I need to export excel from my android app. I use Apache-POI library and I get en exception when I run my app "NoClassDefFoundError". But the class is in "poi-ooxml-3.9-20121203.jar" and the jar is connected as external jar. I suppose that it is impossible to use that lib in android development. Any idea or library which can help me for these points:
- 创建 Excel 文件
- 读取并向其中添加行
推荐答案
我也一直在尝试将 Apache POI 用于我的应用程序，我的结论是它具有与 Android 冲突的依赖项.至少，即使付出了相当大的努力，我也无法让它发挥作用.
I have been trying to use Apache POI for my app too and my conclusion was that it has dependencies that conflict with Android. Atleast I was not able to make it work, even with a quite amount of effort.
如果你想导出的excel文件比较简单，我建议用jxl代替.不幸的是，这个库只支持旧的 excel 格式.
If the excel documents you wish to export are rather simple, I would suggest using jxl instead. This library unfortunately only supports old excel formats though.
Lars Vogel 制作了一个很好的教程，展示了如何做到这一点:http://www.vogella.com/articles/JavaExcel/article.html

不使用 POI 的另一个论据是图书馆的大小.它相当大，因此会对您的应用大小产生巨大影响.
Yet another argument for not using POI is the size of the library. It is rather big, hence leaving a huge impact on your app size.
如果您真的想使用 POI，我建议为它创建一个简单的 Web 服务，让您的应用调用它来创建 Excel 文档.
If you really want to use POI, I suggest creating a simple web service for it, having your app call that to create the excel documents.
