Hi All,

In Android 2.2 there is an option to lock the screen using numeric
PIN. Any idea which API it uses?

Because I want to implement the same concept to lock an application.
Meaning user have to enter the PIN to open the application. Even if
the phone is restarted, the PIN have to be used to open the
application.

Can this be done? Any ideas?

Thanks In Advance,
Perumal
