Proguard混淆注释 [英] Proguard obfuscating Annotations

问题描述

我需要使所有模型类保持一致，因此我在proguard规则中添加了以下行以保留所有模型类:

I need to keep all model classes to be unobfuscated, so I added this line in proguard rules to keep all model classes:

-keep class my_package_name.model.** { *; }

此命令将保留所有模型类，但是仍然混淆了模型类内部的注释.我尝试添加以下行:

All model classes are getting kept by this command but still, it is obfuscating the annotations inside the Model classes. I tried adding the following line:

-keepattributes *Annotation*
-keepattributes EnclosingMethod

但是结果还是一样.我的模型类包含以下两个注释:

But still, results are same. My model classes contain these two annotations:

@SerializedName("message")
@Expose
private String message;

如何使两个注释保持一致?

How can I keep the two annotations unobfuscated?

推荐答案

Gson在使用字段时会使用存储在类文件中的泛型类型信息.Proguard默认会删除此类信息，因此请将其配置为保留所有信息.

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.

尝试添加

-keepattributes Signature
-keepattributes EnclosingMethod
-keepattributes InnerClasses
-keepattributes Annotation

用于使用GSON @Expose注释

For using GSON @Expose annotation

-keepattributes *Annotation*

针对Gson特定班级

-keep class sun.misc.Unsafe { *; }

防止proguard剥离TypeAdapterFactory，JsonSerializer，JsonDeserializer实例的接口信息(因此可以在@JsonAdapter中使用它们)

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
