Question: react-native android app icons: why isn't the empty space around the image preserved?

[Yossi]

I have created icons for a react-native app on android.

For example, this is the xxxhdpi icon. The black frame is not part of the image.
It is just for showing the white margins around it:

When I install the app, the white margins are removed and the image is displayed as follows on Android 8 (the black background is the wallpaper):

I expected the white margins to be kept. How do I keep it?

@rahamin1 You have to use adaptive icons for android, so that the icon adapts to a circular shape, with rounded edges, etc.
In the documentation there is a link to review just the topic:
