Question

我正在尝试在我的应用上设置proguard，我遇到以下错误：

java.lang.NoSuchMethodError: No static method getParameterized(Ljava/lang/reflect/Type;[Ljava/lang/reflect/Type;)Lcom/google/gson/reflect/TypeToken; in class Lcom/google/gson/reflect/TypeToken; or its super classes (declaration of 'com.google.gson.reflect.TypeToken' appears in /data/app/com.rw.crm.leads-1/base.apk)
                                                                                    at com.rw.crm.leads.model.response.GsonAdaptersResponse$ListResponseTypeAdapter.<init>(GsonAdaptersResponse.java:185)
                                                                                    at com.rw.crm.leads.model.response.GsonAdaptersResponse.create(GsonAdaptersResponse.java:36)
                                                                                    at com.google.gson.Gson.getAdapter(Gson.java:423)

我无法提出解决此问题的proguard配置。这就是我在gson proguard文件中所拥有的那一刻：

# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.
-keepattributes Signature

# For using GSON @Expose annotation
-keepattributes *Annotation*

# Gson specific classes
-dontwarn sun.misc.**

#-keep class com.google.gson.stream.** { *; }

# Application classes that will be serialized/deserialized over Gson
-keep class com.rw.crm.leads.model.** { *; }

# Prevent proguard from stripping interface information from TypeAdapterFactory,
# JsonSerializer, JsonDeserializer instances (so they can be used in @JsonAdapter)
-keep class * implements com.google.gson.TypeAdapterFactory
-keep class * implements com.google.gson.JsonSerializer
-keep class * implements com.google.gson.JsonDeserializer

# To make the app compile
-dontwarn com.google.gson.reflect.TypeToken

# Why doesn't this work?
-keep class com.google.gson.reflect.** { *; }

编辑：以下是build.gradle

的相关依赖项

compile "com.squareup.retrofit2:retrofit:2.3.0"
compile "com.squareup.retrofit2:converter-gson:2.3.0"

annotationProcessor "org.immutables:value:2.5.6"
provided "org.immutables:gson:2.5.6:annotations"

Answer 1

通过在我的gradle中包含最新的gson版本，我能够解决此错误： compile 'com.google.code.gson:gson:2.8.2'

这将是修复，直到任何一个库使用旧版本（immutables或retrofit2）更新他们的gson。

将Proguard应用于Retrofit2和GSONAdapters时出现致命错误
