I intend to have a server, which I will access using an Android phone as a client. The server will hold a database of authorized users.
How would I code to allow authorized users to communicate securely between the two?

Thanks.

I can't find any built-in functionality....
use webservice (SOAP) perhaps?

I know how to talk to the server. I just don't know how to do a logon and talk securely.
