我试图从https://github.com/awslabs/aws-sdk-android-samples/blob/master/AndroidPubSub/README.md运行示例。我更改了PoolId，End Server和Policy Name。我正在接受例外。
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)
答案 0 :(得分：1)
您需要转到Cognito console并创建一个Cognito Identity Pool，并将us-west-2_something替换为看起来像us-west-2:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx的实际身份池ID
