To get Compose preview to work I need this dependency: implementation "androidx.compose.ui:ui-tooling:$compose_version" But then that means that library will increase the size of my production build. Is there a way around this?

R8 should clean everything

Cheers. I guess so. I should start using it!

should have already, you said you already published the app 😧

However, users concerned in packaging

PreviewActivity in their release builds and/or worried about the APK size

impact caused by ui-tooling now have the option to add ui-tooling-preview as

an implementation API and ui-tooling as debugImplementation. PreviewActivity

won't then be part of the release APK, and its size shouldn't increase too

much, since ui-tooling-preview should be much smaller than ui-tooling.

[Albert Chang]

ui-tooling contains PreviewActivity which is defined in AndroidManifest.xml so it won't be stripped by R8.

Thanks Albert.

It's open source, Sergei. I have no desire to obfuscate it. But if it helps performance I'll give it a go. Performance seems fine currently, however.

You should surely use R8.
