Android LockScreen Widget

Question

Can we show any widget on the lock screen as per the latest android sdk? or How we can draw a layout on lockscreen?

Reference Application: https://play.google.com/store/apps/details?id=app.medicalid.free

This application show icon on lock screen and show another activity on tapping the icon without unlocking the device.

How we can achieve this functionality?

This question isn't very clear. A quick look at that page suggests to me that they're creating their own "lock screen" to show a widget, or just using a notification. The second image shows something that is not the standard Android lock screen. — Ryan M

I installed your example app and if you want to show activity on the lock screen you can use this code:

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1)
        {
            setShowWhenLocked(true);
            setTurnScreenOn(true);
            KeyguardManager keyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
            if(keyguardManager!=null)
                keyguardManager.requestDismissKeyguard(this, null);
        }
        else
        {
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD |
                    WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED |
                    WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
        }
