   > The question is, where should I have the res folder?
   
   in the context of `<icon src="...">` the path is relative to the cordova 
project.
   
   A standard cordova project folder will look like...
   
   ```
   / - root
       /config.xml
       /www
       /platforms
      ...
   ```
   
   So you can create a `res` folder and organise it that way that it makes 
sense for you.. e.g. `/res/icons/android/...` and have the icon configured as: 
`<icon src="res/icons/android/..." />`
   
   > Also not sure if one png file would be enough?
   
   You're also correct... a single resource isn't enough for Android. While 
Android API 21 supports vector icons, which Cordova has support for... Cordova 
still assumes that mipmap (rasterized PNGs) are used, in which case you need to 
provide a different resolution version for the different density levels, which 
are as follows:
   
   |density|resolution|
   |---|---|
   |mdpi|48x48|
   |hdpi|72x72|
   |xhdpi|96x96|
   |xxhdpi|144x144|
   |xxxhdpi|196x196|
   
   There is also a `ldpi` that uses 36x36 image but no device that cordova 
supports today uses a low density, so it can be omitted. You specify each icon 
using the `"density"` attribute: `<icon src="..." density="mdpi" />`
   
   At minimum this is what you'll need. But there are [optional 
settings](https://cordova.apache.org/docs/en/12.x/config_ref/images.html#adaptive-icons)
 to support adaptive icons for API 26+ devices, as well as monochrome icons for 
API 33+ devices.
   
   Icons can be replaced with an [Android 
Vector](https://developer.android.com/develop/ui/views/graphics/vector-drawable-resources)
 resources instead of using PNGs but I believe Cordova still expects you to 
specify each density.
