I'm a little confused.
I've created a game using the Unreal Engine and I plan to publish in about a month. I knew my app needed an icon, but I was on Google's developer site yesterday and I saw a whole BUNCH of guidelines for icons, and there are several kinds. They say something about placing different versions of the icon in my 'resources' directory, but I didn't develop in Android Studio. I thought I would just be making one 512x512 icon, and uploading my APK (plus the other info).
Could someone who has used Unreal and published to the Play Store please help me :) Do I really have to make so many icons?
