我使用ksoap2从服务器获取数据（我的数据大约为6MB） 我的代码：

当我同步数据时，我的应用程序显示异常：

在我设置android:largeHeap=“true”后，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。但我在安卓2.3上运行我的应用程序，我的应用程序死机并显示异常：

java.lang.OutOfMemoryError

---

为什么？如何解开这个问题？谢谢。

这是什么样的数据

---

可能您或库正在读取单个块中的数据，这可能不是一个好主意，请尝试在小缓冲区中读取数据，然后将其存储在文件缓存中。

您可以使用ActivityManager.getMemoryClass（）和ActivityManager.getLargeMemoryClass（）确保分配了更多内存。试试看。

如果没有代码，我们无法知道为什么会发生这种情况。但总的来说，Android中的内存管理是一个真正的难题。。。看，我不能用c
