我有一个用Java制作的全功能聊天客户端。现在我期待在我的Android设备上实现相同的功能。我开始在我的项目中导入ASmack库，我正在检查每个阶段以避免错误。尽管如此，我仍然坚持到了第一步。我的活动无法在ASmack Jar中找到该类，因此我假设我无法继续。
我的简单代码：
package com.test.mypro;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
public class TestProjectActivity extends Activity {
private static final String LOG_TAG = "TESTER";
/** Called when the activity is first created. */
TextView tvHello;
XMPPConnection connection;
ConnectionConfiguration config;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tvHello = (TextView) findViewById(R.id.tvHello);
Log.i(LOG_TAG, "I'm here");
config = new ConnectionConfiguration("prc.p1.im", 5222, "prc.p1.im");
connection = new XMPPConnection(config);
try {
connection.connect();
// tvHello.setText("Connected to XMPP server");
Log.i(LOG_TAG, "Successfully Connected");
} catch (XMPPException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.e(LOG_TAG, "Not Connected");
}
}
}

其他信息：我已导入asmack-android-7.jar库。我的AVD正在运行2.3.3 Android。
我认为由于这个原因我得到了致命的例外。 我在这里错过了什么？非常感谢您的帮助。谢谢。

试试这个
private final static String server_host = "talk.google.com";
private final static int SERVER_PORT = 5222;
private final static String SERVICE_NAME = "gmail.com";
ConnectionConfiguration config = new ConnectionConfiguration( server_host, SERVER_PORT , SERVICE_NAME);
XMPPConnection m_connection = new XMPPConnection(config);
try {
SASLAuthentication.supportSASLMechanism("PLAIN");
config.setSASLAuthenticationEnabled(true);
m_connection.connect();
Roster.setDefaultSubscriptionMode(Roster.SubscriptionMode.manual);
} catch (XMPPException e) {
e.printStackTrace();
}

我找到了解决这个问题的方法。这是由于我对API所做的更新。我从项目属性中删除了导入的ASmack库。 Lib文件夹也丢失了。因此我在项目中创建了一个文件夹（“libs”）并在那里粘贴了ASmack jar。通过清理项目一次，错误得到修复。 谢谢。 Reference
