Working with WorkManager

This talk is about opportunistic guaranteed deferred background execution on Android. I'm not kidding. This is what WorkManager handles for us. You'll get a grasp on the basic concepts of WorkManager and by the time you're done with the slides, you'll be able to start Working with WorkManager!

Presented at the January 2020 installment of the Android Budapest meetup at AutSoft Ltd.

The talk was recorded and it's available on the Android Budapest YT channel:
