case then how should we test such restore functionality? I've submitted the game based on the above assumption, will hold back from publishing and fix if that's not the case.

Secondly, if someone tries to buy an entitlement a second time, will the Ouya system charge them again, or does it pick up that you've already bought this item (as with the Apple IAP system) and refuse to charge you again?

Many thanks for your help.

You can only purchase an entitlement once. Even if the user purchases it twice. Still you should be able to check receipts and not have to rely on the second purchase.

I'd recommend when you detect the receipt, add the unlock to the player prefs. And then on game start check the player prefs to see if the game is unlocked before you get receipts.

You only need to show the buy button if you don't detect the player pref or the receipt.

Many thanks for your quick reply Tim. This is the model I was hoping to follow, the problem is that I don't get any receipts returned by the API even after I've purchased something.

If I've called the getReceipts function and had a success returned to invoke the code above, and my Ouya dev account shows a receipt for the item, then surely there should at least be a list of receipts with a length > 0 in the above example? I'm getting a length of 0, so I'm wondering if there's an issue on the server side, or dev accounts that can buy goods free don't store a receipt in the same way, hence none get returned?

It's possible that you have a configuration mismatch.

You need to copy the signing key from the developer portal for your game into Assets\Plugins\Android\res\raw\key.der

You need to generate a keystore and always use the same keystore so the auto updater can work.

You need to enter your developer id from the developer portal into the OuyaGameObject.

You need a unique bundle id for your game: com.yourcompany.title

Howdy, Stranger!
