Ionic resource : icons

I generated icons via “ionic resource”. All icons are placed into the ./resources/android/icons/ => ok.

However, when I build my app via “ionic build”, the newly generated icons are NOT transfered into the platforms-directory.
Even when I remove the platform, it doesn’t help.

I keep on getting the “phonegap icon”.

What should I do to make my custom icon as the app-icon ?

I solved the problem by updating cordova-android to 6.1.0
