XXX - figure out what pie does to the boot event receiver
Testing with pie, I am able to reproduce the problem with start-on-boot.
Here's some excerpts from logcat:

So it looks like a pretty intentional rule that you can't start a service
from a boot receiver??
And I have the same problem on my Z2 Force (Oreo 8.0) now that I've
updated the SDK.
This guy says it will allow you to startForegroundService(), so that's
what I'll try...
https://stackoverflow.com/questions/49572570/android-start-a-service-on-boot-not-working
Which seems to work! So there is a need for some sort of dance in the
Settings screen to force it to enable foreground services if
start-on-boot is selected, and then we'll be golden.
XXX - some sort of failsafe so start-on-boot && >= OREO implies foreground
XXX - upgrade to newest dropbear
XXX - test with Android 16, and on my Moto X, and emulated 26, and emulated 28.
