This includes queries about the 57 * state of the keyguard, power management events that effect whether the keyguard 58 * should be shown or reset, callbacks to the phone window manager to notify 59 * it of when the keyguard is showing, and events from the keyguard view itself 60 * stating that the keyguard was succesfully unlocked. 61 * 62 * Note that the keyguard view is shown when the screen is off (as appropriate) 63 * so that once the screen comes on, it will be ready immediately. 64 * 65 * Example queries about the keyguard: 66 * - is {movement, key} one that should wake the keygaurd? 67 * - is the keyguard showing? 68 * - are input events restricted due to the state of the keyguard? 69 * 70 * Callbacks to the phone window manager: 71 * - the keyguard is showing 72 * 73 * Example external events that translate to keyguard view changes: 74 * - screen turned off -> reset the keyguard, and show it so it will be ready 75 * next time the screen turns on 76 * - keyboard is slid open -> if the keyguard is not secure, hide it 77 * 78 * Events from the keyguard view: 79 * - user succesfully unlocked keyguard -> hide keyguard view, and no longer 80 * restrict input events. 81 * 82 * Note: in addition to normal power managment events that effect the state of 83 * whether the keyguard should be showing, external apps and services may request 84 * that the keyguard be disabled via {@link #setKeyguardEnabled(boolean)}.
