Need to add HWUI tag here – N0dGrand87 Oct 27 '17 at 15:39 — N0dGrand87, Oct 27 '17 at 15:39

In the AOSP exists several approaches how to render UI:

based on CPU library such as SKIA
based on HW accelerated library - such as HWUI

For the above log, output means - your Activity does not use accelerated HWUI - there is no allocated HardwareRenderer implementation to your Activity's Views. The dumpGfxInfo() API implementation has nothing to output here - see the sources

Here is relevant question How to enable skia with GPU backend on JB - to enable HWUI utilization
