Android app icon size _android

In the Android program, the icons are set in the drawable, but the results are not shown in Millet 2, but they appear normal in my own HTC and emulator. It was later found that the DPI of millet was not the same.

It was later discovered that Android loaded a series of icons to accommodate different resolutions and DPI.

ldpi (Low density screen,120 DPI) with an icon size of X-px.

MDPI (Medium density screen, 160 DPI) with an icon size of X-px.

HDPI (High density screen, at the same size as the DPI), with an icon of X-px.

XHDPI (extra-high density screen, the image DPI) with an icon size of x px.

XXHDPI (xx-high density screen, and the DPI), whose icon size is 144 x 144 px.

If you set the icon, the Phone desktop icon does not update, you can restart the phone to try.

Some suggestions:

In the design process, several pixel points are left around to make the design icons visually consistent with other icons, such as:

x PX icon can draw area can be set to the size of the X-px, surrounded by 4 pixels to fill (no background).

The X-px icon can be drawn in the area size can be set to the X-px, around 2 pixels left to fill (no background).

The PX icon can be drawn in the area size can be set to X-px, around 1 pixels left to fill (no background).

x px icon can be drawn area size can be set to x px, surrounded by 1 pixels left for filling (no background).
