WorkManager is the recommended solution for persistent work. Work is persistent when it remains scheduled through app restarts and system reboots. Because most background processing is best accomplished through persistent work, WorkManager is the primary recommended API for background processing. Read more in official docs

3 Steps to run periodic tasks in the background even the app is closed:

#1 Init Jetpack WorkManager

WorkManager.getInstance(applicationContext)

#2 Setup Worker

class PriceAlerterWorker(
    appContext: Context,
    params: WorkerParameters,
    private val interactor: PriceAlerterInteractor
) : RxWorker(appContext, params) {

    override fun createWork(): Single<Result> =
        interactor
            .createDemoAlert()
            .map { result ->
                when (result) {
                    is RxResult.Success -> {
                        //Do something on success
                        Result.success()
                    }
                    is RxResult.Failure -> {
                        //Do something on fail
                        Result.retry()
                    }
                }
            }
}

#3 Build request and run work

        PeriodicWorkRequestBuilder<PriceAlerterWorker>(15, TimeUnit.MINUTES)
            .setConstraints(
                Constraints.Builder()
                    .setRequiresBatteryNotLow(true)
                    .build()
            )
            .addTag(WORKER_PRICE_ALERT_TAG)
            .build()
            .let { request ->
                workManager.runUniqueWork(
                    request,
                    "${WORKER_PRICE_ALERT_TAG}_periodic"
                )
            }

More about WorkManager:

Notes:

  • The minimal interval for periodic tasks is 15 minutes, even if you set 1 min.
  • Retry with Backoff policy supports the minimum 10 sec and the maximum 5 hours interval (30 sec by default).
