Which worker need to be use when migrating firebase-job-dispatcher to workmanager?

Question

To use WorkManager you have to subclass one of the available Worker classes:

• ListenableWorker
• Worker
• RxWorker
• CoroutineWorker

I want to run the job every 2 hours. Some of the answers mentioned should be use Listenable Worker. I am confusing this which one suits to this scenario. Please help me on this.

Answer 1

WorkManager has some extensive documentation on how to use it that also includes a migration guide covering the move from Firebase JobDispatcher.

In the documentation you can find a section that explain the different threading behaviour of the different Worker classes.

In your particular case, it really depends if what you want to execute periodically is synchronous or not.

• If what you want to run is synchronous: use a Worker
• If what you want to run asynchround: use a CoroutineWorker if you're using Kotlin, otherwise you've to use a ListenableWorker.
