IllegalStateException

-1

我有一个预算的应用程序，虽然即时通讯试图从我的SQLite数据库获取infromation我不断得到IllegalStateExpeaction错误，我无法找出原因。这里是我的代码的那个错误发生IllegalStateException

public List<String> getMemo(List<String> expeances) { 
      // TODO Auto-generated method stub 
      List<String> Memos = new ArrayList<String>(); 
      for(String exp: expeances) 
      { 
       Cursor i = ourDatabase.query(DATABASE_TABLE4, new String[]{KEY_MEMO},KEY_DATE+" = '"+exp+"'", null, null, null, null,null); 

       if(i.getCount()>0) 
       { 
        if(i.moveToFirst()) 
        { 
         do 
         { 
          Memos.add(i.getString(1)); 
         } 
         while (i.moveToNext()); 
        } 
       } 
      } 

      if (Memos.size()>0) 
      { 
       return Memos; 
      } 
      else 
      { 
       return null; 
      } 
     }

这里行Memos.add(i.getString(1));是我的logcat
