### Gson ProGuard and R8 rules which are relevant for all users
|
|
### This file is automatically recognized by ProGuard and R8, see https://developer.android.com/build/shrink-code#configuration-files
|
|
###
|
|
### IMPORTANT:
|
|
### - These rules are additive; don't include anything here which is not specific to Gson (such as completely
|
|
### disabling obfuscation for all classes); the user would be unable to disable that then
|
|
### - These rules are not complete; users will most likely have to add additional rules for their specific
|
|
### classes, for example to disable obfuscation for certain fields or to keep no-args constructors
|
|
###
|
|
|
|
# Keep generic signatures; needed for correct type resolution
|
|
-keepattributes Signature
|
|
|
|
# Keep Gson annotations
|
|
# Note: Cannot perform finer selection here to only cover Gson annotations, see also https://stackoverflow.com/q/47515093
|
|
-keepattributes RuntimeVisibleAnnotations,AnnotationDefault
|
|
|
|
### The following rules are needed for R8 in "full mode" which only adheres to `-keepattribtues` if
|
|
### the corresponding class or field is matches by a `-keep` rule as well, see
|
|
### https://r8.googlesource.com/r8/+/refs/heads/main/compatibility-faq.md#r8-full-mode
|
|
|
|
# Keep class TypeToken (respectively its generic signature) if present
|
|
-if class com.google.gson.reflect.TypeToken
|
|
-keep,allowobfuscation class com.google.gson.reflect.TypeToken
|
|
|
|
# Keep any (anonymous) classes extending TypeToken
|
|
-keep,allowobfuscation class * extends com.google.gson.reflect.TypeToken
|
|
|
|
# Keep classes with @JsonAdapter annotation
|
|
-keep,allowobfuscation,allowoptimization @com.google.gson.annotations.JsonAdapter class *
|
|
|
|
# Keep fields with any other Gson annotation
|
|
# Also allow obfuscation, assuming that users will additionally use @SerializedName or
|
|
# other means to preserve the field names
|
|

@com.google.gson.annotations.Expose <fields>;

|
|
@com.google.gson.annotations.Since <fields>;
|
|
@com.google.gson.annotations.Until <fields>;
|
|
}
|
|
|
|
# Keep no-args constructor of classes which can be used with @JsonAdapter
|
|
# By default their no-args constructor is invoked to create an adapter instance
|
|
-keepclassmembers class * extends com.google.gson.TypeAdapter {
|
|
<init>();
|
|
}
|
|
-keepclassmembers class * implements com.google.gson.TypeAdapterFactory {
|
|
<init>();
|
|
}
|
|
-keepclassmembers class * implements com.google.gson.JsonSerializer {
|
|
<init>();
|
|
}
|
|
-keepclassmembers class * implements com.google.gson.JsonDeserializer {
|
|
<init>();
|
|
}
|
|
|
|
# Keep fields annotated with @SerializedName for classes which are referenced.
|
|
# If classes with fields annotated with @SerializedName have a no-args
|
|
# constructor keep that as well. Based on
|
|
# https://issuetracker.google.com/issues/150189783#comment11.
