Android Adaptive Icons

Android allows us to create adaptive icons (various shapes for one icon for different devices) for:

• launcher icons
• shortcuts
• Setting app
• sharing dialogs
• overview screen

You have to provide the following layers 108x108 dp:

• top mask (circle, squircle, rounded square, square) provided by device OEM (e.g. Samsung)
• foreground layer 72x72 dp should be visible in the mask viewport
• background layer

The edge 18 dp are reserved for system's special effects.

Use Android Studio 3.0 Asset Studio to create these adaptive icons.
