我試圖製作一個使用XMPP將消息發送到Gmail帳戶的應用程序。我找到了一個提到谷歌XMPP服務器名稱的鏈接，但我不認爲我能夠建立連接。使用smack的Android XMPP：服務器沒有響應
編輯我改變了服務器的名稱，我相信它能夠建立連接。但它表示Rosters有0個條目。我正嘗試使用Gmail帳戶登錄。新的異常我：

這裏是我的代碼：
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();
}
你有沒有試着用比谷歌的其他XMPP服務器上測試它？谷歌正在開始從XMPP切換到環聊應用的新協議。 **請嘗試xmpp.l.google.com，並告訴我它是否有效** – Vannen
我嘗試過使用該服務器，並且收到了上面發佈的異常。我只是使用錯誤的谷歌服務器？我目前正在嘗試使用Google帳戶登錄。 – AndroidDev93
有一個名爲Beem的項目，它也使用asmack進行XMPP連接，並且它是開源的。你可以嘗試一下，看看它是否仍然適用於Google Talk。 ** http：//beem-project.com/projects/beem/files ** – Vannen
