Preview Composables are not removed by R8

[kevinguitar]

Describe the bug

Hello, I noticed there are a bunch of preview composables that got packaged in the final APK on an Android app that is using purchases-kmp.

I added a rule in proguard to validate that there are no previews being kept

# Ensure all Previews have been stripped https://issuetracker.google.com/issues/157891235#comment6
-checkdiscard class * { @androidx.compose.ui.tooling.preview.Preview <methods>; }
-keepclassmembers,allowshrinking class * { @androidx.compose.ui.tooling.preview.Preview <methods>; }

And there are a lot of previews kept when you assemble a release build:

Some environmental information:

• Platform: Android
• SDK version: 3.0.3
• IDE: Android Studio
• IDE version: Quail 1 | 2026.1.1

Hi @kevinguitar, thanks for raising this! We'll take a look and get back to you soon!

Sorry for the inconvenience @kevinguitar, it looks like this is a result of our proguard rules in the underlying https://github.com/RevenueCat/purchases-android. I agree this is not ideal.

I've created a ticket for tracking this internally, hopefully we should be able to address this soon.

Thanks again for raising this and we'll keep you posted.

No problem, thanks @rickvdl !
