我想使用 smack api 和talk.google.com服务器创建一个 android 聊天应用程序，但问题是当我使用 gmail id 和密码创建到 Smack API 的连接并使用“connection.getuser()”检查我的用户名时，我的id 以以下格式显示“anything@gmail.com/Smack_（一些 smack id）”。现在，如果我使用另一部手机从我的应用程序向“anything@gmail.com”发送消息，则不会收到，但如果我将其发送到“anything@gmail.com/Smack _ ” （相同的 smack id )" 已正确收到。
附加的 smack id 是随机的，每次连接时都会发生变化，因此我无法通过任何方式获取它，因此无法发送消息，那么我该如何解决这个问题。
我的 ChatActivity 的代码是：
