Using WorkManager on Android 12

WorkManager has two new releases for your consideration: 2.6 and 2.7.
Version 2.6 has just reached stable and 2.7 is now considered beta and will be stabilized soon.

WorkManager 2.6 is a fully packed feature release. Instead of WorkManager’s own initialization provider it uses App Startup. This means you’ll have to update the way you removed the default content provider for WorkManager. Here’s the new code:

<provider
    android:name="androidx.startup.InitializationProvider"
    android:authorities=\"${applicationId}.androidx-startup"
    android:exported="false"
    tools:node=\"merge">
    <!-- If you are using androidx.startup to initialize other components -->
    <meta-data
        android:name="androidx.work.WorkManagerInitializer"
        android:value="androidx.startup"
        tools:node="remove" />
</provider><!-- If you want to disable android.startup completely. -->|<provider
    android:name="androidx.startup.InitializationProvider"
    android:authorities="${applicationId}.androidx-startup"
    tools:node="remove" />

WorkManager now also provides improved multi-process support using the work-multiprocess artifact.

WorkManager 2.7 & Android 12

However, WorkManager 2.6 is missing one key piece for apps targeting Android 12 (API level 31). Starting in Android 12, foreground service launch restrictions were introduced. These restrictions can leave your app in a state where calling setForeground may cause an exception.

With WorkManager 2.7 expedited jobs were introduced. Expedited jobs allow apps to execute short and high-priority tasks while giving the system better control over access to resources. Expedited jobs are the recommended way to start a task from the background.

We introduced the setExpedited API that is designed to cover most use cases. There are some exceptions for when an app is not subject to foreground service restrictions. The most obvious is, when your app is visible to the user. All other cases are documented here.

To see WorkManager’s setExpedited() API in action, check out our official WorkManager Sample.

You can see a detailed list of changes and improvements made in each WorkManager release in the official release notes, along with specific release notes for Workmanager 2.6 and WorkManager 2.7.
