Support Android 4.4

[SenorSmartyPants]

I know that Google's support for this version is dropping (dropped?) But it would be great as I have some 4.4 tablets.

I have no idea how much work it would be to continue to support 4.4.

Thank you for all your efforts on jellyfin.

I downloaded all versions of the 0.9.0 release from https://repo.jellyfin.org/releases/client/android/

None of them will install. I get a Parse error. "There was a problem parsing the package."

I also followed the new link to the play store. It reports that my 4.4 device is not compatible with the app.

I've just tried to launch the app on a Android 4.4 KitKat emulator but unfortunately it looks like the Jellyfin JavaScript code isn't compatible with the old webview provided by Android 4.4.

I found a similar problem on StackOverflow and it appears that using Babel could solve this, but I personally don't have enough web & npm knowledge to try that ;)

@z3ntu at the time we weren't sure if there were other issues. We have a pull request open right now for CoreJS support so you could maybe run some tests after that gets merged.

Is this fixed by https://github.com/jellyfin/jellyfin-web/pull/862 ?

It seems to be a different error now

And line 89 of ./platforms/android/app/src/main/assets/www/plugins/org.jellyfin.mobile/www/apphost.js is let container = item.Container; so I assume it doesn't like the let keyword

Okay so I've added

to the jellyfin-web repo and rebuilt again. Now it seems to complain about dependencies not being transpiled essentially

I'm not really sure what I'm doing but it doesn't feel like progress :man_shrugging: Some help please? :)
