Is quitting an application frowned upon?

_x000D_ _x000D_ Moving on in my attempt to learn Android, I just read the following: Question: Does the user have a choice to kill the application unless we put a menu option in to kill it? If no such option exists, how does the user terminate the application? Answer: (Romain Guy): The user doesn't, the system handles this automatically. That's what the activity lifecycle (especially onPause/onStop/onDestroy) is for. No matter what you do, do not put a "quit" or "exit" application button. It is useless with Android's application model. This is also contrary to how core applications work. Hehe, for every step I take in the Android world I run into some sort of problem =( Apparently, you cannot quit an application in Android (but the Android system can very well totally destroy your app whenever it feels like it). What's up with that? I am starting to think that it's impossible to write an app that functions as a "normal app" - that the user can quit the app when he/she decides to do so. That is not something that should be relied upon the OS to do. The application I am trying to create is not an application for the Android Market. It is not an application for "wide use" by the general public, it is a business app that is going to be used in a very narrow business field. I was actually really looking forward to developing for the Android platform, since it addresses a lot of issues that exist in Windows Mobile and .NET. However, the last week has been somewhat of a turnoff for me... I hope I don't have to abandon Android, but it doesn't look very good right now =( Is there a way for me to really quit the application?
