I. Standard of subparagraph

When dpi>=480, use the xxhdpi tag resource, the ratio of 3 yoy

When dpi>=320, use the xhdpi tag resource, the ratio of 2 YoY

When dpi>=240, use the hdpi tag resource, the ratio of 1.5 yoy

When dpi>=160, use the MDPI tag resource, the ratio of 1 yoy

When dpi>=120, use the ldpi tag resource, the ratio of 0.75 yoy
