Getting 'E/TokenRequestor: You have wrong OAuth2 related configurations. Detailed error: INVALID_AUDIENCE' even after providing accurate client IDs

Question

I have provided GoogleSignIn option in my app.

Here's my code:

public class SignupActivity extends AppCompatActivity {

    private static final int RC_SIGN_IN = 1;
    GoogleApiClient mGoogleApiClient;
    FirebaseAuth mAuth;
    TextView appName;
    ProgressDialog signinProgressDialog;
    CoordinatorLayout coordinatorLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_signup);
//        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
//        setSupportActionBar(toolbar);

        signinProgressDialog = new ProgressDialog(SignupActivity.this);

        coordinatorLayout = (CoordinatorLayout) findViewById(R.id.signupCoordinatorLayout);

        // Configure Google Sign In
        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestIdToken(getString(R.string.o_auth_client_id))
                .requestEmail()
                .requestProfile()
                .requestId()
                .build();

        // Build a GoogleApiClient with access to the Google Sign-In API and the
        // options specified by gso.
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .enableAutoManage(this /* FragmentActivity */, new GoogleApiClient.OnConnectionFailedListener() {
                    @Override
                    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

                    }
                } /* OnConnectionFailedListener */)
                .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                .build();

        mAuth = FirebaseAuth.getInstance();

        findViewById(R.id.sign_in_button).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (isNetworkAvailable()) {
                    signinProgressDialog.setMessage("Signing in...");
                    signinProgressDialog.show();
                    signIn();
                } else {
                    Snackbar snackbar = Snackbar
                            .make(coordinatorLayout, "No internet connection!", Snackbar.LENGTH_LONG);
                    snackbar.show();
                    signinProgressDialog.dismiss();
                }
            }
        });

    }

    private void signIn() {
        Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
        startActivityForResult(signInIntent, RC_SIGN_IN);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
        if (requestCode == RC_SIGN_IN) {
            GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
            if (result.isSuccess()) {
                // Google Sign In was successful, authenticate with Firebase
                GoogleSignInAccount account = result.getSignInAccount();
                firebaseAuthWithGoogle(account);
            } else {
                // Google Sign In failed, update UI appropriately
                // ...
                Snackbar snackbar = Snackbar
                        .make(coordinatorLayout, "Error signing in!", Snackbar.LENGTH_LONG);
                snackbar.show();
                signinProgressDialog.dismiss();
            }
        }
    }

    private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
        Log.d("firebaseAuthWithGoogle", "firebaseAuthWithGoogle:" + acct.getId());

        AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
        mAuth.signInWithCredential(credential)
                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        Log.d("signin_successful", "signInWithCredential:onComplete:" + task.isSuccessful());

                        Intent mainActivityIntent = new Intent(SignupActivity.this, MainActivity.class);
                        mainActivityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                        mainActivityIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
                        startActivity(mainActivityIntent);
                        signinProgressDialog.dismiss();

                        // If sign in fails, display a message to the user. If sign in succeeds
                        // the auth state listener will be notified and logic to handle the
                        // signed in user can be handled in the listener.
                        if (!task.isSuccessful()) {
                            Log.w("signin_unsuccessful", "signInWithCredential", task.getException());
                            Toast.makeText(SignupActivity.this, "Authentication failed.",
                                    Toast.LENGTH_SHORT).show();
                            signinProgressDialog.dismiss();
                        }
                        // ...
                    }
                });
    }

    @Override
    public void onBackPressed() {
        finish();
        super.onBackPressed();
    }

    private boolean isNetworkAvailable() {
        ConnectivityManager connectivityManager
                = (ConnectivityManager) SignupActivity.this.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
        return activeNetworkInfo != null && activeNetworkInfo.isConnected();
    }
}

I have 2 client IDs, one is Web client and another is Android client.

I have checked my client id's with my google-services.json file and my project on console.developers.google.com They all are matching.

But I'm still getting this error: E/TokenRequestor: You have wrong OAuth2 related configurations, please check. Detailed error: INVALID_AUDIENCE 06-27 12:40:14.651 4443-4484/? D/AuthAccountOperation: id token request failed.

What could possibly be causing this error?

Is it so that my app is no longer connected to my app on my console or is it something else?

Please let me know.

You need to add SHA fingerprint for each android app on your project settings. If you are using Firebase, edit the below link with your project's name and then add the fingerprint for your app.
