One of things you can do on Android is to enter "intent-filter" values in the manifest which indicates what types of data your application can handle. These xml entries allow you to specify the uri scheme, mimeType, etc. Spotify most likely set up an intent filter to match on a uri that contains https://open.spotify.com so that their app will trigger instead of a browser. I use these intent filters in MobileSheetsPro so that my app is listed as one that supports, pdf, images, chord pro, text files, .msf files and .mss files.
