NPE when startForeground

Question

NPE reported in crashlytics only for Android O and above. I just startForegroundService and the service startForground in onCreate method and the NPE happened.

In crashlytics it happened when startForeground(NOTIFICATION_ID_TOOLBAR, mNotification);

@Override
public void onCreate() {
    super.onCreate();
    buildNotification();
    startForeground(NOTIFICATION_ID_TOOLBAR, mNotification);
}

Unable to create service ToolbarService: java.lang.NullPointerException: Attempt to read from field 'int com.android.server.am.UidRecord.curProcState' on a null object reference

Have you set up notification channels by the time of calling of startForeground ? — Pratzz, Jan 07 '20 at 13:33
Would love to hear if you ever made any progress on this. Am facing the same issue.. In my case it's when the app is re-installed. — Jeffrey Blattman, Feb 25 '20 at 00:40
I am also facing the same issue, @user3162215 were you able to resolve it ? — Nitin Mesta, Apr 10 '20 at 13:01
I only see SM-T595 devices with Android 9 affected. Any others? — Alexey Ozerov, Jun 07 '20 at 03:43
I also acknowledge this only under Android 9, but on multiple Samsung devices — Benoit, Jan 26 '21 at 01:34
@AlexeyOzerov I got this issue reported on a Zebra Technologies TC77 device running Android 8.1. so it's not specific to Samsung — Adam Burley, Jan 25 '22 at 17:41

Probably mNotification value is null. You need to analyze your code to figure out why and when. This code snippet is to short to perform any analysis.

Nope, mNotification is not null when buildNotification(); is called – user3162215 Jun 12 '19 at 02:06
So if `NOTIFICATION_ID_TOOLBAR` is not `null` too, then there will be `null` somewhere inside `startForeground(...)` method, but I have no idea where. It needs to be debugged. – Piotr Wittchen Jun 12 '19 at 08:24
