WorkManager periodic request not runnning?

Question

I am trying to run an api call periodically every one hour. I know the minimum time interval for periodic request is 15 minutes i have definitely kept it more than that.

Below is my code to run periodic request

val data = Data.Builder().putString(
            "covid_country",
            viewModel?.getSavedCountry()
        ).build()

        val request =
        PeriodicWorkRequest.Builder(CovidWorker::class.java, 1, TimeUnit.HOURS)
            .setInputData(data)
            .setConstraints(
                Constraints.Builder()
                    .setRequiredNetworkType(NetworkType.CONNECTED)
                    .build()
            )
            .build()


        WorkManager.getInstance(this)
            .enqueueUniquePeriodicWork("simplified", ExistingPeriodicWorkPolicy.KEEP, request)

In the workmanager class's doWork method i am just calling the api and send local notification if successfully.

override fun doWork(): Result {
        val covidCountry = inputData.getString("covid_country")
        Log.i("savedd112", covidCountry)
        Coroutines.main {

            val response =
                CovidApi().getCovidCases("india")

            val count = response?.get(response.size - 1)?.Cases ?: 0
            Log.i("hereeached", "mark")
            displayNotification("Cases in india", "$count")


        }
        return Result.retry()
    }

But it is never runned. I dont see my local notification. I waited the whole day for this. There is no easy way to debug this so i decided to convert my periodic work request to one time work request and added a button in my UI and on the button on click listener i called the following code

WorkManager.getInstance(this).enqueue(request)

Now the api gets called correctly and the local notification is displayed when the api succeeds. I dont understand why my periodic request is not running

Answer 1

So i finally figured it out

Instead of using

ExistingPeriodicWorkPolicy.KEEP

use this

ExistingPeriodicWorkPolicy.REPLACE
