Unity ad Extension java error


I am getting this error while using the Unity extension by Oseamiya.

Error screenshot attached, and blocks can be seen in the background.

I get this error in Companion, and also after deploying to Playstore’s Open testing.

I have selected Test mode for the Extension, and game id is filled.

I get the error even when blocks are disabled, and only the extension is placed.

Kindly help.


This won’t work in this companion, you’ll need to export it.

I have checked it in Open testing mode after downloading from Playstore.

You are right. I got the test ads to show by using Interstitial ads this time.

Testing is best done with Interstitial_Android placement id, as the Interstitial ads are quick to show compared to banners.
