Unsupported class file major version 61

Looks like androidx.annotation.annotation-experimental-1.4.0.aar was compiled with Java version newer than you use. To solve - either use older version of androidx.annotation.annotation or newer Java (I’d go with first option)

[sevag6]

Please can you explain how to use old version of androidx.annotation.annotation ?

You should find out where exactly that dependency is coming from. One of the options would be looking through dependencies.xml of your project’s plugins, another - exporting Unity project and checking dependency tree in Android studio.
One you know that - you can try either replacing that dependency with older version or downgrading plugin version

In the same situation here with Levelplay with Admob network. I’m using:

• UnityEditor 2022.3.51f1
• 

I understand downgrade the androidx.annotation.annotation-experimental-1.4.0.aar how can I get that? Here is my ISAdMobAdapterDependencies.xml:

<dependencies>
  <unityversion>4.3.67.0</unityversion>
  <androidPackages>
	<androidPackage spec="com.google.android.gms:play-services-ads:23.5.0">
  	<repositories>
    	<repository>https://maven.google.com/</repository>
  	</repositories>
	</androidPackage>
  </androidPackages>
  <androidPackages>
	<androidPackage spec="com.ironsource.adapters:admobadapter:4.3.47">
  	<repositories>
    	<repository>https://android-sdk.is.com/</repository>
  	</repositories>
	</androidPackage>
  </androidPackages>
  <iosPods>
	<iosPod name="IronSourceAdMobAdapter" version="4.3.58.0">
  	<sources>
    	<source>https://github.com/CocoaPods/Specs</source>
  	</sources>
	</iosPod>
  </iosPods>
</dependencies>

Any other alternative solution?

I downgraded the AdMob adapter to successfully build our project.

Were you able to solve the issue? Since I’m using source control, I discarded 3 or 4 files related to the AdMob adapter update. For me, it wasn’t worth spending more time trying to find a solution, as I didn’t encounter any issues with the previous version of the AdMob adapter.

We haven’t solve the problem yet. Sadly, we are still waiting for a response from ironSource. Which versions of Admob adapter, Ads Mediation package and Level mediation are you using?
