我有一个AlarmManager的问题,我设置了调度重复警报的代码,在我运行应用程序后,警报运行正常.即使我单击"主页"按钮(并且应用程序暂停),警报仍会按其间隔运行.

问题是如果我打开任务管理器并强制关闭应用程序,则警报将停止运行.

这是正常的行为,有没有办法避免这种情况并在关闭应用程序后保持警报运行？

代码如下 - 该方法由ApplicationContext类onCreate()调用.

 private void scheduleAlarm() {
  if (alarmScheduled == true) { return; } // we only need to schedule once.

  int alarmInterval = Def.pref(getApplicationContext()).getInt("alarmInterval", 30);

  final Intent intent = new Intent(getApplicationContext(), CollectorAlarmReceiver.class);
  final PendingIntent pending = PendingIntent.getBroadcast(getApplicationContext(), 0, intent, 0);

  AlarmManager alarmMgr = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);

  alarmMgr.cancel(pending); // cancel others.

  alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+1000,
    alarmInterval*1000, pending);

  Def.log(TAG,"scheduleAlarm(): alarm scheduled, interval: "+alarmInterval+" seconds");
  alarmScheduled = true;
 }

接收者代码:

public void onReceive(Context context, Intent intent) {
    Log.i(TAG, "CollectorAlarmReceiver invoked, starting CollectorService …
