java.lang.OutOfMemoryError - 非常大的 SOAP 响应

Question

我有一个 android 应用程序，它调用 web 服务并以 xml 格式获取新闻！

解析大量新闻时它给了我一个 outOfMemoryError ！

请问我该如何解决？！有什么帮助吗？！

这是我的 logcat 错误：

我从服务器获取数据的方法

if(categories.equals("") || categories.isEmpty() || categories == null)
            categories = "1;2;3;4;5;6;7;";
            getReportsObjZ.country = "0";
            getReportsObjZ.category = categories;
            getReportsObjZ.fdate = date_from;
            getReportsObjZ.tdate = date_to;

            try 
            {
                SharePoint_GetReportsByCatCntryResponse response = smartSearchSoap.SharePoint_GetReportsByCatCntry(getReportsObjZ);

                reportsXML = smartSearchSoap.getCountriesListFromService();
            }

            catch (Exception e) 
            {
                e.printStackTrace();
            }

            XMLParser parser = new XMLParser();

            Document doc = parser.getDomElement(reportsXML);

            NodeList nl = doc.getElementsByTagName(TAG_LIST);

            dbObject.open();


            dbObject.delete_ALL_ROWS();

            for (int i = 0; i < nl.getLength(); i++) 
            {
                Element e = (Element) nl.item(i);

                String just_date_without_time = getJustDATE(parser.getValue(e,TAG_CREATED_P));
                String just_time_without_date = getJustTIME(parser.getValue(e,TAG_CREATED_P));
                String numberical_category = "";



                dbObject.createEntry(parser.getValue(e, TAG_TITLE),
                        parser.getValue(e, TAG_COUNTRY_ID),
                        parser.getValue(e, TAG_DESCRIPTION),
                        parser.getValue(e, TAG_IDP),
                        removeSpecialChars(parser.getValue(e, TAG_CATEGORYP)),
                        just_date_without_time, just_time_without_date,
                        parser.getValue(e, TAG_CREATED_BY),
                        parser.getValue(e, TAG_TAGS),
                        parser.getValue(e, TAG_READ_BY),
                        removeSpecialChars(parser.getValue(e, TAG_CITY)),
                        (parser.getValue(e, TAG_DIR)),
                        removeSpecialChars(parser.getValue(e, TAG_LINK)),numberical_category);
            }

            dbObject.close();

android有堆限制，从你的文件中分块读取XML数据并方便解析

或

尝试将android:largeHeap="true" 放在清单文件的应用程序标记中。
