Hi, got a Compose Preview problem.

Our default res/values/strings.xml is Polish, with translations in values-en, values-cs, values-de etc. So Polish is the base/fallback language.

The thing is Preview in Android Studio renders everything in English by default. Its default locale resolves to en-US, so it picks values-en instead of the base values/. I'm pretty sure this worked correctly (defaulted to the base language) a few Android Studio versions ago.

What I've tried so far:
• tools:locale="pl" on <resources> in values/strings.xml. Preview still shows English.
• res/resources.properties with unqualifiedResLocale=pl-PL. No effect on Preview at all.

The only thing that works is setting it per-preview is @Preview(locale = "pl")

Is there a project or IDE level way to set the default Preview locale so it falls back to the base values/ (Polish), instead of adding locale="pl" to every @Preview?

I'd just create my own custom preview annotation which has this default built-in, along with whatever else you typically need as a default like both dark and light mode etc

I'll likely take that approach in the end, but since it requires editing dozens of files in my project, I was hoping to find an alternative. The root cause clearly lies in Android Studio or compose tooling lib, which assumes the default locale is always en-US and forces it.

It's a refactor where you'd just do a find and replace everywhere where you used the default preview, so it shouldn't be that bad

KDoc says that the default folder will be used. If that's not what you're seeing I'd raise a bug.

[Rafał Borcz]

But what does default mean here? If the documentation is referring to res/values folder without any qualifier, then it clearly doesn't work, and this is probably a bug. I'll try to report it.
