无法使用aSmack 4.0.2建立新连接

解决方案是将连接代码放入单独的线程中。

public static final String HOST = "208.68.163.218"; //write your host namepublic static final int PORT = 5222;@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    connect();}public void connect() {    Thread t = new Thread(new Runnable() {        @Override        public void run() { Context context = getApplicationContext(); SmackAndroid.init(context); ConnectionConfiguration ConnectionConfiguration = new ConnectionConfiguration(HOST, PORT); ConnectionConfiguration.setDebuggerEnabled(true); XMPPConnection connection = new XMPPTCPConnection(ConnectionConfiguration); try {     connection.connect(); } catch (ConnectionException e) {     e.printStackTrace(); } catch (SmackException e) {     e.printStackTrace(); } catch (IOException e) {     e.printStackTrace(); } catch (XMPPException e) {     e.printStackTrace(); }        }    });    t.start();}
