Android + Proguard + Apache POI

Question

Someone was able to get the Apache POI library to work after obfuscation. I read a lot of information, tried different methods, but still get the error:

a.a.b.a: Provider com.bea.xml.stream.EventFactory not found
org.apache.poi.openxml4j.opc.internal.marshallers.PackagePropertiesMarshaller.<clinit>(Unknown Source)

at org.apache.poi.xssf.streaming.SXSSFWorkbook.<init>(Unknown Source)

I added the jars files into libs folder: poi-ooxml-schemas-3.12-20150511-a.jar and poi-3.12-android-a.jar.

Necessary System-Properties

In order to work around problems with finding a suitable XML Parser, currently the following system properties need to be set manually during startup of your application (let me know if you know of a better way to do this, see issue #10)

From me : Just put those lines in your code before using the library

System.setProperty("org.apache.poi.javax.xml.stream.XMLInputFactory", "com.fasterxml.aalto.stax.InputFactoryImpl");
System.setProperty("org.apache.poi.javax.xml.stream.XMLOutputFactory", "com.fasterxml.aalto.stax.OutputFactoryImpl");
System.setProperty("org.apache.poi.javax.xml.stream.XMLEventFactory", "com.fasterxml.aalto.stax.EventFactoryImpl");

Download the library

If you want to get started quickly, there is a ready-made jar-file available here https://github.com/centic9/poi-on-android/releases

You should be able to simply add this to your Android project and use the Apache POI classes from it.

Old answer (does not work on Android if ProGuard is enabled)

If you use HSSF

( .xls => Excel '97(-2007) file format) It was not easy but I succeeded. Simply set this dependency to Apache POI (ONLY, remove the libraries add previously ex : poi-ooxml-schemas-3.12-20150511-a.jar and poi-3.12-android-a.jar) :

compile group: 'org.apache.poi', name: 'poi', version: '3.16'

For the latest version see here : https://mvnrepository.com/artifact/org.apache.poi/poi

If you use SXSSF

(.xlsx => Excel 2007 OOXML file format) Add this dependency to your build.gradle

compile files('libs/poi-3.12-android-a.jar')
compile files('libs/poi-ooxml-schemas-3.12-20150511-a.jar')

The ProGuard Rules for both

And for ProGuard just add the rules quote by @PN10 above: https://github.com/centic9/poi-on-android/issues/5#issuecomment-283581644
