Hello all,

I am Nicolas Raoul, 10 years of wikipedia editing.
I just released this non-official Android app for Wikivoyage offline:
https://play.google.com/store/apps/details?id=org.github.OxygenGuide
Free, open source, of course.

It serves a different purpose than the existing official Wikivoyage app.
It lets people read Wikivoyage even when offline.
Like a paper guidebook, but stored in your phone.

At first run, it downloads OxygenGuide (a ZIP of all Wikivoyage text, 80MB).
Then you can enjoy the articles offline.
Bonus: Offline is much faster, because data is loaded from the SD card, not from the Internet.

Offline is vital for travellers, because roaming is expensive.
Wikimedia's official app is great, but not offline, making it no-go for most travellers... there is a "Save page" feature, but it is difficult to know in advance every place and topic a travel you lead you to. Imagine selecting and cutting pages from a paper guidebook one-by-one... rather take the whole book if it is not heavy, right?
Special:Book generates monolithic A4-sized EPUB files with images, too heavy for a phone if you select more than a few articles.

The app is functional, but ugly and many features could be added.
If anyone is interested, you're very welcome to join the team :-)
If Wikimedia wants to overtake the app, I would be flattered! If not, I just continue as non-official, no worry.
If I violate any trademark or license, please let me know.
Also, any feedback is very welcome!

By the way, non-Android users can also copy the HTML articles manually to their phone/reader/laptop: https://code.google.com/p/oxygenguide

Cheers!
