In Android Studio message "Paint.setShadowLayer.. graphics not accurate.." without this code

Question

I get this message in android studio xml preview: "The graphics preview in the layout editor may not be accurate: -Paint.setShadow is not supported." Without having this line of code at all in my project. Also I tried to run "Edit-Find-Find in Path" and didn't find this line of code at all in all my project, so why do I get this message?

I read this question, but don't think its the right answer cause this message start to appear after I tried few lines of code containing shadow values, but remain also after deleting those lines.

Answer 1

don't worry, it is saying that, preview of code will not as same as output, sometimes Invalid cache/restart will work, or change API level in combo box at the top of graphical preview.

Answer 2

Its showing this because of custom graphics. Hopefully the will have these views in next android studio update

Answer 3

The reason for warning is because you are using some of the material design elements (like floating action button) this warning can be removed by using Cordinate layout with these element
