我搜索了所有的博客，发现了同样的东西，但我不知道我做错了什么

如果有任何其他方式或解决方案连接Facebook XMPP，请帮助我
尽快

最后，感谢no.good.at.编码代码和harism的建议，我能够连接到Facebook聊天。这段代码是Asmack库（Android的Smack端口）的机制。对于Smack库，必须使用no.good.at.编码机制

apiKey是Facebook应用程序设置页面中给出的API密钥。sessionKey是访问令牌的第二部分。如果令牌的形式为AAA | BBB | CCC，则BBB是会话密钥。sessionSecret是使用旧的RESTAPI和auth.promoteSession方法获得的。要使用它，需要使Http访问此url：

尽管Facebook聊天文档说需要使用你的应用程序密钥，但只有当我使用返回REST方法的密钥时，我才能使它工作。要使该方法有效，必须在应用程序设置的“高级”选项卡中禁用“禁用不推荐的身份验证方法”选项。
