Android Question

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

Screen lock have some good security mechanism. (like pin, password, pattern...)

My AP would like to have a similar security mechanism.

Is it possible to invoke screen lock security mechanism?

(so my AP just need to know the result and does not need to handle security by itself)


I found a way to do that, for someone reference

//put below source code in where you want to launch password UI  
km = (KeyguardManager) getSystemService(context.KEYGUARD_SERVICE);  
if(km.isKeyguardSecure()) {  
    Intent i = km.createConfirmDeviceCredentialIntent(null, null);  
    activity.startActivityForResult(i, 1234);  

// call back when password is correct  
protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == 1234) {  
        if (resultCode == RESULT_OK) {  
            //do something you want when pass the security
