FileNotFoundException异常的HttpURLConnection的在冰淇淋三明治

问题描述

我有一个Android应用程序的正常工作与Android 2.x和3.x，但它在Android 4.x版上运行时出现故障。

I have an Android app that works fine with Android 2.x and 3.x, but it fails when run on Android 4.x.

现在的问题是在本节的code：

The problem is in this section of code:

URL url = new URL("http://blahblah.blah/somedata.xml");
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
urlConnection.connect();

InputStream inputStream = urlConnection.getInputStream();

当应用程序在Android 4.x的运行，在 FileNotFoundException异常的的getInputStream（）通话效果。当相同的二进制文件在早期版本的Andr​​oid上运行，它成功。该网址也很好地工作在Web浏览器，并与卷曲。

When the application is running on Android 4.x, the getInputStream() call results in a FileNotFoundException. When the same binary is running on earlier versions of Android, it succeeds. The URLs also work fine in web browsers and with curl.

显然，一些关于的HttpURLConnection 在ICS已经改变。没有任何人有任何想法发生了什么变化，和/或如何修复可能是什么？

Apparently something about HttpURLConnection has changed in ICS. Does anybody have any idea what has changed, and/or what the fix might be?
