I created new debug SHA1 key using following steps and replaced SHA1 key in my project settings. it worked for me.
-Open Your Project.
-Click on File menu -> New -> Click on Google -> Select Google Maps Activity -> Click on Finish. -Android studio would generate automatic google_maps_api.xml file.
-You can get debug SHA1 key in this file.

Replace this SHA1 key in project settings, Then download new google-services.json from settings and replace it in your project as your certificate_hash and client_id will change.
