This is highly dependent on the launcher you use. The image looks like the standard google android 8+ (?) icon shape. I theory it could be part of the icon you created but since you are asking this I doubt it.

In older versions of android the outer shape of the icons were individual, while rather cool and the outline correctly shown while dragging them etc many complained about the lack of a uniform look of all the icons in the app drawer etc.

It was introduced to make all icons seem more uniform. Long pressing an empty space in the Google Pixel launcher for example shows a choice to go into the settings for the launcher and there you can change the shape all icons should have:

In addition to this, apps can take advantage of the various shapes and adapt to them and fill them out so to speak. See for example the Chrome icon while changing the icon shapes in the launcher settings.

Introduced in android 8: The feature is called adaptive icons.

See the docs about adaptive icons here: https://developer.android.com/guide/practices/ui_guidelines/icon_design_adaptive
