多个 JSON 字段仅在“RELEASE”构建模式下命名为异常

Question

这很奇怪，但是 序列化在 DEBUG 构建模式以及除一个 之外的所有 API 响应中完成得非常好。但是在发布模式下，它会抛出非法参数异常。

这是此异常的完整日志：

到目前为止我尝试了什么？

我已经尝试并在同一父项中查找多个 JSON 字段 class 但没有找到。
检查每个字段的@SerializedName 是否不同。

我还在发布模式下启用了 proguard。

之前它运行良好（没有启用 proguard）并且我没有收到任何编译时错误。

Answer 1

如果调试模式正常运行并且发布是问题，那么很可能是混淆器问题。尝试从混淆中排除 SellerStoreFormData。

此外，请检查您是否有 proguard Gson configuration，如果没有，请添加它。
