ANDROID:

As Android is focusing on the efficient way of using the battery, the system deprives the resources of the app when the app is in the background(Dependent). It is better to use the work manager to handle your background tasks.

Take a look https://developer.android.com/topic/libraries/architecture/workmanager/basics.html

Sample code

class GetMessages(context: Context, params: WorkerParameters) : Worker(context, params) {

    override fun doWork(): Result {
        getAndSaveMessages()
        return Result.success()
    }

    private fun getAndSaveMessages() {
         // get messages here
    }
}

Put this code in a Singleton class to access it from anywhere Like JobManager

    object JobManager{
 private fun syncMessages(){
        val loadMessages = PeriodicWorkRequestBuilder<GetMessages>(5, TimeUnit.MINUTES)
        // Add tag to cancel the thread any time
        loadMessages.addTag("MESSAGES") 

        val myConstraints = Constraints.Builder()
                        .setRequiredNetworkType(NetworkType.CONNECTED)
                        // Many other constraints are available, see the
                        // Constraints.Builder reference
                        .build()
        // Add constraints
        loadMessages.setConstraints(myConstraints)

        WorkManager.getInstance().enqueue(loadMessages.buld())
    }

}

Now you can use JobManager.syncMessages() from anywhere
