According to Android Studio: "libpng warning: iCCP: Not recognizing known sRGB profile that has been edited", here's an answer:
It's just a warning, which libpng started issuing at version 1.6.0, so you can ignore it.
To get rid of the warning, you need to fix the PNG file that's named in the warning. You can use any one of a number of PNG image editors (ImageMagick, GraphicsMagick, etc.) to remove the offending iCCP chunk. Or you can downgrade your libpng to version 1.5.x.
See the similar question libpng warning: iCCP: known incorrect sRGB profile
You can use ImageOptim with those listed image files to get rid of that warning and remove: junk metadata and unnecessary color profiles.
Hope it help
