无法使用XMPP和aSmack在Android中接收聊天消息

Question

我正在使用XMPP协议在Android中编写聊天客户端。我使用了asmack.jar http://asmack.freakempire.de/。该实现在我测试的普通Java（使用smack.jar）中工作。但在Android中，我只能向其他客户端发送消息（他使用pidgin）并且无法接收来自他的消息。该应用程序成功连接到服务器，登录并在线显示，但根本没有收到任何消息。

当邮件发送给我的客户时，我的processMessage()永远不会被调用，chatCreated()也不会被调用。

您必须为MessageListener实施MainActivity课程才能接收聊天消息
