当我在GSON上运行Proguard时应用程序崩溃（使用枚举）

json android java gson assertion

我正在我的Android应用程序中使用GSON来解析数据。我已经在我的模型对象中添加了一个枚举。添加枚举后，我的应用开始崩溃。当我使runProguard假时，一切都很好。当程序属实时，我尽我所能在互联网上找到解决问题。但仍然没有运气。

我已经在proguard-rule文件中完成了以下事情

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

-keepattributes *Annotation*
-keepattributes Signature

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

枚举内容示例：

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

@SerializedName("upcoming")
UPCOMING,

@SerializedName("replay")
REPLAY; }

我的堆栈跟踪

答案 1

应使用以下规则解决此问题：

-keepclassmembers enum * { *; }

或使用以下方法：

-keepclassmembers enum com.your.package.** { *; }

答案 2

我通过在我的proguard规则文件中添加这些规则解决了这个问题：

    # GSON.
-keepnames class com.google.gson.** {*;}
-keepnames enum com.google.gson.** {*;}
-keepnames interface com.google.gson.** {*;}
-keep class com.google.gson.** { *; }
-keepnames class org.** {*;}
-keepnames enum org.** {*;}
-keepnames interface org.** {*;}
-keep class org.** { *; }

-keepnames class com.yourpackagename.net.** {*;}
-keepnames enum com.yourpackagename.net.** {*;}
-keepnames interface com.yourpackagename.net.** {*;}
-keep class com.yourpackagename.net.** { *; }

-keepattributes Signature
-keepattributes *Annotation*
-keep class sun.misc.Unsafe { *; }
-keep class com.google.gson.stream.** { *; }

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