Interstitial AdActivity crash

[易昊]

Hi,

I have used Admob interstitial ads in my app, and sometimes the interstitial ads activity crash, the error log is as below. 
I found this error is caused by I didn't hold the PublisherInterstitialAd reference, and I  new it every time, then GC will call com.google.android.gms.ads.nonagon.ad.interstitial.b.finalize(), and it at last throw the exception.

It can be worked around by making PublisherInterstitialAd reference retained, but I hope you can fix this issue. Thanks!

I believe we are having the same issue. During the middle of ad playback the following error happens on Android 6.0+

Hi Joe,

Thank you for reaching out to us. I'm Ziv, Teejay's colleague, and I will be assisting you on your concern since he is out-of-office today.

The error log you have provided is indeed related to the issue outlined in this thread. The bug with WebView has already been fixed as per our Engineering team, however I cannot give a definite timeline for when the update will be released. You may follow our blog or release notes for future updates.

In the meantime, you may use the following workaround: kindly retain a reference to the rewarded ad in question while it is still playing onscreen, and use a new variable instead when you want a load a new rewarded ad during this time.

Regards,
Ziv Yves Sanchez

[Joe Hopkins]

Hi Ziv,

Can you clarify what you mean by retaining a reference to the rewarded ad in question? We updated our ad class to do the following, the but issue remains.

private RewardBasedVideoAd currentRewardedAd;//for storing reference to the ad 

                                     

...               

                 

if (RewardBasedVideoAd.Instance.IsLoaded())

        {
            this.currentRewardedAd = RewardBasedVideoAd.Instance;
            this.currentRewardedAd.Show();


            //Original before workaround:
            //RewardBasedVideoAd.Instance.Show();
        }  

[Joe Hopkins]

How do you retain the reference? We are having the same with  RewardBasedVideoAd.Instance

[Mobile Ads SDK Forum Advisor Prod]

Hi Joe,

You may try using the new Rewarded Ads API instead, and apply the workaround there if necessary (that is, you may simply repeat this step using a new variable instead of recycling the old one when requesting a new ad).

Let me know if this works for you.

[陈云龙]

I encounter the same issue, and I fixed it

maybe you should stop load new interstitial Ad when the current ad is showing
