I am working on AOSP build and trying to generate systrace output file in .html file for performance measurement through my test module and then process it into a .json file. But I am facing a problem while automating this process with python script since few days. I found developer guide in android community:



https://source.android.com/devices/tech/debug/systrace



https://developer.android.com/studio/command-line/systrace



Here what I am trying to do:




  1. A top level python script file to process arguments, let say A.py

  2. processing i/p args and call AOSP systrace.py file.
    sample cmd:



python systrace.py --app test_module_path -o output_file_name.html --atrace-categories=app,hal,sched,freq,idle




Observation:



If I invoke this script from my main script through subprocess.open(), then it is not creating .html file. On the contrary if I invoke it separately, it generates a .html file but I am suspecting if .html generated is proper as json file not able to be generates from out of it!



Query:




  1. Does anybody point if systrace.py doesn't create output file if test_module_path gtest fails some testcases.

  2. How to know if proper .html file is generated.
