java - Android smack 4.1连接问题

我正在尝试使用GoogleTalk与android中的Smack建立连接。
我已经在互联网上跟踪了许多教程示例，但我似乎还是无法使它起作用。

public static final String HOST = "talk.google.com";

public static final int PORT = 5222;
public static final String SERVICE = "gmail.com";
public static final String USERNAME = "[email protected]";
public static final String PASSWORD = "mypassword";

我的上述凭据是正确的...

 XMPPTCPConnectionConfiguration.Builder connConfig = XMPPTCPConnectionConfiguration.builder();
   connConfig.setSecurityMode(ConnectionConfiguration.SecurityMode.required);
   connConfig.setUsernameAndPassword(USERNAME, PASSWORD);
   connConfig.setServiceName(SERVICE);
   connConfig.setHost(HOST);
   connConfig.setPort(PORT);
   connConfig.setDebuggerEnabled(true);
   //setCompressionEnabled(false).build();
   //(HOST, PORT, SERVICE);
   XMPPTCPConnection connection = new  XMPPTCPConnection(connConfig.build());
     try {
       connection.connect();
       Log.i("XMPPChatDemoActivity",  "[SettingsDialog] Connected to "+connection.getHost());
     } catch (XMPPException ex) {
         Log.e("XMPPChatDemoActivity",  "[SettingsDialog] Failed to connect to "+ connection.getHost());
         Log.e("XMPPChatDemoActivity", ex.toString());
         setConnection(null);
     }
     catch(SmackException ex){
         Log.e("XMPPChatDemoActivity",  "[SettingsDialog] Failed to connect to "+ connection.getHost());
         Log.e("XMPPChatDemoActivity", ex.toString());
         setConnection(null);
     }
     catch(IOException ex){
         Log.e("XMPPChatDemoActivity",  "[SettingsDialog] Failed to connect to "+ connection.getHost());
         Log.e("XMPPChatDemoActivity", ex.toString());
         setConnection(null);
     }

我得到java.lang.ExceptionInInitializeError

在这条线上

XMPPTCPConnectionConfiguration.Builder connConfig = XMPPTCPConnectionConfiguration.builder(); //第184行

这是完整的堆栈跟踪：

有人可以帮我吗？我已经在KitKat和JellyBean上对此进行了测试
两者都有相同的例外，因此这对于操作系统版本的上下文不是小问题。我想念什么？

最佳答案

使用SMACK 4.1建立连接时确实遇到问题。
当我包括下面提到的所有这些库时，便成功建立了连接。试试看:)希望你成功。
