点击“SIGIN in with Google”按钮后卡住了[重复]

Question

所以我一直试图让与谷歌Signin作为我的应用程序的Signin选项。当我点击sigin按钮时，应用程序会显示availabe电子邮件列表，但只要我点击任何电子邮件，应用程序就不会让我登录。我尝试了几乎所有的方法，包括在firebase中添加SHA-1键，替换新的google-services.json文件。我已经重新检查了我的代码，但我一定漏掉了什么。请帮我找出我的错误

public class User_login extends AppCompatActivity {


    private static final int RC_SIGN_IN = 123;
    private FirebaseAuth mAuth;
    private GoogleSignInClient mGoogleSignInClient;



    @Override
    protected void onStart() {
        super.onStart();

        FirebaseUser user = mAuth.getCurrentUser();
        if(user != null){
            Intent intent = new Intent(getApplicationContext(), home_user.class);
            startActivity(intent);
        }

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_user_login);

        mAuth = FirebaseAuth.getInstance();

    
    // ________________SIGN IN WITH GOOGLE _____________//

        createRequest();

        findViewById(R.id.google_signIn).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                signIn();
            }
        });
    }

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

        mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
    }

    private void signIn() {
        Intent signInIntent = mGoogleSignInClient.getSignInIntent();
        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) {
            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("DEBUG", "Google sign in failed", e);
                Toast.makeText(User_login.this,"Google signin failed",Toast.LENGTH_LONG).show();
            }
        }
    }

    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("DEBUG", "signInWithCredential:success");

                            FirebaseUser user = mAuth.getCurrentUser();
                            Intent intent = new Intent(getApplicationContext(), home_user.class);
                            startActivity(intent);

                        } else {
                            Toast.makeText(User_login.this, "sorry something went wrong, please retry",Toast.LENGTH_LONG).show();
                            // If sign in fails, display a message to the user.
                            //Log.w(TAG, "signInWithCredential:failure", task.getException());

                        }
                    }
                });
    }



}

在Firebase检查你必须启用谷歌登录吗？

转到firebase身份验证，并在sigin方法中启用google登录
