当我在GSON上运行Proguard时应用程序崩溃（使用枚举）

Question

我在我的Android应用程序中使用GSON来解析数据。我已经在模型对象中添加了枚举。添加枚举后，我的应用程序开始崩溃。当我让runProguard假的时候，一切都很好。当程序是真的时，我做了我能在网上找到的一切来修复这个问题。但还是没运气。

我已经在proguard-rule文件中做了以下事情

-keep class com.google.** { *; }

-keepattributes *Annotation*
-keepattributes Signature

-keepclassmembers enum * { public static **[] values(); public static ** valueOf(java.lang.String); }

枚举材料示例：

public enum TypeX {
@SerializedName("live")
LIVE,

@SerializedName("upcoming")
UPCOMING,

@SerializedName("replay")
REPLAY; }
