The launcher icon is a graphic that visually identifies the app to the user. On an Android device it's seen in the app list, and also can be placed on the launch screen. You need to supply multiple versions of the graphic in different sizes and pixel densities, but Android Studio will do the replicating and resizing of your graphic for you. Just start with a rectangular graphic that's at least 512x512. It should have some transparency built in to give it a recognizable profile.
