java - onActivityResult总是返回未授权

Question

我试图让用户登录该应用，以便能够使用 Google Drive API，但在我的 ActivityResults 中，我总是收到 else 语句，这意味着该用户未获得授权或登录失败。为什么会这样？我已关注the official docs .

这是我的代码:

private static final int REQUEST_CODE_SIGN_IN = 0;
    private DriveClient mDriveClient;
    private DriveResourceClient mDriveResourceClient;

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



    private void initializeDriveClient(GoogleSignInAccount signInAccount) {
        mDriveClient = Drive.getDriveClient(getApplicationContext(), signInAccount);
        mDriveResourceClient = Drive.getDriveResourceClient(getApplicationContext(), signInAccount);
    }

    /**
     * Starts the sign-in process and initializes the Drive client.
     */
    private void signIn() {
        Set<Scope> requiredScopes = new HashSet<>(2);
        requiredScopes.add(Drive.SCOPE_FILE);
        requiredScopes.add(Drive.SCOPE_APPFOLDER);
        GoogleSignInAccount signInAccount = GoogleSignIn.getLastSignedInAccount(this);
        if (signInAccount != null && signInAccount.getGrantedScopes().containsAll(requiredScopes)) {
            initializeDriveClient(signInAccount);
        } else {
            GoogleSignInOptions signInOptions =
                    new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                            .requestScopes(Drive.SCOPE_FILE)
                            .requestScopes(Drive.SCOPE_APPFOLDER)
                            .build();
            GoogleSignInClient googleSignInClient = GoogleSignIn.getClient(this, signInOptions);
            startActivityForResult(googleSignInClient.getSignInIntent(), REQUEST_CODE_SIGN_IN);
        }
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {

            case REQUEST_CODE_SIGN_IN:
                if (resultCode == Activity.RESULT_OK) {
                    // App is authorized, you can go back to sending the API request

                    Log.e("SignIn", "App autorizada");
                } else {
                    // User denied access, show him the account chooser again
                    Log.e("SignIn", "App No Autorizada");
                    finish();
                }
                break;
        }
        super.onActivityResult(requestCode, resultCode, data);
    }

解决了我自己的问题，将 SHA1 和包名称粘贴到我的 Google 控制台中的凭据中，看来我对凭据做了一些错误的操作。
