我已将 .jar 文件添加到我现有的项目中,如http://www.vogella.com/articles/Eclipse/article.html#classpath中所述。
当我尝试运行模拟器时,我最终得到“java.lang.NoClassDefFoundError: com.itextpdf.text.Document”</p>
我的 .classpath 文件:
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="src" path="gen"/>
<classpathentry kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/>
