我的 ReminderService 使用 AlarmManager 通知用户特定时间即将发生的事件。 AlarmManager是否可能通知相同的服务（ReminderService），或者我是否需要启动另一个服务来捕获待处理的意图？到目前为止，这种机制看起来像这样
public class ReminderService extends Service {
// ...
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// ..
/* When the alarm goes off the NotifyService will be started. Is it possible to inform **this**
service (ReminderService) and to handle the alarm? */
Intent alarmIntent = new Intent(this, NotifyService.class);
alarmIntent.putExtra(TodoTask.PARCELABLE_KEY, task);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, alarmIntent, 0);
Calendar calendar = Calendar.getInstance();
Date date = new Date(reminderTimeStamp*1000);
calendar.setTime(date);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
}
}
答案 0 :(得分：0)
您可以使用相同的Service（或其他组件）来接收警报。但是，并不是说在低功率时不能保证您的报警按计划交付。使用WakefulReceiver或您自己的BroadcastReceiver和唤醒锁的组合来获取Service。有关电源状态和警报的详细信息，请参阅this article。
另请注意，从Android Marshmallow开始，如果设备处于打盹模式，您的唤醒锁将被忽略。在Doze中的某个时间，您还需要执行其他操作来唤醒设备。

到此：
Intent alarmIntent = new Intent(this, NotifyService.class);
这样Intent alarmIntent = new Intent(this, ReminderService.class);
会在同一方法ReminderService
TodoTask.PARCELABLE_KEY收到意图
请记住，无法保证这将是服务的同一个实例。如果您正在运行的服务被系统杀死，则将启动它的新实例来处理意图。
还要记住Larry_Schiefer在答案中提到的所有睡眠和打盹模式。
