小贝子编程

改造正文请求在改造中为空，当我使用 proguard 并启用缩小和收缩资源时



当我将minifyEnabled & shrinkResources设置为true时，发送的改造体 JSON 请求为空，当它设置为 false 时，它工作得很好。

我已经发布了整个gradle文件，以便您可以帮助我说出我做错了什么。

我的改造请求 json 正文在true时是这样的minifyEnabled & shrinkResources：

{}

当minifyEnabled & shrinkResourcesfalse时，它可以正常工作：

{"Data":"demoToken","Key":"demokey","Token":"2a9a8677-ac79-49d6-9947-d797b3e4d8e5"}

我的成绩看起来像这样：

以下是我的主要模型类

class ServiceRequest {
var Key: String? = "SiteAdminAppkey"
var Token: String? = ""
//    var Slug: String? = "admin"
var Data: Any? = null
}

我能够通过添加@SerializeName注释来使其工作，但我必须在每个模型类中执行此操作。在我的另一个项目中，Proguard 和所有内容都可以在没有序列化的情况下工作。

在proguard-rules.pro文件中添加以下行

-keepclassmembers,allowobfuscation class * {
@com.google.gson.annotations.SerializedName <fields>;
}

还要在 gradle.properties 文件中添加以下行。

android.enableR8=false

我面临同样的问题，并在文件中添加了上面的行，它对我有用。

在 proguard-rules 中添加以下行

-keepclassmembers class <yourpackagename>.** { <fields>; }

将 yourpackageName替换为所有模型类的目录路径，就像我的情况一样

-keepclassmembers class com.demo.app.model.** { <fields>; }

这就是对我有用的。

# Retrofit2
-keepclasseswithmembers class * {
@retrofit2.http.* <methods>;
}
-keepclassmembernames interface * {
@retrofit2.http.* <methods>;
}
# GSON Annotations
-keepclassmembers,allowobfuscation class * {
@com.google.gson.annotations.SerializedName <fields>;
}

出于某种原因，如果没有 GSON 注释设置，它不起作用，即使直接在模型类上添加@Keep注释也是如此。

由于您使用Gson将Json转换为模型，因此您需要确保反射在这些类上正常工作(因为我假设您尚未为这些类创建自定义适配器(。

保留类名和字段名的最简单方法是，您可以使用AndroidX 注释中的@Keep对模型进行注释：

表示在生成时缩小代码时不应删除带批注的元素。这通常用于仅通过反射访问的方法和类，因此编译器可能会认为代码未使用。

这是一个更新的答案(05/20(，因为在我的情况下似乎没有任何效果。

  1. 在此处使用改造文档中的 Proguard 规则。

  2. 保持你的模型类像周汉的答案。

以上答案都适用于 gson。 但是我在使用 kotlinx 序列化时遇到了同样的问题。

这需要一组不同的条目进入 proguard-rules，如 kotlinx 序列化文档中的此处所示。

# Keep `Companion` object fields of serializable classes.
# This avoids serializer lookup through `getDeclaredClasses` as done for named companion objects.
-if @kotlinx.serialization.Serializable class **
-keepclassmembers class <1> {
static <1>$Companion Companion;
}
# Keep `serializer()` on companion objects (both default and named) of serializable classes.
-if @kotlinx.serialization.Serializable class ** {
static **$* *;
}
-keepclassmembers class <2>$<3> {
kotlinx.serialization.KSerializer serializer(...);
}
# Keep `INSTANCE.serializer()` of serializable objects.
-if @kotlinx.serialization.Serializable class ** {
public static ** INSTANCE;
}
-keepclassmembers class <1> {
public static <1> INSTANCE;
kotlinx.serialization.KSerializer serializer(...);
}
# @Serializable and @Polymorphic are used at runtime for polymorphic serialization.
-keepattributes RuntimeVisibleAnnotations,AnnotationDefault
# Serializer for classes with named companion objects are retrieved using `getDeclaredClasses`.
# If you have any, uncomment and replace classes with those containing named companion objects.
#-keepattributes InnerClasses # Needed for `getDeclaredClasses`.
#-if @kotlinx.serialization.Serializable class
#com.example.myapplication.HasNamedCompanion, # <-- List serializable classes with named companions.
#com.example.myapplication.HasNamedCompanion2
#{
#    static **$* *;
#}
#-keepnames class <1>$$serializer { # -keepnames suffices; class is kept when serializer() is kept.
#    static <1>$$serializer INSTANCE;
#}

  • 使用最新版本的改造库： com.squareup.retrofit2：retrofit：2.7.1 如果您使用的是 R8，则会自动包含收缩和混淆规则。 最新改造库

  • 此外，Gson 实现中的更改 'com.google.code.gson：gson：2.8.6' 最新的 GSON 库

  • 查看 R8 兼容性常见问题解答 适用于 GSON 的 R8-兼容性常见问题解答

  • 如果您使用的是 OkHttp3，请更改为最新版本 okhttp3LibVersion = '4.3.1

就我而言，这是解决方案：

# For GSON annotation
-keepclassmembers,allowobfuscation class * {
@com.google.gson.annotations.SerializedName <fields>;
}
