The iOS and Android versions of Gospel Library (Gospel Library 4) pull from the same content lane, so if it's available on one, it should be available on the other. As long as you're on a good internet connection, the app will check for a catalog update every 12 hours, after a period of inactivity where the OS hibernates it in the background, or after force-closing the app by swiping it out of your recent apps, whichever comes sooner. On Android, you can also check for a catalog update by pulling down on the main library screen (you'll see a progress spinner).
The Women's Session was published last week, and the other sessions were published Wednesday night. So, if you don't see the October 2017 conference yet, try force closing (swipe out of recent apps) and reopening the app, or, on Android, try pulling down on the main library.
Note also that if you have Limit Mobile Network Use on (Android) or Use Cellular Data for Content Updates off (iOS), the app won't check for new content unless you're connected to a Wi-Fi network.
