Shared preferences

Android Shared Preferences Overview Android stores Shared Preferences settings as XML file in shared_prefs folder under DATA/data/{application package} directory . The DATA folder can be obtained by calling Environment.

You can use preferences. edit(). remove(“key”). commit() to delete saved values from shared preferences.

Shared preferences allow you to store small amounts of primitive data as key/value pairs in a file on the device . To get a handle to a preference file, and to read, write, and manage preference data, use the SharedPreferences class. The Android framework manages the shared preferences file itself.

SharedPreferences are used in android to store some data presistently (i.e. after closing of application, it will persist). If you want to store few amount of data then you can go for SharedPreferences rather than going for Sqlite and all.In that case SharedPreferences are useful.29 Mar 2013
