Specification for size and fillet radius of android startup icon
The Android design interface of 720* 1280 px corresponds to a startup icon with a size of 96px*96px and a rounded corner approximately equal to 18px.
1080* 1920px Android interface design, the corresponding startup icon size is 144px 144px, and the rounded corner is about 25px.
======================================================
The application icon should be a transparent 32-bit PNG picture with an Alpha channel. Due to a large number of Android devices, application icons need to be designed in several different sizes, such as:
LDPI (low-density screen, 120 DPI), its icon size is 36 x 36 px.
Mdpi (medium density screen, 160 dpi) icon size is 48 x 48 px.
HDPI (high-density screen, 240 DPI), its icon size is 72 x 72 px.
Xhdpi (ultra-high-density screen, 320 dpi), its icon size is 96 x 96 px. It is suggested that a few pixels should be left around during the design process to make the designed icon visually consistent with other icons. For example,
The drawing area of 96 x 96 px icon can be set to 88 x 88 px, with four pixels around it for filling (no background color).
The drawing area of 72 x 72 px icon can be set to 68 x 68 px, leaving two pixels around for filling (no background color).
The size of the 48 x 48 px icon drawing area can be set to 46 x 46 px, with 1 pixel left around for filling (no background color).
The drawing area of 36 x 36 px icon can be set to 34 x 34 px, with 1 pixel left around for filling (no background color).
