It shows multiple BuildConfig files leading to a failure.

Check if you have built in ads enabled and also ads aar in your project.

Having only either of one should fix it.

 

Now its working. Thanks

 

It doesn't work for me... can you help me?

 

In case someone else hits this problem - In the unity package manager I had Advertisements version 3, I needed to 'update' it to unity ads v2.08 to get it to work with AdMob and get rid of this dex error.

 

What do you mean by 'aar'

 

.aar is the extension used for android libraries. It will have all resources and dex files packed in the single file.

 

I had the same problem. If you copy the aar file to the libs folder and make the module as in the unity instructions, it may cause an error because there are two aar files. Corrects after deleting aar file in Libs folder
