Check the folder "res" in use in android app

Question

When you start an android application, the operating system detects the screen resolution and uses the graphics included in the folder mdpi, hdpi, xhdpi or xxhdpi.

My question is: is there any way to know which folder to use android?

for example, would be perfect if I could get a variable that indicates the value "mdpi" or "xxhdpi" ...

I searched but I always find ways to get the resolution, and I want to be sure which is the folder "res" that will use Android.

Thank you very much in advance

            switch (mContext.getResources().getDisplayMetrics().densityDpi) {
            case DisplayMetrics.DENSITY_LOW:
                return "ldpi";
            case DisplayMetrics.DENSITY_MEDIUM:
                return "mdpi";
            case DisplayMetrics.DENSITY_HIGH:
                return "hdpi";
            case DisplayMetrics.DENSITY_XHIGH:
                return "xhdpi";
            case DisplayMetrics.DENSITY_XXHIGH:
                return "xxhdpi";
            }

        } catch (Throwable e) {
        }
