In SystemJobService, it can expect null, and able to tolerance null from WorkManagerImpl.getInstance, due to auto-backup reason.
@Override
public void onCreate() {
super.onCreate();
mWorkManagerImpl = WorkManagerImpl.getInstance(getApplicationContext());
if (mWorkManagerImpl == null) {
// This can occur if...
// 1. The app is performing an auto-backup. Prior to O, JobScheduler could erroneously
// try to send commands to JobService in this state ( b/32180780 ). Since neither
// Application#onCreate nor ContentProviders have run, WorkManager won't be
// initialized. In this case, we should ignore all JobScheduler commands and tell it
// to retry.
But, current WorkManagerImpl.getInstance(Context context) implementation is that, it will never return null but throw IllegalStateException.
Isn't there's conflict among these 2 SystemJobService.onCreate logic, and WorkManagerImpl.getInstance logic?

Fix for JobScheduler calls when backup is in progress.
The original fix (ag/Ia1604b7c4b98f6b31869e1161a0c1efce7fe46f2) relied
on a null-check, but the new version of WorkManager.getInstance(Context)
with the Context param doesn't return null; it throws an Exception. This
CL updates the three places where we explicitly check for the return value
internally:
1. SystemJobService (the main place where this would manifest)
2. RescheduleReceiver
3. WorkManagerTestInitHelper (for consistency)
Fixes: 135858602
Test: Ran existing tests

Description
Component used: Workmanager Version used: 2.4.0 Devices/Android versions reproduced on: Multiple devices, Nokia 8.1 Android 10, Huawei P30 lite (Android 9), Xaomi Redmi 9 (Android 10)
In our app we run 3 jobs through
WorkManager
and we are observing that sometimes a periodic job that runs the most often is sometimes not added in the system job scheduler after it ran. This can be verified by looking atadb shell dumpsys jobscheduler
. The devices in question have been left alone for a while over a couple of hours.WorkManager.initialize()
will also not restore these missing jobs.One reason for this could be that the system job scheduler implementation isn't checking the return code from
JobScheduler.schedule()
, especially since this issue doesn't happen every single time the job has run.Logs from the app indicate
WorkManager
scheduling job id 7, but this id is not showing up for thenl.rijksoverheid.en
package. Only id 3 & 4, that have been scheduled at the same time as the initial periodic job, are shown in the output:Here's the WorkManager log output after the job has been run:
