Android Icon Size

The application icon (icon) should be an Alpha channel transparent 32-bit PNG image. Due to the large number of Android devices, an application icon needs to be designed in several different sizes, such as:

LDPI (Low Density screen,120 DPI) with an icon size of X-px. MDPI (Medium Density screen, DPI) with an icon size of x px. HDPI (High Density-screen, + DPI) with an icon size of X-px. XHDPI (extra-high density screen, at + DPI), with an icon size of X-px. It is recommended that in the design process, a few pixels around the space to make the design of the icon and other icons in the visual consistency, for example, the nine X px icon can be set to the size of the drawing area of X-px, surrounded by 4 pixels to fill (no background). The X-px icon allows the paint area to be set to a size of 2 pixels, which is used for filling (no background). The X PX icon allows the drawing area to be set to a total of 1 pixels (without background) for the size of the range x px. The X-px icon allows the drawing area to be set to the X-px and 1 pixels around it for filling (no background).
