我虽然在我的代码的最后一次更改之后,我的“定时器接收器”工作,但它不是......

我可以启动管理器并调用 Receiver,然后,几个小时后,AlarmManager 停止工作。

我的应用程序中有一个代码来检查 AlarmManager 是否运行,它说它确实运行,但不会调用 Receiver。

这是我的代码:

  private AlarmManager alarmMgr;
  private PendingIntent checkPendingIntent;

  public void initTimer()
  {
    this.alarmMgr = (AlarmManager)this.main.getSystemService(Context.ALARM_SERVICE);

    this.alarmActive = (PendingIntent.getBroadcast(this.main, 0,
        new Intent(this.main, AlarmReceiver.class), PendingIntent.FLAG_NO_CREATE) != null);
    this.checkPendingIntent = PendingIntent.getBroadcast(this.main, 0,
                  new Intent(this.main, AlarmReceiver.class), PendingIntent.FLAG_UPDATE_CURRENT);
  }

  public void startTimer(String frequency)
  {
    Calendar now = Calendar.getInstance();
    Calendar calendar = Calendar.getInstance();
    long millis = 0;

    if(frequency.compareTo("1HOUR") == 0)
      millis = AlarmManager.INTERVAL_HOUR;
    if(frequency.compareTo("12HOUR") == 0)
      millis = AlarmManager.INTERVAL_HALF_DAY;
    if(frequency.compareTo("1DAY") == 0)
      millis = AlarmManager.INTERVAL_DAY;
    if(frequency.compareTo("1WEEK") == 0)
      millis = 7 * AlarmManager.INTERVAL_DAY;

    calendar.setTimeInMillis(System.currentTimeMillis());
    if(calendar.before(now))
      calendar.add(Calendar.DATE, 1);

    if(!this.timerSet)
      Logger.debug("Starting update checker (" + frequency + ")");
    else
      Logger.debug("Restarting update checker (" + frequency + ")");
    this.timerSet = true;
    this.alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
        millis, this.checkPendingIntent);
  }

好吧,this.alarmActive 是真的,所以我希望它可以工作,当然不会再次调用 startTimer 方法。但是我可以在我的手机和服务器上的日志中看到(接收器只是发送一个 HTTP 请求),接收器不会被调用......

有人可以说我,我做错了什么吗?

非常感谢
