How can I run systrace to show its html output? After watching the Google I/O 2012 talk "For Butter or Worse" I am having trouble getting systrace to work on Windows 7 using the emulator running Jelly Bean 4.1.

I did the following:

  1. Installed Python 2.7, and added the install folder to my PATH
  2. Ran the following: C:\android-sdk\platform-tools\systrace>python systrace.py (with older SDKs: C:\android-sdk\tools\systrace>python systrace.py)

But I get the following error in cmd:

Traceback (most recent call last):
  File "systrace.py", line 212, in <module>
    main()
  File "systrace.py", line 124, in main
    ready = select.select([adb.stdout, adb.stderr], [], [adb.stdout, adb.stderr])
select.error: (10093, 'Either the application has not called WSAStartup, or WSAStartup failed')

Note:

  • I have enabled traces in the emulator: Settings > Developer Options > Enable traces
  • I have also tried with Python 3.2

The systrace python script uses the select() system call, and that doesn't work on Windows. The latest preview (ADT21 rc9) of the Android SDK tools include support for collecting system trace from within the monitor tool.

Launch monitor as:

./tools/monitor &

Click on a device, and at the top right of the device panel, you should have an toolbar itemn that allows you to collect system trace.
