The APK was showing just a purple circle because the legacy launcher PNG files
(ic_launcher.png and ic_launcher_round.png) were solid purple with no logo.
Changes:
- Update generate-icons.sh to generate legacy launcher PNGs (for Android < 8.0)
- Add ImageMagick as fallback SVG renderer when inkscape/rsvg unavailable
- Replace 'bc' calculations with bash arithmetic for better compatibility
- Generate both square and round launcher icons with white logo on purple bg
- Regenerate all launcher icons (mdpi, hdpi, xhdpi, xxhdpi, xxxhdpi)
The icons now properly display:
- Purple background (#7c52e0)
- White Ditto logo (66% safe zone sizing)
- Round variant with circular mask
This fixes the issue for both:
- Modern devices (Android 8.0+): Uses adaptive icon system with vector foreground
- Legacy devices (Android < 8.0): Uses pre-rendered PNG launcher icons
