New debugging tool in adb shell dumpsys gfxinfo
This tool lets you visualize the time it took, in ms, to: - Build display lists ("Draw" phase) - Process display lists ("Process" phase) - Swap GL buffers ("Execute" phase) To use this tool: - adb shell setprop hwui.profile true - adb shell dumpsys gfxinfo <process name> - Copy the profile data and paste it in a spreadsheet - Generate a graph (stacked graph) and enjoy Change-Id: I7840c0ea0f153550425aa798e3ada2f357688cf5
