for the average user, the main screen icon/launcher icon (the general abbreviation app icon) is the first impression that the app gives them. With the constant evolution of mobile phone and tablet resolution, it becomes even more important to make the main screen icon of your application clearer and more qualitative. To do this , you need to make sure you do the XHDPI (320dpi) and xxhdpi (480DPI) Resolution versions of the icons placed in the app.

when you plan to make your own home screen icon, be sure to follow some of the same important guidelines as in addition to the existing Home screen icon code :

The launcher icon is a 48dp square size and needs to provide MDPI, HDPI, XHDPI, xxhdpi resolution sizes-at least XHDPI and xxhdpi.
the 512px size of the Play Store display icon should be the same as the app icon, except for some minor details.
The launcher icon needs to be designed to be purely Android-style. As mentioned in "pure Android" , avoid mimicking the visuals and styles of other platforms (such as rounded rectangles and drop highlights).
The launcher icon should be stereoscopic, front view, and tilt-down at a certain angle, so that the user can feel the presence of "depth/thickness".

The main screen icon should also have a distinctive silhouette, which also means you need to avoid simple squares or circles to select unique shapes. (Note: four times and stroking waves are lying on the gun ...) And Google's home Google +, Search and other applications have not been able to do this?
At the macro level, the main screen icon should be simple and concise, but at the micro level, still can not abandon rich details (for example: fine edge effect and reasonable gradient, texture).
The main screen icon should use a light-weight background protection, such as fine, subtle projections, but not too dark or distracting.
The main screen icon should contain a 0DP to 3DP margin, using different margins to achieve optical alignment and the normalization of the visual weight of the icons.

It is important to note that tablets and other large-screen devices require an icon resolution greater than its own resolution, so you need to provide as much of the high-resolution version of the app icon as possible. For example, for a tablet with a XHDPI screen, the main screen icon needs to reach xxhdpi Level of resolution.
