Python script for making graphics performance charts for an Android app. To use, enable "Profile GPU rendering" from Developer Options (this is "Profile HWUI Rendering" on some devices), and restart the app you want to measure. Requires the matplotlib python library. Internally, uses dumpsys for gfxinfo and display via ADB.

Usage:

generate_frametime_graphs.py [-h] package [seconds] [title] [device]

Example:

python generate_frametime_graphs.py com.google.android.deskclock 5 example_graph 078f1fe513d

Output:

Median: 5.0ms 
Average: 5.0ms 
Device framerate: 60.0 
Estimated dropped frames: 4
