無法將XMPP服務器與Android中的ASmack連接起來

Question

我有一個完全適用於Java的Chat Client。現在我期待在我的android設備上實現相同的功能。我開始在項目中導入ASmack庫，並在每個階段檢查以避免錯誤。儘管如此，我還是陷入了第一步。我的活動無法在ASmack Jar中找到該課程，因此我認爲我無法繼續。

我的簡單代碼：

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的日誌：

附加信息：我已經asmack-Android的7.jar庫中導入。我的AVD正在運行2.3.3 Android。

我認爲由於這個，我得到了致命的例外。 我在這裏錯過了什麼？您的幫助將不勝感激。謝謝。

這是我的代碼，它的工作對我罰款，我希望它有幫助你。 謝謝

試試這個

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(); 
       }

我找到了解決這個問題。這是由於我對API進行了更新。我從我的項目屬性中刪除了導入的ASmack庫。 Lib文件夾也丟失了。因此，我製作了一個文件夾（「libs」），他在項目中粘貼了ASmack jar。通過清理一次該項目，錯誤得到修復。 謝謝。 Reference
