Android/Eclipse Error - “Could not find class 'org.jivesoftware.smack.ConnectionConfiguration', referenced from method”

问题

This is my first time working with Android/Java. I am trying to run this basic code and I keep getting the following error:

"Could not find class 'org.jivesoftware.smack.ConnectionConfiguration', referenced from method"

My code:

package message.pack;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;

import android.app.Activity;
import android.os.Bundle;

public class ThesimpleigniteandroidActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

    }

              public static void main(String[] args) {
              ConnectionConfiguration conf = new     ConnectionConfiguration("jabber.com",5222);
              XMPPConnection connection = new XMPPConnection(conf);
                  try {
                  connection.connect();
                  connection.login("myusername", "mypassword");
                  } catch (XMPPException e) {
                  e.printStackTrace();
                  } finally {
                          connection.disconnect();
                  }
                  }
                  }

I am using the smack.jar from this page:

Can anyone tell me what I am doing wrong?

回答1:

This is similar to many related problems surrounding External jars in android projects (especially with the new sdk tools). The solution is for you to create a folder in your project called libs and copy the jars into that folder.

回答2:

Did you put the jar file in your eclipse path?

This will tell you how to do so: http://www.wikihow.com/Add-JARs-to-Project-Build-Paths-in-Eclipse-(Java)
