Different icon dimensions

 name of icon is  ic_launcher.png

THere are individual icons for different resolutions in the res folder.

like:

midmap-hdpi\ic_launcher.png

midmap-mdpi\ic_launcher.png

midmap-xhdpi\ic_launcher.png

midmap-xxhdpi\ic_launcher.png

midmap-xxxhdpi\ic_launcher.png

And we need to specify in AndroidManifest.xml about icon.

Inside application tag add attribute,

android:icon="@mipmap/ic_launcher"

other than these, one in the main res folder itself with higher resolution to show in google playstore webpage - ic_launcher-web.png.

THis file is not part of app.

So, we can move it to a separate folder.

<root_folder>\art\
