i added facebook ads as a mediation after implementing it and running the app i got this error from 

MobileAds.initialize(this, "App ad ID")

i used the new mediation test suite all implemented correctly with a internal error for ad loading.
and no ads appear test or live with error code 0 (My app ad isn't new)

In the Log (MainActivity.kt:58) is the line i mentioned above
here is the logcat :

Any updates on this issue? According to the docs TracingController was added in api 28, causing crash on devices < 28?

Hi there

I do not know if this helps for searching the error source, but I am getting the same exception on a Samsung S9, Android 8.0.0,  in my case not with MobileAds 
but from the following code:
mBinding = DataBindingUtil.inflate(LayoutInflater.from(callerContext), R.layout.dialog_general, null, false);


Here the exception stack from the logcat:
