在我的项目上运行proguard后一切都很顺利，但我遇到了问题。我在规则中使用gson规范，但我仍然遇到这种错误。通常这段代码效果很好。嗯，任何人都有任何想法吗？

答案 0 :(得分：0)
我将此配置用于我的GSON程序，尝试并让我知道
## GSON 2.2.4 specific rules ##
# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.
-keepattributes Signature
# For using GSON @Expose annotation
-keepattributes *Annotation*
-keepattributes EnclosingMethod
# Gson specific classes
-keep class sun.misc.Unsafe { *; }
-keep class com.google.gson.stream.** { *; }
