Do I need a Service in my android application?

Question

In my Application I have several Activities and a Java class with a thread. This thread continuously receives and sends messages to the web server. The Application is working fine in testing but I am worried that it may not when being used in actual phones. I am afraid that my background thread which continuously interacts with the Server might be killed by Android, while the app is in background.

Do I really need to make my threaded client class a service ? I want to start it when user signs in and stop it when the user logs off from the system.

If I need to do it please suggest some easy tutorial for it.

据我所知，你最好将TimerTask与Timer一起使用，以及任何普通的类或服务都可以满足你的目标。
