How does Frame per second of the unity3d game engine on android mobiles captured using gamebench
Tried using the gfxinfo over adb commands, doesnt help much ?
Need more help how to calculate the FPS of unity3d games on Android ?
回答1:
My guess is that it uses these commands [programmatically]:
(1) adb shell dumpsys SurfaceFlinger --latency-clear
(2) adb shell dumpsys SurfaceFlinger --latency <window name>
e.g.,
adb shell dumpsys SurfaceFlinger --latency com.android.settings/com.android.settings.SubSettings
RefreshPeriod <-- Time in nano seconds
desiredPresentTime actualPresentTime frameReadyTime <-- Time in nano seconds
desiredPresentTime actualPresentTime frameReadyTime
desiredPresentTime actualPresentTime frameReadyTime
...
On how to interpret the results, see https://chromium.googlesource.com/chromium/src/build/+/fefabac95d6aee4d941111e67f606dc50dfe9dd1/android/pylib/perf/surface_stats_collector.py#215 and https://android.googlesource.com/platform/frameworks/native/+/86efcc0/services/surfaceflinger/FrameTracker.cpp#217
