You've received the published item:

<book xmlns="pubsub:test:book"><title>book x</title></book>

You've received the 404 error from "computer" (your xmpp server) for this query:

<query xmlns="http://jabber.org/protocol/disco#info" node="ghost2"></query>

Which hast to do with service discovery. Is it possible that you've removed some messages from the complete conversation?

Edit:

Could you try to replace:

PubSubManager manager = new PubSubManager(connection, "computer");

with this

String pubSubAddress = "pubsub." + connection.getServiceName();
PubSubManager manager = new PubSubManager(connection, pubSubAddress);

Maybe this example can be used as a reference for you：

public void login(String Ip,String username,String passwaord)
     {
         try 
         {
            connConfig = new AndroidConnectionConfiguration(Ip, 5222);
            connection = new XMPPConnection(connConfig);
            connection.connect();  
            connection.login(username, passwaord);
            pubSubAddress = "pubsub."+ connection.getServiceName();
            manager = new PubSubManager(connection,pubSubAddress);
            Log.i("MyError","connection success");  
         }
         catch (XMPPException e) 
         {
             Log.i("MyError","connection failed");      
             e.printStackTrace();
         }

     }

In addition, you may refer to another question which is relevant to yours.

Hope this will help.
