Looks like something is wrong with resources

[pelmenstar1]

I think I found the reason.

Here is how the theme is initialized:

Compose-Settings/app/src/main/java/com/alorma/compose/settings/example/ui/theme/Theme.kt

Lines 11 to 33 in 84b08ed

	@Composable
	fun ComposeSettingsTheme(
	darkThemePreference: Boolean,
	dynamicThemePreference: Boolean,
	content: @Composable () -> Unit,
	) {
	MaterialTheme(
	colorScheme = if (dynamicThemePreference) {
	if (darkThemePreference) {
	dynamicDarkColorScheme(LocalContext.current)
	} else {
	dynamicLightColorScheme(LocalContext.current)
	}
	} else {
	if (darkThemePreference) {
	darkColorScheme()
	} else {
	lightColorScheme()
	}
	},
	content = content
	)
	}

The problem is it just checks whether dynamicThemePreference is true. But it doesn't check the API level even though both dynamicDarkColorScheme and dynamicLightColorScheme require API level 31. By default, dynamicThemePreference is true regardless of the API level.

I launched the app on API level 28, so that's why the problem emerged. If dynamicThemePreference is disabled manually, everything works fine.

I will create a fix soon.
