【中文标题】android kotlin multiplatform kotlinx.serialization 适用于调试但不适用于发布版本【英文标题】：android kotlin multiplatform kotlinx.serialization works on debug but does not work on release version 【发布时间】：2020-10-19 14:55:30 【问题描述】：我们正在使用 kotlin 多平台在公司制作下一个项目。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。

这里是项目级 build.gradle

如果你们需要什么我很乐意提供
【问题讨论】：
【参考方案1】：如果应用程序在调试中工作但在发布时不工作，这可能是因为 Proguard 缩小了您的类，并且由于类和属性名称不同（较短）而反序列化不再工作。
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。
