Cannot resolve symbol default_web_client_id in Firebase's Android Codelab

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_client_id

And I didn't know how to solve it, since I didn't know the value of
or what it is. It is in the

protected void onCreate(Bundle savedInstanceState) {
mFirebaseAuth = FirebaseAuth.getInstance();

// Assign fields
mSignInButton = (SignInButton) findViewById(R.id.sign_in_button);

// Set click listeners

// Configure Google Sign In
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)

I have no idea what it is, what's its value is, and why is it giving me this error. I haven't changed anything so far except for adding the
. I have added my SHA-1 and enabled Google in the console.

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.
