Android Amazon DynamoDB 400 Bad Request error

Question

Я пытаюсь реализовать Amazon Dynamo DB в своем приложении для Android. Таблица создана с атрибутами, такими как id (строка), статус (число). Я получаю AmazonClientException как «Невозможно отменить ответ на ошибку». кто-нибудь предлагает мне.

Вот мой код ..

try { 
      AmazonDynamoDBClient ddb = DynamoDB.getInstance(); 

       Map<String, AttributeValue> item = new HashMap<String, AttributeValue>(); 
       item.put("googleid", new AttributeValue().withS("Test")); 
       item.put("status", new AttributeValue().withN("1234")); 

       PutItemRequest putItemRequest = new PutItemRequest("android_news_push", item); 
       PutItemResult putItemResult = ddb.putItem(putItemRequest); 
    } catch (AmazonServiceException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
    } catch (AmazonClientException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
    } 

Мой Исключение:

Похоже, у вас есть проблемы с учетными данными АМС. Проверьте правильность ваших ключей, а также проверьте, разрешает ли контроль доступа эту операцию.
