CognitoSyncDemo: Failed to list records in dataset

Question

I downloaded Amazon's samples: CognitoSyncDemo https://github.com/awslabs/aws-sdk-android-samples/tree/master/CognitoSyncDemo and tried to run it in unauthenticated mode. I followed Amazon's guide: created AWS account; created Identities Pool in Cognito; added roles in IAM.

But when I ran the sample app, populate some data into dataset and tried to sync them, it popup that : Failed due to Failed to list records in dataset: XXX(XXX is my dataset name).

The role policy I created for unauthenticate is as follows:

{
    "Version": "2012-10-17",
    "Statement": [{
        "Action": [
            "mobileanalytics:PutEvents",
            "cognito-sync:*",
            "sns:*"
        ],
        "Effect": "Allow",
        "Resource": [
            "*"
        ]
    }]
}

I am not sure if it was the role's problem.

Does anyone had such problem as well when you ran the CognitoSyncDemo provided by Amazon?

The role policy looks sane. The details you provided are not enough to see what else is causing the problem, so this is a list of things you should verify:

From your Identity Pool in the Cognito Console, go to "Edit Identity Pool" and make sure that "Enable Access to unauthenticated Identities" is checked.
Make sure that the region (US-East or EU-West) in your AWS Console matches the region set in your app's code.
Make sure you have entered the correct roles ARN's in the app's source, together with the identity pool id and your AWS account.
