In android the icon expands

### :information_source: Info
Version: 2.0.5

### :speech_balloon: Description
When I generate icons in ios they appear exactly the same size as my icon.png. The problem is that on android they look much larger once you install the application on a device.

Could you add a default margin to the icons in android so that the icon fits the size it should be?
