android - ASmack多用户聊天室

我正在使用Asmack API在android上创建多用户聊天室，我想通过使用获取所有托管室

MultiUserChat.getHostedRooms(connection, service)

并继续获取错误，如下所示：


  引起原因：java.lang.ClassCastException：org.jivesoftware.smack.util.PacketParserUtils $ 2


我进行了很多搜索，但仍然对如何解决这个问题一无所知。

在我拔出头发之前，任何帮助将不胜感激。

谢谢

最佳答案

登录前调用此函数。这增加了asmack未命中的许多功能。我听说asmack 4+不需要这个。我不确定。

public void configure(ProviderManager pm) {
