It is a thing of a concrete developer if he place more icons in different dimensions or not. In iOS developing, there must be more icons, but in Android, there can be only one icon in "drawable" folder. My experiences with use of only one 128×128 px icon in Android is positive, because on all testing devices icon looks great. When developer will be unhappy with system resized icon, he can put more icons with different resolutions.
I'm using CLI and I'm using only one icon. And is annoying Cordova CLI everytime copy icon also on drawable-hdpi, drawable-ldpi folders and on and on instead of only into drawable folder. But You don't realize, that this is double bug, because this icon are in specific drawable folders, but in bad resolution... So benefits of this are missing. Behaviour to be expected of (Android) CLI: * icon with density not specified => copy this icon into drawable folder * icon with density specified => copy into intended drawable folder (drawable-density) Current behaviour of (Android) CLI: * icon with density not specified => copied this icon (and in addition all icon in the same resolution) into all of drawable folders except drawable folder... * icon with density specified => i don't tested this behaviour, I don't like byrocracy, so I don't use this scenario (on Android development naturally), but i think this scenario is functional Nice day, Jan Velecký. " I disagree about Android doing a good job. We just don't notice it because we happen to have stupidly high quality template icons and we mostly test on hdpi and xhdpi devices. I'm sure if I ran this on an mdpi or ldpi device, the icon would be all distorted. "
