GPS/Bluetooth Android Application

I need help with my own practice project of developing a simple Android App with both server and mobile components. The application will involve information being shared between clients and will utilize messaging on the server and either location-based services (any 1), Bluetooth, or near field communication on clients. The system should include the following components: 1) Server Components that make a functional server application to support communication between multiple mobile clients. 2) Server Messaging where either Enterprise Messaging or Brokerless Messaging is used to communicate between some of the server-side components. 3) Mobile Components make a functional mobile application with a user interface and communication with the server. 4) Mobile Features which utilize location-based services, Bluetooth, and/or near field communication. The user interface doesn't need to be very nice. just as long as it works.
