Terminal spam with `F/android.hardware.atrace@1.0-service(25128): Check failed: stat(tracefs_event_root_.c_str(), &st) == 0 tracefs` #94652

nikhilbadyal · 2021-12-04T07:12:31Z

Whenever i try to run flutter application. It spams the whole terminal with these lines.
and it only happens when i use WIRELESS DEBUGGING.
Any fix or solution ?

@nikhilbadyal I can't really reproduce the issue.

and it only happens when i use WIRELESS DEBUGGING.

Is this using adb via the command line? Are you seeing these logs when running via android studio or from the command prompt?

flutter doctor -v

It shouldn't matter ig. But as you asked it happens everytime. Whether i run from AS by pressing the debug icon or using simple windows cmd

The command i use to connect my device is

adb connect myIPAddress

Log with plain old windows CMD

Thanks for the info

In my case, this problem arises even when debugging via USB.
(It started when connected to wireless debugging though);

I have tested my other devices running Android 7.1.1 and 10. they both work fine.
I think the problem is that my phone's custom rom/kernel doesn't have the file at /sys/kernel/tracing or /sys/kernel/debug/tracing or it's not mounted, i don't know why it's not there

whyred:/ $ ls /sys/kernel/tracing
ls: /sys/kernel/tracing: No such file or directory
1|whyred:/ $ ls /sys/kernel/debug/tracing
