我在xmpp上使用asmack庫進行android聊天。以下是我用來連接到服務器的代碼。但該應用程序無法連接到服務器。 XMPPException服務器沒有響應。不過，我可以從桌面聊天登錄。我無法得到什麼問題。這是我用過的代碼。無法連接到服務器。 XMPPException服務器沒有響應

嘗試使用斷點調試您的代碼並確保服務器正在運行 –
實際上您已連接到服務器。看到這一行 - > 06-26 11：37：47.508：I/MyActivity（421）：連接到mail.speedymx.comconnection是securedfalse –
試圖..錯誤是在connection.login（）。我只是想知道是否有東西丟失。是通過手動從桌面登錄來確保服務器正在工作 – user3643355
