I’ve created some templates for the new Android O adaptive icons. Adaptive icons are pretty different to the current Android app icons. Adaptive icons are masked by the launcher, the mask can be a range of shapes, and the icons now have two layers to assist with animation and open up more possibilities for their use.
The templates are available for Photoshop, Sketch, Illustrator and Affinity Designer. All free and open source under the BSD license (do whatcha like).
Please let me know if you have any questions. Feedback welcome.
