Unity IAP Store Guides - Amazon, Apple, Google Play, Windows

Is that the way to go? But what do I need the CrossPlattform Validator for then?

 

@kogen take a trace using adb to see what is happening on the device, likely an exception.

@LotusBlack receipt validation is not automatic; Unity IAP puts each receipt on each product according to the information it gets back from Google Play. You need to use the validator to determine if those receipts are genuine.

 

I see, .hasReceipt only states that there IS a receipt then, not that it is validated, thanks for the clarification @Banderous.

 

Hello again,

I can feel we are almost done here, there is just one thing I cannot explain, when it comes to retrieving a product. On iOS I implemented the payment process and everything is fine, realized, that the app "forgets" the item, after I restart, and implemented a "retrieving" function. Which then works fine too. But now comes the headache:

I set up everything again, with a new test user and started the app.

Code (CSharp):

1.     public void OnInitialized(IStoreController controller, IExtensionProvider extensions)
2.     {
3.         m_StoreController = controller;
4.         m_StoreExtensionProvider = extensions;
5.        
6.         this.retrievePurchasedItems(); // after initializing retrieved possibly bought products
7.     }

(and the retrieving function)

Code (CSharp):

1.     private void retrievePurchasedItems()
2.     {
3.         if (Application.platform == RuntimePlatform.IPhonePlayer ||
4.             Application.platform == RuntimePlatform.OSXPlayer)
5.         {
6.             var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
7.             var appleConfig = builder.Configure<IAppleConfiguration>();
8.             this.transform.FindChild("TextDebug").GetComponent<Text>().text = "retrieving 1";
9.             var receiptData = System.Convert.FromBase64String(appleConfig.appReceipt);
10.             this.transform.FindChild("TextDebug").GetComponent<Text>().text = "retrieving 2";
11.             try
12.             {
13.                 AppleReceipt receipt = new AppleValidator(AppleTangle.Data()).Validate(receiptData);
14.                 this.transform.FindChild("TextDebug").GetComponent<Text>().text = "retrieving 3";
15.                 this._checkAppleProducts(receipt.inAppPurchaseReceipts); // this is the function where each product is handled if it exists (could be retrieved).
16.                 this.transform.FindChild("TextDebug").GetComponent<Text>().text = "retrieving 4";
17.             }
18.             catch (Exception e) // change this to "IAPSecurityExcepetion and test again later
19.             {
20.                 this.transform.FindChild("TextDebug").GetComponent<Text>().text = "Nothing retrieved";
21.             }
22.         }
23.     }

Obviously nothing was retrieved since the user has not bought anything, so the app starts telling me "Nothing retrieved" which is correct.
I click on "buy" the item is bought BUT the ProcessPurchase method is not called. The event is not handled as process failed either.

Code (CSharp):

1.     public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args)
2.     {
3.         this.transform.FindChild("TextDebug").GetComponent<Text>().text = "bought";
4. }

Now when I restart my app the bought item is there (since the retrieving function works).

If I comment the retrieving function, it works like I can buy but not retrieve the products that have been bought at start up. I thought that the function may crash the app silently that's why I put in a general Try-Catch-Exception block, and obviously the function is executed completely. Cause it says "Nothing retrieved". To me this really does not make any sense.
My last gues is that I may have to initialize "this.retrievePurchasedItems()" before setting the m_Controller variables in the Initialize function since there might be going on something asynchronally?

Hope you can help me

Best kogen

 

Hey Kogen,

I believe all those builder methods are supposed to be called before you call UnityPurchasing.Initialize, so even before your OnInitialize callback happens!

 

Unity's amazing new receipt verification !

I just had a hell of a time finding NicholasAR's and Banderous's link to the new receipt verification, here it is:

and here's the link!

Unity's amazing new built-in
receipt validation and parsing library:

https://docs.google.com/document/d/1dJzeoGPeUIUetvFCulsvRz1TwRNOcJzwTDVf23gk8Rg/edit


Hope it saves someone some searching!!!

 

Here's our current code for Unity IAP,

First a base class. The only thing you have to personalise here is put in your actual store product codes around line 67.

This keeps all the IAP code together and abstracts out your local code which (a) literally pays out the IAP and (b) handles interface issues.

Note the four virtual classes.

So you don't have to do anything to the above script. Copy and paste!

Then you have your own derive. It has four simple calls which abstracts out everything about handing purchases in your own game...

