This is my first question on StackOverflow, so please bear with me if I fail to articulate my question.
I am working on an Android app that targets Android O, and I want the launcher to NOT show the icon adapted i.e. remove the white background. I tried to use adaptive icons and they work, but the problem is that they change the icon itself making it rouned, square, squircle and tear-shaped.
At first I thought it's out of my hands, but some other apps (facebook, whatsapp and snapchat for example) have their icons unchanged.
tl;dr: How can I force an icon to be used by the launcher on Android O?
The other apps you mention (Facebook, Whatsapp, and Snapchat) don't yet target Android O. Once they do, they'll also be forced to have an adaptive icon as well.
