java.lang.NoClassDefFoundError的：com.itextpdf.text.Document [英] java.lang.NoClassDefFoundError: com.itextpdf.text.Document

问题描述

在 HTTP说明我已经添加了.jar文件到我现有的项目//www.vogella.com/articles/Eclipse/article.html#classpath 。

当我尝试运行模拟器我结束了java.lang.NoClassDefFoundError的：com.itextpdf.text.Document

我的.classpath文件：

 ＆LT;＆类路径GT;
        ＆LT; classpathentry样=SRC路径=SRC/＆GT;
        ＆LT; classpathentry样=SRC路径=根/＆GT;
        ＆LT; classpathentry样=CON路径=com.android.ide.eclipse.adt.ANDROID_FRAMEWORK/＆GT;

解决方案

有关未知的原因，通过月食接口获取罐子Java库不起作用。手动复制/过去到libs文件夹的伎俩。 THX到PARTH多希建议。

I have added the .jar files into my existing project as described in http://www.vogella.com/articles/Eclipse/article.html#classpath .

When I try to run the emulator I end up with "java.lang.NoClassDefFoundError: com.itextpdf.text.Document"

My .classpath file :

<classpath>
        <classpathentry kind="src" path="src"/>
        <classpathentry kind="src" path="gen"/>
        <classpathentry kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/>
        <classpathentry kind="con" path="com.android.ide.eclipse.adt.LIBRARIES"/>
        <classpathentry kind="lib" path="lib/itext-pdfa-5.3.3-javadoc.jar"/>
        <classpathentry kind="lib" path="lib/itext-pdfa-5.3.3-sources.jar"/>
        <classpathentry kind="lib" path="lib/itext-pdfa-5.3.3.jar"/>
        <classpathentry kind="lib" path="lib/itext-xtra-5.3.3-javadoc.jar"/>
        <classpathentry kind="lib" path="lib/itext-xtra-5.3.3-sources.jar"/>
        <classpathentry kind="lib" path="lib/itext-xtra-5.3.3.jar"/>
        <classpathentry kind="lib" path="lib/itextpdf-5.3.3-javadoc.jar"/>
        <classpathentry kind="lib" path="lib/itextpdf-5.3.3-sources.jar"/>
        <classpathentry kind="lib" path="lib/itextpdf-5.3.3.jar"/>
        <classpathentry kind="output" path="bin/classes"/>
</classpath>

MainActivity.java

package com.example.tmp;

import java.io.FileOutputStream;

import com.itextpdf.text.Document;
import com.itextpdf.text.pdf.PdfWriter;

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

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

          String FILE = "/home/ronline/Desktop/FirstPdf.pdf";
        try {
            Document document=new Document();
              PdfWriter.getInstance(document, new FileOutputStream(FILE));
              document.open();
              document.close();
            } catch (Exception e) {
              e.printStackTrace();
            }

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}

解决方案

For unknown reason getting the jars to Java Library through eclipse interfaces doesn't work. Manual copy / past into libs folder does the trick. Thx to Parth Doshi suggestion.
