I fixed the above warning by replacing the app icon (Playstore Icon) from the new Google Play Console>Main Store Listing>App icon based on the new guidelines introduced by Google https://developer.android.com/google-play/resources/icon-design-specifications
To export the new Play Store Icon, i followed the below link https://developer.android.com/studio/write/image-asset-studio
(Image Asset Studio places the icons in the proper locations in the res/mipmap-density/ directories. It also creates a 512 x 512 pixel image that’s appropriate for the Google Play store.)
-
From Android Studio right click on the folder res>New>Image Asset
-
Generate the New Play Store Icon from the “Configure Image Asset” popup by selecting the Icon Type as Launcher Icons (Adaptive and Legacy) if your app supports Android 8.0 (https://developer.android.com/studio/write/image-asset-studio#create-adaptive) or select Launcher Icons (Legacy Only) if your app supports versions no higher than Android 7.1 (https://developer.android.com/studio/write/image-asset-studio#create-legacy)
-
Click Next and a new Popup appears to Confirm where to export the new Play Store icon (ic_launcher-playstore.png) (512×512).
-
Click Finish and upload the new exported Play Store icon in Google Play Console>Main Store Listing>App Icon and the warning now is gone.
