android - close an activity forever on bottun click -

my android app has users' guide activity should start in first run. has button. wanna use button close activity forever. used code:

    button b1001 = (button) findviewbyid(r.id.button1001);     b1001.setonclicklistener(new onclicklistener() {          @override         public void onclick(view arg0) {             // todo auto-generated method stub             startactivity(new intent(splash.this, mainactivity.class));finish();           }     }); 

it doesen't work. heard should use sharedpre/something/ can't. need sample code. thnx

refer link: http://developer.android.com/guide/topics/data/data-storage.html

it's quite clear , doesn't require extensive android knowledge implement. storing value first time run "tutorial", , next time user runs app, "tutorial" not display.

so, used save preferences:

sharedpreferences settings = getsharedpreferences(prefs_name, 0); sharedpreferences.editor editor = settings.edit(); editor.putboolean("silentmode", msilentmode);   editor.commit(); 

and used retrieve stored:

sharedpreferences settings = getsharedpreferences(prefs_name, 0); boolean silent = settings.getboolean("silentmode", false); 

hope helps!
