【中文标题】如何使用 xmpp 连接 Facebook 聊天，我想输入朋友的用户名，然后聊天显示 SASL 身份验证失败【英文标题】：How to connect Facebook chat using xmpp,i want to enter username of friends and then chat-showing SASL Authentication failed 【发布时间】：2014-03-26 12:01:47 【问题描述】：我可以连接xmpp for gtalk，但我不知道如何连接xmpp for facebook chat，我搜索了很多，然后我写了一些代码，它也不起作用，
现在我正在尝试这样，用户需要输入他的用户名和密码，然后用户必须输入他的朋友用户名和消息然后聊天。

现在我更新的代码在这些行中抛出 NPE
Message msg = new Message(to, Message.Type.chat);
msg.setBody(text);
connection.sendPacket(msg);
首先它会从那里打开对话框，我们需要输入用户名和密码，然后想输入朋友列表的用户名，然后是味精，然后像这样点击发送，我正在尝试，，，我正在输入用户名称也正确，但单击发送按钮时显示 NUll ponter 异常
【问题讨论】：
尝试清理您的项目，如果清理项目不起作用，则只需重新启动一次 Eclipse 并检查。 是的，我尝试了所有方法 @InnocentKiller，你能检查我的代码是正确还是错误 好的，那么问题可能是您在某处有 2 个 jar 文件，其中包含相同的包和类。 你的项目中有android_maps_lib吗。
不，伙计，我有 android_support4jar,asmack-2010.04.02.jar,asmack-2010.05.07.jar,asmack-issue15.jar,asmack-jse-buddycloud-2010.12.11.jar,httpclient -4.1.3.jar,httpcore-4.1.4.jar,org.xbill.dns_2.1.6.jar,smack.jar,smackx.jar,smackx-debug.jar,smackx-jingle.jar,xpp3-1.1.4c .jar，我有这么多，如果我删除一个它会在代码中的某处显示错误@InnocentKiller
【参考方案1】：
我认为问题可能是您在某处有 2 个 jar 文件，其中包含相同的包和类。因此，我强烈建议您再次检查所有 jar 文件并删除导致问题的任何人。
从其中一个 JAR 文件中删除此包将解决问题。
【讨论】：
Dalvik format failed with error 1 这个问题解决了，感谢您的回答，但是如何使用 xmpp 连接 facebook 聊天 @KarthickM，我对此一无所知，真的很抱歉。【参考方案2】：有一个官方Facebook Chat API documentation，您在实现聊天客户端时需要遵循它 - 要对用户进行身份验证，您需要向他展示 WebView 表单，他在 Facebook 上对您的应用程序进行身份验证，获取身份验证令牌，然后 strong> 令牌将用于 X-FACEBOOK-PLATFORM SASL 机制。
【讨论】：
autentical token 你是在说 apikey 和 accesstoken 请阅读完整的身份验证流程说明：api 密钥和访问令牌是您在连接到 facebook 时提供的，而身份验证令牌是 facebook 在允许您的应用访问他的 Facebook 帐户时给用户的。 ，你有没有关于如何连接facebook xmpp聊天的示例或完整代码 为了登录，我们必须像这样 example@gmail.com 或 example@chatfacebook.com以上是关于如何使用 xmpp 连接 Facebook 聊天，我想输入朋友的用户名，然后聊天显示 SASL 身份验证失败的主要内容，如果未能解决你的问题，请参考以下文章
