I am tring to make an android app to connect at an LDAP server. I am using UnboundId library so my app to be able to establish an LDAP connection. The problem is the resultCode 91-connection error and I don't know how to resolve it. The LDAP server is up and running because my desktop app can establish a connection. I will attach the code:
我正在尝试制作一个android应用程序，在LDAP服务器上进行连接。我使用UnboundId库，这样我的应用程序就能够建立一个LDAP连接。问题是结果码91-connection错误，我不知道如何解决它。LDAP服务器已经启动并运行，因为我的桌面应用程序可以建立连接。我将附上代码:
TextView tv = (TextView)findViewById(R.id.textView);
try {
LDAPConnection c = new LDAPConnection("192.168.106.131",389,"cn=admin,dc=test,dc=com","haha");
if(c.isConnected())
{
tv.setText("good");
}
else
{
tv.setText("bad");
}
} catch (LDAPException e) {
tv.setText("error");
e.printStackTrace();
}
And the log from LogCat:

The error message indicates that the device can't establish a connection to the specified IP address. 192.168.. is a private LAN network, so if you're using your carrier's mobile network then it wouldn't have access to it. If the device is on WiFi, then it's possible that you still might need to have some VPN tunnel.
错误消息指出该设备无法建立到指定IP地址的连接。192.168 . .是一个私有的局域网网络，所以如果你在使用你的运营商的移动网络，那么它就无法访问它。如果设备是在WiFi，那么你可能仍然需要一些VPN隧道。
If you know of a web server running on that same network, then you could use a web browser to test connectivity to that network. Alternately, you could try the LDAP client with a public directory server (for example, you could try directory.verisign.com on port 389 for unencrypted communication).
如果您知道在同一网络上运行的web服务器，那么您可以使用web浏览器来测试连接到该网络的连接。或者，您可以使用公共目录服务器尝试LDAP客户机(例如，您可以在端口389上尝试directory.verisign.com进行非加密通信)。
