安卓服務意外停止

Question

嗨，目前我正在執行安卓通知功能使用報警管理器和服務，但是當我在Android設備上啓動應用程序時，它顯示應用程序意外停止當我從應用程序中刪除應用程序按住主頁按鈕即可顯示「最近的應用」列表。當應用程序未從「最近的應用程序」列表中刪除時，它工作正常。

任何人都可以建議我在這裏做錯了什麼？ 感謝您的回覆。

我有一個活動讓用戶決定他們是否想要收到通知。然後該值傳遞給Trade.java

Trade.java

//the part where alarm manager is trigger 
if(spApp_checkbox.getBoolean("checkbox", false) == true){ 
      if(spApp_checkbox.getInt("time", 0) <= 10){ 
       setTime = 60*1000; 
      } 
      else{ 
       setTime = spApp_checkbox.getInt("time", 0)*1000; 
      } 
      Calendar calender = Calendar.getInstance(); 
       AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
       intent.setClass(this, MyService.class); 

       PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 
       alarm.setRepeating(AlarmManager.RTC_WAKEUP, calender.getTimeInMillis(), setTime, pendingIntent); 
       this.startService(intent); 
     } 
     else{ 
      AlarmManager alarmManagerstop = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
       Intent intentstop = new Intent(this, MyService.class); 
       PendingIntent senderstop = PendingIntent.getService(getApplicationContext(), 0, intentstop, 0); 
      // Cancel alarms 
       try { 
        alarmManagerstop.cancel(senderstop); 
       } catch (Exception e) { 
        Log.e("TAG", "AlarmManager update was not canceled. " + e.toString()); 
       } 
       this.stopService(intentstop); 
     } 

MyService.java

public class MyService extends Service { 

    private static String SOAP_ACTION1 = "http://pagecode/getTradeControlList_ByParameters"; 
    private static String NAMESPACE = "http://pagecode";

    @Override

    @Override

      Vector<SoapObject> obj1_new = showTrade(callby, tradeCrtl, days); 
     int[] id_new = new int[obj1_new.size()]; 
     if(obj1_new != null){ 
      for (int i = 0; i < obj1_new.size(); i++) { 
        id_new[i] = Integer.valueOf(words[0]); 

        if(!hm.containsKey(id_new[i])){ 
         NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
         NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this); 

         PendingIntent in = PendingIntent.getActivity(getApplicationContext(), 0, intent_tr, 0); 
         System.out.println("list changes"); 
         mBuilder.setContentTitle("Application") 
         .setContentText("New trade available") 
         .setProgress(0, 0, false) 
         .setSmallIcon(R.drawable.ic_logo) 
         .setDeleteIntent(in) 
         .setAutoCancel(true); 

        mBuilder.setContentIntent(in); 
        mNotificationManager.notify(0, mBuilder.build()); 
        hm = new HashMap(); 
        }   
      } 

      for (int j = 0; j < obj1_new.size(); j++) { 
       hm.put(id_new[j], id_new[j]); 

      } 
     } 
      return super.onStartCommand(intent, flags, startId); 
    } 
}
