edited: reading sharedpreferences faster reading small database?

use sharedpreferences, private part of application save values permanently, untill user reinstall (clear data) application. shared preferences works this

// save string in sharedpreferences sharedpreferences settings = preferencemanager.getdefaultsharedpreferences(getapplicationcontext());                     sharedpreferences.editor editor = settings.edit();                     editor.putstring("some_key", string); // here string value want save                     editor.commit();                      // restore string in sharedpreferences  sharedpreferences settings = preferencemanager.getdefaultsharedpreferences(getapplicationcontext()); string = settings.getstring("some_key", ""); 

obviously can save int boolean etc instead of string
