The apis may be called from other threads, including the 128 * {@link com.android.server.input.InputManagerService}'s and {@link android.view.WindowManager}'s. 129 * Therefore, methods on this class are synchronized, and any action that is pointed 130 * directly to the keyguard UI is posted to a {@link android.os.Handler} to ensure it is taken on the UI 131 * thread of the keyguard. 132 */ 133public class KeyguardViewMediator extends SystemUI { 134 private static final int KEYGUARD_DISPLAY_TIMEOUT_DELAY_DEFAULT = 30000;
