如何解决“ OAuthException，错误消息：（＃803）您请求的某些别名不存在：YOUR_APP_ID}”

Question

我正在尝试按照https://developers.google.com/identity/sign-in/android/sign-in的指南将Google登录功能集成到我的Android应用中。但是，即使在应用正常运行的情况下，我在“运行”窗口中之前和之后登录时发现以下错误：

“ E / GraphResponse：{HttpStatus：404，错误代码：803，subErrorCode：-1，错误类型：OAuthException，错误消息：（＃803）您请求的某些别名不存在：YOUR_APP_ID}”

我不确定根本原因是什么。有人可以帮忙吗？

致谢， 布莱恩

公共类LoginActivity扩展了AppCompatActivity {

private static String TAG = "TAG LoginActivity";
private static final int RC_SIGN_IN = 205;
private GoogleSignInClient mGoogleSignInClient;
private Context context;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_login);

    context = getBaseContext();

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

    mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
