问题描述

我正在从的Andr​​oid HttpURLConnection的文档下面的测试Java脚本的:

I'm running the following test Java script from the Android HttpURLConnection docs:

URL url = new URL("http://www.android.com/");
HttpURLConnection urlConnection = (HttpURLConnection)
url.openConnection();
urlConnection.connect();

的Eclipse(在我的Mac)告诉我,当我有这个运行在Android模拟器是一个系统错误:

Eclipse (on my Mac) is telling me there's a system error when I run this in the Android Emulator:

01-13 13:44:32.767:WARN / System.err的(1382):java.net.SocketException异常:权限被拒绝

(顺便说一句,当我做等值的Objective-C /可可有一点问题都没有。)

(Incidentally when I do the equivalent in Objective-C/Cocoa there's no problem at all.)

这是什么问题?
