如何使用Smack與Android Studio與Openfire XMPP服務器聯網

我是Android編程的新手，大約兩個月了。在發佈之前，我花了相當多的時間試圖找出解決方案。所以，我會直接回答這個問題，之後，我會解釋什麼對我沒有幫助。如何使用Smack與Android Studio與Openfire XMPP服務器聯網

的問題如下（這是按標題）：

如何使用啪4.1.5與Android 2.1.2工作室網絡與Openfire的XMPP服務器4.0.2？理想情況下，讚賞，登錄和發送和接收聊天簡短，骨頭的代碼片段將不勝感激。否則，強烈的指針將是最受歡迎的。（我是否遺漏了一個庫？是否有錯誤的try-n-catch？）

MainActivity.java文件如下所示（爲了放大問題，我已經註釋掉了最後一段代碼代碼，最好的我可以告訴，問題出現在註釋開始之前的那一行（/ *），然而，這很奇怪，因爲這一行實際上和Smack文檔建議的一樣，所以我要求幫助，讓我在這裏說：「提前致謝」。）

（因爲我已經得到了一臺Openfire XMPP服務器並運行在我的PC上，我還測試了Openfire XMPP服務器上的火花，發送和接收的聊天沒關係。）：

我已經設置了應用的build.gradle導入所有適當的庫（或至少我覺得我有）。它們包括：

<Android API 24 Platform> 
<1.8> 
android-android-24 
animated-vector-drawable-24.0.0 
appcompat-v7-24.0.0 
hamcrest-core-1.3 
junit-4.12 
jxmpp-core-0.4.2 
jxmpp-util-cache-0.4.2 
minidns-0.1.7 
smack-android-4.1.5 
smack-android-extensions-4.1.5 
smack-core-4.1.5 
smack-extensions-4.1.5 
smack-im-4.1.5 
smack-java7-4.1.0 
smack-resolver-javax-4.1.0 
smack-resolver-minidns-4.1.5 
smack-sasl-javax-4.1.0 
smack-sasl-provided-4.1.5 
smack-tcp-4.1.5 
support-annotations-24.0.0 
support-v4-24.0.0 
support-vector-drawable-24.0.0

以上是與問題相關的基本信息。

以下是發佈此問題之前我嘗試做的「作業」。

我已經翻遍了Smack文檔的每個單詞（http://download.igniterealtime.org/smack/docs/latest/documentation/）。最初，我使用「的幾行代碼」嘗試建議的文件中：

（http://download.igniterealtime.org/smack/docs/latest/documentation/overview.html）

不幸的是，沒有快樂可言。

然後，我試圖測試一行：（Ha-ha-ha。Stack Overflow說我想引用的代碼看起來像垃圾郵件，所以我把它放在原處，現在它不再有趣了，前面的句子看着垃圾郵件到SO，讓我們看看這兩個句子是否允許我通過這篇文章。）（哈哈。堆棧溢出說我需要至少10個聲望發佈超過2個鏈接，所以鏈接我不管怎麼說，我從Smack文檔的「Getting Started」頁面說了一行代碼。）

仍然是徒勞的。

相信我，我嘗試了所有其他解決方案在網絡上建議（包括堆棧溢出其他地方），但我失敗了所有的人。每次都會出現一些錯誤信息或其他信息。或者，給出的代碼樣本將需要比我必須做的更多的編碼排序。例如，代碼示例可能引用了一個沒有定義的方法或者不得不自己創建的類。

所以，再次，在此先感謝任何幫助。

從你的依賴 – babadaba

刪除咂嘴，旋轉變壓器的javax-4.1.0我想你導入了很多，你不需要的東西，試試這個編譯「org.igniterealtime.smack：咂嘴，安卓4.1 .6' compile'org.igniterealtime.smack：smack-tcp：4.1.6' compile「org.igniterealtime.smack：smack-extensions：4.1.6」 compile「org.igniterealtime.smack：smack-im： 4.1.6" –

使用Android庫

org.igniterealtime.smack：咂嘴，安卓4.1.6
org.igniterealtime.smack：咂嘴-TCP：4.1.6
org.igniterealtime.smack ：smack -im：4.1.6

這些庫足以開始使用。所有java庫都與android不兼容，特別是javax包。

我與Smack 4.1.x（InitialDirContext上的NoClassDefFoundError）有同樣的問題。

嘗試使用啪4.2，中的build.gradle：

compile "org.igniterealtime.smack:smack-android-extensions:4.2.0-alpha3" 
    compile "org.igniterealtime.smack:smack-tcp:4.2.0-alpha3"

這是我的初始化連接。

private void initializeConnection() { 
    try { 
     XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder() 
       .setHost(mServerAddress) 
       .setPort(mServerPort) 
       .setXmppDomain(JidCreate.domainBareFrom(mServiceName)) 
       .setUsernameAndPassword(mUserLogin, mUserPassword) 
       .build(); 

     mXmppTcpConnection = new XMPPTCPConnection(config); 

     XmppConnectionListener connectionListener = new XmppConnectionListener(); 
     mXmppTcpConnection.addConnectionListener(connectionListener); 
    } catch (XmppStringprepException e) { 
     e.printStackTrace(); 
    } 
}
