I have downloaded my google-services.json and overwritten the previous one. However, nothing solved. Of cause I have these google-services settings in both project and app level build.gradles. The app has already been enabled at Firebase Console. Why isn't my google-services.json's project_id properly read?

implementation platform('com.google.firebase:firebase-bom:28.3.0')
implementation 'com.google.firebase:firebase-analytics'
implementation 'com.google.firebase:firebase-crashlytics'

Solution

I have figured out the cause of this problem.

DO NOT UPDATE TO 'com.google.gms:google-services:4.3.9' though Android Studio suggests to that!

classpath 'com.google.gms:google-services:4.3.9'

I've just reverted it to 4.3.8, the problem is cleared.

Currently, the Google's official document only mentions about 4.3.8. Don't trust Android Studio recklessly.
