Adding an admob causes an error that does not exist. error - java.lang.IllegalArgumentException: Service not registered: lt@777a78f

To use the Admob.

Implementation 'com.Google.android.gms:play-services-adds:19.2.0'

I added this part. I added Menifest.

(I've filed an official Admob document. )

Sample advertisement is also good. But the error message below kept coming up.
There is no big problem or the app turns off..

I was wondering if it was a conflict with the old code. so
Create an empty project with a new project.

Added admob to empty project.
The same error occurs.

Implementation 'com.Google.android.gms:play-services-adds:19.2.0

If you just write the part where you add the Admob... The same error is generated.

In this case, has anyone tried debugging?

This was driving me slightly insane until I noticed that I include Firebase in my build.gradle as follows:

implementation platform('com.google.firebase:firebase-bom:25.12.0')
implementation 'com.google.firebase:firebase-analytics'
implementation 'com.google.firebase:firebase-crashlytics'
...

Android Studio build.gradle was not prompting me to update to the latest version:

implementation platform('com.google.firebase:firebase-bom:26.1.0')

After making this update, and checking back to confirm with the previous version, the warning has disappeared.

I think firebase may integrate some of the core Google libraries, so possibly the same fix will be obtained simply by updating your com.google.android.gms:play-services-xxx libraries

Hope this helps someone out there.
