Cannot resolve symbol default_web_client_id in Firebase's Android Codelab

Question

I am trying to learn Firebase, so I went through the Android Codelab. The project they gave me however, had an error:

Cannot resolve symbol default_web_cl

Answer 1

Sometimes there is issue while parsing google-services.json. I have reported this issue with to concerned team.

Meanwhile follow below step to fix this issue to get going further -

1) Open google-services.json file -> client -> oauth_client -> client_id

2) Copy this client ID and hardcode this .requestIdToken("your ID")

It would allow to request "IdToken" via GoogleSignInAccount post successful google login and to authorize your credential with firebase.

EDIT

Try deleting and recreating the project and re-importing new google-service.jsonin your Android project
