Game crashes after splash screen (caused by ads)

[benw...@gmail.com]

Hi,

I'm building a game in Unity and it used to work fine with the Admob SDK.  I've since moved to a newer Mac and now it crashes on my Android device after the splash screen.  I'm pretty new to Android development but here's the LogCat that I think explains the issue:

I'd really appreciate some guidance here as to how I might fix this?

Many thanks!

Ben

Hi Ben,

Thank you for providing to us the crash logs and other helpful details.

The ClassNotFoundException seems to suggest that the Mobile Ads SDK was not imported properly on your end. Could you check if you were able to follow these instructions for importing the Google Mobile Ads Unity plugin?

Also, for testing purposes, could you test if you can replicate the same error if you build and run our sample app? 

Regards,

Ivan Bautista
