Can't connect from Android client: No locations available

I’m new to openMRS so I know if this may sounds like a stupid question. I am trying to implement the android client (https://wiki.openmrs.org/display/projects/OpenMRS+2.x+Android+Client) using my own server. I have installed the openmrs 2.2 and the xforms module but I can’t connect from my android client because I can’t choose a location (as in the example - impatient ward, laboratory etc) and therefore my login button is inactive. Any idea how I can add those locations to my openmrs platform?

@dianadarie, have you set up the rest webservice module on your server? see: configuration options at https://wiki.openmrs.org/display/docs/REST+Module

To setup locations follow: https://wiki.openmrs.org/display/docs/OpenMRS+2.2#OpenMRS2.2-Locationbasedlogin
