Try using Advertisement.Banner.Hide(); instead of Advertisement.Banner.Hide(destroy);

 

Hello

I changed to simple script

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Advertisements;
3.  
4. public class TestAds : MonoBehaviour, IUnityAdsListener
5. {
6.  
7.     void Awake()
8.     {
9.         Advertisement.AddListener(this);
10.     }
11.  
12.     void Start()
13.     {
14.         bool testMode = GameConfig.Instance.adsTestMode;
15.  
16. #if UNITY_ANDROID
17.         Advertisement.Initialize(Const.UNITY_GAME_ID_ANDROID, testMode);
18. #elif UNITY_IOS
19.             Advertisement.Initialize(Const.UNITY_GAME_ID_IOS, testMode);
20. #endif
21.  
22.         var bannerOptions = new BannerOptions();
23.  
24.         Advertisement.Banner.SetPosition(BannerPosition.BOTTOM_CENTER);
25.         Advertisement.Banner.Show(Const.UNITY_ADS_BANNER, bannerOptions);
26.  
27.         // --------------------------------- IT'S OK----------------------------------------
28.         // Advertisement.Banner.Show(Const.UNITY_ADS_BANNER); // IT'S OK
29.     }
30.  
31.  
32.     public void OnUnityAdsDidError(string message)
33.     {
34.     }
35.  
36.     public void OnUnityAdsDidFinish(string placementId, ShowResult showResult)
37.     {
38.     }
39.  
40.     public void OnUnityAdsDidStart(string placementId)
41.     {
42.     }
43.  
44.     public void OnUnityAdsReady(string placementId)
45.     {
46.     }
47.  
48.     public void ButtonClick()
49.     {
50.         Advertisement.Banner.Hide();
51.     }
52.  
53.  
54.     void Update()
55.     {
56.         if (Input.GetMouseButtonDown(1))
57.         {
58.             Advertisement.Banner.Hide();
59.         }
60.     }
61. }

***
Now causes an error at Start and Update Click or Button click



The problem only appears with "Banner Options"


---------------------ERROR---------------------------------------------
var bannerOptions = new BannerOptions();

Advertisement.Banner.SetPosition(BannerPosition.BOTTOM_CENTER);
Advertisement.Banner.Show(Const.UNITY_ADS_BANNER, bannerOptions)


---------------------IT'S OK---------------------------------------------

Advertisement.Banner.SetPosition(BannerPosition.BOTTOM_CENTER);
Advertisement.Banner.Show(Const.UNITY_ADS_BANNER)

--------------------------------------------------------

Hello

(Case 1342640) Unity Ads - Problem With Banner Hide and Bbanner Options

Answer Customer QA Team:
"After some investigation, I found that this issue appears due to an unassigned BannerCallback hideCallback. After assigning this callback in the BannerAdScript.cs, the issue disappears (see an attached screenshot)."

Problem solved.

 

I was face this problem and I fixed by add "showCallback" and "hideCallback". Thank you!
I think that we need to use these 3 callbacks.
1.showcallback 2.clickcallback 3.hidecallback
