### Rules required for Shake
######
# Keep Shake classes from second obfuscation
-keep public class com.shakebugs.shake.** { *; }

# Keep mp4parser boxes package classes
-keep public class org.mp4parser.boxes.** { *; }

# Keep Gson LinkedTreeMap class

### Retrofit - last version doesn't support R8 full mode yet, can be removed later.

# Retrofit does reflection on generic parameters. InnerClasses is required to use Signature and
# EnclosingMethod is required to use InnerClasses.

# Retrofit does reflection on method and parameter annotations.
-keepattributes RuntimeVisibleAnnotations, RuntimeVisibleParameterAnnotations

# Keep annotation default values (e.g., retrofit2.http.Field.encoded).

# Retain service method parameters when optimizing.

### Gson - last version doesn't support R8 full mode yet, can be removed later.
######

# 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 *Annotation*


### 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)
-keep class com.google.gson.reflect.TypeToken { *; }

# Keep any (anonymous) classes extending TypeToken
-keep class * extends com.google.gson.reflect.TypeToken

# Keep classes with @JsonAdapter annotation
-keep @com.google.gson.annotations.JsonAdapter class *

# Keep fields with @SerializedName annotation, but allow obfuscation of their names
-keepclassmembers,allowobfuscation class * {
  @com.google.gson.annotations.SerializedName <fields>;
}

# Keep fields with any other Gson annotation
-keepclassmembers class * {
  @com.google.gson.annotations.Expose <fields>;
  @com.google.gson.annotations.JsonAdapter <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
-keep class * extends com.google.gson.TypeAdapter {
  <init>();
}
-keep class * implements com.google.gson.TypeAdapterFactory {
  <init>();
}
-keep class * implements com.google.gson.JsonSerializer {

-keep class * implements com.google.gson.JsonDeserializer {
