How to detect/identify if device Lock Screen setting is set to None?

问题

I need to check before enabling my application if the device has no security defined on setting.

Can't have set: Pattern, PIN, Password and even Swipe.

Does anyone know a way to check if the lock screen setting is not enabled?

Alternately, can we check which of the above lock screen settings is enabled?

Thanks!

You can use KeyguardManager - it's isSecureMethod() should return false in Your case. http://developer.android.com/reference/android/app/KeyguardManager.html
