    Make sure your dependencies are all up to date with each other. A lot of what you're using is rather old. https://firebase.google.com/support/release-notes/android – Doug Stevenson Jan 23 '20 at 16:42
  • when i add latest version of all the firebase dependencies then FirebaseInstanceIdService error is coming – Pitchai Mari Jan 23 '20 at 16:46

Update all your firebase dependencies to the latest version. Also after you update, you need to update to androidx and use compileSdkVersion 28.

Also related to firebaseinstanceid, you need check the following:

What to use now that FirebaseInstanceId.getInstance().getToken() is deprecated
