我试图制作一个使用XMPP将消息发送到Gmail帐户的应用程序。我找到了一个提到谷歌XMPP服务器名称的链接，但我不认为我能够建立连接。使用smack的Android XMPP：服务器没有响应
编辑我改变了服务器的名称，我相信它能够建立连接。但它表示Rosters有0个条目。我正尝试使用Gmail帐户登录。新的异常我：

这里是我的代码：
ConnectionConfiguration config = new ConnectionConfiguration("xmpp.l.google.com", 5222);
XMPPConnection connection = new XMPPConnection(config);
try {
Log.d("Smack", "Start Connect");
connection.connect();
Log.d("Smack", "Start Login");
connection.login(user, pwd);
Roster roster = connection.getRoster();
//Get all rosters
Collection<RosterEntry> entries = roster.getEntries();
//loop through
Log.d("Smack", "Start Rosters");
for (RosterEntry entry : entries) {
//example: get presence, type, mode, status
Presence entryPresence = roster.getPresence(entry.getUser());
String status = entryPresence.getStatus();
Toast.makeText(context, status, Toast.LENGTH_LONG).show();
Log.d("Smack", "Print rosters");
}
Log.d("Smack", "End Rosters");
} catch (XMPPException e) {
// TODO Auto-generated catch block
Log.e("Smack", "Error: " + e.getMessage());
e.printStackTrace();
}
你有没有试着用比谷歌的其他XMPP服务器上测试它？谷歌正在开始从XMPP切换到环聊应用的新协议。 **请尝试xmpp.l.google.com，并告诉我它是否有效** – Vannen
我尝试过使用该服务器，并且收到了上面发布的异常。我只是使用错误的谷歌服务器？我目前正在尝试使用Google帐户登录。 – AndroidDev93
有一个名为Beem的项目，它也使用asmack进行XMPP连接，并且它是开源的。你可以尝试一下，看看它是否仍然适用于Google Talk。 ** http：//beem-project.com/projects/beem/files ** – Vannen
