I've built a mobile developer companion and deployed it to an android device. When the app is started and the local offline store is being provisioned the following error occurs:
"Failed to start the app: Failed to provision the local store: [-10288] Communication with the server failed with status code: 400"
However running a mobile packaged app with the same source code does not result in any error.
As far as I can see there is a difference in the offline service root url which is part of the JavaScript offline store object:
Are there any further settings needed when building and using a developer companion?
