Where should I define SharedPreferences?

In my app, I'm trying to get SharedPreferences to work. However, the settings are located in a fragment, but the settings defined in the fragment effect each activity. With that said, I'm not sue a to where I define my SharedPreferences object, in the fragment (because thats where you tweak the settings), or in my MainAcitvity (because, obviously, that's the first thing you see when you open the app, and SharedPreferences will be used in every activity)?

Two popular ways to do it are: 1) Open SharedPreferences when and where you need them. Your SharedPreferences should have particular names to access them so there's no need to keep it open in the settings activity/fragment. Another is to extend the Application class for your app and put getter/setter methods for your settings there.
