我正在尝试使用 Smack 在 Android 中与 GoogleTalk 建立连接。
我已经按照互联网上的大量教程示例进行操作，但似乎仍然无法使其工作。
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 = "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="ed809488808c8481ad8a808c8481c38e8280" rel="noreferrer noopener nofollow">[email protected]</a>";
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:

有人可以帮我解决这个问题吗？我已经在 KitKat 和 JellyBean 上进行了测试
两者都有相同的异常，因此这不是操作系统版本上下文的故障。我缺少什么？
最佳答案
我在使用 SMACK 4.1 建立连接时确实遇到问题。 当我包含下面提到的所有这些库时，我成功建立了连接。尝试一下:)希望你成功。
- jxmpp-core-0.4.1
- jxmpp-util-cache-0.4.1
- minidns-0.1.1
- smack-android-4.1.0.jar
- smack-android-extensions-4.1.0
- smack-core-4.1.0
- smack-extensions-4.1.0
- smack-im-4.1.0
- smack-tcp-4.1.0
关于java - Android smack 4.1 连接问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29727997/
