憑據提供程序未授權的例外AWS安卓SDK

我試圖使用聯合身份驗證的AWS IoT上的已驗證用戶發佈和訂閱。直到我不斷收到錯誤CognitoCachingCredentialsProvider: Failure to get credentials憑據提供程序未授權的例外AWS安卓SDK

我擡頭看看here。但他們提供的片段不再被Facebook使用。我該如何解決這個問題？

的Android代碼：

public void IntializeAwsIot() { 
    clientId = "us-east-1:fcbd66e0-***************"; 

    // Initialize the AWS Cognito credentials provider 
    credentialsProvider = new CognitoCachingCredentialsProvider(
      getApplicationContext(), // context 
      AWSConfiguration.AMAZON_COGNITO_IDENTITY_POOL_ID,// Identity Pool ID 
      AWSConfiguration.AMAZON_COGNITO_REGION // Region 
    ); 

    Region region = Region.getRegion(AWSConfiguration.AMAZON_COGNITO_REGION); 
    // MQTT Client 
    mqttManager = new AWSIotMqttManager(clientId, CUSTOMER_SPECIFIC_ENDPOINT); 


    // The following block uses IAM user credentials for authentication with AWS IoT. 
    //awsCredentials = new BasicAWSCredentials("ACCESS_KEY_CHANGE_ME", "SECRET_KEY_CHANGE_ME"); 
    //btnConnect.setEnabled(true); 

    // The following block uses a Cognito credentials provider for authentication with AWS IoT. 
    new Thread(new Runnable() { 
     @Override 
     public void run() { 
      awsCredentials = credentialsProvider.getCredentials(); 
      Connect(); 
     } 
    }).start(); 
}

錯誤：

的問題是有一個在Cognito緩存任何憑據。所以我們需要保存適當的憑證，以便獲取憑證功能。

我們需要添加以下內容。

Map<String, String> logins = new HashMap<String, String>(); 
    logins.put("graph.facebook.com", AccessToken.getCurrentAccessToken().getToken()); 
    credentialsProvider.setLogins(logins);
