Idea of Cancel Icon
The icon is a common symbol for expressing denial of permission. It consists of a circle with a large X in the center of it, symbolizing the cancellation of an already-running action.

. If you use the icons for Android apps, we recommend using our latest Material Icons icon pack (please check our sidebar on the right). Otherwise, it's a solid icon pack that looks good in small resolutions, either on the web or in print. It's characterized by thick lines, smooth corners, and is optimized for 24x24 pixels.
