Android 登录时出现AWS Cognito未知错误

当我试图使用android（java）代码在AWS中登录Cognito时，我遇到了一个未知的错误

我已接受IAM中的所有默认角色

注册和确认电子邮件工作正常。这正是我想在authenticationContinuation.continueTask（）之后登录的时候；显示未知错误。有什么想法吗？建议？

原来我用错了poolid duh！ 联邦池中也有一个池id，我使用的是它，而不是用户池中的那个

 public void SignIn(String phoneNumber) {

    final ClientConfiguration clientConfiguration = new ClientConfiguration();

    // Create a CognitoUserPool object to refer to your user pool
    CognitoUserPool userPool = new CognitoUserPool(_context, poolId, _clientId,
            _clientSecret, clientConfiguration);

    CognitoUser user = userPool.getUser(phoneNumber);

    // Callback handler for the sign-in process
    AuthenticationHandler authenticationHandler = new AuthenticationHandler() {

        @Override
        public void onSuccess(CognitoUserSession cognitoUserSession) {
            // Sign-in was successful, cognitoUserSession will contain tokens for the user
            Token = cognitoUserSession.getAccessToken();

        }

        @Override
        public void getAuthenticationDetails(AuthenticationContinuation authenticationContinuation, String userId) {
            // The API needs user sign-in credentials to continue
            AuthenticationDetails authenticationDetails = new AuthenticationDetails(userId, _password, null);

            // Pass the user sign-in credentials to the continuation
            authenticationContinuation.setAuthenticationDetails(authenticationDetails);

            // Allow the sign-in to continue
            authenticationContinuation.continueTask();
        }

        @Override
        public void getMFACode(MultiFactorAuthenticationContinuation multiFactorAuthenticationContinuation) {
            // Multi-factor authentication is required; get the verification code from user
            multiFactorAuthenticationContinuation.setMfaCode("123");
            // Allow the sign-in process to continue
            multiFactorAuthenticationContinuation.continueTask();
        }

        @Override
        public void onFailure(Exception exception) {
            // Sign-in failed, check exception for the cause
            Log.d("error:", exception.getMessage());
            LoginController loginController = new LoginController(_this);
            loginController.NavigateToLogin();

        }
    };

    // Sign in the user
    user.getSessionInBackground(authenticationHandler);

}
