我正在嘗試爲Android（使用Java連接到C＃/ Unity）開發XMPP聊天客戶端。我已經得到了Java - > Unity/C＃連接的完美工作。我也下載了Asmack，並可以生成一個庫和我的封裝類來初始化與OpenFire XMPP服務器的連接。但是，我似乎無法獲得Presence的發送或接收。我可以登錄，註冊新用戶並填寫他們的名單，發送消息，但不能發送任何消息。無法通過ASmack發送或接收狀態
代碼自動註冊從未使用過此應用程序的用戶。它還使用預設的好友列表，並自動使用這些朋友填充名單。通過設置存在監聽和通過獲取

存在以兩種方式檢查：
的代碼是如下（抱歉所有調試線，不能使用Unity時使用斷點）登錄後的狀態。這個SO頁面建議等5秒後才能獲得版本號：Unable to get presence of roster by using smack, openfire 我已經嘗試過，並且通過從一個按鈕中調用getOnlineFriends，並在登錄後超過5秒鐘。聽衆永遠不會被叫到。它只是登錄後觸發一次，每次在陣容中都有一個存在= null。
編輯：上Asmack開機調試模式後，我看到了如下答覆我的存在發送消息：
SENT <presence id="3sG7l-11"><status>Online, Programmatically!</status><priority>24</priority></presence>
RCV <presence id="6s7BX-5" to="[email protected]/Smack" from="10000063946242" type="error">
<error code="404" type="cancel">
<remote-server-not-found xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/>
</error></presence>

我也試圖通過沿setSendPresence = true傳遞給Connect（）中傳遞的連接配置，但沒有區別。
我也嘗試在OpenFire服務器上手動設置訂閱模式爲「both」（來自「none」）兩個用戶，但沒有任何效果。
也許是最新版本中的錯誤？ ：S http://community.igniterealtime.org/thread/43986 – Sunkas
我最近的線索是名單上的jid格式錯誤。但從「id」更改爲「[email protected]」沒有幫助:( – Sunkas
