在Android AWS中创建新的唯一ID

Question

So I am trying to create a new table in AWS dynamoDB, but I cannot find anywhere in the documentation that shows how to create a unique ID for android. They show how to get the user cognito ID: AWSMobileClient.defaultMobileClient().getIdentityManager().getCachedUserID() , But I am not creating a new user here, I am creating a new Group, so I want a completely unique ID for every table that I create. Does anyone know how I can do this? I have scoured the internet for this but can't seem to find the answer. The answer in objective-c is very simple, which is found using this: [AWSIdentityManager defaultIdentityManager].identityId; , please tell me there is something like this for the android version. Your help is greatly appreciated.

Answer 1

Figured it out. Had to go into my GroupsDO model and add @DynamoDBAutoGeneratedKey above the groupId section, and it would automatically generate a unique id on save.
