The icon shows a square shaped loop that is made up of two arrows moving in a counter clockwise direction. This would represent a repeating of a cycle or the current operation.
This Repeat icon has Android KitKat style
. 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.
