android kotlin multiplatform kotlinx.serialization 适用于调试但不适用于发布版本

Question

我们正在使用 kotlin 多平台在公司进行下一个项目。一切正常，直到我尝试为 android 测试创建一个发布版本。我在发布版本中遇到此错误，而在调试中一切正常。

[NetworkManager] unknown exception: l.a.w: Can't locate argument-less serializer for class a. For generic classes, such as lists, please provide serializer explicitly.

这是项目级别的 build.gradle

buildscript {
ext.kotlin_version = '1.3.70'
ext.versions = [
        "ktor" : "1.3.2",
        "serialization" : "0.20.0",
        "coroutines" : "1.3.6",
]

如果你们需要什么我很乐意提供

Answer 1

如果应用程序在调试中工作但在发布中不能工作，这可能是因为 Proguard 缩小了你的类，并且由于不同的(更短的)类和属性名称，反序列化不再起作用。
确保你的 proguard 中有这个:

-keepattributes *Annotation*, InnerClasses
-dontnote kotlinx.serialization.SerializationKt
-keep,includedescriptorclasses class com.yourcompany.yourpackage.**$$serializer { *; } # <-- change package name to your app's
-keepclassmembers class com.yourcompany.yourpackage.** { # <-- change package name to your app's
    *** Companion;
}
-keepclasseswithmembers class com.yourcompany.yourpackage.** { # <-- change package name to your app's
    kotlinx.serialization.KSerializer serializer(...);
}

如果反序列化仍然失败，请提供一个示例，说明您如何将网络响应反序列化为数据类。
