快速blox使用Smack庫連接

Question

它不斷給我錯誤在xmppConnection.connect（）;

public static final String CHAT_SERVER = QBChatUtils.getChatServerDomain(); 
public void getusers() 
{ 
    XMPPConnection xmppConnection = new XMPPConnection(CHAT_SERVER); 
    try { 
     // Chat action 1 -- create connection. 
     Connection.DEBUG_ENABLED = true; 
     xmppConnection.connect(); 
     xmppConnection.login(chatLogin, password); 
     Roster roster = xmppConnection.getRoster(); 
     Collection<RosterEntry> entries = roster.getEntries(); 
     Presence presence; 

     for(RosterEntry entry : entries) { 
      presence = roster.getPresence(entry.getUser()); 

      System.out.println(entry.getUser()); 
      System.out.println(presence.getType().name()); 
      System.out.println(presence.getStatus()); 
     } 
    } catch (XMPPException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
} 

錯誤報告是這樣

你不能爲此你必須使用Services或AsyncTask後臺運行或長期運行過程中主要還是UI線程。
