android - Proguard for Wire + 改造 NoSuchMethodException

Question

我的脑袋炸了。我搜索了 S.O.寻求帮助，但此异常的 Proguard 问题似乎特定于相关应用程序。我一直在尝试使用 Proguard 混淆/缩小我的应用程序，当我在生成的 APK 表单中运行它时，我的应用程序要么崩溃，要么出现以下问题:

com.company.project E/a: java.lang.NoSuchMethodException: fromValue [int]

堆栈跟踪:

我的应用程序使用来自 Square 的 Retrofit (2.1.0) 和 Wire。然后，当我的应用程序崩溃时，我正在检查 mapping.txt 文件以查看导致问题的类(我相信它是 com.company.project.a，对吧？ )

无论如何，这是我的 proguard 文件(带有晦涩的类名 fyi):

-dontwarn okio.**
-dontwarn retrofit2.Platform$Java8
-dontwarn retrofit2.**
-keep class retrofit2.** { *; }
-keep class com.squareup.wire.** { *; }
-keep class com.company.project.utils.wiremodels.ProtoFile1 { *; }
-keep class com.company.project.utils.wiremodels.ProtoFile2 { *; }
-keep class com.company.project.utils.wiremodels.ProtoFile3 { *; }
-keep class com.company.project.utils.wiremodels.ProtoFile4 { *; }
-keep class com.company.project.utils.wiremodels.ProtoFile5 { *; }
-dontwarn com.google.**
-keepattributes Signature
-keepattributes *Annotation*
-keepattributes Exceptions
-dontwarn org.w3c.dom.bootstrap.DOMImplementationRegistry
-dontwarn org.simpleframework.xml.stream.**

如果我能在这方面得到一些帮助，那就太好了，如果我应该提供更多信息，请告诉我。

你可以在某些类中保留方法:

-keepclassmembers,allowobfuscation class com.company.project.yourClass.** {
    <methods>;
}

当您使用 wire 时，表格 these indications proguard 推荐的是:

-keep class com.squareup.wire.** { *; }
-keep class com.yourcompany.yourgeneratedcode.** { *; }

如果问题来自retrofit here is a proguard example :

-keep class com.squareup.okhttp.** { *; }
-keep class retrofit.** { *; }
-keep interface com.squareup.okhttp.** { *; }

-dontwarn com.squareup.okhttp.**
-dontwarn okio.**
-dontwarn retrofit.**
-dontwarn rx.**

-keepclasseswithmembers class * {
    @retrofit.http.* <methods>;
}

# If in your rest service interface you use methods with Callback argument.
-keepattributes Exceptions

# If your rest service methods throw custom exceptions, because you've defined an ErrorHandler.
-keepattributes Signature
