PeriodicWorkRequest on Android Oreo device does not repeat as scheduled

[borysboyko]

Problem: worker scheduled with WorkManager.enqueueUniquePeriodicWork() runs once and never again.

My setup:

private static final Constraints NETWORK_WORK_CONSTRAINTS = new Constraints.Builder()
    .setRequiredNetworkType
        (NetworkType.CONNECTED).setRequiresBatteryNotLow(true).build();

WorkManager workManager = WorkManager.getInstance();
PeriodicWorkRequest getSettingsWork = new PeriodicWorkRequest.Builder(GetSettingsWorker
        .class,
    PeriodicWorkRequest.MIN_PERIODIC_FLEX_MILLIS,
    TimeUnit.MILLISECONDS).addTag(GetSettingsWorker.TAG)
        .setConstraints(NETWORK_WORK_CONSTRAINTS).build();
    workManager.enqueueUniquePeriodicWork(GetSettingsWorker.TAG, ExistingPeriodicWorkPolicy.KEEP,
        getSettingsWork);

Logs show:

08-07 21:05:52.472 2606-2679/com.my.app I/WorkerWrapper: Worker result SUCCESS for Work [ id=6f2c3d84-9c0b-4a59-a5e5-fb3a82083bb7, tags={ com.my.app.GetSettingsWorker } ]

What can I try?

Closing - meant to post this in issue tracker for the WorkManager library itself.

@borysboyko did you find the issue tracker? :)

@borysboyko I know this is closed but I want to provide a possible solution that affected me. I received the Worker result SUCCESS log and then it would not repeat. If you are testing on a hardware device make sure OEM or third party "protection" apps are not preventing the job.

On my Asus phone is an app called Auto-start Manager that prevents apps from staying in memory in order to free up resources. It could be called something else on another device but you get the idea. Allow it through the app and I get successful indefinite repeating jobs. Hope this helps someone.
