Copy code
-keep class com.sdk.growthbook.** { *; }

-keepattributes *Annotation*, InnerClasses
-dontnote kotlinx.serialization.SerializationKt
-keep,includedescriptorclasses class com.sdk.growthbook.**$$serializer { *; }
-keepclassmembers class com.sdk.growthbook.** {
    *** Companion;

In 1.1.34 we disabled minifacation. So, with 1.1.34 it returns correct values but there is out of memory in CI, right?

You are using our library in your own library (not an app), right?

yes. we wrapped it in a module

Copy code
ERROR:R8: java.lang.OutOfMemoryError: GC overhead limit exceeded
is it all? maybe heap size in your CI?
a

acoustic-afternoon-96978

07/07/2023, 10:06 AM
the heap size is
Copy code
org.gradle.jvmargs=-Xmx16g
on a 8 core linux machine on github. it was working fine if we added this in
Copy code
-keep class com.sdk.growthbook.** { *; }
in our rules. but then the sdk is failing to retrieve the data

which version of growthbook-kotlin you used when you added our lib first?
a

acoustic-afternoon-96978

07/07/2023, 10:12 AM

I want to discuss this case:
Copy code
-keep class com.sdk.growthbook.** { *; }
So, you have some feature. You turns feature on but, in your app false is received, right?

acoustic-afternoon-96978

07/07/2023, 10:41 AM
yeah, 100% of the time

I just checked feature flags. It works when minification is disabled. It was checked in pure Android app. Maybe separate module (wrapper module as was mentioned) adds additional complexity.
Kevych Solutions team investigated how the library works with minification enabled and disabled. It was clear that with minification enabled there were troubles with serialization. We found some proguard rule to fix it. Rule works at least for us and Ahmed. @acoustic-afternoon-96978 could you please specify here if this issue is closed for now?
My pleasure
