Android Simple asmack gmail 聊天

Question

大家好，标题说明了一切。 我正在使用 asmack-android-8-4.0.6.jar。

代码是：

 //1. connect to server
 ConnectionConfiguration ConnectionConfiguration = new ConnectionConfiguration("gmail.com");

ConnectionConfiguration.setSecurityMode(SecurityMode.required);                
ConnectionConfiguration.setDebuggerEnabled(true);
XMPPConnection connection = new XMPPTCPConnection(ConnectionConfiguration);     

try {   connection.connect();  report+="Connected to server\n"; }
catch (ConnectionException e){ report+=e.toString()+" - (1)\n"; }
catch (SmackException e)     { report+=e.toString()+" - (2)\n"; }
catch (IOException e)        { report+=e.toString()+" - (3)\n"; }
catch (XMPPException e)      { report+=e.toString()+" - (4)\n"; }
tv.setText(report);

 //2. login
 try{   connection.login("myGmailId","MyGmailPwd"); report+="Logged in server\n";}
 catch (SaslException e)  { report+=e.toString()+"\n"; }
 catch (XMPPException e)  { report+=e.toString()+"\n"; }
 catch (SmackException e) { report+=e.toString()+"\n"; }
 catch (IOException e)   { report+=e.toString()+"\n"; }

我无法进入第二部分，因为我已经从第一部分收到以下错误：

org.jivesoftware.smack.SmackException$连接异常（一）

我也配置了proguard

-dontnote org.xbill.DNS.spi.DNSJavaNameServiceDescriptor
-dontwarn org.xbill.DNS.spi.DNSJavaNameServiceDescriptor

由于我被困一个月以来，请提供任何帮助。 谢谢 妙招

可能有点晚了：

首先，dnsjava lib是否正确添加到项目中？ some people forget about this README.

对于 ConnectionException，也许这样的事情会有所帮助：

try
{
 connection.connect();
}
 catch (SmackException e)
{
  Log.i("SmackException ", "ConnectionException: " + e.getMessage());

  List<HostAddress> hostAddresses = ((SmackException.ConnectionException) e).getFailedAddresses();

  if (!hostAddresses.isEmpty())
     {
        Log.i("SmackException: HostAddress: ", hostAddresses.get(0).toString());
        Log.i("SmackException: HostAddress: ", hostAddresses.get(0).getException().toString());
     }

}
