我在 Android 上有一个项目，需要使用 asmack 库来启用实时聊天。

关键功能是重新连接机制，这意味着我的应用程序可以在互联网连接丢失时自动重新连接。

这是我的代码片段：

ConnectionConfiguration connConfig = new ConnectionConfiguration(HOST, PORT);
connConfig.setSASLAuthenticationEnabled(true);
connConfig.setReconnectionAllowed(true);
XMPPConnection connection = new XMPPConnection(connConfig);

但是每当我关闭然后打开 Wifi 时，我都会收到此错误：

谁能解决这个错误，请帮助我！

使用最新的 smack api - 我使用的是 4.1.0

然后设置重新连接，如下所示：

ReconnectionManager manager = ReconnectionManager.getInstanceFor(connection);
manager.enableAutomaticReconnection();

它将按照此处所述自动重新连接

Asmack 正确支持重新连接，唯一的问题是您正在使用 SASL 连接，所以这会出现问题，因为您在关闭 Wi-Fi 时再次尝试相同的连接。尝试使用 set SASL false

connConfig.setSASLAuthenticationEnabled(false);

需要其他方式手动断开

connection.disconnect();

在开始设置所有内容时，请致电

ReconnectionManager.setEnabledPerDefault(true);

然后从那时起创建的连接将自动重新连接。

Don't use reconnection mechanism which is implemented in ASMACK.

Use:

    connConfig.setReconnectionAllowed(false);

Instead, you should create BroadcastReceiver which listens to ConnectivityManager.CONNECTIVITY_ACTION. When connection to WIFI or other network is occurred, then you will receive the callback onReceive in your BroadcastReceiver.
