安卓谷歌登录不可用？

所以我的项目遇到的一个问题是通过谷歌登录不能一致工作。即，它适用于我的朋友，而不是我的计算机上的我，尽管它昨天在擦除我的手机之前对我有用（手机已损坏）。我们的登录代码是google登录的标准，问题是我认为结果一直返回false。代码：

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.welcome_screen);
        findViewById(R.id.sign_in_button).setOnClickListener(this);

        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestEmail()
                .build();

        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
                .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                .build();

        SignInButton signInButton = (SignInButton) findViewById(R.id.sign_in_button);
        signInButton.setSize(SignInButton.SIZE_STANDARD);
        signInButton.setScopes(gso.getScopeArray());

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.sign_in_button:
                signIn();
                break;
        }
    }   

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

    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);
            handleSignInResult(result);
        }
    }

    private void handleSignInResult(GoogleSignInResult result) {
        if (result.isSuccess()) {
            // Signed in successfully, show authenticated UI.
            GoogleSignInAccount acct = result.getSignInAccount();

//            mStatusTextView.setText(getString(R.string.signed_in_fmt, acct.getDisplayName()));
            updateUI(acct);
        } else {
            // Signed out, show unauthenticated UI.
            noUpdateUI();
        }
    }

    private void updateUI(GoogleSignInAccount acct) {
        Intent intent = new Intent(getApplicationContext(), HomeScreen.class);

        Bundle bundle = new Bundle();
        bundle.putSerializable("NEW_USER", new ClientUser(acct));
        intent.putExtras(bundle);

        startActivity(intent);
    }


For some reason, the result is false:

    private void noUpdateUI() {
        System.out.println("**** Try again****");
//        mStatusTextView.setText(R.string.signed_out);
        findViewById(R.id.sign_in_button).setVisibility(View.VISIBLE);
    }

我认为我已经正确设置了应用程序的凭据，因为在我擦除手机之前它之前可以在我的桌面上运行。值得注意的是，我的朋友在笔记本电脑上工作时遇到了同样的问题，但在台式机上工作时没有遇到问题。不确定发生了什么；有什么建议么？

我有同样的问题。 我通过执行以下操作解决了这个问题：

1. 我转到我的 build.gradle(app)，在 defaultConfig 中，并将 applicationId 更改为我的包名称（我不知道为什么它最初不一样）。 我从compile 'com.google.android.gms:play-services-auth:8.3.0' to compile 'com.google.android.gms:play-services-auth:8.4.0'确保apply plugin: 'com.google.gms.google-services'位于 build.gradle(app) 的底部，即在依赖项之后

2. 我生成了一个新的 SHA-1 密钥。要生成 SHA-1 密钥，请将其粘贴到您的终端中：keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android然后去你的凭证页面 https://console.developers.google.com/projectselector/apis/credentials并选择您的项目。

3. 在 OAuth 2.0 客户端下，单击您的 Android 客户端密钥。按照指示粘贴您生成的 SHA-1 密钥和包名称。单击保存。

   4. 下载新的 google-services.json 文件并将其粘贴到您的 app/ 目录中。

然后尝试再次登录。希望它能起作用。 欲了解更多信息，请参阅此post https://stackoverflow.com/a/35050443/5604736 and 这也是 https://stackoverflow.com/a/35077016/5604736。它帮助我解决了我的问题
