我曾经在其他项目中使用以下代码段设置警报作为重复和非重复，但现在让我抓狂的是，我犯了一个愚蠢的错误，因为警报与我当前的实现无关：\ ：

private fun setAlarm(obj: MyObject, time: Long) {
    val intent = Intent(applicationContext, MyAlarmIntentService::class.java)
    intent.putExtra(C.KEY_ME, obj)

    val pendingIntent = PendingIntent.getService(applicationContext, 43, intent, 
                                          PendingIntent.FLAG_UPDATE_CURRENT)

    val context = this@MyActivity
    val cal = Calendar.getInstance()
    cal.timeInMillis = time * 1000   // time is in seconds
    Log.d("setAlarm", "setting time -> $time for obj = $obj")
    Log.d("setAlarm", "Set calendar: " + cal.toString())

    val alarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager

    @RequiresApi(Build.VERSION_CODES.LOLLIPOP)  // Overriding doze-mode
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        val alarmClockInfo =
                AlarmManager.AlarmClockInfo(cal.timeInMillis, null)
        alarmManager.setAlarmClock(alarmClockInfo, pendingIntent)
    }

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) // Overriding doze-mode
        // Not-working in Nexus 6 - API 25 (7.1.1), but works in API 23 (6.0.1, tested in multiple devices)
        alarmManager.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, 
                    cal.timeInMillis, pendingIntent) 
    else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) // Works
        alarmManager.setExact(AlarmManager.RTC_WAKEUP, cal.timeInMillis, pendingIntent)
    else // works
        alarmManager.set(AlarmManager.RTC_WAKEUP, cal.timeInMillis, pendingIntent)
}

IntentService 类如下：

class MyAlarmIntentService : IntentService("Notification") {

  override fun onHandleIntent(intent: Intent?) {
    val obj = intent?.getParcelableExtra<MyObj>(C.KEY_ME) ?: return
    Lg.d(TAG, "My alarm fired for - \n" + obj.toString())
  }

  companion object {
    private val TAG = ContestAlarmIntentService::class.java.simpleName
  }

}

该服务在清单中声明为：

<service android:name=".services.MyAlarmIntentService" />

以下是提到的 log insidesetAlarm()方法的示例：

E/setAlarm: setting time -> 1514993850 for obj = MyObj{...}
E/setAlarm: Set calendar: java.util.GregorianCalendar[time=1514993850000,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=libcore.util.ZoneInfo[id="Asia/Dhaka",mRawOffset=21600000,mEarliestRawOffset=23400000,mUseDst=false,mDstSavings=0,transitions=7],firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2018,MONTH=0,WEEK_OF_YEAR=1,WEEK_OF_MONTH=1,DAY_OF_MONTH=3,DAY_OF_YEAR=3,DAY_OF_WEEK=4,DAY_OF_WEEK_IN_MONTH=1,AM_PM=1,HOUR=9,HOUR_OF_DAY=21,MINUTE=37,SECOND=30,MILLISECOND=0,ZONE_OFFSET=21600000,DST_OFFSET=0]

这对我来说曾经是一个直截了当的代码，但是在这 3 天的测试会话中，我可能会缺少哪个基础知识？

抱歉，由于我正忙于另一项任务，所以我没有查看您的所有代码，所以这是我与 Broadcast 一起使用的代码

Intent intent = new Intent(context, AlarmReceiver.class);
    intent.setAction(UtilAlarmConstants.ALARM_ACTION);
pIBroadCast = PendingIntent.getBroadcast(context, ALARM_PI_REQ_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    alarmManager = (AlarmManager) context.getApplicationContext().getSystemService(Context.ALARM_SERVICE);

    if (alarmManager != null) {

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
          alarmManager.setExactAndAllowWhileIdle(ALARM_TYPE, calendar.getTimeInMillis(),pendingIntent);

        else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            AlarmManager.AlarmClockInfo alarmClockInfo
                    = new AlarmManager.AlarmClockInfo(System.currentTimeMillis() + fireAT, null);
            alarmManager.setAlarmClock(alarmClockInfo, pIBroadCast);
        }
        //setExact for 19
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            alarmManager.setExact(AlarmManager.RTC_WAKEUP, fireAT, pIBroadCast);
        } else {
            alarmManager.set(AlarmManager.RTC_WAKEUP, fireAT, pIBroadCast);
        }
    }

和广播

    if (intent != null && intent.getAction() != null) {

        if (intent.getAction().equalsIgnoreCase(UtilAlarmConstants.ALARM_ACTION)) {

            setUpNotification(context, intent);}

很抱歉没有给出与服务相关的答案，因为它们都是一样古怪的 dacky :)
