YotaPhone2 SDK missing?

(excuse the links, I don't have 10 posts so I wasn't allowed to post them obscured)
Hi, I want to start building some apps so I looked at the developer page:
http___://mwiki.yotaphone.com/wiki/Install_SDK
It tells me to add this xml to Eclipse/Android Studio - ftp:____//http://ift.tt/1Xupxxe
But that file is empty...
Does anyone have a link for the SDK?

Thanks, I appreciate it :)

whoops, embarrassing, I switched to yet another different location on my VPN and it now finally works... :)
