raise ValueError('Invalid trace result format for HTML output')
ValueError: Invalid trace result format for HTML output
and the html that I get is empty.
the command I use is:
C:\Python27\python2.exe .\systrace.py --time=5 -o trace.html sched gfx view -a com.ir.tccim
os: windows 10 64 bit
usb debugging is enabled
debugging on device: galaxy j7 pro
just found out there is
System Tracing
app on android pie and higher, it will create a file that can be used by systrace to visualize the results :| – Ali Kazemkhanloo – 2019-07-26T16:08:49.577
