WorkManager not repeating the PeriodicWorkRequest

Update your WorkManager version to 1.0.0-alpha04. You can check release notes here

Also, refer to this PeriodicWorkRequest GitHub demo and update TimeUnit as per your requirement in DayIncrementViewModel.java. It will work as per your need.

WorkManager is still in alpha mode so it will work completely for all devices once they release the final version.

according to the documentation:

 /**
 * The minimum interval duration for {@link PeriodicWorkRequest} (in milliseconds).
 */
public static final long MIN_PERIODIC_INTERVAL_MILLIS = 15 * 60 * 1000L; // 15 minutes.
/**
 * The minimum flex duration for {@link PeriodicWorkRequest} (in milliseconds).
 */
public static final long MIN_PERIODIC_FLEX_MILLIS = 5 * 60 * 1000L; // 5 minutes.

if you are setting this two value less than min specified, then you have to wait approx 20 min to see the log/output

If you use PeriodicWorkRequest with interval less than 15 min, you should return Result.retry(), not success or failure.
