AlarmManager無法啓動服務意圖

任何人都可以告訴我爲以下代碼做出什麼愚蠢的錯誤，並得到錯誤。AlarmManager無法啓動服務意圖

我已經嘗試了類似的stackoverflow帖子和示例。

錯誤：9月6日至24日：06：36.074：W/ActivityManager（61）：無法啓動服務意圖{FLG =爲0x4 CMP = com.example.myapp/.Updater（具有額外）}：不發現

package com.example.myapp; 

import android.app.AlarmManager; 
import android.app.PendingIntent; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.content.SharedPreferences; 
import android.util.Log; 

public class Booter extends BroadcastReceiver { 

     public void onReceive(Context context, Intent intent) { 
     String action = intent.getAction(); 

     if (action.equals(Intent.ACTION_BOOT_COMPLETED)) { 
      Log.e("boot-status","BOOT_COMPLETED=========================="); 
     // SharedPreferences prefs = context.getSharedPreferences("$MYPACKAGE_preferences",0); 
     // if (prefs.getBoolean("startatboot",false)) { 
     if(true){ 
     Intent updateIntent = new Intent(); 
     updateIntent.setClass(context, Updater.class); 

     PendingIntent pendingIntent = PendingIntent.getService(context, 0, updateIntent, 0); 
     AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
     alarmManager.set(AlarmManager.RTC_WAKEUP, java.lang.System.currentTimeMillis()+60000, pendingIntent); 
      } 
     } 
     }
