标签： android json ksoap2

我使用kso​​ap2从服务器获取数据（我的数据约为6MB） 我的代码：

                   SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);
            // envelope.dotNet=true;
            envelope.setOutputSoapObject(request);
            HttpTransportSE androidhttpTranport = new HttpTransportSE(URL,
                    ContantSystem.TimeOut);
            androidhttpTranport.call(SOAP_ACTIONS, envelope);

            Object responseBody = null;
            try {
                responseBody = envelope.getResponse();
            } catch (SoapFault e2) {
                // TODO Auto-generated catch block

            }

当我同步数据时，我的应用显示异常：

Affter我设置android:largeHeap="true"如果我在android 4.0.3上运行我的应用程序，我的应用程序运行正常。但我在Android 2.3上运行我的应用程序，我的应用程序死了并显示异常：java.lang.OutOfMemoryError 为什么？如何解开这个问题？感谢。

这是什么类型的数据？

也许您或者图书馆正在一个块中读取数据，这可能不是一个好主意，尝试在小缓冲区中读取它，然后将其存储在文件缓存中。

您可以使用ActivityManager.getMemoryClass（）和ActivityManager.getLargeMemoryClass（）来确保已分配更多内存。试一试。