43.     {
44.     //... your routines to, for example, save any local data (securely)
45.     }
46.  
47.   ///////////////////////////////////////////////////////////////////////////////////////
48.  
49.   // the final two classes to override...
50.   // in the example, we're expected to have a "WaitPanel"
51.   // which is a script on a UIPanel (perhaps showing a waiting animation)
52.  
53.   protected override void WaitShow()
54.     {
55.     WaitPanel w = Object.FindObjectOfType<WaitPanel>();
56.     // ie, in the present scene whatever that is.
57.     if (w == null) { Debug.Log("drastic woe, give up"); return; }
58.     w.Show = true;
59.     }
60.   protected override void WaitHide()
61.     {
62.     WaitPanel w = Object.FindObjectOfType<WaitPanel>();
63.     // ie, in the present scene whatever that is.
64.     if (w == null) { Debug.Log("drastic woe, give up"); return; }
65.     w.Show = false;
66.     }
67.  
68.   }
69.  
70.  

Of course, your Iap component would just sit on a GameObject likely in your preload scene with DontDestroyOnLoad.

To purchase from anywhere is simply .iap.Purchase( "BAGOFCOINS" ); and that's it.

In the example of how UI is handled (you can do it any way you want in the derive) you just need a "WaitPanel" script (probably on a UI panel) in every scene, which will sit on top and block all.

So, this script completely abstracts out the Unity IAP layer and you only need to write the functions of the four overrides for your game.

Two of the functions literally payout the purchases (this could be as simple as using secure preferences with Anti-Cheat Toolkit) and the other two just show/hide some sort of modal "wait for store!" panel which blocks all other interface.

 

BTW for anyone searching for the namespace for CrossPlatformValidator, it's

using UnityEngine.Purchasing.Security;

it's undocumented but you can see it in one of the "tangle" files, for instance.

Note that in this thread,

http://forum.unity3d.com/threads/so...enceexception-when-validating-receipt.393161/

user mh114 reports stripping issues when using with Android, hope it helps someone.

 

And here's a basic way to do more receipt verification, particularly for ios store...this will combat the most common receipt cheating. (I mean beyond the fact that Unity already awesomely check all the hashes, etc.)

In IapBase above there is PurchaseSUCCESSFUL() , only that routine need be changed...

The basic idea is you look through all the receipts, find the relevant one, and check it has not been used on the device already.

Code (CSharp):

1. private void PurchaseSUCCESSFUL(Product pp)
2.   {
3.   Debug.Log("IAP    PurchaseSUCCESSFUL .... next up verify");
4.  
5.   // transaction verification right here using pp.receipt
6.  
7.   var validator = new CrossPlatformValidator(
8.     GooglePlayTangle.Data(),
9.     AppleTangle.Data(),
10.     Application.bundleIdentifier);
11.  
12.   try
13.     {
14.     IPurchaseReceipt[] result = validator.Validate(pp.receipt);
15.     Debug.Log("IAP    Receipt is valid...");
16.  
17.    // in the Android case, we are done
18.      
19.    bool androidCaseHenceDone = false;
20.    #if UNITY_ANDROID
21.    androidCaseHenceDone = true;
22.    #endif
23.    if (androidCaseHenceDone)
24.       {
25.      Debug.Log("ANDROID ... no need for further checking.");
26.      PurchaseVERIFIED(pp);
27.      return;
28.      }
29.  
30.   // in the iOS case...........
31.   // and knowing (cross fingers Unity) that the product was meant to be
32.   // one of these: pp.definition.storeSpecificId
33.   // and that it might be one of these pp.definition.type == ProductType.Consumable
34.     string findThese = pp.definition.storeSpecificId;
35.  
36.     Debug.Log("IAP    looking through receipts for this one ... " +findThese);

Then in PurchaseProcessingResult() you should make this mod, to self-test...

Code (CSharp):

1. public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args)
2.   {
3.   Product pp;
4.   pp = args.purchasedProduct;
5.   Debug.Log("IAP    calledback from store to ProcessPurchase! --> " +pp.definition.id);
6.   Debug.Log("IAP    being careful to use the store-specific for verification: " +pp.definition.storeSpecificId);
7.   PurchaseSUCCESSFUL( pp );
8.   StartCoroutine(_DeliberatelyRepost(pp));
9.   return PurchaseProcessingResult.Complete;
10.   }
11.  
12. private IEnumerator _DeliberatelyRepost(Product pp)
13.   {
14.   // to ensure that your own security is working reasonably well
15.   // deliberately again call "Purchase SUCCESSFUL" a couple of times,
16.   // it should be that your verification system rejects the duplicates.
17.  
18.   yield return new WaitForSeconds(3f);
19.   PurchaseSUCCESSFUL( pp );
20.   yield return new WaitForSeconds(3f);
21.   PurchaseSUCCESSFUL( pp );
22.   }

Confusion about PRICE of using Unity Analytics / IAP services

Hey @Banderous and @nicholasr ...

