I have an application that requires to detect the previous state of the key-guard before calling disableKeyguard() or reenableKeyguard(), set by the user! is there any way of accomplishing this task?
From documentation
Use
((KeyguardManager)getSystemService(Context.KEYGUARD_SERVICE)).isKeyguardLocked()
