now, did understend me?

create sharedpreferences way

 sharedpreferences settings = getsharedpreferences(prefs_name, 0);  sharedpreferences.editor editor = settings.edit();  editor.putstring("prefname", value);  editor.commit(); 

get values way

 sharedpreferences settings = getsharedpreferences(prefs_name, 0);  string s = settings.getstring("prefname", "")); 

the last statement means looking value of "prefname" , setting "" if nothing found.

hope helps
