I temporarily want to disable night mode for my compose app. I have used this line to do so for colour scheme

val colourScheme = if (darkTheme) lightColourScheme else lightColourScheme

to enforce light colour scheme for now, but for obvious reasons this doesn't apply to res-night and I can still see the dark icons and other dark mode artefacts here and there.

What is the ideal way to enforce light mode only across the app?

[Ahmed]

Some solutions suggest inheriting from:

Theme.MaterialComponents.Light

And one of the solution is to use:

AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);

[Stylianos Gakis]

Perhaps just manually call
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES)
And uiModeManager?.setApplicationNightMode(UiModeManager.MODE_NIGHT_YES)

[Ahmed]

@Stylianos Gakis Thank you for the input. One of the comment said that using

AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES)

recreates he activity, so I was wondering if it was the ideal way to go ..

I guess I will just call this

[Ahmed]

Also, for some reason the above doesn't seem to work ^^^

[Ahmed]

I called it in onCreate of my launcher activity

[Stylianos Gakis]

It does recreate it if you don't opt out of config changes in your manifest, yes.

[Ahmed]

The line is not working for me 😅

[Stylianos Gakis]

Could you describe what you mean by "not working" 😅
What did you try, and what did happen instead?

[Ahmed]

I have tried calling the

AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES)

In onCreate() of Application and in onCreate() of my Launcher Activity (Main).

But the icons are still from the res-night if I dark mode is selected.

Keep in mind that AppCompatDelegate only affects AppCompatActivity - if you are extending ComponentActivity or FragmentActivity it won't do anything

[Ahmed]

Ah! Yes, I am indeed extending from ComponentActivity …

[Ahmed]

I assume that I should now extend from AppCompatActivity for my use-case?

[Ian Lake]

If you're working with AndroidView and want it themed correctly, you should probably be using AppCompatActivity, yes.

[Ahmed]

It is an 100% compose app with only the AndroidView used being NativeAdView . But yes, I can see nothing going wrong with using AppCompatActivity

[Ian Lake]

🤷‍♂️ you're the one using res-night. Only resource worth using in a 100% Compose app are strings

[Ahmed]

Is there an alternate/better way to use image resources for a compose app?

At some screens I do need the night version of resources.

[Ahmed]

Off-topic, but is something this ideal for compose?

class LightDrawables: Drawables
class DarkDrawables: Drawables

fun getDrawable(darkTheme: Boolean = isSystemInDarkTheme(), @DrawableRes drawableRes: Int) = if(darkTheme) DarkDrawables.xy else LightDrawables.xy

[Ian Lake]

I'd use ImageVector directly rather than go through resources at all if you can. It can help reduce recomposition too: https://engineering.teknasyon.com/reduce-recomposition-for-images-icons-in-jetpack-compose-8d2dd3bfa933

AndroidView used being NativeAdView

Still can't believe there's no first class support for google ads w/ compose
