我有我在Java中做了充分的工作聊天客户端。 现在我期待着实现我的Android设备上是相同的。 我开始了与我的项目导入ASmack图书馆，我在每个阶段检查，以避免错误。 我在第一步卡住虽然。 我的活动是不是能找到ASmack罐类，所以我认为我无法继续。
我简单的代码：
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");
}
}
}
logcat的日志：

附加信息：我有asmack-Android的7.jar库中导入。 我的AVD运行2.3.3 Android系统。
我想因为这个，我发现了致命的异常。 我缺少的是在这里吗？ 您的帮助将不胜感激。 谢谢。

这是我的代码，它的工作对我罚款，我希望它有帮助你。 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。 它是由于我对API进行的更新。 我从我的项目属性中删除的进口ASmack库。 lib文件夹不翼而飞了。 因此，我做了一个文件夹（“库”）诠释他的项目并粘贴ASmack罐子那里。 BY一次清洗项目，该错误是固定的。 谢谢。 参考
