Question

我一遍又一遍地收到同样的错误信息。起初我认为这是一个超时的问题所以我设置.setPacketReplyTimeout(15000);仍然只是等待更长时间然后显示相同的错误消息。在更深入的调查结果中，我发现这是因为它期待服务器的某些东西（可能是什么？）。我还发现，你可以setRosterLoadedAtLogin(false)，但不清楚如何，因为XMPPTCPConnectionConfiguration没有那种方法，即configBuilder.setRosterLoadedAtLogin(false)。这是一个转储。我想要了解正在发生的事情以及如何解决这个问题。谢谢

我最近几天也开始使用smack4.1，遇到了类似的错误，进行了测试，因为我使用con.disconnect();。在smack 4.1中，我们找不到setRosterLoadedAtLogin()，所以我认为我们关闭连接的时间是错误的。

Answer 2

@Override
    protected void onDestroy() {
        super.onDestroy();
        con.disconnect();
    }

我发现，如果我们在con.disconnect();或onDestroy()中使用onPause()，则不会收到错误Exception reloading roster

也许我在以下代码的项目中找到了正确操作的真正原因：

try {
        ConnectionConfiguration config = new ConnectionConfiguration(OF_HOST, OF_PORT);
        config.setReconnectionAllowed(true);
        config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
        config.setSendPresence(true);
        config.setDebuggerEnabled(true);
        config.setCompressionEnabled(false);

        SASLAuthentication.supportSASLMechanism("PLAIN", 0);

        connection = new XMPPTCPConnection(config);

        Log.i("connection", connection.toString());
        if (connection.isConnected()) {
            connection.disconnect();
        }
        connection.connect();

        return connection;
    } catch (Exception e) {
        e.printStackTrace();
    }
