SAP Web IDE and Mobile Service - Build Developer Companion: Failed to Provision the local store

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?

    I believe the issue here is the following: The companion app does not come with the Kapsel offline plugin. So you will only be able to try online scenarios. Here is a list with the plugins supported:

    Hi Christoph,

    The Companion App (and also the Developer Companion that you can build on-demand) are typically online apps that pull the web application into the container from an external source. We cannot support the offline feature for this scenario. Therefore, we don't add the Kapsel offline plugin into the app.

    For developing offline apps, you'll have to use a Packaged App.
