Android in-app purchase possible bug: event.transaction.productIdentifier returning wrong ProductId.

scrapee.net · July 23, 2013, 9:08pm

Hello. I’m setting in app purchases for my android game, and I have seen same strange behaviors that looks to be some kind of bug.

In my game I have 3 buttons to allow users to buy “coins”

10.000 coins

25.000 coins

40.000 coins

The purchase works but when the callback function is called, event.transaction.productIdentifier get’s a wrong value, if it is not the first purchase of the user on the game.

Checking the logs generated by print("receipt: " … tostring(event.transaction.receipt)) I noticed, that the callback doesnt return just the last purchase, but it returns the last 10 purchases, and event.transaction.productIdentifier will return the first productId of the purchase list, and not the last one as it should.

This is how it looks:

receipt: {"nonce":2643703143987774433,"orders":[{"notificationId":"2120875375272880860","orderId":"12999763169054705758.1361928580590696","packageName":"net.game.name","productId":"10000coins.gamename","purchaseTime":1374610594000,"purchaseState":0,"purchaseToken":"xwxommmsyyomngprqwwpnmri"},{"notificationId":"-5087359489997754121","orderId":"12999763169054705758.1317937227200979","packageName":"net.game.name","productId":"10000coins.gamename","purchaseTime":1374610661000,"purchaseState":0,"purchaseToken":"ianelarmopftqqtxgsglusns"},{"notificationId":"-8809612338636471508","orderId":"12999763169054705758.1314428912834317","packageName":"net.game.name","productId":"25000coins.gamename","purchaseTime":1374610720000,"purchaseState":0,"purchaseToken":"dycnukexzquoluhattmehohq"},{"notificationId":"5244043765150494203","orderId":"12999763169054705758.1333974387111916","packageName":"net.game.name","productId":"10000coins.gamename","purchaseTime":1374610780000,"purchaseState":0,"purchaseToken":"grehrtyyzdhbyynshrzphwuo"},{"notificationId":"4634449798447896352","orderId":"12999763169054705758.1373356492242957","packageName":"net.game.name","productId":"10000coins.gamename","purchaseTime":1374610804000,"purchaseState":0,"purchaseToken":"tcmraordzttjesdekcpnamjk"},{"notificationId":"7217312897016584546","orderId":"12999763169054705758.1323725642031193","packageName":"net.game.name","productId":"10000coins.gamename","purchaseTime":1374610849000,"purchaseState":0,"purchaseToken":"vqlppfunuyomlabkyttduxni"},{"notificationId":"-7008381092592509620","orderId":"12999763169054705758.1339380580697182","packageName":"net.game.name","productId":"40000coins.gamename","purchaseTime":1374611152000,"purchaseState":0,"purchaseToken":"yjoqkohafzwppulznxwqlxlp"},{"notificationId":"-1090875021658922717","orderId":"12999763169054705758.1352732450791116","packageName":"net.game.name","productId":"10000coins.gamename","purchaseTime":1374611316000,"purchaseState":0,"purchaseToken":"uncliflpqdmqpvktvftwsnqx"},{"notificationId":"-939834656069426704","orderId":"12999763169054705758.1367275796937765","packageName":"net.game.name","productId":"25000coins.gamename","purchaseTime":1374612206000,"purchaseState":0,"purchaseToken":"pderxjndgwypezgxktuaacyg"},{"notificationId":"-2400558402594912129","orderId":"12999763169054705758.1329423969997620","packageName":"net.game.name","productId":"40000coins.gamename","purchaseTime":1374612352000,"purchaseState":0,"purchaseToken":"cbdwvbnuzcfiwsdanibtgxib"}]} I/Corona&nbsp; ( 3755): signature: VERYBIGSIGNATURECODE==

I’m almost sure this is a bug, so I’d like to hear something from the staff.

For iOs it gets the right responses.

Another bug that I noticed is that even my credit card being not accepted, the result was “purchased”

oh God… Now I discovered that the store.init callback listener is looping forever…

Can you post your code? Its sounds like you’re never calling the store.finishTransaction( transaction ) bits.

scrapee.net · July 24, 2013, 2:21am

I’m calling it. But it looks like it is not working, exactly like reported in this old post: http://forums.coronalabs.com/topic/29621-storefinishtransaction-is-not-working-properly/

Here is the essence of my callback code. All my purchases are consumable. I did some workarounds to avoid this problem, and for now it is working.

