# Gson uses generic type information stored in a class file when working with # fields. Proguard removes such information by default, keep it. -keepattributes Signature # This is also needed for R8 in compat mode since multiple # optimizations will remove the generic signature such as class # merging and argument removal. See: # https://r8.googlesource.com/r8/+/refs/heads/main/compatibility-faq.md#troubleshooting-gson-gson -keep class com.google.gson.reflect.TypeToken { *; } -keep class * extends com.google.gson.reflect.TypeToken # Optional.
