Answer 1

Add latest version of google analytics in module level gradle file as follows :-

implementation 'com.google.android.gms:play-services-analytics:16.0.4'

use implementation instead of compile as compile is deprecated from gradle 4.0 and above

For l atest versions of Google Play Services

Answer 2

Register your project on firebase console. Download the google-services.json file and put it in app folder and run the app. If it still does not work then try to remove the restriction from both the consoles and rerun the app.
