A lot of crashes in latest AdMob when run with mediation (com.moat.analytics).

[Best Mobile Android/iOS Apps & Games]

Hello, everyone! We are using AdMob Unity plugin version 3.18.3 

+ Mediation modules:

GoogleMobileAdsAppLovinMediation-4.1.0

GoogleMobileAdsFacebookMediation-2.4.1
GoogleMobileAdsChartboostMediation-1.3.0

Brings a lot of crashes in Moat analytics, which should be part of MoPub, but we do not have MoPub mediation plugin installed in this app. 

And our AdMob panel mediation settings in Mediation Groups does not have MoPub add source. We have never used MoPub before and not going to.

Please help, because we are afraid to use Mediation now.

Hi there,

Thank you for providing the requested details in private. Those have proven very helpful in my investigation.

I was able to test both your app (from the Play Store) and a built APK I produced from your provided project files, and can confirm that I was getting ads from both of them, with no crashes whatsoever (see attached screenshots and APK file). Could you confirm if the APK I sent works perfectly on your end as well?

That being said, I checked out the device logs during my testing of both your app and the APK, and can also confirm that I did not receive any mentions of "com.moat.analytics.mobile.cha.n" within. Upon further investigation, it seems that the Moat Analytics SDK is not a part of the AdMob SDK. Thus, I would recommend reaching out to the support channels of the Moat Analytics SDK instead for further assistance on this concern.

Let me know if this helps.

Hi there,

I'm afraid that we don't have any insights to share with regard to the interactions of the AdMob SDK with any third-party SDK (such as Moat Analytics). I would recommend reaching out to the support channels of Moat Analytics for further assistance on this.

With that said, I'll be able to consult with the Engineering team on this issue if you can provide a working sample project with the issue reproduced. Feel free to reach out to us again (via Reply privately to author) once you're able to create one.

Hello, It's seems like we have found the reason of crashes.

Moat analytics is the part of chartboost.jar (i just ran through this file and have found multiple references to com.moat.analytics).

We are using chartboost.jar for Chartboost in AdMob Mediation. 

There is another suffered guys:

https://forum.unity.com/threads/java-lang-noclassdeffounderror-failed-resolution-of-landroid-support-v4-content-contextcompat-u.741656/

https://github.com/googleads/googleads-mobile-unity/issues/1011

Please, kindly, ask them to fix the issue and release updated version of chartboost.jar for Unity. Because it cast a shadow to AdMob Mediation, which is perspective technology for Google.

Thank you.

Hi there,

Thank you for your patience on this matter.

I've discussed your concern with the rest of the team. Could you try the suggestions posted on the following threads and see if those will work for you?

• https://github.com/googleads/googleads-mobile-unity/issues/1011
• https://github.com/googleads/googleads-mobile-unity/issues/1009

Otherwise, we recommend posting your concern to the support channels of the Moat Analytics SDK, as we've concluded that this is ultimately more of a third-party SDK issue than an AdMob SDK one.

Let me know if this helps.

Unfortunately, solution does not work. 'Use Jetifier' settings is turned on. App build still crashing on start with the same error.

We've found that crash reproducing when both Chartboost and Facebook mediation used in project. We did additional tests and:

1. Applovin + Chartboost - no crashes.

2. Applovin + Facebook - no crashes.

3. Applovin + Chartboost + Facebook - crashes on start!

So there is some problems between Facebook and Chartboost mediation plugins leading to crashing of chartboost's moat framework (it's embedded to Chartboost https://answers.chartboost.com/en-us/articles/115001489622).
