Hi guys, great work with Fuse Tools, keep it up! Question, can I use the Spotify Android SDK (https://developer.spotify.com/technologies/spotify-android-sdk/) in fuse? Thanks!
short answer: Yes!
long one: To implement a third party SDK you need to dive into Foreign Code and Uno to build a layer above the Spotify SDK. The good thing is that are plenty community projects to help you to understand, Fuse.Firebase is one of my favorites.
There is even a tutorial that implements a native facebook login.
