[Solved] Culture problematic when using 'fr-FR' under Android

Hey guys,
we currently encounter an Exception ("FormatException: Invalid character at position 2") during UnityPurchasing.Initialize. This happens when the Thread.CurrentThread.CurrentCulture is set to CultureInfo.CreateSpecificCulture("fr-FR") under Android. We already had the same issue using Unibill, but we were able to write an own fix since we had the Code.

StackTrace:

Our "fix" for Unibill was something similar to this: (Util.cs / DeserialiseProductList)

decimal priceDecimal;
if (!decimal.TryParse(details.getString("priceDecimal"), out priceDecimal)) {

priceDecimal = decimal.Parse(details.getString("priceDecimal"), NumberStyles.Any, CultureInfo.CreateSpecificCulture("en-GB"));​

}​

Maybe it's also applicable for the current UnityIAP implementation since it based on Unbill.

I'm currently experiencing the same error: https://forum.unity3d.com/threads/exception-in-unity-iap-on-google-play.437437/

If there is a workaround I'd love to know, as I need to release this asap

 

@ap-unity Thanks

@WillemKokke Indeed there is a workaround. Just initialize the app and payment with 'en-US' (or a other working one) and switch to the right after the payment is fully initialized.

Thread.CurrentThread.Culture = CultureInfo.CreateSpecificCulture("en-US");
...
UnityPurchasing.Initialize(<your IStoreListener>, <your ConfigurationBuilder>);
...

In your IStoreListener:
public void OnInitialized(IStoreController controller, IExtensionProvider extensions) {

...
Thread.CurrentThread.Culture = CultureInfo.CreateSpecificCulture("<the user culture>");​

}

 

Life saver, thanks!

 

Hi @MoinTom

I can't get your workaround to work I'm afraid.

I think the deserialisation and parsing of the product descriptions probably happens on a thread other than the unity main thread making the modifications I make pointless.

Am I doing something wrong?

I'm using the following code

Code (CSharp):

1.     public void Start()
2.     {
3.         var module = StandardPurchasingModule.Instance();
4.         var builder = ConfigurationBuilder.Instance(module);
5.  
6.         // setup builder here //
7.  
8.         Debug.Log("[CultureInfo] CultureInfo.CurrentCulture.Name: " + CultureInfo.CurrentCulture.Name);
9.         Debug.Log("[CultureInfo] CultureInfo.CurrentCulture.DisplayName: " + CultureInfo.CurrentCulture.DisplayName);
10.         Debug.Log("[CultureInfo] Thread.CurrentThread.CurrentCulture.Name: " + Thread.CurrentThread.CurrentCulture.Name);
11.         Debug.Log("[CultureInfo] Thread.CurrentThread.CurrentCulture.DisplayName: " + Thread.CurrentThread.CurrentCulture.DisplayName);
12.  
13.         savedCulture = CultureInfo.CurrentCulture;
14.         Debug.Log("[CultureInfo] Saved Culture: " + savedCulture.DisplayName);
15.         Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("en-GB");
16.         Debug.Log("[CultureInfo] Switched to Culture: " + Thread.CurrentThread.CurrentCulture.DisplayName);
17.  
18.         // Now we're ready to initialize Unity IAP.
19.         UnityPurchasing.Initialize(this, builder);
20.     }
21.  
22.  
23.     public void OnInitialized(IStoreController controller, IExtensionProvider extensions)
24.     {
25.         Thread.CurrentThread.CurrentCulture = savedCulture;
26.         Debug.Log("[CultureInfo] Restored culture to Culture: " + Thread.CurrentThread.CurrentCulture.Name);
27.     }

This is the cleaned up log (OnInitialized is never called)

 

Never mind, I've fixed it by replacing the offending function inside Stores.dll myself.