function transactionCallback(event) &nbsp; &nbsp;&nbsp;&nbsp;if(haspurchased==false) then --I setted this as a workaround for the problem, then after the purchase I change it to true, and avoid from running the callback twice or more. &nbsp; &nbsp; local infoString &nbsp; &nbsp; &nbsp; &nbsp; local function CompleteCoinTransaction(coinsbought) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;--save coins collected or anything i want &nbsp; &nbsp; &nbsp; &nbsp; end &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; if(device.isSimulator ==false) then --check if it is not simulator &nbsp;&nbsp;&nbsp;&nbsp;print("transactionCallback: Received event " .. tostring(event.name)) &nbsp;&nbsp;&nbsp;&nbsp;print("state: " .. tostring(event.transaction.state)) &nbsp;&nbsp;&nbsp;&nbsp;print("errorType: " .. tostring(event.transaction.errorType)) &nbsp;&nbsp;&nbsp;&nbsp;print("errorString: " .. tostring(event.transaction.errorString)) &nbsp;&nbsp;&nbsp;&nbsp;if event.transaction.state == "purchased" then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;infoString = "Transaction successful!" &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print(infoString) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print("receipt: " .. tostring(event.transaction.receipt)) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print("signature: " .. tostring(event.transaction.signature)) &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; --this is just another workaround, due to the problem if(device.isAndroid) then --if it is android device, get the last purchasedId from the event.transaction.receipt, otherwise it wont get the last purchase local jsonresponse=json.decode(event.transaction.receipt)&nbsp;

elseif event.transaction.state == “refunded” then

– Refunds notifications is only supported by the Google Android Marketplace.

– Apple’s app store does not support this.

– This is your opportunity to remove the refunded feature/product if you want.

just out of curiosity can I see your button code including the handler that starts this whole process off?

Remembering, that for ios it is working as it should. Testing the inapps using a test user, works as expected. The problem is presend just on android

rob · July 24, 2013, 11:14pm

The problem is related to the fact that widget.newButton’s generate multiple phases for when it’s first pressed and then when it’s released. These phases are just like touch events. There is a “began” phase and an “ended” phase. Please look at this block of code:

-- Function to handle button events local function handleButtonEvent( event ) &nbsp;&nbsp;&nbsp; local phase = event.phase &nbsp;&nbsp;&nbsp; if "ended" == phase then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print( "You pressed and released a button!" ) &nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp; return true end

If you do not put that if test in to check the phase, you will end up calling your code twice because this function gets called twice. Therefore you get duplicate calls to buy your items.

Hello. I did exactly what you said, even being almost sure it was not going to work, because I call the function to buy, on the “onRelease” of the widget button.

As I expected the callback looped forcing the app to crash, even calling the store.purchase, from inside the

local function BuyCoins(event) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if "ended" == event.phase then &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; store.purchase("item.to.buy") &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; end end

Please, consider the possibility that store.finishTransaction() is not working with the last build. I’m using now build 1129, the same problem also with 1128

rob · July 25, 2013, 2:08am

The current daily is 1170. Is there a reason you’re using a build older than the latest public build (1137)?

scrapee.net · July 25, 2013, 3:18am

Sorry. I got confused. I’m using the latest daily build. I just got confuse when copying the version number. I was not on the first page, of the daily build pages. I meant Im using now 1170 and the problem is also in 1168

Can you build and run the IAP sample app? Before I ask the Engineers, they are going to want to know if you’ve done that.

scrapee.net · July 23, 2013, 11:37pm

oh God… Now I discovered that the store.init callback listener is looping forever…

Can you post your code? Its sounds like you’re never calling the store.finishTransaction( transaction ) bits.

The problem is related to the fact that widget.newButton’s generate multiple phases for when it’s first pressed and then when it’s released. These phases are just like touch events. There is a “began” phase and an “ended” phase. Please look at this block of code:

-- Function to handle button events local function handleButtonEvent( event ) &nbsp;&nbsp;&nbsp; local phase = event.phase &nbsp;&nbsp;&nbsp; if "ended" == phase then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print( "You pressed and released a button!" ) &nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp; return true end

If you do not put that if test in to check the phase, you will end up calling your code twice because this function gets called twice. Therefore you get duplicate calls to buy your items.

Hello. I did exactly what you said, even being almost sure it was not going to work, because I call the function to buy, on the “onRelease” of the widget button.

As I expected the callback looped forcing the app to crash, even calling the store.purchase, from inside the

local function BuyCoins(event) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if "ended" == event.phase then &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; store.purchase("item.to.buy") &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; end end

Please, consider the possibility that store.finishTransaction() is not working with the last build. I’m using now build 1129, the same problem also with 1128

The current daily is 1170. Is there a reason you’re using a build older than the latest public build (1137)?

Sorry. I got confused. I’m using the latest daily build. I just got confuse when copying the version number. I was not on the first page, of the daily build pages. I meant Im using now 1170 and the problem is also in 1168
