Cannot get it to work about poi-on-android

[centic9]

If this is still a problem then please paste the full build-output as the one line is likely not the actual cause.

Hi,
the build process in android studio finishes with a lot of errors, but the app gets installed on my phone. When I try to create an excel file, with my app installed on the phone, android studio will show the following errors. https://github.com/andruhon/android5xlsx works for me, that’s why I have stopped trying to get it work.
If you like I could close the issue. Or if you like, I could test some different setups/configurations.
Thank you for your help!

The error message indicates that no XML Parser was found at all, however the poi-shadow.jar should already contain the aalto-xml parser implementation which can be used on Android directly in the shadowed jar.

Maybe you can try to not additionally list the aalto-xml as dependency?

Hi,
attached, you will find the build-Log, the app-crash-log, and the build.gradle. Let me know, what I should change. I did the testing in a new project, to make sure, no other settings are the cause for the crash.

Hi, I'm encountering the same issue: using poi 3.16. The lib creation works fine, building my app as well, but at runtime during sheet production the app crashes with:

The shaded jar includes the aalto-xml parser and tries to include service-files to make Android load this XML parser instead of the com.bea default one.

What exact version of Android is this?

And can you try try the workaround mentioned in AOSP issue 59658 comment 22:

    right click on /src/main (where you have /java and /res folders),
    select New > Folder > Java Resources Folder,
    click Finish (do not change Folder Location),
    right click on new /resources folder,
    select New > Directory
    enter "META-INF" (without quotes),
    right click on /resources/META-INF folder,
    select New > Directory
    enter "services" (without quotes)
    copy any file you need into /resources/META-INF/services

For you, you'd need to copy this file (javax.xml.stream.XMLInputFactory) into /resources/META-INF/services.

Thanks for the quick reaction. Note that the provided test app works fine on the same emulator (the test.xlsx is created). I will first dive into the differences in my app code and the provided test project before trying the steps mentioned above.

[centic9]

Yes, that would be very welcome as I have a few similar reports but cannot reproduce it myself, one likely cause would be some additional dependencies on other third party libs which may cause this.

[peterhav]

Hi @centic9,

I was able to fix my app by adding these 3 lines from the sample application:

            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");

This was not clear from the readme file on the github main page. I guess a short piece of text on the readme might help others!

Thanks for your efforts in providing this fix to make POI available for Android.

Best regards,
Peter

[centic9]

Thanks a lot for the investigation, that makes sense, I added this a while ago and completely forgot about it, sorry for not mentioning this in the README until now.

i would be interested if there is a better way to do this without having to put something like this into the actual application-code!

[albakaly]

Javax is not included in android that is why we face this error, is there a way to use this lib without javax?

[centic9]

See the readme and previous comments above for some system properties which make it work.
