If you are using Firebase for notifications then to initialize fire base you have to do something like this FirebaseMessaging.getInstance().subscribeToTopic(Config.TOPIC_GLOBAL); But do not forget to use services and files related to Firebase services — Snehal Gongle

Are you seeing this with release and debug builds? If release only, are you using ProGuard? — John O'Reilly

There is a bug in Google Play Service. Here is the link to Google Group: https://groups.google.com/forum/#!search/appMeasurement/google-admob-ads-sdk/9Cukd02En9o/ELCZfzjUCQAJ It should be fixed if one of the next release

Had the same issue today, and adding this to the Proguard/R8 rules fixed it:

-keep class com.google.android.gms.measurement.AppMeasurement {public *; }
