XMPP aSmack - 我怎麼能聽我自己的用戶狀態（在線/離線）重新連接

Question

我是新來的xmpp/asmack在android中，我正在尋找一種方法來偵聽我自己的用戶狀態和存在變化服務器。

我的目標是恢復連接，如果丟失。

我使用花名冊來幫助我獲得朋友的存在，但實際上並不是當前用戶本身。

任何幫助，將不勝感激:)

最好的問候，

您必須啓用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看起來是這樣的：

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");  
     } 

    }
