Android Error: "Unity Ads cannot show ads: webapp not initialized"

Hi everybody!

Unity Ads shows a black screen on Android (not Unity for Android, an Android game), the error shown is this:

I/UnityAds(17755): com.unity3d.ads.android.UnityAds.canShow() (line:242) :: Unity Ads cannot show ads: webapp not initialized

I think it has something to do with the "xml layout", I have my own "res/layout" files so I copied the Unity Layout there, but it seems not to read them.

What I have to do?

Thanks.

 

Just to make sure, you have called UnityAds.init(), right?

 

Yes! I'm attaching the code right here

 

Ok, so I didn't remember to uncomment the code so the init call wasn't done. I did it because a bigger problem: I show the Unity Ads and the screen shown is complete BLACK and you cannot close it. This is the output:

Hello,

This issue has been addressed in the latest SDK update. Please follow these instructions to update:

1. Download the [unity-ads.aar](https://github.com/Applifier/unity-ads-sdk/raw/master/unity-ads.aar) file
2. Remove all previously added Unity Ads integration related files/references from your project
3. On Android Studio, Click File -> New -> New Module
4. Select Import .JAR/.AAR Package, click Next
5. Locate unity-ads.aar, module name should change to unity-ads, click Finish.
6. Now, Right Click the default module of your project, select Open Module Settings
7. Ensure that your default module is selected, click the Dependencies tab
8. Click the plus sign in the bottom of the screen, choose Module Dependency
9. Choose unity-ads from the popup that opens

This should fix the R$Layout issue.

 

having the same error using latest unity-ads.aar

I/UnityAds(17755): com.unity3d.ads.android.UnityAds.canShow() (line:242) :: Unity Ads cannot show ads: webapp not initialized

here is my complete log

 

mmh ok, following the code, it seems that the webapp state is not set as initialized until I set a Listener...

in UnityAdsMainView.java:138

if (!UnityAdsProperties.isAdsReadySent() && UnityAds.getListener() != null) {
UnityAdsDeviceLog.debug("Unity Ads ready.");
UnityAdsProperties.setAdsReadySent(true);
UnityAds.getListener().onFetchCompleted();
}

 

THANK YOU!
