在使用Smack时尝试连接到Openfire（我已安装在计算机上）时遇到了一些麻烦。

I'm having a little bit of trouble trying to connect to Openfire (which I've installed on my computer) while using Smack.

ConnectionConfiguration config = new ConnectionConfiguration("shin-pc" ,5222); config.setCompressionEnabled(true); config.setSASLAuthenticationEnabled(true); XMPPConnection connection = new XMPPConnection(config); connection.connect(); connection.login("test", "test");

当我尝试调试或运行时，中出现某种错误connect（） line。

When I try debugging or running, there's an error of some sort in the connect() line.

连接到localhost的XMPPError：5222：remote-server-error（502）连接到localhost的XMPPError ：5222。 - 由：java.SocketException：权限被拒绝。

我尝试将主机名切换为localhost，它没有'或者工作。

I've tried switching the host name to "localhost", and it didn't work either.

我没有这个XMPP业务的经验所以我想这是一个常见的新手问题或类似的东西......

I have no experience in this XMPP business so I guess it's a common newbie problem or something of the sort...

可能是什么问题？我如何解决这个问题，以便连接成功？

What might be the problem? How can I fix this so the connection will be successful?

推荐答案

我刚刚创建了一个我需要XMPP的新项目，遇到了同样的问题。但是，我意识到这只是因为我忘了在我的清单中添加互联网权限：

I just created a new project in which I need XMPP, and ran into the same problem. However, I realized that it was simply because I had forgotten to add the internet permission in my manifest:

<uses-permission android:name="android.permission.INTERNET"/>

确保你没有犯同样的错误。

Make sure that you haven't done the same mistake.
