smak 4.1.0 beta3 xmppconnection错误

Question

i'v测试eclipse与Smack 4.1.0 Beta3和本地主机openfire之间的连接，但出现了一些错误。

XMPPTCPConnectionConfiguration conf =XMPPTCPConnectionConfiguration.builder() 
      .setHost("127.0.0.1") 
      .setPort(5222) 
      .setCompressionEnabled(false) 
      .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled) 
      .build(); 
    XMPPTCPConnection connection = new XMPPTCPConnection(conf); 

    try { 
     connection.connect(); 
     connection.login("admin","admin"); 
    } catch (SmackException | IOException | XMPPException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 

当我在Android应用程序“模拟器” 运行

我得到消息Unfortunately,test_connection has stopped. 和logcat的显示

FATAL EXCEPTION: main 
Process:com.example.test_connection, PID: 1956 
java.lang.NoClassDefFoundError: org.jxmpp.util.XmppStringUtils

你没写你使用的是什么版本的Openfire的。如果它3.9.3下面的例子应该是有帮助的。祝你好运！

的Smack版本：咂嘴-4.2.0-α1 - 快照 的Openfire版本： 3.9.3

的Smack库：芯，IM，java7，SASL提供的，TCP

带附加库： jxmpp-UTIL缓存-0.4.1.jar， jxmpp核-0.4.1.jar， minidns-0.1.1.jar

请遵循代码波纹管：

public class MyConnection implements ConnectionListener { 

    ... 

    XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder(); 
    config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled); 
    config.setUsernameAndPassword(userName + "@" + DOMAIN, password); 
    config.setServiceName(DOMAIN); 
    config.setHost(DOMAIN); 
    config.setPort(PORT); 
    config.setDebuggerEnabled(true); 

    AbstractXMPPConnection mConnection = new XMPPTCPConnection(config.build()); 
    mConnection.setPacketReplyTimeout(10000); 
    mConnection.addConnectionListener(this); 

    try { 
     mConnection.connect(); 
    } catch (SmackException | IOException | XMPPException e) { 
     e.printStackTrace(); 
    } 


    @Override 
    public void connected(XMPPConnection xmppConnection) { 
     Log.d(TAG, "connected"); 

     try { 
       mConnection.login(); 
     } catch (XMPPException | SmackException | IOException e) { 
       e.printStackTrace(); 
     } 
    } 

其他方法，你必须重写：

@Override 
public void authenticated(XMPPConnection xmppConnection, boolean b) { 
    Log.d(TAG, "authenticated"); 
} 

@Override 
public void connectionClosed() { 
    Log.d(TAG, "connectionClosed"); 
} 

@Override 
public void connectionClosedOnError(Exception e) { 
    Log.d(TAG, "connectionClosedOnError" + e.toString()); 
} 

@Override 
public void reconnectionSuccessful() { 
    Log.d(TAG, "reconnectionSuccessful"); 
} 

@Override 
public void reconnectingIn(int i) { 
    Log.d(TAG, "reconnectingIn"); 
} 

@Override 
public void reconnectionFailed(Exception e) { 
    Log.d(TAG, "reconnectionFailed"); 
}
