Trouble with CustomEvent mediation

[Joachim Stokke]

Hi guys, 

I am having trouble getting mediation to work with Amazon ads. Since it doesn't have an adapter in the AdMob mediation list, I have to write a CustomEvent for it. 

I've followed the instructions, and gone over them multiple times to make sure I didn't miss anything, but I can't get it to work.

Logcat is giving the message: Could not instantiate custom event adapter: com.mypackage.AmazonCustomEventBanner

The code in my custom event class is never called (requestBannerAd)

I don't know how to debug it further. Is there a way for me to know why the custom event can not be instantiated? 

Hope someone can help me out!

I forgot to mention some things:

using play-services-ads 8.1.0

My CustomEventBanner is implementing com.google.android.gms.ads.mediation.customevent.CustomEventBanner

Hi Joachim.

One of the reasons your custom event adapter isn't getting called is because the package and class names defined on AdMob's interface don't match with those in your code.  Could you confirm if this is the case?

Hi!

The package and class names are identical. I've even copy pasted to make sure that is not the issue.

Hi Joachim,

Thanks for confirming with us that that wasn't the case.  Now, the only reason I can think of is, somehow your custom event class might still be in the project, but it is not in the final build (the .apk).  That would explain why the adapter isn't called.  You can use Apktool to decompile your apk, and verify if your class can be found.

Let us know what you find,

Hi again!

You were right! The problem was proguard was removing what it thought was an unused class. After I made it keep the class in the apk, things were working great! :)

Thanks a lot for your help!
