Getting ready

In this recipe, since we will be looking at examples, you can follow along by reading and seeing if this applies to you.

How to do it…

Let’s learn how threading works in WorkManager:

1. In order to configure WorkManager manually, you will need to specify your executor. This can be done by calling WorkManager.initialize(), then passing the context, and the configuration builder...
