Answer 1

Get your Editor and call clear() something like this: Edit: as the user DDoSAttack mentioned. There are two ways of getting SharedPreferences

1: getting default SharedPreferences

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(con);

2: getting specific SharedPreferences

SharedPreferences prefs = Context.getSharedPreferences("FileName", Context.MODE_PRIVATE);

and here is how you'll clear it.

public void clear()
{
     SharedPreferences prefs; // here you get your prefrences by either of two methods
     Editor editor = prefs.edit();
     editor.clear();
     editor.commit();
}

Answer 2

If you want to wipe all the data in a preference file call clear() from the SharedPreferences.Editor instance

Answer 3

Use SharedPreferences.Editor clear() method.

See Documentation

SharedPreferences preferences = getPreferences(0);
        SharedPreferences.Editor editor = preferences.edit();

        editor.clear();
        editor.commit();
