Introducing Unibill - the cross platform In App purchase plugin!

I've posted a paid job on Job Offerings -- hoping someone out there can help us solve these problems!
http://forum.unity3d.com/threads/paid-fix-errors-with-unibill-on-android.430754/

This is the only significant thing blocking release of our game on Android. Frustrating!

 

I suggest reimporting unibill into your project.

If the inventory editor isn't working then try importing unibill into a blank project, configure your inventory and them copy unibillinventory.json from the new project into your existing project

 

I did do that several days ago, but that didn’t solve the problem….which I believe is fundamentally caused because the “Save” button in Unibill may do other functions besides generate the inventory.json file. The problem is in the Manifest, not in the inventory file. That Unity post details what I’ve tried to solve that…can you help more?

And reimporting Unibill doesn't solve the initial problem either -- when I click "Save" on the inventory editor, I still get this error in the console:

NullReferenceException: Object reference not set to an instance of an object
Unibill.Impl.MiniJsonExtensions.getString (System.Collections.Generic.Dictionary`2 dic, System.String key, System.String defaultValue) (at Assets/Plugins/unibill/src/impl/MiniJSON.cs:757)

So I tried deleting the iOSKey (as indicated on line 61 of UnibillConfiguration), but I still get the error, and while the inventory.json file is rewritten on disk, it still has the iOSSKU so I guess it's not actually getting rewritten? If I can solve this problem, maybe all the other problems will be solve too?

 

Well, we dug into the error and finally figured it out: Unibill was using the wrong MiniJSON - not its own but one from another plugin. And of course they were slightly different... (Good thing Unity has implemented JSON now so that everyone doesn't have to include MiniJSON anymore...) Fixing that fixed all the other problems.

 

Hi @Banderous

We still have an issue with consumable products. We got "this in-app purchase has already been bought it will be restored for free" on iOS.

We found how to reproduce it:

- Open the game
- Tap on a button calling Unibiller.initiatePurchase
- Kill the app
- (apple) Popup of payment is displayed
- Enter your password
- (apple) Popup of confirmation is displayed
- Launch the game again
- Try to buy the same product, have the popup with "this in-app purchase has already been bought it will be restored for free"

We try to call
Unibiller.restoreTransactions();
but it doesn't fix our issue.

We can't give you logs, we need to kill the app to have the issue and XCode stop logging when the app is killed but you have steps to reproduce it.

 

The transaction should complete when you next launch your application. Can you attach a log from when you relaunch the app having killed it?

I also suggest repeating this test with a new itunes connect test user account.

 

Yes it should but it doesn't.

Here's the log after the relaunch:

@Banderous can we force the completion of the transaction?

 

The transaction will still be pending with storekit, it is likely that another plugin is draining the transaction queue before Unibill adds its observer; are you using facebook's SDK, for example?

In UnibillStorekit.mm you should see the following method:

Code (CSharp):

1. -(void) addTransactionObserver {
2.     [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
3. }

Please try replacing with the following:

Code (CSharp):

1. -(void) addTransactionObserver {
2.     SKPaymentQueue* defaultQueue = [SKPaymentQueue defaultQueue];
3.  
4.     BOOL processExistingTransactions = false;
5.     if (defaultQueue != nil && defaultQueue.transactions != nil)
6.     {
7.         if ([[defaultQueue transactions] count] > 0) {
8.             processExistingTransactions = true;
9.         }
10.     }
11.  
12.     [defaultQueue addTransactionObserver:self];
13.     if (processExistingTransactions) {
14.         [self paymentQueue:defaultQueue updatedTransactions:defaultQueue.transactions];
15.     }
16. }
17.  

 

Thanks

It seems working.
I'll test live in the future.

 

I haven't used In App purchase for my games so far, but I might use it in my future games.

 

Hello

I am trying to build a MacOS version of our app and I'm using a few plugins to help with the app(Natcorder, UTMail and Unibill).

I kept getting an error in the application loader when I was trying to validate the app

This didn't go through the application loader.

So, I tried to change the bundle identfiers of these to what we used for our app, and that made it go through the application loader, but it didn't get approved by apple with this mail sent as the issue report

Can anyone help with these issue?
