If you use too much code for any android app, the compilation will throw this error. The similar problem is stated and resolved here. You should split the app in parts as a plugin, in the form of a separate APK available for download. That APK would expose some component that the main app would use. There are various app on google play of such kind.

如果您为任何Android应用程序使用太多代码,编译将抛出此错误。这里陈述并解决了类似的问题。您应该将应用程序分成多个部分作为插件,以单独的APK形式下载。该APK将暴露主应用程序将使用的一些组件。这种谷歌游戏上有各种应用程序。

Please note that there are a number of problems when using Apache POI on Android. The one you are hitting can be solved by the so called "multiDex" feature in newer versions of Android.

请注意,在Android上使用Apache POI时存在许多问题。您正在使用的那个可以通过Android的新版本中的所谓“multiDex”功能来解决。

There are currently two projects which try to solve most of the problems for you:

目前有两个项目试图为您解决大多数问题:

https://github.com/andruhon/android5xlsx
https://github.com/centic9/poi-on-android/ (mainted by me)

https://github.com/centic9/poi-on-android/(由我主持)

The first one is currently based on POI 3.12, whereas the second can be re-compiled with newer versions of POI more easily.

第一个目前基于POI 3.12,而第二个可以更容易地使用较新版本的POI重新编译。
