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 (
// 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

Thanks you so much for the speedy fixed!
May I know when will it be ready for production? As, currently, this IllegalStateException is impacting our users.

Hello, please look for this later in the week. If you want to work around this bug specifically and don't need on-demand initialization, you can use the old (deprecated) WorkManager.getInstance() method for now.
yb...@google.com
Hello. Thanks for respond. I surely will keep a pair of eye on the next release :)
Yes. We don't need on-demand initialization. May I know how does using old (deprecated) WorkManager.getInstance() in our app code, able to bypass this problem? Isn't the crash is origin from library internal SystemJobService?
We once thinking to bypass this problem, by switching back to Version 2.0.1 (The version just before WorkManager.getInstance(Context) is introduced). However, we notice Room version is being changed in between. Downgrading WorkManager version, might cause additional SQLite problem.

Sorry, you are correct that moving to the deprecated method will not help you here. I would advise waiting for the release later this week. And thank you very much for finding this bug and doing the research to find the underlying issue.
I am curious: do you actually have reports of this bug on Android 9? It should've been fixed in the platform layer at that point. If possible, can you share any Android 9 specific logs/bugreports/stacktraces with device models?

OK. Finger crossed users will not leave our app. I will follow the Green Dinosaur in Twitter, to wait for his announcement.
Based on your code comment, I thought this problem shouldn't occur in new Android but it happens some how. This is the log
Asus ZenFone 5 (ZE620KL) (ASUS_X00QD), Android 9 (Happen 2 times)
Asus ZenFone 5Z (ZS620KL/ZS621KL) (ASUS_Z01R_1), Android 9 (Happen 1 time)
3 incidents are having same log trace as below

I attach the screenshot of Google Play Console as well. (I expect the stack trace should print programmer's message side-by-side with IllegalStateException. But it doesn't)
Feel free to let me know if you need any information from my side. Happy to help.

Hello, wondering whether the fix will be released in another one, or two days. As, users start to complain and leaving our app, due to increased crash rate :(
Thanks.
Thanks.
