R8 fullmode Causes java.lang.RuntimeException: Invalid TypeToken; must specify type parameters

[Daniel Waiguru]

Using Kodein 6.2.1 with r8 fullmode enabled causes this crash

You can add pro guard rules like
https://kosi-libs.org/kodein/7.21/framework/android.html#_proguard_configuration.

Latest versions of Kodein embed them already.

[Daniel Waiguru]

I have added these rules but still the error persists

[Romain Boisselle]

I'll have a look. Trying to reproduce.

[Romain Boisselle]

Also, why are you on Kodein 6.2.1?
Did you try to add proguard rules for TypeReference?

[Daniel Waiguru]

Updating the Kodein version necessitates regression testing which is not in the pipeline, I have these rules https://kosi-libs.org/kodein/7.21/framework/android.html#_proguard_configuration in my proguard rules

[Romain Boisselle]

Those rules only apply for 7.6+. Old Kodein versions have a different type system. So the rules should be different. You should add TypeReference to your rules.

[Daniel Waiguru]

Can I kindly get the rules I need for Kodein 6.2.1

[Romain Boisselle]

I don't really know, looking at old code here, here and here, rules could be those:

-keep, allowobfuscation, allowoptimization class org.kodein.di.Typed
-keep, allowobfuscation, allowoptimization class org.kodein.di.TypeToken
-keep, allowobfuscation, allowoptimization class org.kodein.di.CompositeTypeToken
-keep, allowobfuscation, allowoptimization class org.kodein.di.JVMTypeToken
-keep, allowobfuscation, allowoptimization class org.kodein.di.WrappingTest

-keep, allowobfuscation, allowoptimization class * extends org.kodein.di.Typed
-keep, allowobfuscation, allowoptimization class * extends org.kodein.di.TypeToken
-keep, allowobfuscation, allowoptimization class * extends org.kodein.di.CompositeTypeToken
-keep, allowobfuscation, allowoptimization class * extends org.kodein.di.JVMTypeToken
-keep, allowobfuscation, allowoptimization class * extends class org.kodein.di.WrappingTest
