Resolved Unity Iap in-app-puchase 4.9.4 NoSuchMethodError 'initialize'

I updated Unity Iap in-app-puchase 4.4.1 to 4.9.4. because billing version 4 -> 5.
Unity Editor Version is 2021.3.10f1
but I have Problem.
This is android log cat.

java.lang.NoSuchMethodError: no non-static method with name='initialize' signature='(Landroid.app.Application;Lcom.android.billingclient.api.PurchasesUpdatedListener;Z)V' in class Ljava.lang.Object;

and I found that here is problem

Code (CSharp):

1.             UnityPurchasing.Initialize(this, builder);

If I use billing version 4, there is no bug, but if I use version 5, there is a bug.

 

Make sure your main class is inheriting from IDetailedStoreListener

using UnityEngine.Purchasing;
using UnityEngine.Purchasing.Extension;

You'll also need to fix
void OnPurchaseFailed(Product product, PurchaseFailureDescription failureDescription);

 

Thanks for the reply.
but bug again...

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Purchasing;
5. using UnityEngine.Purchasing.Security;
6. using System;
7. using Gaa;
8. using UnityEngine.Purchasing.Extension;

Code (CSharp):

1. public class IAPManager : Singleton<IAPManager>, IDetailedStoreListener
2.  

and I fixed

Code (CSharp):

1. public void OnPurchaseFailed(Product i, PurchaseFailureReason p)
2.     {
3.         if (p == PurchaseFailureReason.PurchasingUnavailable)
4.         {
5.             // IAP may be disabled in device settings.
6.         }
7.     }
8.     public void OnPurchaseFailed(Product i, PurchaseFailureDescription p)
9.     {
10.         RestoreButtonClick();
11.  
12.  
13.         Debug.Log(p.ToString());
14.         if (p.reason == PurchaseFailureReason.DuplicateTransaction)
15.         {
16.             try
17.             {
18.                 ResetrTransaction();
19.             }
20.             catch....................................

java.lang.NoSuchMethodError: no non-static method with name='initialize' signature='(Landroid.app.Application;Lcom.android.billingclient.api.PurchasesUpdatedListener;Z)V' in class Lcom.android.billingclient.api.BillingClientImpl;

java.lang.NoSuchMethodError: no non-static method with name='initialize' signature='(Landroid.app.Application;Lcom.android.billingclient.api.PurchasesUpdatedListener;Z)V' in class Ljava.lang.Object;

 

Whats your builder look like?

Code (CSharp):

1.  
2. var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
3. UnityPurchasing.Initialize(this, builder);
4.  

 

my builder is

           

           var module = StandardPurchasingModule.Instance();

            ConfigurationBuilder builder = null;

#if UNITY_ANDROID && !UNITY_EDITOR



         //## android is here ##



            if (Application.platform == RuntimePlatform.Android && module.appStore == AppStore.GooglePlay)

            {

                builder = ConfigurationBuilder.Instance(Google.Play.Billing.GooglePlayStoreModule.Instance());

                m_IsGooglePlayStoreSelected = true;

            }

#else

            builder = ConfigurationBuilder.Instance(module);



            /*m_IsCloudMoolahStoreSelected = Application.platform == RuntimePlatform.Android && module.appStore == AppStore.CloudMoolah;

            m_IsSamsungAppsStoreSelected = Application.platform == RuntimePlatform.Android && module.appStore == AppStore.SamsungApps;*/

            m_IsGooglePlayStoreSelected = false;

#endif

            for (int i = 0; i < Item_Production_ID.Count; i++)

            {

                builder.AddProduct(Item_Production_ID[i], UnityEngine.Purchasing.ProductType.Consumable, new UnityEngine.Purchasing.IDs

            {

                { Item_Production_ID[i], AppleAppStore.Name },

                { Item_Production_ID[i], GooglePlay.Name},

            });

            }

            Debug.Log(builder.products);

            Debug.Log("## Initialize ~~ ##");

            Debug.Log("this : " + this + "/// builder : " + builder);

            UnityPurchasing.Initialize(this, builder);

            Debug.Log("## Initialize success~~ ##");

 

Try removing this part as this is whats overriding your builder see: https://docs.unity3d.com/Packages/com.unity.purchasing@4.9/manual/UnityIAPInitialization.html

Code (CSharp):

1.  
2. if (Application.platform == RuntimePlatform.Android && module.appStore == AppStore.GooglePlay)
3.             {
4.  
5.                 builder = ConfigurationBuilder.Instance(Google.Play.Billing.GooglePlayStoreModule.Instance());
6.  
7.                 m_IsGooglePlayStoreSelected = true;
8.  
9.             }
10.  

If a unity dev is reading, would appreciate you guys being a bit more active to bug posts here.

 

I really appreciate your answer. The bug has been resolved. There are still a few more parts to fix, but payment is now possible.

                //builder = ConfigurationBuilder.Instance(Google.Play.Billing.GooglePlayStoreModule.Instance());

                builder = ConfigurationBuilder.Instance(module);

I fixed here and resolve the problem.
this("Google.Play.Billing.GooglePlayStoreModule.Instance") is problem.
thank you so much.
