我想打开一个包含所有短信和彩信的数据库。我想这样做是因为我需要进行原始查询，所以我需要让它工作。我正在尝试这样做：

    try{
      SQLiteDatabase sqLiteDatabase = SQLiteDatabase.openDatabase("/data/data/com.android.providers/telephony/databases/mmssms.db", null, SQLiteDatabase.OPEN_READWRITE);
    }catch(Exception e){
       e.printStackTrace();
    }

我收到这样的错误：
