How do I prevent my Android app from restarting on theme changes?

This skill guides you to include ConfigChanges.UiMode in your MainActivity's ConfigurationChanges attribute, which allows the app to handle theme changes without a full activity restart.

Can I implement more than just light and dark modes?

Yes, by using the ResourceDictionary swapping approach detailed in this skill, you can support multiple custom branded themes beyond the standard OS light/dark options.

Can I use this skill for localization or app icons?

No, this skill focuses strictly on visual theming. You should use maui-localization for language switching and maui-app-icons-splash for branding assets.

Does this skill support CSS-based styling in MAUI?

While it acknowledges MAUI supports CSS, it highlights that CSS themes cannot be swapped at runtime and recommends ResourceDictionaries for dynamic applications.

Should I use StaticResource or DynamicResource for theming?

For theme switching at runtime, you must use DynamicResource. StaticResource only evaluates once at load time and won't update when the theme changes.
