当应用程序被销毁时，alarmManager不会唤醒我的代码么？

Question

我创建了一个提醒系统，它正常工作，当我关闭它运行的应用程序时。但是当我通过关闭所有最近的应用程序来销毁应用程序时，警报管理器不会唤醒应用程序，这是我的代码：

清单：

<receiver android:name=".TimeAlarm" />

方法：

public void addAlarm(int id, int year, int month, int day, int hour, int minute) {
        Calendar cal = Calendar.getInstance();
        cal.set(year, month, day, hour, minute);

        Intent intent = new Intent(this, TimeAlarm.class);
        PendingIntent operation = PendingIntent.getBroadcast(this, id, intent, PendingIntent.FLAG_ONE_SHOT);
        am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), operation);
    }

班主任：

public class TimeAlarm extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        int notificationID = 3;
        NotificationManager notificationManager;
        Notification myNotification;

        Intent myIntent = new Intent(context, MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getService(context, 0, intent, 0);

        myNotification = new NotificationCompat.Builder(context)
                .setContentTitle("Exercise of Notification!")
                .setContentText("Do Something...")
                .setTicker("Notification!")
                .setWhen(System.currentTimeMillis())
                .setContentIntent(pendingIntent)
                .setDefaults(Notification.DEFAULT_SOUND)
                .setAutoCancel(true)
                .setSmallIcon(R.drawable.ics_close)
                .build();

        notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(notificationID, myNotification);
    }
}

谢谢！
