PeriodicWorkRequest after device startup

[mZadorskii]

Task is never executed after device reboot. Did anyone try it? What I'm missing?

Android 8 on Pixel 2
PeriodicWorkRequest
RECEIVE_BOOT_COMPLETED in manifest.
android.arch.work:work-runtime + android.arch.work:work-firebase 1.0.0-alpha02

PeriodicWorkRequest.Builder periodicWorkBuilder= new PeriodicWorkRequest.Builder(WatchListWorker.class, 20, TimeUnit.MINUTES);
PeriodicWorkRequest periodicWork= periodicWorkBuilder.build();
WorkManager.getInstance().enqueue(periodicWork);

Correct me if I am wrong but shouldn't workmanger schedule the periodic task automatically after Boot Complete?

Observed the same on my side, the periodic task is not executed after the device reboots =(
@sabinbajracharya yes I have also read in multiple resources that WorkManager is supposed to continue working even after device reboot.

use receiver after boot completed and start the workmanager again there.

Thanks for reporting this.

Stackoverflow might be a better forum. This one is for issues with the codelabs.

I'm closing this issue because this forum is for issues with the codelab.

If you think that this is a problem of the WorkManager library, please open a bug on the WorkManager public issue tracker: https://issuetracker.google.com/issues/new?component=409906&template=1094197

Please reopen if you still think this is an issue with the codelab.

Update: I found out it wasn't an API issue but something that had to do with the device manufacturer. HiOS and XOS android flavours from Tecno and Infinix restrict the access to listening to the BOOT_COMPLETED broadcast and it affected the WorkManager too.

It seems that it's possible that the device manufacturer could be restricting Workers from being restarted after device reboot.

Edit:
Just confirmed that battery optimization could also be the culprit:

Tested on Pixel XL (Android 10), after turning off battery optimization for my app and restarting the device. My periodic Worker was executed as expected.

The Worker also kept working even when app was swiped off the recent apps drawer.
