Frequently Asked Questions
Adaptive Icons (Android 8.0+) use two layers — foreground and background — so the OS can apply different shaped masks (circle, squircle, rounded square) depending on the device. This tool generates both layers automatically, shows you a preview with all three mask shapes, includes safe zone guides, and exports the ic_launcher.xml files ready for your Android project.
