Since this Post got bumped - I am currently developing an Androidapp.
Current Features are:
Card Search
User Search
Users Sets
Users Friends
Users Tradelist,Whishlist & Inventory
SetView
Spoiler View of Set
Due to the fact, that I am not developing the API on my own (thanks to ToraTora at this point - I hope he is keeping his good work up! ) as well thats just a freetime project (besides of a 40 hour workweek and one day in university, and friends, and girlfriend, and sports and parties...) and I am totally new to Androiddeveloping I cannot estimate a releasedate.
I think it'll be about a month from now. late march/early april till I am able to release an app which I am satisfied with.
Currently everything works like a charm if you know how - so I really need to write a lot of code handling exceptions.
Another fact ist, that I need to implement Features like storing loaded Users/Cards/Sets to internal and external store, enable download Images only via WiFi etc.
Without those, I wouldn't want to release this app. Those last two Points freezes my mind, due to the fact that I have to read a LOT of HowTos and Tutorials before I am able to implement it properly...
I'll keep you up2date
