无法通过Firebase进行身份验证-应用程序在设备上运行而没有警告

Question

这是通过Google项目登录。 我已经连接到Firebase并在那里设置了项目。是的，我已经启用了Google登录方法。

“登录”按钮有效-但这与Toast消息“身份验证失败”

我读了几个小时的代码后可能会过时，这让我很疑惑（我是菜鸟）。

我的登录按钮也有一些奇怪的错误（不影响设备的构建）。

MainActivity.java

    SignInButton button;
    FirebaseAuth mAuth;
    private final static int RC_SIGN_IN = 2;

    GoogleApiClient mGoogleApiClient;
    FirebaseAuth.AuthStateListener mAuthListener;


    @Override
    protected void onStart() {
        super.onStart();
        mAuth.addAuthStateListener(mAuthListener);
    }

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

        button = (SignInButton) findViewById(R.id.googlebtn);
        // Initialize Firebase Auth
        mAuth = FirebaseAuth.getInstance();

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                signIn();
            }
        });

        mAuthListener = new FirebaseAuth.AuthStateListener() {
            @Override
            public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                if (firebaseAuth.getCurrentUser() != null){
                    startActivity(new Intent(MainActivity.this, SecondOne.class));
                }

            }
        };

        // Configure Google Sign In
        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)

           if (result.isSuccess()) {
               // Google Sign In  was succesfull, authenticate with Firebase
               GoogleSignInAccount account = result.getSignInAccount();
               FirebaseAuthWithGoogle(account);
           } else {
               // Google Sign In Failed, update UI appropriatly
               //..
               Toast.makeText(MainActivity.this,"Auth went wrong", Toast.LENGTH_SHORT).show();
           }
        }
    }

    private void FirebaseAuthWithGoogle(GoogleSignInAccount account) {

        AuthCredential credential = GoogleAuthProvider.getCredential(account.getIdToken(), 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
