Which device are you running on?

Could you try running adb shell setprop persist.traced.enable 1 and then retrying?

from perfetto.

@wingyippp , what happens if you do adb shell rm /data/misc/perfetto-traces/profile-shell
@segfaulthunter maybe the script should use unique file names (and delete them after pull)?

adb shell rm /data/misc/perfetto-traces/profile-shell
rm: /data/misc/perfetto-traces/profile-shell: No such file or directory

Then run the cmd again "tools/heap_profile [process_name]", I got the same error show above.

P.S. My device is Android 10.0

These can be viewed using pprof. Googlers: head to pprof/ and upload them.

It's OK now. Thank you!
