This includes queries about the 63 * state of the keyguard, power management events that effect whether the keyguard 64 * should be shown or reset, callbacks to the phone window manager to notify 65 * it of when the keyguard is showing, and events from the keyguard view itself 66 * stating that the keyguard was succesfully unlocked. 67 * 68 * Note that the keyguard view is shown when the screen is off (as appropriate) 69 * so that once the screen comes on, it will be ready immediately. 70 * 71 * Example queries about the keyguard: 72 * - is {movement, key} one that should wake the keygaurd? 73 * - is the keyguard showing? 74 * - are input events restricted due to the state of the keyguard? 75 * 76 * Callbacks to the phone window manager: 77 * - the keyguard is showing 78 * 79 * Example external events that translate to keyguard view changes: 80 * - screen turned off -> reset the keyguard, and show it so it will be ready 81 * next time the screen turns on 82 * - keyboard is slid open -> if the keyguard is not secure, hide it 83 * 84 * Events from the keyguard view: 85 * - user succesfully unlocked keyguard -> hide keyguard view, and no longer 86 * restrict input events. 87 * 88 * Note: in addition to normal power managment events that effect the state of 89 * whether the keyguard should be showing, external apps and services may request 90 * that the keyguard be disabled via {@link #setKeyguardEnabled(boolean)}.
