XMPP连接保持使用的服务，让我的XMPP连接活跃在这里任何时候都得到断开的Android

Question

IM是代码：

public class XMPPService extends Service { 


@Override 
public int onStartCommand(Intent intent, int flags, int startId) { 
    new ConnectionStatus().execute(); 
    return START_STICKY; 
} 

@Override 
public void onCreate() { 
    Log.i("service", "created"); 

} 
public class ConnectionStatus extends AsyncTask{ 

    @Override 
    protected Object doInBackground(Object[] params) { 
     XMPPClient.getConnection().addConnectionListener(
       new AbstractConnectionListener() { 
        public void connectionClosed() { 
         Log.i("connection", "closed"); 

        } 

        public void connectionClosedOnError(Exception e) { 
         Log.i("connection", "closed on error"); 

        } 

        public void reconnectionFailed(Exception e) { 
         Log.i("reconnection", "failed"); 

        } 

        public void reconnectionSuccessful() { 
         if (XMPPClient.getConnection().isAuthenticated()) { 
          Log.i("isauthenticauted : ", String.valueOf(XMPPClient.getConnection().isAuthenticated())); 
          Log.i("reconnection", "succesful"); 
         } else { 
          try { 
           XMPPClient.getConnection().login(new TinyDB(getApplicationContext()).getString("username"), new TinyDB(getApplicationContext()).getString("password")); 
          } catch (XMPPException e) { 
           e.printStackTrace(); 
          } catch (SmackException e) { 
           e.printStackTrace(); 
          } catch (IOException e) { 
           e.printStackTrace(); 
          } 
          Log.i("reconnection", "succesful"); 
         } 
        } 

        public void reconnectingIn(int seconds) { 
         Log.i("reconnectingIn", String.valueOf(seconds)); 
        } 

       } 
     ); 

     return null; 
    } 
} 

@Override 
public IBinder onBind(Intent intent) { 
    // TODO: Return the communication channel to the service. 
    throw new UnsupportedOperationException("Not yet implemented"); 
} 

}

但连接不断定期和我连接断开得到这样的：

org.jivesoftware.smack.SmackException: Parser got END_DOCUMENT event. This could happen e.g. if the server closed the connection without sending a closing stream element 
     at org.jivesoftware.smack.tcp.XMPPTCPConnection$PacketReader.parsePackets(XMPPTCPConnection.java:1148) 
     at org.jivesoftware.smack.tcp.XMPPTCPConnection$PacketReader.access$200(XMPPTCPConnection.java:937) 
     at org.jivesoftware.smack.tcp.XMPPTCPConnection$PacketReader$1.run(XMPPTCPConnection.java:952) 
     at java.lang.Thread.run(Thread.java:818) 

之后，它开始重新连接到服务器上，然后我得到这个：

09-07 17:56:03.916 17754-20996/com.sports.unity D/SMACK﹕ SENT (0):   `09-07 17:56:04.217 17754-20997/com.sports.unity D/SMACK﹕ RECV (0): <?xml version='1.0'?><stream:stream xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' id='2025993121' from='mm.io' version='1.0' xml:lang='en'><stream:features><c xmlns='http://jabber.org/protocol/caps' hash='sha-1' node='http://www.process-one.net/en/ejabberd/' ver='Kyn00yB1iXiJLUJ0gVvn7tZREMg='/><register xmlns='http://jabber` 

如何保持一个稳定的conenction到XMPP服务器

Answer 1

当你的客户端的空闲大于空闲时间，这基本上发生（“空闲连接策略”）在您server.For指定这一点，你需要在您的smack/asmack库中实现XMPP Ping类，其中您必须发送XMPP Pong作为对服务器ping的答复。 而且您还可以实施XMPP重新连接类。
