Unable to find classes in Android library file

I have created a very simple Android app just to work with functionality. Within the app I would like to call a web service client to retrieve and display some data. I think I have succesfully imported and referenced the jar file (i.e. library). It appears to be instantiating the class successfully but when that class is referencing another class within the jar/library it throws a class not found error. Any ideas??? Anything else I can provide to help answer???

Here is my code:

package mhcs.android.ehd;

import mhcs.services.client.EHD.EHDClient;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

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

        String title = getString(R.string.title);
        setTitle(title); // done so that we can change the default title
        //get handles to editText and button widgets
        final EditText eText = (EditText) findViewById(R.id.editText1);
        final Button button = (Button) findViewById(R.id.button1);
        eText.setText(client.getTicketDescription("MMLZ-8LVRMK"));

        button.setOnClickListener(new Button.OnClickListener(){
            @Override
            public void onClick(View v) {
                //get the String entered into the editText widget
                CharSequence editText = eText.getText();
                //display the toast
                Toast.makeText(GetTicketDescription.this, editText, Toast.LENGTH_LONG).show();
            }
        });
    }
}

Here is the error:

回答1:

Find Properties -> Java Build Path -> Order and Export
Change Android Dependencies order

回答2:

Try to create a new folder called libs under your project and put the .jar file there...

回答3:

I had the same problem, I tried to mark the Android Private Libraries under Order and Export and it didn't work for me. Then I noticed that my libs folder wasn't referenced under the Java Build Path. So I just added it to Libraries and it worked.

回答4:

Go to Project> Build Path >Configure Build Path

Check the Libraries you wanted and hit ok
