I get an error when importing AdmobMediation-UnityAds.

[Allen Oh]

Admob has been applied to the app I'm developing.

I applied FacebookAudianceNetworkMediationAdaptor to this app and it compiles successfully.

I then imported the UnityAdsMediationAdaptor in the same way to this app.

However, there is a compilation error after that :

CommandInvokationFailure: Gradle build failed. 

C:/Program Files/Java/jdk1.8.0_221\bin\java.exe -classpath "C:\Program Files\Unity\Hub\Editor\2019.1.10f1\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-5.1.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "assembleRelease"

It happens the same on my Windows PC and MacBook.

Unity3D : 2019.1.10f1

Google Mobile Ads Unity Plugin : v3.18.1

Google Mobile Ads Facebook Mediation : v2.4.0

Google Mobile Ads UnityAds Mediation : v2.1.0

I want to know what is causing this problem.

Hello Allen,

Thanks for reaching out to us. Can you please provide us a sample project with your implementation for us to take a look? You can use "Reply Privately to Author" option to share the details privately. Before that, can you just make sure that all the implementation guidelines are followed from our documentation properly?

Hi Deepika,

Thank you for your quick reply.

I think I've solved this problem.

There were a lot of compilation errors for "duplicate class com.unity3d.ads", so I thought about why.

So I deleted the file "Plugins / Android / com.unity3d.ads.unity-ads-3.1.0.aar" to solve the duplication problem and it compiles successfully.

Modified "UnityMediationDependencies.xml" because running "Android Resolve" will download this file again.

<dependencies>

  <androidPackages>

    <androidPackage spec="com.google.ads.mediation:unity:3.1.0.0">

      <repositories>

        <repository>https://jcenter.bintray.com/</repository>

      </repositories>

    </androidPackage>

    <!--

    <androidPackage spec="com.unity3d.ads:unity-ads:3.1.0">

      <repositories>

        <repository>https://jcenter.bintray.com/</repository>

      </repositories>

    </androidPackage>

    -->

  </androidPackages>

  <iosPods>

    <iosPod name="GoogleMobileAdsMediationUnity" version="3.1.0.0">

      <sources>

        <source>https://github.com/CocoaPods/Specs</source>

      </sources>

    </iosPod>

  </iosPods>

</dependencies>

Currently it runs fine without errors.

But I'm not sure if this is the right way because I don't know whether Unity ads are playing normally.

In the sample project (Hello World), even if there is "com.unity3d.ads.unity-ads-3.1.0.aar" when importing UnityAds mediation, it compiles successfully.

However, deleting "com.unity3d.ads.unity-ads-3.1.0.aar" still does not cause an error.

Is it OK to delete this?

Regards,

Allen

Hello Allen,

I would not recommend that you alter any dependencies from the existing Adapter or SDK. And let us know if you are having any issues without altering the adapter.
