Shared preferences can also be managed through preference activities. These are activities with an automated user interface that’s managed by the framework. You define these preferences in an XML file, similar to an XML menu file, and then access the values with Java code. You then manage the settings with an activity that loads a single fragment; the fragment does the actual work of managing the preferences user interface.
