在特定时间开始和停止服务

我的应用正在进行人类活动识别并通知用户它们是否不够活跃。我正在阅读始终运行的前台服务中的加速计数据。此刻，当用户正在睡觉时（例如，用户将睡眠时间间隔设置为晚上8点至早上8点），我试图启动和停止该服务，以便在指定的时间之后停止并重新开始服务。目前，下面的代码不起作用，我不知道为什么。有什么建议吗？在特定时间开始和停止服务

注：我知道，我将使代码重用莫名其妙的日历实例，这只是用于调试的目的，得到它的第一个工作日。

Date startSleepingHours = mUser.getStartSleepingHours(); 
    Date stopSleepingHours = mUser.getStopSleepingHours(); 
    //Create alarm manager 
    AlarmManager alarmMgr0 = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 

    Calendar cur_cal = new GregorianCalendar(); 
    cur_cal.setTimeInMillis(System.currentTimeMillis());//set the current time and date for this calendar 

    Calendar cal = new GregorianCalendar(); 
    cal.add(Calendar.DAY_OF_YEAR, cur_cal.get(Calendar.DAY_OF_YEAR)); 
    cal.set(Calendar.HOUR_OF_DAY, startSleepingHours.getHours()); 
    cal.set(Calendar.MINUTE, startSleepingHours.getMinutes()); 
    cal.set(Calendar.SECOND, cur_cal.get(Calendar.SECOND)); 
    cal.set(Calendar.MILLISECOND, cur_cal.get(Calendar.MILLISECOND)); 
    cal.set(Calendar.DATE, cur_cal.get(Calendar.DATE)); 
    cal.set(Calendar.MONTH, cur_cal.get(Calendar.MONTH)); 

    Intent startServiceIntent = new Intent(ActiveMinutesActivity.this, IntentBroadcastedReceiver.class); 
    Intent stopServiceIntent = new Intent(ActiveMinutesActivity.this, IntentBroadcastedReceiver.class); 
    stopServiceIntent.putExtra("command", "STOP_SERVICE"); 

    PendingIntent stopServicePIntent = PendingIntent.getService(ActiveMinutesActivity.this, 0, stopServiceIntent, 0); 

    PendingIntent startServicePIntent = PendingIntent.getService(ActiveMinutesActivity.this, 1, startServiceIntent, 0); 

    AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
    alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 60 * 1000, stopServicePIntent); 


    Calendar cal2 = new GregorianCalendar(); 
    cal2.add(Calendar.DAY_OF_YEAR, cur_cal.get(Calendar.DAY_OF_YEAR)); 
    cal2.set(Calendar.HOUR_OF_DAY, stopSleepingHours.getHours()); 
    cal2.set(Calendar.MINUTE, stopSleepingHours.getMinutes()); 
    cal2.set(Calendar.SECOND, cur_cal.get(Calendar.SECOND)); 
    cal2.set(Calendar.MILLISECOND, cur_cal.get(Calendar.MILLISECOND)); 
    cal2.set(Calendar.DATE, cur_cal.get(Calendar.DATE)); 
    cal2.set(Calendar.MONTH, cur_cal.get(Calendar.MONTH)); 


    alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal2.getTimeInMillis(), 60 * 1000, startServicePIntent);

我的接收器类：

public class IntentBroadcastedReceiver extends BroadcastReceiver { 
public IntentBroadcastedReceiver() { 
} 

@Override 
public void onReceive(Context context, Intent intent) { 
    if(intent.getExtras() != null){ 
     if(intent.getExtras().get("command").equals("STOP_SERVICE")){ 
      context.stopService(new Intent(context, ActiveMinutesService.class)); 
     }else { 
      context.startService(new Intent(context, ActiveMinutesService.class)); 
     } 
    } 

} 
}

是否定义为IntentBroadcastedReceiver在AndroidManifest.xml接收器？即：

<receiver android:name=".IntentBroadcastedReceiver "></receiver>

感谢您的建议。是的，我已经在清单中定义了接收器。 –
