New launcher icons for Android

Android has a new format to support different types of launcher icons (square, circle, ...). My app's icon at the moment is shown in very small inside a white circle.

I generated the new icons with the Android Image Asset Studio and placed them in the resources folder. However, the app icon is still shown in small inside a white circle or square.

My resources folder:

resources
- ios
- android
    - res
      - drawable
      - drawable-hdpi
      ....
      - mipmap
        - icon.png
      - mipmap-hdpi
        - icon.png
        - ic_launcher_foreground.png
        - ic_launcher_round.png
        - ic_launcher.png
      ......
      - values
      - xml
