Jsoup在安卓上Connection.get抛出NullPointerException异常（）模拟器

Question

我使用Jsoup为我的Android应用程序之一，我有一个比较简单的一段代码，不断抛出的NullPointerException当我打电话connection.get（）。

这用来工作一两个月回来，但安装最新的SDK后，不再在模拟器中工作。它在我的物理设备上工作正常，但我不知道这是否只是一个模拟错误或可能影响其他手机。

这是我的代码：

String URL = "http://finance.google.com/finance/feeds/default/portfolios?returns=true" 
String _AUTHPARAMS = "GoogleLogin auth=" 
String AuthToken = "random string of characters" 

Connection c = Jsoup.connect(URL); 
c.header("Authorization", _AUTHPARAMS + AuthToken); 
c.userAgent("foo"); 
c.timeout(10000); 
c.ignoreContentType(true); 
Document doc = c.get(); 

我赶上最后一行一个NullPointerException（c.get（））

如果我叫exception.getMessage（），它只是说“空”。我不确定除了android或jsoup中的错误之外，还有什么可能导致这种情况？

我使用Jsoup 1.6.1

从您的堆栈跟踪我猜你在Android 2.1（或其他的“旧”版本）遇到此bug (15554) - 你应该能够下载使用Apache HTTP客户端的文件 - 这更好的工作了很多较旧的Android实现（因为HttpURLConnection是/是狗屎）。
