Purchases not restored on Android - Error: You already own this item

Hi,

I searched before posting and apparently Android is supposed to automatically restore purchases using the IAP listener but its not working in my case.

So as the title says, I purchased a non-consumable and then uninstalled. The purchase is not restored when I re-install. When I click the buy button I get the error: "You already won this item"

I am using IAP 3.0.1 and Unity 2019.4.23f1

• I am populating the catalogue in Editor and set it to automatically initialize.

• I then created a Unity IAP button and am calling the following function in OnPurchaseComplete()

Code (CSharp):

1. public void OnPurchaseComplete(Product product)
2.     {
3.         if (product != null)
4.         {
5.             switch (product.definition.id)
6.             {
7.                 case "weapons_unlock":
8.                     // YAY!! someone actually spent actual money on this lousy game!
9.                     if (weaponUnlock != null)
10.                     {
11.                         weaponUnlock.UnlockAllWeapons();
12.                     }
13.                    
14.                     //reload the scene to properly repopulate shop
15.                     SceneManager.LoadScene(SceneManager.GetActiveScene().name);
16.                     break;
17.  
18.                 case "disable_ads":
19.                     PlayerPrefs.SetInt("ShowAds", 0);
20.                     break;
21.  
22.                 default:
23.                     print("Sorry, this is not a valid product.");
24.                     break;
25.             }
26.         }
27.     }

I also adde an IAP Listener in my scene and provided the same function above to the OnPurchaseComplete()

But the weapons are not being unlocked.

What am I doing wrong?

Thanks

 

@farazk86 Can you show the Inspector properties for your IAP Button? Ensure to select the Consume checkbox (it is a poorly named checkbox). Also, I would encourage you to Debug.Log (print) your product.definition.id to ensure you are getting the right product. The "Already owned message" is correct for a non-consumable.

 

Hi Jeff, Thanks for the reply.

The Consume checkbox is already checked. Here is the screenshot:

 

Can you show your code for IAPManager? Attach it here, It looks like you might be mixing Codeless and Scripted IAP.

 

Here is the full code for IAPManager

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5. using UnityEngine.Purchasing;
6.  
7.  
8. public class IAPManager : MonoBehaviour
9. {
10.     private WeaponUnlockSystem weaponUnlock;
11.  
12.     private void Start()
13.     {
14.         weaponUnlock = FindObjectOfType<WeaponUnlockSystem>();
15.     }
16.  
17.     public void OnPurchaseComplete(Product product)
18.     {
19.         if (product != null)
20.         {
21.             switch (product.definition.id)
22.             {
23.                 case "weapons_unlock":
24.                     // YAY!! someone actually spent actual money on this lousy game!
25.                     if (weaponUnlock != null)
26.                     {
27.                         weaponUnlock.UnlockAllWeapons();
28.                     }
29.                    
30.                     //reload the scene to properly repopulate shop
31.                     SceneManager.LoadScene(SceneManager.GetActiveScene().name);
32.                     break;
33.                    
34.                 case "disable_ads":
35.                     PlayServices.instance.UnlockAchievement(GPGSIds.achievement_gracious_runner);
36.                     PlayerPrefs.SetInt("ShowAds", 0);
37.                     break;
38.  
39.                 default:
40.                     print("Sorry, this is not a valid product.");
41.                     break;
42.             }
43.         }
44.     }
45.  
46. }
47.  

 

Please add the mentioned Debug.Log statements which will show in the device logs. Is the IAP listener active when you launch your game? I might suggest to use scripted vs Codeless IAP, we need to update Codeless IAP. I would suggest to start with the updated Sample IAP Project here https://forum.unity.com/threads/sample-iap-project.529555/#post-6950270 and https://forum.unity.com/threads/how-to-capturing-device-logs-on-android.528680/

 

Here is the logcat for what I press the unlock weapons button:

However, my Debug.Log is not showing up in there.. I added the following to my code above:

Code (CSharp):

1. public void OnPurchaseComplete(Product product)
2.     {
3.         if (product != null)
4.         {
5.             Debug.Log("This is the product.definition.id: " + product.definition.id.ToString());
6.             switch (product.definition.id)
7.             {
8.                 case "weapons_unlock":
9. .
10. .
11. .
12. .

 

And yes IAPListener is active in scene.. here is the screenshot for it::

 

@farazk86 So that code is not firing which means the Listener is not active or placed into your opening scene. I would highly recommend to use Scripted IAP, and Initialize IAP in Start() or Awake(). Your screenshot only shows the Listener properties, not its placement in any scene.

 

Thats unfortunate

So by scripted API you mean the sample here: https://forum.unity.com/threads/sample-iap-project.529555/#post-6950270

If I use that, Am I to remove my current IAP button and IAP Listeners?

Thanks

 

So its finally working

You mentioning the listener not being in the opening scene made me try something. I have a Splash Screen where I initialize a few things and then I have the start menu. Where I had the listener and the IAPButton.

I copied the IAPListener and IAPManager to the very first scene - the splash screen and now my purchases are restored automotically.

I did not know the IAP stuff has to be in the very first scene in the game.