I'm completely confused about how much it costs to use Unity's Analytics/IAP services. Are they plain free like Parse was? What's the deal? Are they free for now, free with a limit, or ?

 

Hey @Fattie,

Unity Analytics and IAP are free services! We did announce our paid tiers of Analytics recently at GDC, which give you higher limits for things like the amount of data you can download from Raw Data Export and Analysis Points. I cannot really give you any more information about when these paid tiers will become available but there will always be a free tier of Analytics!

 

@kogen if your code is throwing an exception you should log the exception details to see what is causing it.

 

I was following the IAP Unity tutorial, made my version for android.
I was struggling to get it working. I fixed it with adding the following but i couldnot find that in the tutorial, should this part not be added to the tutorial?

Can you explain why I had to add the following in my purchase script?
builder.Configure<IGooglePlayConfiguration>().SetPublicKey("my public key that I have in developer console");
I thought it was enough to add this public key in unity services in the dashboard place. But it seems not to work, in my case it doesnot (or I do somehting wrong ).

With adding above in my script it was finally working.

 

hi @Banderous and @nicholasr

"~/Desktop/691/Libraries/Plugins/UnityPurchasing/iOS/UnityPurchasing.m:106:62: 'transactionReceipt' is deprecated: first deprecated in iOS 7.0 - Use -[NSBundle appStoreReceiptURL]"

what's up with that! ignoring won't help, I'll keep posting it

 

IGooglePlayConfiguration is obsolete now that the receipt validation library is included. You do not need to set your Google Play public key via IGooglePlayConfiguration, that was always optional.

 

@Fattie

Code (CSharp):

1. ConfigurationBuilder builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
2. builder.AddProduct(myNewProduct, ProductType.NonConsumable, new IDs(){{myNewProductGoogle, GooglePlay.Name}});
3. builder.Configure<IGooglePlayConfiguration>().SetPublicKey("MIIB..............");
4.             UnityPurchasing.Initialize(this, builder);

this last part with IGooglePlayConfiguration did it for me that I get a connection to the google play part en get the popup for buying myproduct.

@Banderous I do not understand what you mean with receipt validation library is included Maybe I have to google it somewhere? Why is this not updated in the tutorial for IAP within Android, it is crucial for it getting working.

 

Android - when to Initialize issue?

@Banderous and @nicholasr dudes..

Definitely a couple folks have reported having trouble calling initialize in the google play store case.

Do you think we should just immediately call initialize when the app opens?

Or should we wait a few seconds?

Or should we keep trying it every few seconds?

Any thoughts on this?

 

@MarsGus you don't have to set your google play public key to use Unity IAP. Receipt validation is not a requirement of using Unity IAP, but it is documented here.

@Fattie what specific initialisation problem are you having? You should initialise Unity IAP only once as soon as possible. You should never attempt to reinitialise it.

 

@MarsGus regarding doing this:

Code (CSharp):

1. builder.Configure<IGooglePlayConfiguration>().SetPublicKey("MIIB..............");
2.             UnityPurchasing.Initialize(this, builder);

FYI we tested very carefully and we found indeed you DO NOT have to do that. It does work perfectly without it. (The system appears to already know your ID from where you enter it.) It must have been some other problem you were having.

@Banderous "You should initialise Unity IAP only once as soon as possible...." thanks for that clarification, good to know.

 

@Fattie that is interesting I will try working without (when I have time) it and test if i can also do it without.
Thanks for the information because I currently also have some kind of same problem with gathering metadata (localized price). In the editor it works and I retrieve the dummy testdata. But on my android device it does not work. Looks like some kind of same mistake.

Is it possible that building not always goes well if you are not running unity as an administrator on your laptop?

 

hi @MarsGus be sure to note THIS important tip! http://stackoverflow.com/a/36453606/294884

i believe regarding being an administrator on your windows laptop: makes no difference.

 

var validator = new CrossPlatformValidator(GooglePlayTangle.Data(), AppleTangle.Data(), Application.bundleIdentifier);

GooglePlayTangle.Data() and AppleTangle.Data() do not exist in the current context.Why?

 

You need to obfuscate your secrets to create them.

