I am implementing a custom 'swipe to unlock' screen.

If the 'Screen lock' in settings is 'Swipe', my app work properly. In my custom 'swipe to unlock' screen -> User swipe to unlock -> it unlocks phone and go to home screen directly by adding the code below in my activity:

activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);

The problem arises when the 'Screen lock' in settings is 'PIN', the code above does not affect. What I expect is it will bypass the default 'swipe to unlock' screen and go to 'PIN input' screen, so users don't have to swipe twice to enter their PIN.

UPDATE:

It seems that we cannot avoid the default 'swipe to unlock' screen, so I try with another approach that using finger print.

@Override public void onAuthenticationSucceeded(FingerprintManager.AuthenticationResult result) { mCallback.onAuthenticated(); }

Currently, I have to touch to the sensor twice, first to dismiss my lock screen and second for the default lock screen. The next app can dismiss 2 lock screen with only one touch, so I think it is possible to do so.

    You cann't without System Permissions, because next swipe to unlock (with pin), based on System, and on some other device, there willn't be seconds screen, but just PIN. – GensaGames Jun 23 '17 at 18:32
  • @GensaGames it means it is impossible with unrooted devices? – thanhbinh84 Jun 24 '17 at 01:08

    After looking at how gravitybox does it, I've come to the conclusion that there is in fact no way to achieve this without root. Reference https://github.com/GravityBox/GravityBox/blob/marshmallow/src/com/ceco/marshmallow/gravitybox/ModLockscreen.java with settings key PREF_KEY_LOCKSCREEN_DIRECT_UNLOCK – F43nd1r Jun 24 '17 at 21:54

Don’t need to listen to finger print, just register when device is unlocked and dismiss your lock screen: 

void registerUnlockReceiver() {
    IntentFilter i = new IntentFilter(Intent.ACTION_USER_PRESENT);
    registerReceiver(mUserUnlockedReceiver , i);
}

BroadcastReceiver mUserUnlockedReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        unlockAndExit(false);
    }
};
