Why can't I connect to the openfire server?
提问by Bar
I'm having a little bit of trouble trying to connect to Openfire (which I've installed on my computer) while using Smack.
在使用 Smack 时，我在尝试连接到 Openfire（我已安装在我的计算机上）时遇到了一些麻烦。
ConnectionConfiguration config = new ConnectionConfiguration("shin-pc" ,5222);
config.setCompressionEnabled(true);
config.setSASLAuthenticationEnabled(true);
XMPPConnection connection = new XMPPConnection(config);
connection.connect();
connection.login("test", "test");
When I try debugging or running, there's an error of some sort in the connect()line.
当我尝试调试或运行时，行中出现某种错误connect()。
XMPPError connecting to localhost:5222.: remote-server-error(502) XMPPError connecting to localhost:5222. -- caused by: java.net.SocketException: Permission denied.
XMPPError 连接到 localhost:5222.: remote-server-error(502) XMPPError 连接到 localhost:5222。-- 引起：java.net.SocketException：权限被拒绝。
I've tried switching the host name to "localhost", and it didn't work either.
我试过将主机名切换为“localhost”，但也没有用。
I have no experience in this XMPP business so I guess it's a common newbie problem or something of the sort...
我在这个 XMPP 业务方面没有经验，所以我猜这是一个常见的新手问题或类似的问题......
What might be the problem? How can I fix this so the connection will be successful?
可能是什么问题？如何解决此问题以便连接成功？

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:
我刚刚创建了一个需要 XMPP 的新项目，但遇到了同样的问题。但是，我意识到这仅仅是因为我忘记在清单中添加互联网权限：
<uses-permission android:name="android.permission.INTERNET"/>
Make sure that you haven't done the same mistake.
确保你没有犯过同样的错误。

回答by Rahul Arora
Use host as localhost if you are using a device. If you are using an emulator, use ip address (192.168.1.2 or whatever) in the configuration step (line 1 of the given code)
如果您使用的是设备，请使用主机作为 localhost。如果您使用的是模拟器，请在配置步骤（给定代码的第 1 行）中使用 ip 地址（192.168.1.2 或其他）
