java - GoogleSignInResult isSuccess 失败

Question

我想为我的应用程序使用 Google 登录，但我总是收到消息 Status{statusCode=unknown status code: 12500, resolution=null 并且登录失败。有人知道问题出在哪里吗？

这是我的 Activity :

public class GruppenActivity extends AppCompatActivity implements
    GoogleApiClient.OnConnectionFailedListener,
    View.OnClickListener {

    private static final String TAG = "SignInActivity";
    private static final int RC_SIGN_IN = 9001;

    private GoogleApiClient mGoogleApiClient;
    private TextView mStatusTextView;
    private ProgressDialog mProgressDialog;

    private LernAppDB db;
    private SQLiteDatabase sqlDatabase;

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

        // Views
        mStatusTextView = (TextView) findViewById(R.id.status);

        // Button listeners
        findViewById(R.id.sign_in_button).setOnClickListener(this);
        findViewById(R.id.sign_out_button).setOnClickListener(this);
        findViewById(R.id.disconnect_button).setOnClickListener(this);

        db = new LernAppDB(this);
        sqlDatabase = db.getReadableDatabase();


        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .requestIdToken(getString(R.string.server_client_id))
            .requestServerAuthCode(getString(R.string.server_client_id))
            .build();

        mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this , this )
            .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 onStart() {
        super.onStart();

        OptionalPendingResult<GoogleSignInResult> opr = Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);
        if (opr.isDone()) {
            Log.d(TAG, "Got cached sign-in");
            GoogleSignInResult result = opr.get();
            handleSignInResult(result);
        } else {

            showProgressDialog();
            opr.setResultCallback(new ResultCallback<GoogleSignInResult>() {
                @Override
                public void onResult(GoogleSignInResult googleSignInResult) {
                    hideProgressDialog();
                    handleSignInResult(googleSignInResult);
                }
            });
        }
    }

    @Override

需要检查的几件事:

1. 在 Firebase Console. 中检查您正确的 SHA 证书指纹

2. 检查 Google API Console. 中的以下警告

• 如果您看到该错误，您需要在 OAuth 同意屏幕 标签中选择支持电子邮件，如下例所示。

选择支持电子邮件后，警告消失了。它开始工作了。
