Triaged the crashes again. crash.20200109 is the only one that bothers
me. It will probably continue at a low incidence until I figure out
what's causing it.

2021/01/17 - confirmed this is still happening with version 26 of the
app, reported on Android 8.1 (SDK 27) and Android 10 (SDK 29).
https://stackoverflow.com/questions/51222082/why-do-i-get-remoteserviceexception-for-creating-updating-a-notification
suggests it has something to do with the Notification passed to
startForeground(), but their "workaround" was to only modify the
Notification from the Service thread, which we already do.
I could not reproduce it under the emulator with Android 8.1 and starting
the service is several different contexts, including using the START
broadcast after the app had been force stopped, or when the service had
started because the package had just been updated (UI not displayed yet).
I also tested launching the PendingIntent from those contexts.
Looking at ActivityThread.java that came with my SDK and it looks like
RemoteServiceException() is just called whenever handleMessage() is
passed a msg.what == SCHEDULE_CRASH, which is sent from
ApplicationThread.scheduleCrash(), which is called (indirectly) from:
ActivityStackSupervisor.PendingActivityLaunch.sendErrorResult()
... ultimately called when there's an exception during a
PendingIntent launch, with the string from that exception??
BroadcastQueue.performReceiveLocked() on a RemoteException with the
string "can't deliver broadcast"
ActivityManagerShellCommand.runCrash() with "shell-induced crash"
ServiceRecord.postNotification() with "Bad notification for startForeground:"
ActiveServices.serviceForegroundCrash() with
"Context.startForegroundService() did not then call
Service.startForeground():"
NativeCrashListener.NativeCrashReporter.run() but I'm not sure it
actually makes it into the same crashApplication() or not?
RuntimeInit.wtf() not sure where this error winds up either but
Most of those, I think, would be pretty good about putting a message
there so I'm not clear why no message is provided.
Googling some more:
https://github.com/commons-app/apps-android-commons/issues/1877
failed to set a NotificationChannel but I think I've already
crossed that bridge.
https://www.xspdf.com/resolution/50183960.html
the XML layout for their Notification specified a manual height for
the root element?? the outer element for mine is wrap_content, but
one of the contents is an ImageView with a manual size (60dp x
60dp) ?? (and many others at this URL) Could maybe be a problem
with the res/drawable for the notification icon?
Crashlytics would apparently provide more info -- I'm not clear why
Google's crash reporter isn't giving me the RemoteServiceException
message on its own though! But Crashlytics smells like bloatware to me
and from looking at the source (/usr/src/firebase-android-sdk), I didn't
immediately see how it could change the reporting of this sort of crash.

2021/01/17 - Looking at the play console today, this crash is not in the
last 60 days which is all it will show me. So I guess it's rare.

2021/01/17 - This has been reported from two different users, both on
OnePlus3 phone running Android 9. It was reported both with version 16
and 24 of SimpleSSHD. It seems to be from where SimpleSSHDService tries
to load simplesshd-jni, which is the core JNI for the whole thing and the
only one that is linked in the normal way. It is a normal processor
(snapdragon 820).
Since it's just the one kind of phone, I think I'm gonna ignore it. It's
probably some problem with how libc or JNI library is linked, but I can't
imagine what that problem is.
