admob rewarded video unity - no fill error

[Kumar Babu]

Hi

I have searched a lot but didnt find a proper tutorial to integrate admob rewarded interstitial ads with unity android app. So I am bit confused and missing some thing. 

I have developed an android app in unity 5.3 and used google mobile ads unity package. Banner ad and interstitial ad is working fine. But rewarded video is not working. It shows "no fill" error. I am using unity ads as third party network mediation in admob and provided required id details in admob. 

Then I went mediation networks of firebase and downloaded unity ad adapter, and placed it inside asset, plugins, android, googlemobileads, libs. But still it shows, "no fill" error. 

In admob, there is showing a pending status beside to the place where ecpm is asked to mention (unityads third party ad in admob)

Where I am going wrong. The adunit of this rewarded video is, 

ca-app-pub-3389677259877868/7964403839

Sorry for my bad english. 

Please guide me in this issue. Thanks.

Hi there,

Thanks for providing your Ad Unit ID. I have tried your Ad Unit ID using our sample apps and I can successfully receive ads.

Now, you said you only included the Adapter. When mediating with Third Party Ad Networks, you need to include both the SDK and the Adapter of the Ad Network you're mediating with.

Can you try importing the UnityAds SDK into your project as well? You can do so by following these instructions:

• Download the UnityAds SDK.
• Place the unity-ads.aar file inside the Assets > Plugins > Android folder.
• Perform the Resolve Client Jars option from the Assets Menu > Play Services Resolver.
• Build and Run your project for Android.

Thanks Joshua for your guidance

I have downloaded the mentioned sdk. And placed the unity-ads.aar file inside the assets>plugins>android folder. Resolve client jars is successful. But when I build I got error as below;

CommandInvokationFailure: Unable to convert classes into dex format.

Hi Joshua,

I fixed the above error. I turned off unity ads, inside unity editor, and after that I build, above "CommandInvokationFailure: Unable to convert classes into dex format." did not occure. But now, still, when I play the game, when i press load reward video, "no fill" error is displaying !!

Addition to my above mail, I have copied unityads.aar file into assets, android folder, then I performed resolve client jars. Resolve client jars is completed. Then I build the game. But when I play the game, I got "no fill" error. 

[Veer Arjun Busani(Mobile Ads SDK Team)]

Hi Kumar,

Just to confirm, you are able to show Banner and Interstitials on your Android device via Unity and it's only the Reward Video Ads that you are currently facing an issue with? If that is the case, then can you try to build this sample app and let us know if you are able to load ads? Your Ad Unit ID seems to be serving UnityAd ads without any issue. 

Thanks,

Arjun Busani

Hi veer, thanks. 

I found your mentioned sample app in another post few hours back, tried and it worked fine with my adunit id. In the mentioned app I noticed, you have placed unity ad folder in assets / plugins / android and you have placed unity adapter inside assets/plugins/android/googlemobileads/lib. I did same but still got "no fill" error.

Currently, I am updating unity to 5.4.1. So I will let you know, status of the issue, tomorrow. 

Thanks alot for the guidances.

Finally it worked. Reward videos are showing. Thanks veer for the sample app. The root problem was the unity ad adapter which I downloaded from here.  I replaced the downloaded unity ad adapter with the one which is present in your sample app. And it worked. The adapter which I downloaded from the mentioned url, was giving no fill error. But now its running smooth. 

Thanks a lot.
