XMPP aSmack - 我怎么能听我自己的用户状态（在线/离线）重新连接

Question

我是新来的xmpp/asmack在android中，我正在寻找一种方法来侦听我自己的用户状态和存在变化服务器。

我的目标是恢复连接，如果丢失。

我使用花名册来帮助我获得朋友的存在，但实际上并不是当前用户本身。

任何帮助，将不胜感激:)

最好的问候，

您必须启用ReconectionManager。

例子：

XmppManager.config = XMPPTCPConnectionConfiguration.builder() 
      .setServiceName(serverName) 
      .setHost(server) 
      .setPort(port) 
      .build(); 

    connection = new XMPPTCPConnection(config); 

ConnectionListener connectionListener = new ConnectionListener(){...}; // 
connection.addConnectionListener(connectionListener); 

int RECONNECTION_ATTEMPT_SECONDS = 60; 

ReconnectionManager.getInstanceFor(connection).enableAutomaticReconnection(); 
ReconnectionManager.getInstanceFor(connection).setFixedDelay(RECONNECTION_ATTEMPT_SECONDS); 

ReconnectionListener看起来是这样的：

public class ReconnectionListener implements ConnectionListener 
    { 

     @Override 
     public void reconnectionSuccessful() 
     { 
      System.out.println("Connection to chat server restored - You are again online"); 

    //additional foo when connection restored 
     } 

     @Override 
     public void reconnectionFailed(Exception e) 
     { 
      System.out.println("Impossible to reconnect, Chat Server seems to be still unavailable"); 

     } 

     @Override 
     public void reconnectingIn(int seconds) 
     { 
      System.out.println("reconnectingIn fired "+seconds); 
     } 

     @Override 
     public void connectionClosedOnError(Exception e) 
     { 
      System.out.println("Connection closed, Chat Server become unavailable"); 
    //additional foo when connection lost (message to user ?) 
     } 

     @Override 
     public void connectionClosed() 
     { 
      // "XMPP connection was closed."); 
      System.out.println("Connection closed, Chat Server become unavailable"); 
     } 

     @Override 
     public void connected(XMPPConnection connection) 
     { 
      System.out.println("connected fired - reconnection management enabled"); 
     } 

     @Override 
     public void authenticated(XMPPConnection connection, boolean resumed) 
     { 
      System.out.println("authenticated fired");  
     } 

    }