 

sorry for that but i m trying for 4 days but my iaps not working on android device when i click purchase button nothing happens...


in unity editor when i hit play and click purchase it show it is working

i check product id both are same in script and google iap

any idea is i m missing something?

or probably thats a bug?

thats the code i m using
made a button which calls buyconusmable function from the script.
Google Ids is same
"com.unity3d.test.services.purchasing.consumable"
and it is active in IAP product list in category of merged product

i check every thing now please tell me what else i can try!!!!!!!!!!!

 

It is not about your code, it is about the way your products are configured on each store's publisher dashboard. Follow the exact steps in the guide, including publishing as an alpha/beta.

 

hye i tracked down the main issue

that type of issue i m also facing with every plugin

thats the error

AndroidJavaException: java.lang.ClassNotFoundException: com.unity.purchasing.googleplay.GooglePlayPurchasing
java.lang.ClassNotFoundException: com.unity.purchasing.googleplay.GooglePlayPurchasing

i think its a bug in unity 5.3.4

 

HI @Cutier73098,

Sorry you're having this issue! Is this forum thread the same error as the one you're getting? If so, try this workaround described at the bottom of that thread.

 

Not sure if this is the best place or in Cloud services to post this, but I'm looking to release my game on GooglePlay and on Amazon and I'm very happy to see Amazon store is now supported by Unity IAP. I'm wondering how I can build my game on the cloud for both Amazon and Google in the cleanest possible way? For anything else that has required a split of the two platforms, I have created my own defines called UNITY_GOOGLEPLAY or UNITY_AMAZON to set the switch and then I've been able to configure those within the cloud and off we go, but I see in the Window menu there is a control to specify the target that then writes to a file.

Do you have a suggestion to build both types from the same source control repo?

 

You can use the static editor method UnityEngine.Purchasing.UnityPurchasingEditor.TargetAndroidStore() from a build script to switch android stores.

 

Cool - thanks for that - I'll give it a go.

 

it's magic you guys even added Amazon IAP

 

Hello guys. I'm building a test app on Unity for Amazon and I get this error OnInitializeFailed InitializationFailureReason: NoProductsAvailable when calling UnityPurchase.Initialize. I have checked and the JSON is configured properly with the name of the product. I'm using a Fire 7 (2015)
There is also another minor problem when I try to set manually the store by using UnityEngine.Purchasing.UnityPurchasingEditor.TargetAndroidStore(), the editor gives me the following error The type or namespace name `UnityPurchasingEditor' does not exist in the namespace `UnityEngine.Purchasing'. even thought I didn't get any error when compiling on visual studio. I'm using Unity 5.3.4f1.

The code is:

Code (CSharp):

1.  public void InitializePurchasing()
2.     {
3.         // If we have already connected to Purchasing ...
4.         if (IsInitialized())
5.         {
6.             // ... we are done here.
7.             return;
8.         }
9.  
10.         // Create a builder, first passing in a suite of Unity provided stores.
11.         var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
12.  
13.         // Add a product to sell / restore by way of its identifier, associating the general identifier with its store-specific identifiers.
14.         builder.AddProduct("package_of_coins", ProductType.Consumable);
15.      
16.         builder.Configure<IAmazonConfiguration>().WriteSandboxJSON(builder.products);
17.  
18.         UnityPurchasing.Initialize(this, builder);
19.     }

Update: I have update to Unity 5.4 and it supports now InApp for Amazon but when I deploy a really basic project (One scene and one script) for testing the InApp purchases I get the following errors (the project just opens to a black screen and closes in less than one second):
-Still not able to use UnityEngine.Purchasing.UnityPurchasingEditor.TargetAndroidStore (Same error than before)
-OpenGL error:

Update 2: The openGL bug is already reported for the beta version of Unity 5.4 it will be fixed in further releases and it is only happening to some Android devices (including my Fire 7)

Thanks!

 

Re: UnityPurchasingEditor have you updated to the latest version of Unity IAP? You can download and install the latest version by clicking 'import' in the IAP cloud service window.

 

I have this "InitializationFailureReason.PurchasingUnavailable" when start android app.
And link beta test is show:
Offers in-app purchases
x This app is incompatible with your device.

What happen in my case.

Thx.
Saksit.

 

"*NOTE: IL2CPP Windows builds using Unity IAP are not supported. Until support for Unity IAP with Windows IL2CPP is completed, using IL2CPP on Windows with Unity IAP will generate a compilation error."

Is there any estimative to IL2CPP support? We will get it on time for final 5.4?

Code (csharp):

1.  
2. Windows.LicenseInformation.isOnAppTrial
3.  

isOnAppTrial is also not supported on IL2CPP? I'm getting a crash when I try to use this.

 

@mankjon google play states that the app is incompatible with your device?
@Wagenheimer IL2CPP Windows plugin support will not make 5.4, but should be in 5.5.

