我们正在用 kotlin 多平台制作公司的下一个项目。一切正常，直到我尝试为 android 创建一个发布版本进行 beta 测试。我在发布版本中收到此错误，而调试中一切正常。
[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.

如果你们需要任何东西，我很乐意提供
如果应用在调试中运行，但在发布中不起作用，则可能是因为 Proguard 缩小了您的类，并且由于不同(较短(的类和属性名称，反序列化不再有效。
确保在你的防护装置中有这个：
-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，说明如何将网络响应反序列化为数据类。
