There is however an official Android OneDrive app. So I installed an virtual android instance on my Linux workstation and logged in with the Onedrive app...but boom. The Ondrive app will store files locally, but not in the way of the Desktop app. Each file is named something random which is indexed by some database file, and the directory structure is not maintained at all. Making it pretty much unusable without some fix.
Its infuriating. A smart programmer might be able to make an interface that translates their directory system to the real one, but ugh.
