Why aren't my theme changes firing on Android?

This skill highlights the requirement of adding ConfigChanges.UiMode to your MainActivity, which is necessary for the OS to notify your MAUI app of theme changes.

Can I use this for both XAML and C# UI development?

Absolutely. The skill includes guidance for XAML markup extensions like AppThemeBinding as well as C# extension methods like SetAppThemeColor.

Does this skill support runtime theme switching?

Yes, it provides implementation patterns for swapping ResourceDictionaries dynamically using MergedDictionaries and DynamicResource bindings.

What is the difference between AppThemeBinding and DynamicResource?

AppThemeBinding is used specifically to switch between Light and Dark values based on system settings, while DynamicResource is used to reference values that may change at runtime, such as when swapping a full theme dictionary.
