Android status bar expects icons of size 25x25dp while guidelines recommend 32x32dp. Who is wrong?

Question

According to android icon design guidelines (here, see table #1), developer needs to provide status bar icons of next sizes:

Status Bar  24 x 24 px (LDPI)  3         


        

Answer 1

Actually it's

• 18px(ldpi)
• 24px(mdpi)
• 36px(hdpi)
• 48px(xhdpi)
• 72px(xxhdpi)
• 96px(xxxhdpi)

it's 24dp size with a 2dp padding , means 20dp content

px = dp * (dpi/160)
