Using the latest build, I am able to add and retrive Attribute names to an account. However, I could not locate corresponding API call to retrieve attribute values against each attribute name. Is there a work-around to this problem?
Unfortunately AccountManager does not provide a message in order to retrieve the values of the account attributes. AccountManager.getAccountAttributes() just returns the names of the required account attributes (like its comment says).
We could add a new method to AccountManager in order to get the value of a given account attribute but for the moment you can try getting a Registration and use Registration.getAttributes to gain access to the values of the account attributes.
FYI, in the next daily build you will find a new AccountManager message that allows you to obtain the value of a given account attribute. The message signature is String getAccountAttribute(String).
