Simple Android APP that Call a RESTservice

I need a simple app for android that has the following functionality.

.- It should populate a combo box from data retrieved from a REST webservice.

.- the user selects the number from the combo box

.- the user writes some text on a textbox

.- the user clicks on a 'send' button

.- the app uses another REST service to send the message

.- the app shows success or failed based on the response from the message

Im attaching a mockup from the interface ( just to give an idea) and the use case flow.

The application should be completely configurable:

.- the REST services URIs should be configurable ( you won't have the definitive ones).

.- the app should authenticate with an APP key, also configurable ( you won't have it)

You should deliver the source code and instructions to compile it here as we will configure it before installing it on the handset.

Skills: Android, Java, Mobile App Development, RESTful, Software Architecture
