Android + Firebase-无法将Google帐户连接到我的应用

Question

我正在尝试将用户的Google帐户链接到我的应用。按登录按钮时，将显示您的帐户屏幕，但是当我选择一个时，什么也没有发生。只是进度条永远运行。 这是我的代码：

我已将Firebase正确链接到我的应用程序，并且还磨碎了使用Internet访问我的应用程序的权限。

这是我的主要活动：

static final int GOOGLE_SIGN = 123;
FirebaseAuth mAuth;
Button btnLogin, btnLogout;
ImageView iv;
ProgressBar progressBar;
GoogleSignInClient inClient;

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

        btnLogin = findViewById(R.id.Login);
        btnLogin.setOnClickListener(v -> SignInGoogle());
        btnLogout = findViewById(R.id.Logout);
        btnLogout.setOnClickListener(v -> Logout());
        iv = findViewById(R.id.iv);
        progressBar = findViewById(R.id.progress);

        mAuth = FirebaseAuth.getInstance();
        GoogleSignInOptions inOptions = new GoogleSignInOptions
                .Builder()
                .requestIdToken(getString(R.string.default_web_client_id))
                .requestEmail()
                .build();

        inClient = GoogleSignIn.getClient(getApplicationContext(), inOptions);

    }

    void SignInGoogle(){
        progressBar.setVisibility(View.VISIBLE);
        Intent signIntent = inClient.getSignInIntent();
        startActivityForResult(signIntent, GOOGLE_SIGN);
    }

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

        if(requestCode == GOOGLE_SIGN) {
            Task<GoogleSignInAccount> taskLogin = GoogleSignIn.getSignedInAccountFromIntent(data);
            try {
                GoogleSignInAccount acc =  taskLogin.getResult(ApiException.class);
                if (acc != null){
                    firebaseAuthWithGoogle(acc);
                }

            } catch (ApiException e) {
                Log.w("TAG", "Google SignIn failed!", e);
            }
        }
    }

    private void firebaseAuthWithGoogle(GoogleSignInAccount acc) {

        Log.d("TAG", "firebaseAuthWithGoole: " + acc.getId());

        AuthCredential credential = GoogleAuthProvider.getCredential(acc.getIdToken(), null);

        mAuth.signInWithCredential(credential).addOnCompleteListener((Executor) getApplication(), task -> {

            if(task.isSuccessful()) {
                progressBar.setVisibility(View.INVISIBLE);
                Log.d("TAG", "signin success");

                FirebaseUser user = mAuth.getCurrentUser();

                Toast.makeText(getApplicationContext(), "SignIn Success!", Toast.LENGTH_LONG).show();

            }
            else {
                progressBar.setVisibility(View.INVISIBLE);
                Log.w("TaG", "signin failure", task.getException());

                Toast.makeText(getApplicationContext(), "SignIn Failed!", Toast.LENGTH_LONG).show();
            }

        });
    }

    void Logout(){

        FirebaseAuth.getInstance().signOut();
        inClient.signOut().addOnCompleteListener((Activity) getApplicationContext(), task -> Toast.makeText(getApplicationContext(), "Logout successfull!", Toast.LENGTH_LONG).show());

    }

以下是我在Logcat中发现的警告： （RanksActivity是我要连接到Google的活动）
