Enums 如何使枚举在启用proguard的情况下工作？

我开发了一个android应用程序，在许多模块中使用enum。现在我正试图保护我的应用程序不受反向工程的影响，为此，我在应用程序中启用了proguard，但问题是在启用proguard后，无论我在哪里使用枚举，我的应用程序都会崩溃。 我创建了以下类来定义所有枚举

package app.mypackagename.utils;

import android.content.Context;

public class EnumUtils {

    public static enum AppDomain {
        LIVE, STAGING, MOCK
    }

    public static enum UserRole {
        CUSTOMER, ADMIN;

    }
    public static enum Module {
        REGISTRATION, PRODUCT
    }

}

枚举“UserRole”正在模型类“User”中使用

成功登录后，我将使用以下代码检查用户角色

                            Gson gson = new Gson();
                            Type listType = new TypeToken<User>() {
                            }.getType();
                            onlineUser = ((User) gson.fromJson(taskItem.getRawResponse(),
                                    listType));
                            onlineUser.userID = userId;
                            if (onlineUser.sulLevelcode.equalsIgnoreCase(Constants.LEVEL_CODE_CUSTOMER)) {
                                onlineUser.userRole = EnumUtils.UserRole.CUSTOMER;
                            }

有人能帮我解决这个问题吗。任何帮助都将不胜感激。

我也遇到了同样的问题，但将这一行添加到我的proguard-rules.pro中仍然有效-

-keep class app.mypackagename.constants.* { <fields>; }.   

-保留类app.mypackagename.constants.*{；}。

其中“app.mypackagename.constants”是我的所有枚举所在的包。
