> Interesting - while i'm not disagreeing with you, i've not heard that one before! that did cross my mind as a possible reason to it not working. Would also explain why my 'new' work phone (oreo/8) doesn't show the expected cpu performance when my old rooted oreo phone did.
Search for Android and /proc/stat.
> 'top' via adb did show the cpu usage (as you say, system apps work). maybe an inefficient way from the current method but couldn't a workaround be put in place to awk top? I'm certainly no software dev so don't know what the current method is or do's/don'ts for such features. I'd assume relatively performance heavy if it's calling top every n/secs.
I don't know how, or even if, spawning other programs works in
Android. I'm not optimistic it would work, though, as the problem is
not being able to open /proc/stat and other /proc files.
If somebody is really ambitious, I'd suggest writing a small, system
app which runs in the background and serves the CPU usage via a
socket. MythTV could then read from that app.
