无法在Android studio和ejabberd 16.04 windows localhost上使用smack 4.1.6设置XMPP

Question

我是XMPP的新手，我试图在android studio中设置从我的Android设备到ejabberd-16.04服务器的XMPP连接。但是在用户名和密码登录时遇到问题。

我已从https://community.igniterealtime.org/thread/57209

导入代码

我收到此错误 java.security.cert.CertPathValidatorException：找不到证书路径的信任锚。

我的XMPP连接详情是：

private static final String DOMAIN = "localhost";
private static final String HOST = "192.168.1.xxx";
private static final int PORT = 5222;
private String userName ="admin@localhost";
private String passWord = "admin";

当我尝试从移动浏览器进行连接时，相同的凭据正在运行。

XMPP连接代码：

   XMPPTCPConnectionConfiguration.Builder configBuilder =      XMPPTCPConnectionConfiguration.builder();
  configBuilder.setUsernameAndPassword(userName, passWord);
  configBuilder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
  configBuilder.setResource("Android");
  configBuilder.setServiceName(DOMAIN);
  configBuilder.setHost(HOST);
  configBuilder.setPort(PORT);
   //configBuilder.setDebuggerEnabled(true);
   connection = new XMPPTCPConnection(configBuilder.build());
   connection.addConnectionListener(connectionListener);
