Running a specific code once at 1st run Android -


i want run code once application run 1st time after installation. never again how it

following code here how trying

    protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);      securityprefs.setautosavepattern(this, true);      string settingstag = "appnamesettings";     sharedpreferences prefs = getsharedpreferences(settingstag, 0);     boolean run = prefs.getboolean("run", false);      if (run == false)     {         run = true;     intent intent = new intent(lockpatternactivity.action_create_pattern, null,             this, lockpatternactivity.class);     startactivityforresult(intent, req_create_pattern);       }     else     { intent intent1 = new intent(lockpatternactivity.action_compare_pattern,null,this,lockpatternactivity.class);      startactivityforresult(intent1, req_enter_pattern);     }   }

so problem facing? 

string settingstag = "appnamesettings"; sharedpreferences prefs = getsharedpreferences(settingstag, 0); boolean run = prefs.getboolean("run", false);

your code should work if after running first time have updated shared preference , stored true "run".
