How to shutdown an Android mobile programmatically?
android
Solution
You could possibly use the PowerManager to make it reboot (this does not guarantee that it'll reboot - OS may cancel it):
http://developer.android.com/reference/android/os/PowerManager.html#reboot(java.lang.String)
It requires the REBOOT permission:

Can you also check your logcat when trying to enable/disable keyguard, and post what's there?
You cannot do this from an ordinary SDK application. Only applications signed with the system firmware signing key can do this
Problem
