GoogleSignInApi is always faild when trying to sign in

Question

I want to make Google Sign-in Button for my android mobile app. I am using 4 years ago library for making this. But there is a problem. I click to sign-in button. After, I choose my Gmail account. But unfortunately, Sign in is always failed. I have tried too many library versions. And Solutions at stackoverflow.com Such as: Error implementing GoogleApiClient Builder for Android development

Library that I used to:

 implementation 'com.google.android.gms:play-services-auth:17.0.0'

İmplements:

implements GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener

Here is my code:

sign_in_button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {


                sign_In();

            }

            private void sign_In() {
                GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                        .requestIdToken(getString(R.string.default_web_client_id))
                        .requestEmail()
                        .build();

                mGoogleApiClient = new GoogleApiClient.Builder(getApplicationContext())
                        .enableAutoManage(enter_screen.this, enter_screen.this)
                        .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                        .build();
                Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
                startActivityForResult(signInIntent, RC_SIGN_IN);






            }
        });

  @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

    }

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


        if (requestCode == RC_SIGN_IN) {

            GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
            if (result.isSuccess()){
                GoogleSignInAccount account = result.getSignInAccount();
                firebaseAuthGoogle(account);

                Toast.makeText(this, "works", Toast.LENGTH_SHORT).show();
            }else {

                // Here is the problem. It returns me this toast message.

                Toast.makeText(this, "faild", Toast.LENGTH_SHORT).show();


            }

        }

    }

    private void firebaseAuthGoogle(GoogleSignInAccount account) {
        AuthCredential credential = GoogleAuthProvider.getCredential(account.getIdToken(),null);
        firebaseAuth.signInWithCredential(credential)
                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (!task.isSuccessful()){
                            Toast.makeText(enter_screen.this, "Giriş başarısız", Toast.LENGTH_SHORT).show();

                        }else {
                            Intent intent = new Intent(getApplicationContext(), MainActivity.class);
                            startActivity(intent);
                            enter_screen.this.finish();

                        }



                    }
                });


    }


    @Override
    public void onConnected(@Nullable Bundle bundle) {

    }

    @Override
    public void onConnectionSuspended(int i) {

    }

    @Override
    public void onPause() {
        super.onPause();
        mGoogleApiClient.stopAutoManage(enter_screen.this);
        mGoogleApiClient.disconnect();
    }

My console shows me when I try to sign in:

D/AutoManageHelper: starting AutoManage for client 0 true null
    connecting com.google.android.gms.common.api.internal.zabe@ab0a32d

This words.

How can I fix it? I want to log in and record my Gmail address to Firebase authentication.

Answer is here. It can not work because google updated this section.

First of all, add all dependencies to your project:

  implementation platform('com.google.firebase:firebase-bom:31.4.0')

    // Add the dependency for the Firebase Authentication library
    // When using the BoM, you don't specify versions in Firebase library dependencies
    implementation 'com.google.firebase:firebase-auth'

    // Also add the dependency for the Google Play services library and specify its version
    implementation 'com.google.android.gms:play-services-auth:20.4.1'

Global variables:

  private static final String TAG = "GoogleActivity";
    private static final int RC_SIGN_IN = 9001;

    // [START declare_auth]
    private FirebaseAuth mAuth;
    // [END declare_auth]

    private GoogleSignInClient mGoogleSignInClient;

mAuth = FirebaseAuth.getInstance();

Add these codes to your activity:

 GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)

        // Firebase setting kısmında bu anahtarı bulabilirsin.
        .requestIdToken(getString(R.string.default_web_client_id))
        .requestEmail()
        .build();

mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
// [END config_signin]

// [START initialize_auth]
// Initialize Firebase Auth
mAuth = FirebaseAuth.getInstance();
// [END initialize_auth]

Intent signInIntent = mGoogleSignInClient.getSignInIntent();
startActivityForResult(signInIntent, RC_SIGN_IN);

}

// [START on_start_check_user]
@Override
public void onStart() {
    super.onStart();
    // Check if user is signed in (non-null) and update UI accordingly.
    FirebaseUser currentUser = mAuth.getCurrentUser();
    updateUI(currentUser);
}
// [END on_start_check_user]

// [START onactivityresult]
@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) {
        Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
        try {
            // Google Sign In was successful, authenticate with Firebase
            GoogleSignInAccount account = task.getResult(ApiException.class);
            Log.d(TAG, "firebaseAuthWithGoogle:" + account.getId());
            firebaseAuthWithGoogle(account.getIdToken());
        } catch (ApiException e) {
            // Google Sign In failed, update UI appropriately
            Log.w(TAG, "Google sign in failed", e);
        }
    }
}
// [END onactivityresult]

// [START auth_with_google]
private void firebaseAuthWithGoogle(String idToken) {
    AuthCredential credential = GoogleAuthProvider.getCredential(idToken, null);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                        // Sign in success, update UI with the signed-in user's information
                        Log.d(TAG, "signInWithCredential:success");
                        FirebaseUser user = mAuth.getCurrentUser();
                        updateUI(user);
                    } else {
                        // If sign in fails, display a message to the user.
                        Log.w(TAG, "signInWithCredential:failure", task.getException());
                        updateUI(null);
                    }
                }
            });
}
// [END auth_with_google]

// [START signin]
private void signIn() {
    Intent signInIntent = mGoogleSignInClient.getSignInIntent();
    startActivityForResult(signInIntent, RC_SIGN_IN);
}
// [END signin]

private void updateUI(FirebaseUser user) {

}

Lastly don't forget to add your SHA1 Fingerprint to firebase's console project. Here is the tutorial
