帶有XMPP的Android聊天應用

Question

我正在嘗試設置一個Android facebook聊天應用程序。 我已經實現了XMPP許可的Facebook登錄。

現在，如果我只想測試asmack.jar的基本連接設置，則會收到此錯誤消息

12-18 21:29:48.845: E/AndroidRuntime(5516): FATAL EXCEPTION: main
12-18 21:29:48.845: E/AndroidRuntime(5516): java.lang.NoClassDefFoundError: org.jivesoftware.smack.ConnectionConfiguration
12-18 21:29:48.845: E/AndroidRuntime(5516): at com.example.messenger.MainActivity.testXMPP(MainActivity.java:68)

這是我的代碼。 希望有人能幫忙。 （該錯誤是在TestXMPP中引起的）

將asmack庫放在libs文件夾中。
