I am trying to set some attributes in marketing cloud using the addAtribute method: (http://salesforce-marketingcloud.github.io/JB4A-SDK-Android/features/attributes.html)
There it says that it is possible to set any attribute you want: (Add any attributes you save with the SDK to your Marketing Cloud contact record in advance so that the Marketing Cloud can connect the values sent by the SDK to the correct contact fields.)
The problem is that, using this method, the only fields I am able to set are those from MobilePush Demographics. If I try to set any other attribute, nothing happens. If I set an attribute that does not exist, it is saved within the sdk but it is not created in marketing cloud.
Is it possible to set attributes from any data extension or create new ones using that method?
