Can app use android security mechanism (pin code, pattern, password...)? -

screen lock have security mechanism. (like pin, password, pattern...)
ap have similar security mechanism.
possible invoke screen lock security mechanism?
(so ap need know result , not need handle security itself)

i found way that, reference

//put below source code in want launch password ui   km = (keyguardmanager) getsystemservice(context.keyguard_service);   if(km.iskeyguardsecure()) {       intent = km.createconfirmdevicecredentialintent(null, null);       activity.startactivityforresult(i, 1234);   }    // call when password correct   @override   protected void onactivityresult(int requestcode, int resultcode, intent data) {       if (requestcode == 1234) {           if (resultcode == result_ok) {               //do want when pass security           }       }   }
