Android 8.0 (API level 26) introduced adaptive app icons, which are made out of background and foreground layer. Apps that have minSDK = 26 don't have to specify "flat" PNG icons. However, App Distribution doesn't support adaptive app icons, and as a result weird icon with cropped app name is displayed in the App Tester app. App Distribution should support adaptive app icons by parsing icon XML, obtaining foreground and background assets, and based on this render the icon.
