Hey I am working in WorkManager. My code is running in android 11 and below . I want to support WorkManager for sdk 31(android 12). I am reading doc and it confused for my scenario Backwards compatibility and foreground services. I am adding code please have a look and guide me is my code doing right?

implementation "androidx.work:work-runtime-ktx:2.7.1"

NotificationWorker.kt

class NotificationWorker(appContext: Context, workerParams: WorkerParameters) : Worker(appContext, workerParams),
    KoinComponent {

    private val notifications: Notifications by inject()

    override fun doWork(): Result {
        notifications.createNotification(NotificationType.REMINDER, null)
        TrackerHelper.setupNotificationWorker()
        return Result.success()
    }
}

TrackerHelper.kt

object TrackerHelper {

     fun setupNotificationWorker() {
           val delayDuration = getDelayMillis()
           val dailyWorkRequest = 
                OneTimeWorkRequestBuilder<NotificationWorker>()
                   .setInitialDelay(delayDuration, TimeUnit.MILLISECONDS)
                   .addTag(REMINDER_WORK_TAG)
                  .build()
          WorkManager.getInstance(Application.appContext).enqueue(dailyWorkRequest)
    }

    private fun getDelayMillis(): Long {
           val currentDate = Calendar.getInstance()
           val dueDate = getNotificationDueTime()
           if (dueDate.before(currentDate)) {
               dueDate.add(Calendar.HOUR_OF_DAY, 24)
           }
           return dueDate.timeInMillis - currentDate.timeInMillis
    }
}

The above is perfectly working in android 11 and below version. But It's not working in android 12. So I am reading in official doc Kotlin inside doWork() they are using setForeground() and in Java using setForegroundAsync(). So which is useful in my case. CoroutineWorker and what the use case of getForegroundInfo() this function and how to proper handle this not to throw error

I am totally confused what function need to be used in my case and please explain me which one is use when with example. Thanks in advance

I am getting this error in android 12
