Using disableKeyguard and reenableKeyguard to lock and unlock

Question

If user unlocks a screen by dragging (without using my app) then my application will not lock !. How to prevent this issue? How to fix this bug? plz help me.

Is there any other way to lock and unlock ?

Answer 1

reenableKeyguard

void reenableKeyguard() Reenable the keyguard. The keyguard will reappear if the previous call to disableKeyguard() caused it to be hidden. A good place to call this is from onPause() Note: This call has no effect while any DevicePolicyManager is enabled that requires a password.

This method requires the caller to hold the permission DISABLE_KEYGUARD.

Your app has to be the one to call disableKeyguard() first, else you cannot lock it using reenableKeyguard()
