Memory problem Unity Ads on Android

Memory problem Unity Ads on Android
Each time I call Advertisement.Show(null, showOptions); total memory increases by 20Mb and eventually the app freezes or restarts. I've tested this on HTC and Samsung S3. What am I doing wrong?

Here is my code:

Code (CSharp):

1. public void ShowAds(Action onFinished = null, Action onSkipped = null, Action onFailed = null, Action onComplete = null)
2.     {
3.         if (Advertisement.isReady())
4.         {
5.             UserInterface.Instance.setTouchInput(false);
6.             Advertisement.Show(null, new ShowOptions
7.             {
8.                 pause = true,
9.                 resultCallback = delegate(ShowResult result)
10.                 {
11.                     Debug.Log("Unity Ads : " + result.ToString());
12.  
13.                     switch (result)
14.                     {
15.                         case ShowResult.Finished:
16.                             if (onFinished != null)
17.                                 onFinished();
18.                             break;
19.                         case ShowResult.Skipped:
20.                             if (onSkipped != null)
21.                                 onSkipped();
22.                             break;
23.                         case ShowResult.Failed:
24.                             if (onFailed != null)
25.                                 onFailed();
26.                             break;
27.                         default:
28.                             throw new ArgumentOutOfRangeException("result");
29.                     }
30.  
31.                     UserInterface.Instance.setTouchInput(true);
32.  
33.                     if (onComplete != null)
34.                         onComplete();
35.                 }
36.             });
37.         }
38.     }

 

Hello, Victor_Kallai,

I couldnt see a mistake on your code, before your production code , did you try using unity-ads with some plain(simple)(basic) code for test purposes. Something default code just for test. Because with this code I cant see through whats going on with your (Action Type) .
Also you can get better help from this forum with a logcat attachment.

Thank you,

 

There is nothing interesting in my Android log, I've already checked it; when the memory increases over a value, my game process is killed by Android os.
I've checked with Unity profiler, each time I show an unity ad, the total memory increases with 20Mb but only on Android, this does not happen in Editor.
Inside my game I call the above function like this:

Code (CSharp):

1.         UnityAdsManager.Instance.ShowAds(
2.             delegate
3.             {
4.                 continueLevelFromFail();
5.             }
6.         );
7.  

I seems like the video ad object is left behind in memory, do I have to delete it myself? Shouldn't it be deleted automatically when I close the ad?
