Question

我对android有点新意我正在尝试构建一个聊天android应用程序使用openfire作为服务器并使用4.1.6 libs 现在我正在尝试建立一个基本的连接我正在遵循smack文档

    XMPPTCPConnectionConfiguration.Builder conf = XMPPTCPConnectionConfiguration.builder();
    conf.setUsernameAndPassword("user", "user");
    conf.setResource("android");
    conf.setServiceName("my_ip_adress");
    conf.setHost("my_ip_adress");
    conf.setPort(5222);
    conf.setSecurityMode(ConnectionConfiguration.SecurityMode.ifpossible);


    AbstractXMPPConnection connection=new XMPPTCPConnection(conf.build());
    try {
        Log.e("CONNECTION====>", "try");
        connection.connect();
        Log.e("CONNECTION====>", "success");
        connection.login();
        Log.e("LOGIN====>", "success");
    } catch (SmackException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (XMPPException e) {
        e.printStackTrace();
    }

Answer 1

检查您的手机或模拟器是否具有互联网连接

private boolean isNetworkAvailable() {
ConnectivityManager connectivityManager 
  = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}

Answer 2

嗨，如果将来帮助任何人我已经将ConnectionConfiguration.SecurityMode设置为禁用，并且工作正常

var map1 = Immutable.Map({a:1, b:2, c:3, d:4});
var map2 = Immutable.Map({c:10, a:20, t:30});
var obj = {d:100, o:200, g:300};
var map3 = map1.merge(map2, obj);
// Map { a: 20, b: 2, c: 10, d: 100, t: 30, o: 200, g: 300 }

Android XMPP基本连接
