内存不足错误在 KXmlParser.

Question

>我从服务器获取数据如下：

HttpTransportSE androidhttpTranport = new HttpTransportSE(URL, ContantSystem.TimeOut);
androidhttpTranport.call(SOAP_ACTIONS, envelope);
Object responseBody = responseBody = envelope.getResponse();

我的应用程序显示了一个示例：

我的数据约为2.4MB。（5.000.000 个字符）。我的设备内存有限制吗？为什么？

Answer 1

内存限制是针对整个应用的，而不仅仅是针对 http。 因此，您在应用程序的其他地方使用了大量内存，或者您的手机整体内存不足。 不过很可能是您的应用程序。 在您的应用程序上运行 hprof，看看您是否泄漏了引用。 信不信由你，大型Java程序中的内存管理需要与C++一样多的努力，而Android的框架很容易泄漏许多传递给它的对象，就像活动一样。
