无法将XMPP服务器与Android中的ASmack连接起来

Question

我有一个完全适用于Java的Chat Client。现在我期待在我的android设备上实现相同的功能。我开始在项目中导入ASmack库，并在每个阶段检查以避免错误。尽管如此，我还是陷入了第一步。我的活动无法在ASmack Jar中找到该课程，因此我认为我无法继续。

我的简单代码：

package com.test.mypro; 

import org.jivesoftware.smack.ConnectionConfiguration; 
import org.jivesoftware.smack.XMPPConnection; 
import org.jivesoftware.smack.XMPPException; 

import android.app.Activity; 
import android.os.Bundle; 
import android.util.Log; 
import android.widget.TextView; 

    public class TestProjectActivity extends Activity { 
     private static final String LOG_TAG = "TESTER"; 
     /** Called when the activity is first created. */ 
     TextView tvHello; 
     XMPPConnection connection; 
     ConnectionConfiguration config; 

     @Override 
     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.main); 
      tvHello = (TextView) findViewById(R.id.tvHello); 
      Log.i(LOG_TAG, "I'm here"); 
      config = new ConnectionConfiguration("prc.p1.im", 5222, "prc.p1.im"); 
      connection = new XMPPConnection(config); 
      try { 
       connection.connect(); 
       // tvHello.setText("Connected to XMPP server"); 
       Log.i(LOG_TAG, "Successfully Connected"); 
      } catch (XMPPException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
       Log.e(LOG_TAG, "Not Connected"); 
      } 
     } 
    } 

logcat的日志：

附加信息：我已经asmack-Android的7.jar库中导入。我的AVD正在运行2.3.3 Android。

我认为由于这个，我得到了致命的例外。 我在这里错过了什么？您的帮助将不胜感激。谢谢。

试试这个

private final static String server_host = "talk.google.com"; 
private final static int SERVER_PORT = 5222; 
private final static String SERVICE_NAME = "gmail.com"; 

ConnectionConfiguration config = new ConnectionConfiguration(server_host, SERVER_PORT , SERVICE_NAME); 
     XMPPConnection m_connection = new XMPPConnection(config); 
       try { 
        SASLAuthentication.supportSASLMechanism("PLAIN"); 
        config.setSASLAuthenticationEnabled(true);  
        m_connection.connect(); 
        Roster.setDefaultSubscriptionMode(Roster.SubscriptionMode.manual); 
       } catch (XMPPException e) { 
        e.printStackTrace(); 
       }

我找到了解决这个问题。这是由于我对API进行了更新。我从我的项目属性中删除了导入的ASmack库。 Lib文件夹也丢失了。因此，我制作了一个文件夹（“libs”），他在项目中粘贴了ASmack jar。通过清理一次该项目，错误得到修复。 谢谢。 Reference
