android-导航组件 Parcelable 参数在发布变体上找不到答案

【问题标题】：android- navigation component Parcelable arguments not found on release variantandroid-导航组件 Parcelable 参数在发布变体上找不到
【发布时间】：2021-11-24 18:46:38
【问题描述】：

我有一个奇怪的错误，我正在开发一个应用程序，我正在使用navigation component，我需要使用safeArgs 将自定义Parcelable 对象传递给一些片段，实际上该应用程序在调试版本上运行良好，不幸的是，当试图在发布模式下启动应用程序时，应用程序会抛出一个 FATAL EXCEPTION。模型在一个单独的模块中，我需要在这个模块中添加特定的配置吗？

这是模型的示例

@Parcelize
@Serializable
data class Article(
    val articleId: Int,
///
) : Parcelable

这是异常的堆栈跟踪：

注意：我已将包名替换为 3 个点谢谢你

【问题讨论】：

你需要添加 Proguard 配置来保留你的类的名字被@Parcelize 或实现Parcelable 左右

标签： android parcelable

【解决方案1】：

您需要至少将以下内容添加到您的 Proguard 配置中：

-keepnames class * implements android.os.Parcelable

尽管确保保留 CREATOR 字段也很有意义

-keepnames class * implements android.os.Parcelable

-keepclassmembers class * implements android.os.Parcelable {
    public static final ** CREATOR;
}

-keepnames class * implements android.os.Parcelable {
    public static final ** CREATOR;
}
