AWS凭证无法从android示例应用程序正常工作

Question

I am using the sample app provided from the AWS MOBILE HUB and when I run it works. But whenever i copy the amazonaws folder to my project I get an error with regards to the credentials. This the error i get when i try to run a query to dynamodb

    Caused by: com.amazonaws.AmazonServiceException: User: arn:aws:sts::033145769257:assumed-role/getitdelivery_unauth_MOBILEHUB_927752501/CognitoIdentityCredentials is not authorized to perform: dynamodb:Query on resource: arn:aws:dynamodb:us-east-1:033145769257:table/getitdelivery-mobilehub-927752501-Deliveries/index/Todays_Order (Service: AmazonDynamoDB; Status Code: 400; Error Code: AccessDeniedException; Request ID: JEDMKDQ6JMOTVPIMF85VJHSMGFVV4KQNSO5AEMVJF66Q9ASUAAJG)

Answer 1

You should take a look at your IAM Policy. Mobile Hub configures all of this for you with their generated sample application, but since you copied some things to your own project, you might need to update the policy so that your unauth role has permission to do: dynamodb:Query on resource: arn:aws:dynamodb:us-east-1:033145769257:table/getitdelivery-mobilehub-927752501-Deliveries/index/Todays_Order .

An example of what the policy should look like is found here: http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/using-identity-based-policies.html
