收不到ACTION_TIME_TICK的广播

已解决……
问题不在于ACTION_TIME_TICK，而是我中途调用的方法会在特定情况下stopself
我本以为在service中加的那个notification会随着stopself消失，结果它没消失……于是我以为是广播出了问题……
以下是原题……

我看google是这么说的

Broadcast Action: The current time has changed. Sent every minute. You
cannot receive this through components declared in manifests, only by
explicitly registering for it with Context.registerReceiver().

于是我的代码：

public class AlarmService extends Service {

......

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
    
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
        builder.setSmallIcon(R.drawable.alarm_notify);
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.notify(0, builder.build());

//        alarm = getNextAlarm();  update: 这行居然是元凶！我稍微看看这个方法再更新一下题目。。。

        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(Intent.ACTION_TIME_TICK);
        timeTickReceiver = new TimeTickReceiver();
        registerReceiver(timeTickReceiver, intentFilter);

        return START_NOT_STICKY;
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        unregisterReceiver(timeTickReceiver);
    }

    class TimeTickReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            Toast.makeText(context, "received", Toast.LENGTH_SHORT).show();

        }
    }

}

debug能走到registerReceiver(timeTickReceiver, intentFilter);这一行，但后面的onReceive似乎永远都达不到，哪有问题呢。。。
