     53         // However that's not easy to do.  It's not just a matter of setting
     54         // the FLAG_SHOW_WHEN_LOCKED and FLAG_DISMISS_KEYGUARD flags on our
     55         // window, since we're a Dialog (not an Activity), and the framework
     56         // won't ever let a dialog hide the keyguard (because there could
     57         // possibly be stuff behind it that shouldn't be seen.)

     61         // a SIM network unlock PIN.  That's not ideal, but still OK.
