报警管理器执行方法

Question

这是我从google和youtube结合在一起的代码的一部分，用于执行＆＃34; turnOnLed＆＃34;当闹钟响起时。由于某种原因，它没有执行，我不知道如何使它工作。有人可以帮忙吗？我是谷歌，但没有成功。

谢谢。

 private void startAlarm(Calendar c)
    {
      AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    if (c.before(Calendar.getInstance()));
    {
    c.add(Calendar.DATE, 1);
    }

    Intent intent = new Intent(this, Control.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this,0,intent, 0);
    alarmManager.set(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(), pendingIntent);

    }

public class Control extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) 
    {
     turnOnLed(); //method to turn on
    }
}
