Could not show rewarded video ad from adapter.

[Steven Haggerty]

Hi there,

We've recently switched to using Admob for mediated ads.

Occasionally, I get an error where an ad fails to show (see below log).

The ad unit is:ca-app-pub-4628249632882103/2677340878

I cannot provide you with a project you can this can be replicated. I'm in crunch at the moment

so don't have time to replicate this in your sample app.

It's exactly the same issue as this issue posted a month ago:

https://groups.google.com/forum/#!topic/google-admob-ads-sdk/yKkPOm4xVJ8

So it's not unique to my project.

All I do is sit and play our app over and over, requesting rewarded movies. It took approximate 2 hours.

I look forward to you reply,

Many thanks,

Steven Haggerty,

Director,

Rubicon Development.

Just tried with 11.0.0, same thing.

I can't detect and work around the problem as the showad function returns void. It looks like you need a failedToShowRewarded() override.

Steve.

Hi, I have the exact same issue with AdColony and mediation with rewarded video.

Another thread with the same issue on Unity: https://groups.google.com/forum/embed/#!category-topic/google-admob-ads-sdk/android/VByH8vDmDx0

Thanks for your support.

[Bongkyu Cha]

내가 확인 결과,

"MobileAds.getRewardedVideoAdInstance(context)"로 생성을 하고,

"RewardedVideoAd.destroy(context)"를 호출을 하고 다시 "MobileAds.getRewardedVideoAdInstance(context)"로 생성을 하면,

"RewardedVideoAd.show()"호출 시에 자주 발생을 한다.

이런 경우 해당 SDK Library에서 throws Exception을 발생 시켜줘야 Application에서 이후 동작을 처리할 수 있을 거 같다.

Could not show rewarded video ad from adapter.(java.lang.NullPointerException)

위의 Error 가 발생하면, "onRewardedVideoAdFailedToLoad()" API가 호출되지 않아서 문제가 있다.

Hi there,

As previously mentioned, this is already a known issue and the team is still investigating the possible cause of the issue. While there are no updates as of yet, would you be able to provide to us the affected Ad Unit IDs, as well as the names of the Ad Networks it is mediating to? It will help us in further investigating the cause of the issue.

Additionally, would you be able to try to check if the Rewarded Ad is loaded first before trying to show the ad and verify if this helps lessen the occurrence of the error?

Hi,

Thanks for your reply Mr. Joshua  Lagonera.

Ad unit id - ca-app-pub-8169699032060747/4014460698

Ad network  - InMobi

 'com.google.firebase:firebase-ads:11.2.0'
 'com.inmobi.monetization:inmobi-ads:6.2.2'

if (mAd.isLoaded()) {
    mAd.show();
}

 check if the Rewarded Ad is loaded first not helped me I already using that.

Thanks,

Ajesh

Hello, i am having issues displaying Reward Video Ads, for the real ads as well as test ads, i am also cannot be able to use test ads, i have download sample code for Rewarded Video Ads, the strange thing your sample reward video ad code is also not working and says Failed to load ads, kindly help me resolve the issue as soon as possible, because i am really worried, i have implemented correct way and fulfill all the steps required to display Rewarded ads, but still its not loading even the test ads. I am waiting for your kind and urgent response soon :(

Hi,

I have exact same problem with rewarded videos and test ads. Do you have any update on this?

Thanks. 

[Joshua Lagonera (Mobile Ads SDK Team)]

Hi there,

I'm afraid we do not have any updates to share regarding the issue. However, as previously mentioned, we will get back to this thread once we have any updates.

With that said, if you can provide a sample project where the crash can be replicated locally, then kindly provide it to us to help further investigate the issue.

Hello,

I'm not sure if this was mentioned before but I think the issue is proguard related, maybe there is a rule that can be added to proguard file.  I was getting that same stack trace when I tried to load an add and then I changed minifyEnabled to false and it started working for me.

[Joshua Lagonera (Mobile Ads SDK Team)]

Hi Brian,

Interesting. I'll be sure to pass this information to the rest of the team while the investigation is ongoing. However, can you provide us with a sample project where you can replicate the issue since you mentioned you were getting the same stack trace before? It would be extremely helpful in finding out the root cause.

[Dusan Vita]

Hi everyone,

I was experiencing the same issue by following the instructions from this link https://developers.google.com/admob/android/rewarded-video;

I was able to overcome the issue by instead following the implementation from the official example: https://github.com/googleads/googleads-mobile-android-examples/blob/master/java/admob/RewardedVideoExample/app/src/main/java/com/google/ads/rewardedvideoexample/MainActivity.java;

There are 2 main differences, not sure which one is the culprit for the issue, but changing both solved my problem:

- Invoking activity lifecycle methods on the RewardedVideoAd instance after calling the super methods of the activity.

- And not invoking RewardedVideoAd.destroy(Context) at all.

My use case is having a separate activity for showing products and ad request button, so the issue was occurring when this activity was destroyed and then created again, was not able to reproduce in the first creation of the activity, but could be reproduced each time the activity is destroyed and started again.

Hope this helps both to you implementing the library and to those debugging it.

Best regards,

Dusan

[Joshua Lagonera (Mobile Ads SDK Team)]

Hi Dusan,

Thank you for adding your investigation on this issue. I will make sure to pass these information to our team to help with the investigation. However, would you be able to provide us a sample project/application where we can replicate this issue?

Regards,

Joshua Lagonera

Mobile Ads SDK Team

[Brian Rojas]

Hey Josh, I was able to get it working eventually, I think the issue was my fault, I don't think I had the proguard rules setup properly.

[Jeffrey Chen]

I am having the same issue, and I created an example application where I can replicate it consistently: https://github.com/jchen1352/AdMobBug

The problem is in RewardedVideoAd.destroy, since removing that fixes the problem.

[Joshua Lagonera (Mobile Ads SDK Team)]

Hi Jeffrey,

Thank you for providing an example application. I can confirm that I am also able to replicate the issue consistently using it, as well as the sample steps you provided.

I'm going to forward this information to the rest of the team and get back to this thread for updates regarding this issue.

Hi Jeffrey,

The team confirmed that there's a fix already in place for this but I can't provide you any definite timelines on the release. I suggest that you keep an eye on our Release Notes for future updates.

Thank you again for reporting this to us and for taking the extra effort to create a sample application which really helped with our investigation.

Hi,

Though the error message "Could not show rewarded video ad from adapter" you got is similar to the original report, the Exception is different since the original report is throwing NullPointerException.

For the original report in this thread, a fix is already in place for this, however, we can't provide you any definite timelines on the release so it's best that you keep an eye on our Release Notes for future updates.

However, for the "IllegalStateException: no adapter ready to start" error you are getting, could you confirm if you were able to follow all the necessary steps as mentioned in this guide for mediation with FAN?

Could you provide to us the following privately (using Reply privately to author option) so we can further check on our end?

• Link to your app or a miniature sample project where issue is reproducible
• Complete stack trace

Regards,

Hi Zhang,

Were you able to check if you were able to follow all the necessary steps mentioned in this guide for mediation with FAN?

If you are still getting the "IllegalStateException: no adapter ready to start" error, then could you provide to us the following privately (using Reply privately to author option) so we can further check on our end?
