我试图从https://github.com/awslabs/aws-sdk-android-samples/blob/master/AndroidPubSub/README.md运行示例。 我已更改PoolId 、 End Server和Policy Name 。 我收到以下异常。
Exception occurred when generating new private key and certificate. com.amazonaws.AmazonServiceException: 1 validation error detected: Value 'us-west-2_something' at 'identityPoolId' failed to satisfy constraint: Member must satisfy regular expression pattern: [\\w-]+:[0-9a-f-]+ (Service: AmazonCognitoIdentity; Status Code: 400; Error Code: ValidationException; Request ID: f7c3924a-e847-11e6-8508-ab41b4890740)
