Question
I'm encountering an error when using the background-network category with API version 2.4 in the latest Tizen Studio. The error message states:
Invalid content was found starting with element 'background-category'. One of '{"http://tizen.org/ns/packages":label, "http://tizen.org/ns/packages":icon, "http://tizen.org/ns/packages":image, "http://tizen.org/ns/packages":application-service, "http://tizen.org/ns/packages":app-control, "http://tizen.org/ns/packages":category, "http://tizen.org/ns/packages":metadata, "http://tizen.org/ns/packages":permission, "http://tizen.org/ns/packages":datacontrol, "http://tizen.org/ns/packages":eventsystem}' is expected.
This configuration worked fine with older IDE versions, but the new Tizen Studio only raises this error when using API version 2.4. Is this a bug in Tizen Studio? Has anyone found a solution to this issue?
