+To create template [Adaptive Icons for Android](https://developer.android.com/guide/practices/ui_guidelines/icon_design_adaptive) include the `--adaptive-icons` flag.

+To test how adaptive icons will look when animated, swiped, etc, the [Adaptive Icons](https://adapticon.tooo.io/) website by [Marius Claret](https://twitter.com/mariusclaret) is very useful!

 ### Generating Icons
 
 Add an icon (ideally at least 192x192 pixels) named `icon.png` to your project root (or run `app-icon init`). To automatically generate icons of all sizes for all app projects in the same folder, run:

bin/app-icon.js
