Android Periodic Work Request Start and Stop when the app is starting and closing

Question

When my app is starting, I created a periodic work request using WorkManager to fetch the data from the server and its working fine. My problem is, I want to cancel the work request when my app is closing.

How to cancel the work request when my app is closing or how to detect the app is closing?

I would appreciate any suggestions.

Answer 1

As mentioned in the Android Documentation.

In Kotlin

WorkManager.cancelWorkById(workRequest.id)

In Java

WorkManager.cancelWorkById(workRequest.getId());

You can also cancel WorkRequests by tag using WorkManager.cancelAllWorkByTag(String). Note that this method cancels all work with this tag. Additionally, you can cancel all work with a unique name using WorkManager.cancelUniqueWork(String).

EDIT

To check help in app closing events, check the ProcessLifecycleOwner.
