android - Proguard 的 GSON 反序列化错误

Question

我有一个简单的类，其中包含如下列表:

public class Foo {
   @Expose
    private ClassA classa;

    @Expose
    private List<ClassB> list;
}

序列化和反序列化工作正常。但是，当我使用 ProGurad 混淆我的代码时我得到以下异常:

com.google.gson.JsonParseException: The Json Deserializer com.google.gson.DefaultTypeAdapters$CollectionTypeAdapter@406f6508 failed to deserialized json object [{...}, {...}, ...] given the type class java.util.List

Answer 1

您需要将这些行添加到您的混淆器中，以便在签署您的应用程序时保留 gson 类。

##---------------Begin: proguard configuration for Gson  ----------
# 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


# Gson specific classes
-keep class sun.misc.Unsafe { *; }
#-keep class com.google.gson.stream.** { *; }

# Application classes that will be serialized/deserialized over Gson
-keep class com.google.gson.examples.android.model.** { *; }

##---------------End: proguard configuration for Gson  ----------
