  • I'm encountering the same issue. Mac OSX 10.14. tianrui yang answer did not resolve issue. Further experimentation showed issue only occurs on older api versions (<=21) – Jeremy Dec 23 '18 at 23:37
  • I am getting the same problem on my API level 22 device. I see a couple messages in logcat that say `BnListenService::onTransact received unrecognized msg 1599295570` from mediaserver process. Systrace however is working on my API level 26 device. – satur9nine Mar 29 '19 at 23:30

It might be used incorrectly parameters in systrace. The correct command is here, please try it. 

python ./systrace.py -t 5 -o ./trace.html gfx input view webview wm am sm audio video camera hal app res dalvik rs bionic power sched irq freq idle disk mmc load sync workq memreclaim regulators

Using systrace of catapult project, not in Android SDK worked for me.

$ git clone https://github.com/catapult-project/catapult.git
$ ./catapult/systrace/bin/systrace
