android - 无法在 Android 中将 XMPP 服务器与 ASmack 连接

Question

我有一个用 Java 制作的功能完备的聊天客户端。现在我期待在我的安卓设备上实现同样的功能。我开始在我的项目中导入 ASmack 库，并在每个阶段进行检查以避免错误。不过，我还停留在第一步。我的 Activity 无法在 ASmack Jar 中找到该类，因此我认为我无法继续。

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");
            }
        }
    }

附加信息:我导入了 asmack-android-7.jar 库。我的 AVD 正在运行 2.3.3 Android。

我假设因此我遇到了致命异常。我在这里错过了什么？您的帮助将不胜感激。谢谢。
