我创建了一个非常简单的 Android 应用程序，只是为了使用功能。在应用程序中，我想调用 Web 服务客户端来检索和显示一些数据。我想我已经成功导入并引用了 jar 文件（即库）。它似乎成功地实例化了该类，但是当该类引用 jar/库中的另一个类时，它会引发类未找到错误。有任何想法吗？？？还有什么我可以提供帮助回答的吗？？？
这是我的代码：
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();
}
});
}
}
这是错误：

注意：我了解 org/tempuri 的问题，并会更正。