 

Yes, app is incompatible with my device.
my Android phone is WIKO HIGHWAY.
Android version : 4.2.2
I look "Supported devices" at google play this model support.
I can install apk But, I can't test IAP.

Why?

Thank you.
Saksit

 

I suggest you raise it with Google, Unity IAP can only tell you that purchasing is unavailable. It may be related to your device or your google account, or both.

 

Hello , I do't understand the Restore Purchases.

Code (CSharp):

1.  
2. var apple = m_StoreExtensionProvider.GetExtension<IAppleExtensions>();
3.             // Begin the asynchronous process of restoring purchases. Expect a confirmation response in the Action<bool> below, and ProcessPurchase if there are previously purchased products to restore.
4.             apple.RestoreTransactions((result) => {
5.                 // The first phase of restoration. If no more responses are received on ProcessPurchase then no purchases are available to be restored.
6.                 Debug.Log("RestorePurchases continuing: " + result + ". If no further messages, no purchases available to restore.");
7.             });
8.  

This code is return boolean. But I want to know which IAP ID to finish Purchased.
what should I do?

Thank you.
Saksit

 

@mankjon Expect the IAP ID to be returned in the "args" of your IStoreListener.ProcessPurchase(PurchaseEventArgs args) implementation.

 

I have an existing app using the iOS and Google purchasing, and that's all working fine. Now that it's available, I want to add in IAP support for Amazon, but the documentation on this seems to be pretty lacking still.

I currently have some conditional code based on Application.platform, which obviously isn't enough to distinguish between the Google and Amazon app store implementations.

Is there any way to access the information placed in BillingMode.json by the editor switch, or otherwise determine the currently-configured store from application code so the application can follow different paths depending on which store is configured - for things like verifying different product IDs, receipt validation, or extracting alternate receipt data that is specific to the store?

 

Not currently though I can see why it should be easily accessible - I have raised a ticket to add some extended configuration to make it easy to read.

For now you can read and parse the BillingMode.json file using the Resources API -

Code (CSharp):

1. var textAsset = (Resources.Load("BillingMode") as TextAsset);
2. var dic = (Dictionary<string, object>) MiniJson.JsonDecode(json);
3. var store = (AndroidStore) Enum.Parse(typeof(AndroidStore), (string) dic["androidStore"], true);

 

Is it possible to further debug PurchaseFailureReason.Unknown? My purchasing works fine in testing and even during live testing (i.e. not using a test account, actual money changing hands). However some live Android devices are reporting back these unknown errors again and again.

I'm a little at a loss on how to get to the bottom of this. Using Google Play.

 

E.g. is it possible to access PurchaseFailureDescription.message or PurchaseFailedEventArgs.message to get more detailed info?

https://docs.unity3d.com/ScriptRefe...nsion.PurchaseFailureDescription-message.html

https://docs.unity3d.com/ScriptReference/Purchasing.PurchaseFailedEventArgs-message.html

Edit: I'm trying to find the name of the Google Play IStoreExtension, so that I can extend its IStoreCallback.OnPurchaseFailed method, in order to access the error message. Can't figure out how to do that just yet.

 

Hi @nicholasr @Banderous and dudes, can you look at this issue???

http://stackoverflow.com/questions/38015109/google-iab-bizarre-flow-change

what do you reckon?

 

Hi @Fattie,

We're looking into this change now. Check out this forum post for updates as we determine more: http://forum.unity3d.com/threads/bizarre-iap-behaviour-on-android.412981/

 

Hi @pea,

Sorry you're experiencing this problem with your app! Currently, without reproducing the issue either locally or getting a full error log from one of the devices there isn't a way to get the full message. IStoreCallback is an internal implementation so it isn't accessible publicly. The IStoreExtension is public, but can't be used to access the callback. We are working on adding a way to pass more detailed error logging information to users, and hope we'll have it to release soon.

Have the error logs you've gathered indicated whether it was occurring on a specific device or for a certain IAP purchase? We're looking at your Catchy Crystals game and will see if we can reproduce the error on our devices.

 

Hi @erika_d,

Thank you for the great reply. It seems to happen across a range of devices and for all IAP products (consumable or non-consumable). For example, from my logging:



Another issue which may be related is that in Unity Analytics - which automatically tracks Unity IAP purchases - I have a bunch of verified Android purchases. Those purchases aren't actually showing up in my Google Merchant Console. Not sure if that's due to sandbox/test purchases being incorrectly logged in Analytics, or something else related to the PurchaseFailureReason.Unknown.
