WorkManger works on Oreo but not Lollipop

问题:

WorkManager states that it works on OSes before JobScheduler and the like, yet it doesn't seem to work on API levels that use AlarmManager. I have a PeriodicWorkRequest which runs in intervals just fine on Oreo, but on Lollipop, it only runs the first time.

The code in question (PeriodicWorker.class is my own class of course):

WorkManager
                    .getInstance()
                    .enqueue(
                            new PeriodicWorkRequest.Builder(
                                    PeriodicWorker.class,
                                    PeriodicWorkRequest.MIN_PERIODIC_INTERVAL_MILLIS,
                                    TimeUnit.MILLISECONDS
                            )
                                    .setConstraints(
                                            new Constraints.Builder()
                                                    .setRequiredNetworkType(NetworkType.CONNECTED)
                                                    .build()
                                    )
                                    .build()
                    );

My WorkManager dependency is android.arch.work:work-runtime:1.0.0-alpha03.

Lollipop's functionality has been fixed in the newer version: android.arch.work:work-runtime:1.0.0-alpha04.
