In my case, it works only if your app contains these libraries:

compile files('libs/dom4j-1.6.1.jar')
compile files('libs/stax-api-1.0.1.jar')
compile files('libs/xmlbeans-2.6.0.jar')
compile files('libs/poi-3.10.1-20140818.jar')
compile files('libs/poi-ooxml-3.10.1-20140818.jar')
compile files('libs/poi-ooxml-schemas-3.10.1-20140818.jar')

You can download them here: here, all in the 'poi-bin-3.10.1-20140818.zip' archive.

And please do not try to install a newer version, it will not work (at least for Android), only 3.10.1 and lower.
