android - 将库添加到 eclipse

Question

我想添加一个库(PDFBox:http://pdfbox.apache.org/download.html)。但我想我做错了什么。我做了:项目>属性>java构建路径>添加外部JAR>pdfbox-1.7.0.jar。但是每当我在模拟器中启动我的项目时，我都会收到此错误(logcat)

所以它找不到我从附加库导入的类。当我在 java 构建路径屏幕中打开 .jar 时，它会显示以下内容:

来源附件:(无)

Javadoc 位置:(无)

native 库位置:(无)

访问规则:(无限制)

这正常吗？

有人可以准确地告诉我需要从该网站 (http://pdfbox.apache.org/download.html) 下载哪些文件以及我必须在哪个屏幕中添加哪些文件以及如何添加。

谢谢!

Answer 1

自 ADT r17 起，您不应再像这样将库文件添加到项目中。现在，这由 ADT 自动处理。

为了将外部库添加到您的项目中，您必须在项目的根文件夹(src 文件夹所在的文件夹)中创建一个名为 libs 的文件夹位于)。下一步是将所有库(jar)复制到该文件夹​​。剩下的事情会自动为您完成。无需编辑构建路径等。
