Android studio - Change firebase project for an android app

Question

I need to change the firebase project connected to my android app in development.

What I've done - I created a new firebase project, added my app, added the necessary sha 1 keys and downloaded the google_services.json file and replaced the content of the file with that in my android studio project.

The issue now is that the android project is still connected to my old firebase project.

What am I not doing right pls

Answer 1

Thank you all for your effort. Rebuilding the project fixed the issue.
