如何处理android中的web服务的大响应
问题描述：
我从webservice获得大的价值。我的回应即将到来，就像XML实体字符引用一样。我用strigescapeutils代替了字符。我将我的回复存储在一个字符串中。我收到内存不足的错误。我正在使用SAX解析器解析响应。我解析了这个值并将其存储在一个beans的数组列表中。在arraylist值添加它在textview。如何处理android中的web服务的大响应
我在执行此操作时遇到此错误：内存不足错误。我不知道如何在流中做。任何人都可以告诉我如何做到这一点？任何人都可以举个例子吗？是否有可能在bean和字符串的数组列表中添加大的值？
这是使用字符串解析器我的阅读解析值：
xr.parse(new InputSource(new StringReader(webservicevalue)));
我收到此错误：

答
OK，你是从Web服务接收一些XML，并且您解析这带SAX的XML。 SAX是一个流式解析器，它只读取XML文档的块，因此可以最小化所需的内存。所以你的程序的这部分按预期工作。
然后您将数据存储在ArrayList这意味着在内存中。你没有说你分析了多少条目，但我认为这是问题所在。您应该将条目存储在数据库中。您应该使用ContentProvider。你可以找到一个很好的教程来保存和显示数据here - 官方记事本练习1.
