Hit an issue when I copied the mobile-services.json from the UI into the android showcase app, which then crashed.
I only had the metrics service 'bound' to the client app, so it was missing all other services.
However, I've worked around this for now by modifying the checked in mobile-services.json to include the metrics config, rather than copying the whole file from the openshift web console.
See AEROGEAR-3060 where this issue in the android showcase app will be fixed.
