我正在尝试使用XMPP服务器创建一个基本的消息传递基础设施，并且已经成功地使用Python实现了这一点。在Python上成功发送和接收预定义的小消息。现在，下一个任务是从和Android手机发送类似的消息。注意：我真的不需要Xabber风格客户端提供的完整聊天客户端功能

我是Android新手，并没有真正研究过Java、Eclipse。尽管如此，我还是在安卓系统中使用了一个基本的“Hello World”程序（空白活动模板），并从网站上获取了一些基本的XMPP代码来进行“增强”。因此MainActivity.java程序如下所示：

package com.yantrajaal.pm1324;

import java.io.IOException;

import org.jivesoftware.smack.AbstractXMPPConnection;
import org.jivesoftware.smack.SmackException;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.tcp.XMPPTCPConnection;
import org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
         XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
           configBuilder.setUsernameAndPassword("userid", "xxxxxx");
           //configBuilder.setResource("SomeResource");
           configBuilder.setServiceName("adastra.re");

           AbstractXMPPConnection connection = new XMPPTCPConnection(configBuilder.build());
           // Connect to the server
           try {
            connection.connect();
        } catch (SmackException | IOException | XMPPException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
           // Log into the server
           try {
                connection.login();
            } catch (SmackException | IOException | XMPPException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

我包含的smack库是

/home/hduser/workspace/PM1324/libs/smack-tcp-4.1.4.jar
/home/hduser/workspace/PM1324/libs/smack-android-4.1.4.jar
/home/hduser/workspace/PM1324/libs/android-support-v4.jar
/home/hduser/workspace/PM1324/libs/smack-core-4.1.4.jar

加上

包含这些库并导入各种类后，程序中没有编译时错误：-）

但是，当我在模拟器中执行程序时，程序在启动时立即崩溃（停止工作）。即使是“Hello World”字符串也不会显示

日志的相关部分显示以下内容：

如果您有任何解决此问题的想法，我们将不胜感激。Smack jar应在运行时提供给应用程序，但
android.jar
-已存在于每个android设备上，并且应仅在编译时可供编译器访问
NoClassDefFoundError
表示应用程序找不到smack库，因为它们未包含在目标apk中，因此问题出现在生成配置中。
问题已解决如下。所有smack JAR都已从所有库中物理删除。然后我看了前面的答案这让我想到了。我下载了python3文件，按照说明创建了artifact.csv文件，并运行了python3脚本。这在我的项目文件夹中安装了所有smack 4.1内容

由于其他错误，程序仍无法运行，但NoClassDefFound的问题已解决。
这有帮助吗？第二个问题是通过使用异步任务解决的。。。因为Android不允许从主线程进行网络操作
