title: App icon size on Android 8.0 if targetSdkVersion >= 26
body: <p>My app has a square icon. When <code>targetSdkVersion</code> &lt; 26 the app icon is shown correctly on all devices. But with <code>targetSdkVersion</code> >= 26 the app icon is shown inside a white circle on Android 8.0 devices.
  Is there a way to remove the white circle?</p>
