asmack中的ReconnectionManager

Question

我有一个在Android上的项目，这需要使用一个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中断时自动重新连接。

下面是我的代码片段：

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

但每当我关闭Wifi然后打开Wifi时，我都会收到这个错误：

任何人，谁能解决这个错误，请帮助我！

Answer 1

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();

它将按照描述的Here自动重新连接

Answer 2

Asmack支持重新连接正确，唯一的问题是您正在使用SASL连接，所以这是给出问题，因为您正在尝试相同的连接再次打开Wi-Fi off.Try与设置SASL假

connConfig.setSASLAuthenticationEnabled(false);

否则需要手动断开连接

connection.disconnect();

Answer 3

在开始设置所有内容时，调用

ReconnectionManager.setEnabledPerDefault(true);

然后，从那时起创建的连接将自动重新连接。
