Mark, I'm almost certain that I'm doing something wrong. I would even dare to venture that I'm taking the wrong approach entirely. I don't know what I don't know.
My plan for the Connection Service is to manage the connection to the remote server entirely in the background. I am planning for the Service to detect server availibility, handle Wifi - 3g transitions, bad server IP, etc. It works to keep the connection alive. No matter the status of the Connection, I want the Service to run in the background and provide a mechanism for the Activities that bind to it to check for a valid Connection. (static boolean?) Then I'll leave the responsiblity of taking the appropriate action for the User to the Activity. Additionally, if no Activities are bound to the Service, it provides information to the User via Notifications. Yes, the Connection extends Thread. If I start a Thread in an Activity, does that Thread need to complete execution before I can transition to the next Activity?
