Android Oreo Service/Notification problem solved

Guys, if anyone has troubles with Oreo notifications in background (when app is not opened or device is blocked), there is Evernote library I used in 28-29 Chapters to do the same thing as in the book. Here is the solution: https://github.com/bekabot/PhotoGallery/tree/Chapter-29-with-Evernote

@bekabot this link seems to be broken. Can you explain the solution here?
