Resolved no udp sdk initialization detected

Hi
ive been trying to use UDP and ive taken care of everything but this last part seems to be unfixable.
i run my apk on a phone but steal says no udp sdk initialization detected.
My game doesnt have any IAP. its free.
i found that i should implement UDP initialization code. but i dont know how to and where to put that.

 

I just woke up, so I might miss something, but shouldn't this script take care of the UDP SDK initialization? Just attach it to any GameObject in your scene...

1. using UnityEngine;
2. using UnityEngine.UDP;
3. 
   
4. public class UDPManager: MonoBehaviour, IInitListener
5. {
6. void Awake()
7. {
8. StoreService.Initialize(this);
9. }
10. public void OnInitialized(UserInfo userInfo)
11. {
12. Debug.Log("Initialization succeeded");
13. // You can call the QueryInventory method here
14. // to check whether there are purchases that haven’t be consumed.
15. }
16. 
    
17. public void OnInitializeFailed(string message)
18. {
19. Debug.Log("Initialization failed: " + message);
20. }
    
21. }
